/diy/ - Do It Yourself

Soldering a motor to an ESC - I have banana plugs, but they lack a "sheath". This means that once they are plugged in, it is possible for them to short on eachother. I could just shrink tube them, but I figure there is probably a better way. How do people usually do this?

>>1993179
Either heatshrink (you can do each half individually, so they can still be disconnected, or just cover the whole thing in one piece) or just cut them off & direct solder.

>>1993183
I was going to do each half with heatshrink- I'll just make sure there isn't any metal showing.

>>1993183
Thanks it turned out great

>20 different chargers

Wtf. One charger does literally every single battery I use in this hobby, except for the 18500 I use in my radio.

I just ordered this bad boy, planning to get into large camera FPV stuff.

I've decided on the following parts so far:

Caddx Ratel 1
Unify Pro32 HV
FrSky R9MM with ExpressLRS

The only thing I'm still debating is motors.

Emax ECO II 2807 1300KV go for $16 each.
I know you people usually recommend iFlight XING, but the price difference for 8 motors and a spare would be almost $200.

Do you think I can get away with the ECOs? I'm not looking to crash this quad, so durability isn't really my main concern.

Can anyone maybe help me decipher why my newest quad won't arm? For the longest time it was telling me the craft wasn't level enough to arm, I fixed that, also fixed the throttle apparently being too high. Now it still won't arm and just gives me a series of beeps when I try, no arm disable codes in betaflight.

>>1993390
Why ExpressLRS? If you're carrying an expensive camera you want reliability, not super low racing latency.

>>1993488
ExpressLRS on 50hz has the best range, and it's probably just as reliable as FrSky R9.
ExpressLRS isn't ONLY focused on low latency racing.

I don't have any other options. What do you suggest?

>>1993163
Is there a drone that isn't dirt cheap to fly around my house? Like around $150-$225 range?

Friendly Reminder

If you're not follwoing the law you are a criminal.

>>1993543
There's no way in hell that a relatively nascent community developed firmware is as stable or reliable as a mature commercial platform that's been field proven for years by a userbase thousands of times the size. Just use R9.

>>1993569
Do you have a radio? Charger? Goggles/monitor? Or are you starting from scratch?

>>1993607
Seriously, just fuck off. It's obvious now that you're just one sad little troll who visits these threads for the sole purpose of trying to stir up pointless squabbling over rules.

>>1993611
>Do you have a radio? Charger? Goggles/monitor? Or are you starting from scratch?
Bro I have nothing. I haven't even thought about it till this thread. But it would help with looking at the roof or planning a landscape job.

>>1993611
I'm not going to flash my R9M back and forth between ELRS and FrSky.

Going to look out for a used R9M to use exclusively for OG FrSky firmware, although I really do trust ELRS. I see your point, but IIRC even R9 had problems when it was first released.

Also they are using LORA, it's not like they cooked up the whole thing from scratch.

>>1993611
Any comment on the initial question regarding motors though?

>>1993628
>I'm not going to flash my R9M back and forth between ELRS and FrSky.

Ah, didn't realise you're using it for other models.

>even R9 had problems when it was first released

I've used R9 pretty much since launch & even back then when people were complaining about having to do frequent firmware updates, it never had any problems that actually affected stability, failsafes, range, etc. And even if it did, that was 3 years ago & doesn't apply at all to the current state of the platform.

>>1993632
Don't really know anything about them, sorry. What sort of camera are you planning to lift though? Because saving $200 on motors if you're strapping a $5000 camera to the thing seems like it would be false economy.

>>1993655
Probably not $5000
Blackmagic Pocket or Micro, so approximately $1000 plus glass.

I don't suppose the ECOs will be more prone to failure. They also aren't bad in terms of efficiency according to Drone Mesh on YT. My main concern is about smoothness and balance, really.

I'm a fag and love DJI products but might be switching after the new FAA regs start going hot in 18 months.

Hey frens, does anyone know if the eachine ev300o can charge a battery that's connected to them through the USB-C port?

>>1993817
Not sure I understand you - are you saying you want to have a battery connected to USB, plus a power supply connected to the DC input, then for the DC input to charge the USB battery?

I went down the rabbit hole of seeing replacing mosfets on an ESC to looking at open source ESCs

I saw a 24V (5-6s) 24A brushless ESC which showed the components on the board.. it has 6 x 5503 MOSFETs on the board which are all rated 50-80A continuous each depending on temp.. so how do you get from 6 x 50A mosfets and say “25A esc”?

Pic related got me curious, I was gonna replace my brushless truck ESC with one that can do higher voltage. And I thought since it’s the stock cheap one I could open it up and solder on mosfets that can do higher voltage with a heat gun.

All I need is a high voltage but not high current esc, and it seems easy to get single plane/multi rotor escs for that but not car escs.

>>1994317
>so how do you get from 6 x 50A mosfets and say “25A esc”?

You need 6 to form a 3-phase H-bridge, only two of them are conducting at a given time (ignoring synchronous rectification schemes). Further de-rating comes from the fact that MOSFET ratings are basically bullshit and barely get you into the ballpark. As a quick example, going to DigiKey and filtering for TO-220 packages and sorting by continuous current turns up this:

https://www.littelfuse.com/~/media/electronics/datasheets/discrete_mosfets/littelfuse_discrete_mosfets_n-channel_trench_gate_ixt_340n04t4_datasheet.pdf.pdf

...which claims it's good for 340A, despite the fact that TO-220 leads start to melt around 150A. It even lists the "lead current limit" as 160A.


Your limiting factors are really the RDSon rating and how well you can dump heat out of your assembly. The first one is easy to check, as it's a critical spec listed prominently in the datasheets and search tables. The second is much more difficult, and the most honest way to do it is to test it experimentally.

Tl;dr: You "get from 6 x 50A mosfets and say '25A esc'" from determining that 25A is a reasonable rating to keep temperatures under control.

I'm adding lights and FPV to my RC. My FPV has connector for the battery balance charger.

Is it possible to hook it into the RX and power it that way instead?

I'm looking to be able to turn it on and off without physically unplugging it from the battery each time.

I'd also like to be able to turn the lights on and off with a switch on my controller. Would this be set up as a special function in OpenTX?

I know there are videos/ tutorials out there for this type of stuff - I just need some general direction on where to get started.

Thanks!

It looks nice but I still doubt the target audience is really.. Out there for this

My cheap RC truck has a small esc and 2845 3000kv ish brushless motor, 10.77 ratio, and 112mm tyres. Going to replace ESC and motor.

I was thinking of originally the 3650 6900kv motor and going for like a 15:1-17:1 gear ratio. But I could also just drop in a 3650 3600kv or 4500kv without worrying about that.

>>1994272
No, I want the battery that is connected to the goggles to stay connected and just charge the battery by plugging a USB-C cable in.

>>1993163
SERIOUS QUESTION - Why would anyone build their own drone, especially like the one in this pic? Surely it's not cost effective? Not to be a shill but DJI offers a Mini 2 that both shoots video and takes pictures in 4K, you can actually rotate the gimble up and down to see where you're going and using your phone as the screen, not just put some GoPro on it and have to check the feed when you get back. There's also GPS to keep it steady, a return to home feature if the signal is lost, you can fly for miles out with over 30 mins of flight time, etc. All that for only $450. Heck building your own the cheapest GoPro is gonna run you $200 and you haven't even started building anything yet. There's no way building your own drone is gonna get you all that for anything less than that price, so why bother building one? It seems like people are keen to waste time and mostly money creating an inferior drone when they can just buy one for less and start flying. What am I missing?

>>1994428
If the DJI mavic is a wheelchair, the quad in OPs picture is a skateboard.

Sure they both have 4 wheels and roll, but one of them allows you to do crazy stunts and tricks, while the other one is mainly for disabled people.

>>1993691
I wonder if a software update will force this on all existing drones. My brother had a DJI Spark and claims he was able to go up to 16,000 feet / 4,800 meters in the air. But they forced an update on the drone, and now it can only do the 1,640 feet / 500 meters. I know Drone Hacks can bypass all that for the Spark but still... Hoping they come up with a bypass for the Mavic Mini soon. I really wanna get up in the clouds and no I don't care about the police or anything. I'll just keep an eye out for jets and if I see one I'll come back down. My mavic mini is over 250 grams now with some accessories and I never bothered to register it because who really cares unless your using it to run a business. Cops don't know the laws on this stuff anyway

>>1994434
I can guarantee you that for the price you'll pay to build one of those, you could have bought a DJI drone ready to fly that can accomplish the same thing in Sport mode, has way more safety features incase of a real world accident so you don't loose the drone, and look cooler doing it

>>1994445
Nigga you can't even power loop a mavic.

Go watch some FPV videos on youtube and then come back.

>>1994442
Thanks for the reply anon. I currently use a mini 2 and maybe its my age (41) but I can't see the damn thing past 400 feet. With the firehouse strobe on the bottom its easier but still that doesn't solve the LOS issue with being in control of your drone. A strobe shows no direction. Obviously you can look down at your phone and have all that info at your fingertips. I live in the mountains and get great views at the top of low clouds below 400 feet. This was New years day when we had low clouds

>>1993390
>all that money and weight
>still using analog video

>>1994428
You're trying to compare two completely different things; the quad in the OP picture isn't trying to replicate anything that a Mavic does, but instead does something very different.

Vidrelated simply isn't possible with a Mavic. Gimbal stabilised subject-tracking follow-me shots aren't possible with a FPV quad. They each have their own, quite different, purposes.

>>1994471
Easily upgraded once I get around to it.
I'm holding out for the V2 at the moment.

>>1994428
>What am I missing?

A lot. You've clearly never flown.

>>1994475
>tfw the only difference is that v2 is compatible with their new freestyle drone which no one wants

>>1994478
Fairly sure V1 already is going to be compatible.

And even if that turns out to be the case, I'd rather wait the couple months than buy a $800 piece of kit that's obsolete in half a year.

The risk-reward seems to be in favor of waiting. And it's not like analog is straight unusable.

>>1994376
I still say it all depends upon how it actually works. If it makes acro flying accessible to normies via an idiot-proof training mode like the Connex Falcore had, I could see it being a commercial success. The Falcore was actually pretty neat, but they just didn't have the brand recognition or momentum to succeed.

>>1994461
That's a pretty cool picture you got there thanks for sharing. I don't bother with the line of sight thing personally. I just shoot straight up from my driveway and take off. I look at my phone screen the whole time to see where I'm going and record video of all the cool stuff I can see. I fly as far as I want, and when it looses signal my mavic mini comes back to me. That's why I bought it really. You get to explore stuff and get cool footage and not risk loosing the thing. I usually stay at about 250 feet and can go out about a half mile before loosing signal. Only flying line of sight is really gonna limit the capabilities of the awesome videos you could otherwise be shooting. Trust your phone screen and trust the return to home anon. And keep it in sport mode so it has a fighting chance against the high altitude winds.

>>1994550
>I don't bother with line of sight
>I just fly until the connection drops

This is incredibly fucking stupid. It's morons like you that drive so many of the restrictions that are being introduced.

>>1994473
Thanks anon that video gave me motion sickness

>>1994567
You must not fly FPV then. It did nothing for me.
You get used to this very quickly.

>>1994554
This is 100% wrong. It's the people who want to go up high that are driving the restrictions. No corporation wants to risk loosing their $100,000,000 commercial jet to a $400 drone. So they are pushing the FAA to make rules. No one gives a shit about any flight under 500 feet / 150 meters where no airplanes are. The general rule is below 500 feet is for unmanned aircrafts and above 500 feet is reserved for manned aircraft. To anyone with half a brain anything under 500 feet is fair game, do whatever you want no one cares. Just don't go up high and risk taking down a real plane

>>1994550
>I don't bother with the line of sight thing personally.

right, but thats one of the reasons for the new regs, they (anyone) will be able to see your remote and the drone so it will be much easier to know who is flying three miles out.

>>1994571
>above 500 feet is reserved for manned aircraft
I live out in the woods but three miles from my house is a small airport that does skydiving and mostly ultralight stuff. The one issue though, is there is a med·e·vac station there, I have to be careful even flying at 400 feet, the helicopters they use is very quiet until they are right over your head at 120mph

I don't really know much about electronics or flight but do you think it would it be difficult to canibalise this shitty drone and make a plane with the parts?
it would have two propeller under each wing

>>1994582
Line of sight is not a specific term and is going to vary from person to person. Some people have 20/10 vision, some people have 20/20, some have 20/100. There's no way to prove I can't see the drone, I'll just say my eyesight is better than most and I can see it just fine. It's not like you're flying blind anyway, you literally have a camera on the drone and you can see everything on your screen. People act like you're shooting out 3 miles blind lol

>>1994608
yes but even if you have perfect vision, no one is able to see 5000 feet out with a drone the size of a small tablet.

>>1994554
>>1994571
Restrictions are based because it keeps normies, casuals, and eurocucks out of the airspace that I'm gonna fly in whether or not it's restricted.

>>1994623
I can, and you can't prove otherwise

>>1994702
correct I cant as you're just an anon talking through the interwebs. but law enforcement can easily prove that you can't.

>>1994645
If I have to keep my eyes open when I'm flying then so do you. It's not up to me to fully avoid crashing into something. You should be focused at all times when flying and be prepared to take evasive maneuvers if necessary. That's why ALL driving is considered defensive driving. Not aggressive driving, defensive driving. Play defense, remember you're on a team, and get where you need to go. I'm flying and so are you and that's fine, let's just keep an eye out for each other and everything will be fine.

>>1994608
The line of sight rule is to guarantee you can safely pilot the drone back/land. Video transmissions on drones are not reliable enough to use solely for navigation.

There are other ways to follow the rule though- use a spotter with binocs and a radio to you

>>1994704
No they can't, they are civil servants not optometrists. They have no medical degree period to make any lawful distinction of the medical capabilities of someone's eyesight. The most they can do is tell you to leave. Just say yes sir, pack up, and move on. They really don't care. When cops approach me I usually just let them fly a mile or so out at about 1,000 feet up so they don't wreck it. They always say it's cool but they still have to ask me to leave which I'm happy to do. I've never met a single cop who knows anything about drone law lol

>>1994718
well then I hope you're not the one that ends up fucking up and we end up getting non adjustable distancing.

>>1994710
I really hope you guys are trolling. Fly your drones however you want whenever you want, and if someone complains and asks you to leave or tells you that you can't fly here, just pack it up and move on. 90% of the awesome drone YouTube videos have people breaking the law to get the shot. Flying too high, flying out of sight, etc. If I'm on a sailboat and I video a 360 around the boat and the drone goes behind the sail for a second so I can't see it, isn't that breaking the law because it's out of my sight? How else are you supposed to get that shot? I mean honestly... I hope you guys are trolling

>>1994721

SO LONG VIRGINS

>>1993607
This thread is for discussing things we give a shit about.

>>1994445
No, a Mavic cannot do what the quad in OP could do, even if the Mavic was in sport mode. They each have entirely different purposes.

>>1994729
Make sure to crank your VTX up really high so the second you plug in your drone you're breaking more laws.

>>1994445
>I can guarantee you
lol, fuck off

>>1994732

Can someone point me in the direction of how to turn a RX channel "on/off" so I can remove power to the camera or lights with a switch?

>>1994747
Jokes on you pal, I don't even have VTX

Betamax users rise up

>>1994718
>>1994724
I'm glad that works for you. But this is what it sounds like to me:

When I was at a weapon display in west virginia, they were firing vintage automatic weapons and a loud fucking anti-tank cannon of some sort. Round went through 2 inches of steel plate. Eventually the cops came out, and the group let em take a spin on a few things, cops smiled and left. Didn't hurt that 80% of the people there were ex-law enforcement / FBI / CIA.

So my advice to people shooting guns is just shoot whatever you want whenever you want. If someone complains just move. I just let the cops take a few shots and they won't ever bother you.

>>1994769

I'll be sure to hand the officer my Radio next time I get checked on.

>>1994777
I'm sticking to the most basic rules.

Also I'm not from a police state, nor from a loicence-state.
They want to see insurance and a name-plaque, that's about it.

Can anyone help me figure out why my new 3" drifts hard to the back left when in angle/horizon mode, even after Ive calibrated and tested the accelerometer a couple dozen times? Its a 3 incher running 1204 motors and an iFlight succex micro stack. Ive tried everything short of flashing the firmware and Im attempting to do that right now.

>>1994761
That's not how RX channels work. They output pulses, usually between about 1000uS at the low end to 2000uS at the top end. If you want to switch power to something, you will need some sort of circuit that can interpret that signal & then trigger a relay/MOSFET/whatever to actually control the power.

Very good information comes from this man. Very interesting stories / build logs, too. I hope CJ keeps posting here. I love his tidbits.

How do you all feel about having a threadly / weekly challenge? For example, the first challenge could be something like: Do a powerloop through something cool. Then you post the /short/ WEBM here, and others will do the same. Then get more specific as time goes on, e.g. orbit a sculpture near you, or catch a glimpse of a wild animal while flying.
Share you thoughts, please. I think it might stir up some excellent OC.

>>1994821
Ok thanks. I assumed that the RX could enable or disable the power on it's own channel.

>>1994850
>>1994821
Perfect thanks. What values would I use for the switches to indicate an on state?

I could use some help getting my FPV cameras going.

I currently have a fatshark camera/transmitter that connects directly to the battery.

I am putting together a second system, and I'd like it to connect to the RX power. I picked up a foxeer predator, and now I need a transmitter.

It looks to me that the transmitter gets powered by the small plug. Do I get an adapter and plug that into the RX to power it?

Do the 4 outgoing lines also provide power to the camera?

The camera has a second plug for OSD. Is _that_ where the red and black plug from the transmitter goes? If so, how do I power the transmitter?

>>1995189
Forgot to ask if people have recommendations for transmitters. I'M looking at

>>1995165
Threadly could work. I don't know about where you live, but here in winter it can literally be weeks between suitable conditions to actually get out to fly.

>>1995183
>I assumed that the RX could enable or disable the power on it's own channel.

No, 5V & GND are common across all the channels.

>What values would I use for the switches to indicate an on state?

Depends on the circuit. Most will probably assume anything <1500uS is one state & anything >1500uS is the other state.

>>1995189
>I'd like it to connect to the RX power

Can you elaborate? The receiver usually gets fed 5V from another source (flight controller, BEC in ESC, etc.). Unless your VTX runs from 5V & you know that the source of that 5V is actually capable of supplying several amps you're not going to want to power the VTX from there.

>Do the 4 outgoing lines also provide power to the camera?

Usually there are 3 lines that go to the camera, for 5V, GND & video. The 4th line is probably for controlling band/channel/power from the flight controller (if you have one).

>The camera has a second plug for OSD

That is where the little joystick/button pad that comes with the camera attaches temporarily so you can configure the camera's built-in OSD, which can be useful if you're not using a flight controller with a proper OSD.

>>1995191
Both of these take direct battery input, eg not 5V from the receiver. These are entry level VTX, most people would recommend spending at least a little bit more, maybe look at some AKK brand VTX?

>>1995207
Thanks so much. I’ll look at the higher end vtx. If I can’t power it off the Rx im back to trying to figure out how to turn it on and off remotely. It’s not a critical issue but seems like something that should be easy to do.

>>1995276
These days the focus is more on 'intelligent' control of VTX from a flight controller (via that 4th wire). The flight controller can toggle band/channel, but also toggle the power level - including the very low power (~0.1mW) 'pit mode' that many VTX are now including.

This is great for multirotors, but obviously useless for anything that doesn't have a flight controller, like a simple plane or a car.

Is it just heat build up while on the ground that you're worried about? Or is it about something else?

Can anyone possibly link me to a cable I can use to power my lipo charger from my cars cigarette lighter? The charger uses a C5 connection but I can't seem to find a C5 cable that plugs into the automotive jack by just googling it, figured someone around here may know what to search.

>>1995439
You mean C5 like picrelated? That's a 120/240V AC mains connector. Your car's lighter socket is 12V DC.

>>1995439
Your charger has an integrated AC/DC converter, then. See if you can find something labelled "DC input" or similar on your charger.

Or just tell us the exact make and model of the charger

>>1995290
Just draining the battery if the car gets turned off, but battery isn't unplugged. Also I've got 8 channels on this thing, so might as well do something with them :)

It's not anything critical.

Thanks for explaining pit mode, that makes sense to me and I see that as a feature on some of these VTX.

>>1993163
Just went up to 1,600 feet/500 meters, and I'm right on the edge of 5 miles away from an Air Force base.

So I got a Taranis, but never really bothered to put a mod in the back, should I buy something specifically?

In that case I'm fine
Thanks matey

>>1993163


why are drone enthusiasts so fucking gay?

>>1996345
Makes sense. Planes only need to run one propeller and drone need to run 4, so 4 times the power draw. Plus you can always slow down a plane and glide. No such luck with a drone. You ever mess around with the lift capacity and see how much you can carry?

>>1993163
Anybody ever use range extenders on their controllers? I just picked one up and I plan to use it this weekend. Wondering what kind of performance I can expect, anyone have some first-hand experience?

>>1997710
Planes produce lift elegantly by the forward motion of an aerofoil, multirotors produce lift by literally just pissing power downwards. A plane needs substantially less than 1/4 the power of a quad to fly the same weight at the same speed.

>>1997711
Honestly they make very little difference. Just learning to orient your antennas correctly, repositioning throughout flight as necessary will make 99% of the difference.

>>1997710
I've done rough calculations based on motor and battery amperage for some other planes. I have a 1.2kg plane that has >1kg of thrust, and theoretically could easily carry a .5kg payload and still fly okay because planes need something like a 1:3 thrust to weight ratio (rough, model-specific). Don't really have much interest in that though.

Got a friend into FPV recentlly, told him to buy a Taranis and sim. Hes telling me that Windows no longer supports using your TX with the sims. Is that true, is there a way to still do it?

>>1998377
Your friend is incorrect. They probably just have the Taranis in mass storage mode, rather than HUD joystick mode.

>>1998377
Taranis has a joystick mode
He needs to flash the correct firmware

Are slim goggles fine if you have uneven eyesight. One eye is perfect, and the other is mildly blurry at all distances (from keratoconus). Will box goggles be better?

>>1998655
Imo spare yourself the hassle, if you got glasses just get Cobra X box goggles they're the best on the market at the moment for its price of <200. Hell even people who don't like box goggles think they're pretty damn good
Alternatively you can get the DJI goggles if you're willing to pay much, much more

>>1993163
some of the parts in Joshua diy noob guide got discontinued

Just used my range extenders and yeah they help a little. It wasn't much maybe an extra 400 feet or so, but it was further than I've been so that's nice. I was about 3,000 ft / 900 meters from my house WAY out of line of sight and a USAF C-130 was coming back to the air force base to land. How screwed am I? You think they'll track me?

>>1999024
Might as well enjoy it before they catch me. Just climbed on my roof and yeeted over a mile out to this water tower

>>1999070
Anybody know what this stuff is on top?

>>1999071
Might as well go all in. Yeeted over a busy intersection. Spoiler alert, nothing happened. Kept it in Sport mode for high wind safety and made it back home with over 35% battery left even after going out a mile and playing around. No need to worry about all the red tape people, just enjoy your flights. Mavic mini ftw :)

>>1999073
Another one I took a while back. This is maxed out at 1,640 feet/500 meters and shows a full 100 acres of farmland. My drone is over 249g with a CPL lens filter and I never got it registered. I also don't have my drone pilots license and I don't intend to get one. Just have fun people, don't worry about all the stupid regulations

>>1999085
Looks like fun, bro!

>>1999071
Couple point to point microwave dishes, and then some wider angle radio things. Probably leased the top space to cell phone carriers

You'll be fine, just stay away from the runway and the base in general.

What does messing around with a Mavic Mini have to do with /diy/ ?

>>1993163
Let me know if there's a better battery place.
Got a 12v toy, looking to upgrade the battery from 4.5amps.
Battery tray has cut outs for 5.5"x4" and 6"x3", but I can't find any battery that fits that profile. Most common I could find is 5.9"x2.5".
Current battery is a Toyo 6FM4.5
>3.54 x 2.76 x 3.98 inches

>>1999800
HobbyKing are pretty useless for everything except batteries, so they're worth a look. They have a larger selection than anywhere else that I know of & even let you search according to dimensions.

>>1999447
Where else will you post about RC? Also there often comes a time when these mavic ppl get tired of extreme hovering and want to get into FPV like the rest of us

I'm looking for a drone for a very basic workload, for cheap:
>go straight the fuck up a hundred or so feet
>live feed from camera
>turn a bit to look around
Basically something I can survey the area around me with. No fancy flying, extended flights, or sweeping cinematic stuff, just a live video feed to me. I don't have a smartphone, just an old tablet (teclast x80 plus) with 802.11b/g/n, which I'm guessing is to fucking old.
Is there anything that'd work with my old chingchong tablet, or am I being a tard?

>>1999927
Pic related is the absolute cheapest setup i put together for kids to fly fpv without worrying about them smashing the fuck out of something expensive.

Just buy the cheapest possible toy whoop clone, install a cheap micro aio camera, extend the sticks on the small radio and buy either some cheap box goggles or a 5.8 ghz dongle you can plug into your tablet if you are looking to dvr the footage. I used an eachine e011 there, they seem to have discontinued that one, tho you can do it with any small toy drone, my first drone was a hubsan x4 and i carved an enclosure out of wood for the camera. This will do the things you mentioned wanting to do at the cheapest possible price, but you'll soon want to build a real drone if you do it

>>1999860
>let you search according to dimensions.
That should get me in the ballpark.
Many thanks.

Disregard drone laws, fly what you want.

>>1999999

>>1999975
Top fucking post, man, that's pointed me in the right direction.
>5.8 Ghz dongle
Fuck, I didn't even think about that. My tablet is a dual-boot, I've got access to android and windows, so software/driver compatibility shouldn't be a problem.
>but you'll soon want to build a real drone if you do it
Oh, I've been wanting to get into drone stuff as a hobby for a few years now, so hell yeah, but right now I really just need a "local surveyor", and the general setup you posted sounds like it'll fit the bill.
Good shit.

>>2000043
This is the one i have, i used it to dvr footage with my phone until i got my fat sharks. Looks like there are diversity receiver dongles now for just a little bit more

Sounds like you'd be way better off with one of the infinite dirt cheap Mavic lookalikes. The kinda thing that has a decent resolution camera that broadcasts over WiFi, rather than a shitty analogue FPV camera. A Whoop is also going to get lost very easily when you try to fly it 100ft up & there's even the slightest bit of wind.

>>1999999
Wow. Checked with nothing but truth.

>>2000369
I agree. Whoop would be very fun but is too easily jostled by a light breeze.

Hi I just downloaded RealFlight 7.5 with serial keys, but I can't install it because it doesn't see my transmitter. ClearView does see my transmitter. Do I need different drivers? or a crack to bypass this?

>>2000589
Just get Liftoff for Steam

>>2000630
RealFlight is fixed wing, not multirotor. At least Google what things are before trying to act smart by recommending completely inappropriate alternatives.

>>1999999
Checked and based.

>>1999999
Well with digits like those I have to. Thanks.

>>2000589
I think realflight 7.5 literally expects you to plug your radio into the controller that comes with it. Its some real boomer shit unfortunately.

>>2000633
Didn't get to act smart, so my bad on that.
However you're still a cunt with that way of responding, so bite me.

Number of years ago I painted the edges of one of my frames because I thought it looked slick. Now that its all beat to shit and faded I dont like it. Is there a way I could remove the paint without delaminating the carbon? Would run of the mill paint thinner work or could that damage the binder for the carbon layers?

>>2001004
Dude you're supposed to fly them, not look at them. Fuck the edges.

>>2001018
hes right anon, nobody gives a fuck if your drone looks nice.

>>2001022
>>2001018
If no one gave a fuck if it looked good no one would make motors that look cool.
Either if you guys happen to know how to get the paint off or what?

>>2001026
Most motors are just black and silver, or they look like 90's beyblades. Nothing cool about that.

Anyways, I suggest you try the paint thinner on a broken or unused part of carbon first. Even though epoxy should be pretty stable generally.

>>2001004
Just use sandpaper.

I want to order some EV300Os to the UK, banggood says there's no delivery options for the China warehouse, only UK warehouse where they're £50 more. Am I getting chinked?

>>2001381
They might just be cutting down on high-value items shipping direct from CN, because of the higher risk for loss/scam. In order for a £300+ pair of goggles to get through customs without landing you an extra 20% VAT + a bullshit £13.50 'handling fee' they have to declare the value on the customs label at <10% of its actual value, which means if the package goes missing they can't claim more than £30 from the shipping company.

Genius. Any of those that work on frsky qx7? I'd search myself but I don't really understand what makes these actually work.

>>2002796
it works on any radio that has ppm out, it worked on my old taranis and turnigy 9x, so it will work on your qx7. You just plug in the 3.5mm port in the back and you're golden.

>>1993569
Quad: Mobula 6 HD or eachine trashcan/tinyhawk 2 if you also want to be able to fly in a bigger space.
Radio: Flysky fs-i6x but if you plan to go any further into rc, most likely you'll eventually want to upgrade. Jumper t-lite seems good and is cheap but I don't know much about it.
Goggles: Eachine ev800d

Just like in audio we can disregard any retards who say they can hear past 20kHz, we can also disregard your stupid claims

I've had a few cheap wifi drones and the video just goes to shit as soon as you go past 20m, not recommended at all.

>>2004114
Most children can actually hear past 20KHz. About 25 years ago I could hear to 27KHz (tested by an actual medical audiologist). Ofc today I probably can't hear past 17KHz.

>>1997711
range extenders don't really do anything unless your controller is really shit.
Even before I moved on to CRSF protocol my stock FrSky antenna was going fine, and even at 800mW on my TBS Unify I'd loose video before I lost telemetry.

so don't use range extenders. not only do they make you look retarded, but they might actually hamper you if you go anywhere besides right infront of you (boring).
Just buy a crossfire module if you're having range / latency issues. But don't buy into the DJI shit. Only assholes do that. Fuck DJI.

I did the battery mod to my eachine ev800d goggles (pic from internet). However, because liions have less voltage, the meter is off. Could I throw a 3s liion in there without issue? I know the standard external power option can take a 3s but I don't know about the circuitry for the normal internal 2s battery.

>>2006094
so lemme get this straight
>your EV800Ds can take 3S as standard external power intake
>you want to swap the internal battery with a 3S

if that's the case I recommend you dont do that. why would you? Internal batteries are fucking retarded. Keeping things external means you can quick-swap batteries (and even hotswap with appropriate cabling), and also use the capacity that you want (meaning huge batteries that last for hours).

Don't be gay.

>>2006103
Using the external cable doesn't give you the battery status. The 800d battery mod is to route wires to the back of your head so they are external but still using the internal connections so you get battery status.

Don't be a nigger and talk about things you don't know about.

Are today's flight controllers and ESCs advanced enough to let me put 4 different brand motors on a quad and it still run good? If imagine it would run flawless if I put 4 different brand but same size and same kv on there but what would happen if I used different sizes or kvs?

>>1993163
i have a bunch of left over parts, i want to make a tanky trainer-drone with 1000kv motors and 10" props. I want it to be indestructible so i can let people play with it. Maybe some kind of flying box with mesh screens or something...

What do you guys think?

>>2006106
>>2006103
Sorry, didn't mean to be sharp. Newborn has me not sleeping and on edge 24/7

>>2006140
Yes. In fact, the motors don't even need to be the same size/kv. They don't even need the same size props.

>>2006218
Bigger is actually less durable, on account of more moving mass.

>>2006106
You can use external battery monitoring solutions. Passthrough voltage checkers with alarm when leftover charge goes below 10% something like that.

>>2006106
>>2006524
The battery meter in the EV800D (in all of the cheap Eachine goggles/monitors for that matter) is hilariously inaccurate anyway, so I wouldn't worry so much about preserving its functionality.

>>2004114
>>2004716

boom, roasted

>>2006041
Actually those range extenders worked for me, so if someone is looking to buy them I can first hand confirm that they do in fact work and yes I would recommend them. I was able to go further out than without them. The trick is to just point them in the direction you are flying. That was $10 well spent

Any bump, tree root, rock kicks the mower and the cut looks zig-zag.

>>2007381
Just demand a refund or a replacement for the whole thing, make a PayPal claim if you have to. Don't let them mess you around trying to make you repair it yourself.

>>2006919

I'm new to RC, do I really need a £100+ balance charger? Seems like a big outlay for a simple task.

Of course you don't, where are you reading that?

If you're just starting out you can just grab something like the ISDT Q6 Nano (£22.29 on banggood right now, or ~£25 if you can find it in stock in the UK) & pick up an old Xbox 360 power supply for £8-12.

Making others bleed should land you in jail.
Either way, there's no need for loicensing anything.

Maybe there should be licensing to prove you're smart enough to not be retarded and have an IQ above 80. Brown "people" and hispanics need not apply.

>>2007730
When DJI literally promote hand launching/catching their drones as a 'feature', you can't really be surprised when normies think that reaching out to hand catch a drone is safe.

>>2007584
Awww did de wittle bebe get a boo boo? What's next, you poke yourself with a pencil and now everyone has to get pencil licenses? There is literally no reason a drone should ever need a license to fly, that's retarded

>>2007730
Maybe there should be licensing to prove you're smart enough to not be retarded and have an IQ above 80. Racists can take a special test to demonstrate they aren't as retarded as they sound, and can co-exist in modern society.

Iglesias wasn't launching a 250 grams drone, retard.

How do you guys feel about good clones of discontinued frames?

are there any nanoVA alternatives for testing antennas in that price range or lower?
Also did anybody here tryout the orangeRX modules with UltimateLRS? I have them binded and they work, i'm about to test them on ardurover before putting on plane, just curious how reliable they are and what to look out for.

>>2008252
Still pretty expensive thought, right? You're looking at ~$250 minimum in parts, unless I've missed some new release that drastically cut the costs.

>>2008254
Except it isn't just <250g stuff that DJI promotes doing this with. Friend of mine used to hand catch his Mavic Air, because DJI said he could, until he got it ever so slightly wrong and it tore one of his fingernails off.

>>2008347
If the original designer won't either sell it to you, or sell/give you the DXF files to have it cut yourself, I wouldn't feel too bad about buying a clone.

>>2008359
It's still 400 grams, the Inspire that the retard tried to grab was at least 3kg

>>2007520
This is right, do whatever you want, just don’t post it online with commonly used devices or home/work networks, that’s absolutely retarded because we all know that Jannies exist in all forms

>>2008387
In this sort of scenario it's not the weight that matters, it's the spinning blades. Even just the 5" props of a Mavic Air easily sliced up my friend's hand and launched his fingernail into low orbit.

Weight is more of a concern with stuff dropping onto people, cars, etc.

I hand launch wings all the time tho

>>2008612
With most wings it's not even remotely similar to hand catching a quad

Hand launching an FPV quad is one of the stupidest things you can do. Anyone with half a brain understands never to do that. Head launching is the only responsible way to take off.

No more 3D printed brackets to attach landing gear to arms anymore, should've just done this right from the start.

>what is momentum

I know this is 4chan, but you can't really be this stupid?

>>2009013
Well done, you're getting there. Now try to find a correlation between the momentum of the blade and the weight of the drone.
Hint: It has to do with lift.

>>2009017
What are you even talking about? The point I was making is that a 250g drone falling on your head or your car windshield whilst driving along is less of a concern than a heavier drone falling on your head or windshield. Nothing to do with momentum of the blades or the amount of lift.

Heavy stuff falling on you bad. Light stuff falling on you less bad. Is that simple enough for you?

Fucking hell.

>>2009058
A Blackhawk blade would cut trough you like butter, a Eachine E010 one you would hardly feel, even though the second one spins at a higher rate; the reason why has a direct correlation with the weight of the two, if you still can only think about them falling on your head please refer to >>2009002

>>2009065
I honestly don't understand what we're arguing about here.

The bigger a propeller, the more damage it will do if it hits you whilst spinning. Tiny toy quad props probably won't even scratch you, 5" race quad props will slice you up nasty, a paramotor prop will take your arm off.

The heavier a drone, the more damage it will do if it falls on you if it suffers power loss/desync/FC crash/etc.. You'd barely feel a toy quad fall on you, you'd get a decent bump on your head or maybe crash your car if a Phantom fell on you, you'd end up in hospital if a 20kg agricultural crop sprayer fell on you.

Seriously, which exact parts of this are we disagreeing on?

>>2009065
>the reason why has a direct correlation with the weight of the two

Oh fuck me sideways, you thought we were talking about the weight of the fucking props? Not the weight of the drone?

Fucking. Hell.

>>2008913

>>2009068
The momentum of the blades and the weight of the drones, you goddamn retard.

>>2009096
Yes, precisely. This guy >>2009065 is clearly arguing about the momentum of the fucking blades, which literally nobody brought up.

A bit broad topic, but it couldn't hurt: I have an interest in working in logistics/supply chain management. What opportunities are there with drones in that industry? Could I just apply for a pilot license and start my own delivery business, intern at an established drone company, or is there something I'm missing? Commercial use for drones is still a new, but interesting space and idk where to start.

>>2009873
I did commercial drone video & survey/inspection work from 2016 up until covid & have been actively looking for a new job in the sector ever since, so I'm fairly up to speed with the state of things.

From where I stand, it's a very saturated market. The low end of the market for the sort of stuff I did is completely flooded because the initial outlay is so low. The high end of the market is dominated by large established cinema or survey outfits who have decades of experience & portfolios from before drones existed, so is essentially completely unassailable.

For the delivery sector, the problem is mainly one of regulation. You won't be able to operate a drone delivery business under the standard aviation regulations of your country & your aviation authority isn't going to entertain any sort of application for exemptions for a one-man operation, especially when that one-man has zero experience.

Joining an existing company is simply an issue of very few openings & vast numbers of applicants who all have substantially more experience/qualifications than you.

I probably sound quite bitter, but I can't even get an entry level job in the industry right now & that's with years of experience & training/qualifications.

>>2009873
Fuck commercial drone delivery. It's the excuse companies like amazon have used to lobby the government to regulate our hobby out of existence. Have you considered a career in stealing their drones?

>>2009968
>Joining an existing company is simply an issue of very few openings & vast numbers of applicants who all have substantially more experience/qualifications than you.
>can't even get an entry level job in the industry right now & that's with years of experience & training/qualifications.
So, the same issues with nearly every other tech industry but compounded because the space is newer and more highly regulated. Got it. Well, at least I know not to keep my hopes too high

Traffic studies show that traffic flow is most efficient when approx. 30% of the drivers on the road are "aggressive" drivers. Too few means the roads are clogged with legalist grannies, too many means everyone is so much of a dick that the roads turn to chaos. 30% is just right to keep the order of the system with 70% of the people driving the speed limit and keeping safe while aggressive people go ahead on their way aggressively around them. not saying this because I'm in favor of one "side" or the other, I have my sunday cruise moments and my fuck it I'm passing all you faggots moments, just an observation from a 10-20 year old study near the end of the era when govt. studies tended more towards truth and less towards supporting the conclusions of the politician that funded it. /end off topic rant

>>2011013
Pretty sure 'efficient' doesn't correlate with 'safe' on that study.

>>2011021
oh, have you read it?

>>2011027
Common sense.

anyone has experience with frames from aliexpress?

hi

>>2011811
I've never ordered a frame from aliexpress but all of the frames I use are Chinese knockoffs of premium name frames. I've had zero issues with any of them, save for the occasional poorly aligned holes to attach arms or whatnot. I personally see no point in paying $100 for a big name frame like Drib or Ummagawd when I can buy 3 of the clones for the same price and use the other 2 as spare parts.

>>2011996
hullo

>>2007584
what kind of dumb fuck sticks his hands into fast moving blades.

>>2012110
There's more of this type of idiot than you may expect.

Haven't been able to go out & fly in months, but I'm itching for a project to work on anyway, so I'm going to start on a new frame design. Probably 3mm carbon for the bottom two plates, then I figured I'd try aluminium box section for the arms this time, instead of roll-wrapped carbon (that was really pricey last time).

>>2011996
FYI the stock motor/ESC are garbage, in case you bought the PNP version & weren't already planning on replacing them.

Is there a guide on PID tuning for larger quads?
Ive been wanting to try building a budget XClass for awhile, just a project and something to fuck around with. But Ive heard passed like 7 inch the default PIDS for betaflight are pretty shit. So where would you even start with something running like 13+ inch props?

I've flown pre-built mini quads and am wanting to get into building my own from here on out. I'm currently seeing the Flysky fs-i6 for 50 bucks on banggood, should I get that or some other transmitter?

>>2012294
The tuning process is the same regardless of size. If you understand the fundamentals of what the different values do, you can apply that to anything.

>>2012332
arguably if you're gonna spend $50 on a tx, chuck another 10-20 at it and consider the radiomaster t8 pro.

It'll do radiolink, FrSky, Flysky and a few others.
plus it's got the configurability of opentx

>>2012352
alright, that sounds better & looks like it's only $55 at the moment. Thanks for the heads-up.

>>2012396
note that only the pro version comes with the screen, but it also has hall gimbals

>>2012402
oh okay, I see that now. Yeah, it's probably worth the extra $15.

>>2011811
>>2012037
The TBS Source exists. I don't see any reason to buy Chink knock-off frames.

>>2012423
okay, back again for a moment. I was looking into a DIY kit, the Eachine tyro99 210mm, should I go with it or try to keep looking for individual parts? I did start looking at the frames and I think I want to go with a 210 mm frame considering my first pre-built drone is about that size. I'm sure I could probably go for a set of parts that are more expensive, but as I mentioned earlier, I feel I should stick to a budget on the quad for less than $150.

>>2012485
It's safer dealing with commodities.

EU anons, have you yet looked into the new regulations that will go into full effect in 2023?
Seems we'll be required to fit remote ID transmitters.

does blade shape matter much?

>>2012808
There's absolutely zero point whatsoever looking at things that far ahead. The December 2020 regulations were still being altered literal days before they came into force.

>>2012869
Yes, it can make a immense difference.

>>2012900
I guess.
The current version doesn't seem that bad though, especially when you compare it to the Burgerland-proposed system.

>>2012941
Being less retarded than America can hardly be considered an achievement.

>>2012808
I'll never do this if they require it. This hobby is supposed to be care free fun and I'm going to keep it that way. I have three batteries so I can only fly for a little over an hour anyway. And those are separate 25 min intervals. My DJI is already altitude limited and that's good enough

>>2013028
The funny part about your post is that DJI stuff like yours will not only be the first place where these restrictions will be implemented, it's also the place where they'll be hardest to circumvent.

You can't enforce anything on a dumb fixed wing model that is literally just a motor & some servos, but a 'smart' DJI drone linked to a smartphone with a 4G connection is a whole other story.

>>2013039
It makes me so mad that these companies cuck out and make it hard to bypass. If DJI made it so their firmware could be replaced with something open source by "elite hackers" like phone jail breaking. Same with gun companies... Make your design so some "elite cad engineer" can make a 3d printed autosear just plug in there but make it hard enough that fedniggers can't actually do anything about it.

>>2012763
Part it out and see which costs more, the kit or your parts list.

Then compare the specs of the parts. Cheaper parts with a standard name are fine, contrary to what some anons and forums would have you believe.

>>2013048
DJI isn't cucking out, they're actively trying to get the rules to favor them. It's OK to want a flying camera, but don't pretend it's the same as the rest of the hobby. And if you bought a 3D printed drop in auto sear that someone was selling as a "key hook" the ATF knows and they do care. The difference is that the FAA can't enforce shit unless you do something like crash into a building.

Is it still a pain in the dick to get into long range or is it as simple as swapping out my receivers and transmitter?

>>2013264
>they're actively trying to get the rules to favor them
Ah, is this why all the dji shilling is so aggressive on here an r*edit (forgive me, Father, but I need my fix of fpv videos)

>>2013264
I drives me crazy that more people don't get this. DJI wants to set the standard that they mostly already have in place.

>>2012110
You only get bit once. Finally discovered the culprit, my improperly programed throttle on/off switch was actually a throttle 100/-100 switch. Flipped it on and it took off across the room at me. Props stay off in the house now

Seeking some info, maybe yall can help.
I've been into FPV for a few years now, and thought I had a firm grasp on hardware. However I have recently been looking into making a beast class/10 inch, basically just want a big quad that runs 6s. Up until I looked into this venture I always saw people running 6s on 5 inch quads with 1750 to 1900 kv motors. However, looking into motors for a 10 inch I see people running only 900 to 1100 KV, sometimes even on 5s. Is there a reason for this? I was looking at getting some 28xx- motors qith the same kv rating as usual 6s motors. I assumed people run lower KV because they aren't looking for speed.

>>2013815
Damn... luckily I didn't cut my finger with one of those to learn the same lesson, but destroyed a nice suitcase instead, also blew lots of small items and papers all around the office (I never found my brand new 128GB microSD card).

>>2013826
Big props spinning slower are generally more efficient. If you double prop size, you'll quadruple the speed at the tips for the same rpm

>>2013858
Ah, kinds figured that may be the case, ill stick with some lower kv then.
I'm curious if you also may able to tell me a bit about the ESCs I see people using. Half the builds I see for beast class are running 80a individual ESCs, or similar. However the other half are running standard 5 inch 4 in 1s rated for like 55 to 60a. I guess I assumed a 60a 4 in 1 was 60a for all 4 motors, is it actually four 60a put together or 60a for all 4?

>>2013823
You should always have the latest firmware on anything you fly, regardless of what range you're flying. I'm not sure I understand your question?

>>2013868
The rating for a 4in1 is per output.

You mention 10" but then you also mention X Class - these are very different things.

A 10" acro quad (like I'm toying with atm >>2012260) is going to use something like the Xing 2814 which pulls 40A on 4S with the HQ 10" triblade. This is well within the capabilities of a regular 4in1 ESC.

A 15" X Class quad is going to use something like the Xing 4214 which pulls 80-100A. This is way beyond the capabilities of any 4in1.

>>2013874
Why the wood arms? I'm curious

>>2013881
This is just a mock up. Once I'm happy with the design I'll get the plates CNC'd in carbon fibre then cut some aluminium box section for the arms.

>>2013874
Ahh, thank you.
For some reason I always thought 4 in 1s were 60a or whatever to be shared by all 4 motors, not per input. I mentioned X Class because I've juggled the idea of doing either a. Budget X Class or an all out beast class. As of now I think I'm gonna go with the beast class as I want to stick with 6s.
Do you know what motors you are going to go with for that 10 inch? The iflight 2814s are on my list but the Brotherhobby 3115s seem to be very popular for 10 inch.

>>2013920
I'll probably end up going with the 2814. I'm not trying to build a monster, I was actually considering using some 2216 1250kv because I already have 2 spare, but sourcing another 2 is proving difficult. The 3115 would just be added weight for me.

>>2013951
Sweet, should be a fun flyer.
Are you going to use a PDB? Another thing I've noticed in 10 inch build logs are half the builders using PDBs and the other half going with the 4 in 1 as power input.

>>2013957
Probably just use a 4in1. I have a set of individual ESCs spare, but the 4in1 I also have spare is just neater/easier.

>>2013970
Nifty, at this point I was planning similar. Really appreciate all the help, did have 2 more questions though.
First was is there a reason you are going with aluminum box arms instead of having them cut? I was looking at getting a iFlight XL10 for my build, which uses 7.5mm flat arms.
I was also curious about your choice in kv. I was planning on getting motors around 1000kv for 6s, but those xing motors come in 880 or 1100. Is 1100 too much for 6s, or would I be better using 5s on that setup? 880 seemed a tad low, but I suppose I'm not going to be using it as a speed chaser anyways.

why the hell are the goggles so goddamn expensive, theyre at least a 100, the good ones seem to be like 3-500. any good ones for like 50ish?

>>2013980
Give up on your dreams of looking cool and get some chink box goggles with two antenna and a DVR

>>2013975
>First was is there a reason you are going with aluminum box arms instead of having them cut?

I'm going with the same design methodology as my last design (an update to the old Anycopter from Flite Test), where you can use one set of body parts to build any size setup you want simply by swapping out generic materials for the arms (hardwood dowel, alu box section, roll-wrapped carbon rods, etc.) instead of having to get specific different arm sizes cut & shipped from China. Also makes swapping to coaxial or attaching landing gear etc. much easier, because you can just cut/drill with abandon.

>I was looking at getting a iFlight XL10 for my build, which uses 7.5mm flat arms.

The DC10 looks like a much better option than the XL10. I used to have the XL7 & the way the arms attach to the body with the XL frames (they sit on top of the baseplate, rather than below) means that they actually get very cramped inside.

>I was also curious about your choice in kv. I was planning on getting motors around 1000kv for 6s, but those xing motors come in 880 or 1100.

Take a look at the test results on the iFlight page. The 1100kv is intended for 4S 9"/10", the 880kv for 6S 9"/10" (or even 4S 12"). If you try to run 6S 10" on the 1100kv you should expect to cook something, like Gal Kremer did in his thrust tests.

>>2013980
EV800DM is $81 right now. Anything less is false economy, hard as that may be to hear.

>>2013991
>DC10
Would it not be more difficult to get a good tune on because of the weird positions and angle difference of the arms?
I was also under the impression that thrust tests are a decent amount harder on the motors as well? Assuming 10 inch props either way, between 5s on 1100kv and 6s on 880, which would you say I could expect better flight times from?

>>2014006
A deadcat layout doesn't really affect the tune much at all.

If you look at the test results they have power/efficiency data. The 6S 880kv setup looks better, which is what you'd expect - in general higher voltage means higher efficiency.

>>2014010
I guess some part of me is concerned about a lack of power on an 880, though I think with 6s those motors still put out around 3kg of thrust so I'm not sure why.
Keep us updated on your parts selection for that beast, im curious to see which flight controller and ESC you go with.

Alright, newbuilderfag back again. Thoughts on the parts list I came up with here?
https://pastebin.com/WGHfXkbY
I was trying to do something similar to this Eachine kit: https://www.banggood.com/Eachine-Tyro119-250mm-F4-OSD-6-Inch-3-6S-DIY-FPV-Racing-Drone-PNP-w-or-Caddx-Turbo-F2-1200TVL-Camera-p-1584996.html?rmmds=detail-left-hotproducts&cur_warehouse=CN
I have a feeling I will probably want a bigger camera, but let me know if I should change that to something else around the same price and / or something else. I was trying to make something freestyle / longer flight time than one of those prebuilt drones.

Installed some landing lights so I can finally fly past dark.
Anyone have experience launching and landing on snow? I think the wheel pods will be fine on the snow but I'm guessing I need a skid for the back?

>>2014216
you're better off swapping the mains for skis since that's where most of the weight will sit.

>>2014224

>>2014212
>ZMR250 250mm

Lol no. That would've been an alright choice 5 years ago, but not in 2021.

>9g 30.5x30.5mm omnibus f4 FC AIO $20.99
>Holybro Tekko32 35A ESC $24.15

Just buy a F4 Mamba stack.

>4 x Racerstar Racing Eddition 2205 2300KV Brushless Motor $27.99

Again, an alright choice 5 years ago, but not today. Get the Emax Eco II instead.

>10 pairs LDARC 5040 5x4 5 inch 2-Blade Propeller $5.09

Again, 5 year old stuff. Grab some modern triblade props. Which ones you want is largely down to preference, but any of the recent options from DAL (like the Nepal) or HQ (V1S range) will be a good start.

>Frsky XM+ Micro D16 SBUS Receiver $13.99

First thing on your list that's actually sensible.

>Caddx Turbo EOS2 1200TVL Mini FPV Camera $15.99

No experience with this myself, I tend to avoid the super high TVL options (you often can't tell the difference & it just adds latency). The Ratel is my go-to these days.

>NameLess RC Nano400 VTX $16.99

Get something from a recognised brand. AKK is a good cheap option.

>ZOP POWER 14.8V 1500mAH 100C 4S Lipo Battery w/ XT60 Plug $21.99

Avoid batteries on banggood/ali/etc. They come with very mixed reviews & will often screw over/delay the shipment because of regulations on shipping lipo batteries. If you tell us what country you live in we should be able to give you better options.

Also, if this is your first build & you don't already have batteries, it really doesn't make sense to buy 4S gear. Everything is moving to 6S now, so if you're starting fresh you should just go 6S. The Mamba stack handles 6S & the Eco motors are available in 6S kv.

>RJX HOBBY Magic Tape Tie Down Strap $1.51

Bear in mind that battery straps do eventually wear out/tear, so best to grab a multi pack.

>>2013815
>wooden propeller

Wew lad good thing that didn't hit your face

>>2014256
That should work, tons of videos of people flying floats off snow.

>>2014622
Would wood do any more or less damage than polycarbonate, carbon fibre, metal, etc.? If anything I'd imagine wooden props don't have as sharp edges or tips?

>>2014658
He's probably thinking about splinters, I bet they get pretty nasty when damaged. The one that sliced me up was actually carbon fiber and razer sharp. The tip of the prop caught my thumb then the plane fell and the motor shaft snapped on my knee, just about dislocating it

>>2014826
Fuck splinters, I haven't gotten a single one working with wood over the past few months, but every time I work with carbon fibre I get at least one of those fuckers stuck in me.

>>2006037
Speaking of this.
I own a dji mavic mini, and since its under 250g I don't need to register it, but I am hearing that you have to now??

Another question, is there a way I can fly the mini, and not have dji keep tabs on me or law enforcement?

I saw this wiki here https://dji.retroroms.info/ and it seems its possible, I figured I'll ask here while I browse around in the wiki.

Is there a way to get long range on a spektrum setup or am I SoL unless I switch to OpenTX?

>>2014516
Okay, does this look better?
https://pastebin.com/ZrSR9uQp
Also I'm in the US, so if the stuff from china isn't good enough, let me know what battery should work for it and perhaps another drone down the line. I was thinking of something along the lines of 1300-1500 mAh.

>>2015074
If you're running 6s batteries thats good.
I would, and already have, check out the iFlight Cyber Cincinnati 2306.5 2550 kv motors on Amazon. For whatever reason iflight is selling a 4 pack of $25 motors for $67.

>>2015075
Cyber Xing*
Phone somehow corrected xing to Cincinnati?

>>2015008
in the US you don't register the drone if you're not flying commercially, you register as a pilot, but fuck the FAA. Registration is nothing but a way to harass pilots.

I guess it's about time to make a new thread.

>>2015008
There are always going to be 'hacked firmwares' that attempt to circumvent this sort of stuff, but it's a lot easier to just follow the basic rule of 'don't be a dick' so you don't have to worry about law enforcement in the first place.

>>2015172
Not even close, this thread isn't even 2/3rds down the catalogue yet.

>>2015284
You are an absolute retard.

>>2015290
Pretty convincing argument, well done.

>>2015299
It's not an argument, but a statement.
You claim that following the arbitrary restrictions that are set for dumbfucks like you have anything to do with not being a dick.
Stupid fucking cuck.

Noob question. I'm building an foamboard rc plane to keep busy until DJI goggles go on sale. With no flight controller or fpv setup, how do I avoid overdraining a battery. Will it just fall out of the sky?

>>2015337
Protip - you are actually one of these 'dumbfucks' yourself.

>>2015364
If you drain a lipo so much the plane falls out the sky, you will have irreparably fucked that battery. Easiest solution is to plug a battery beeper into the balance connector and occasionally fly past yourself close enough to hear it. Depending what radio you have, you can also get battery meters that send the voltage back to your radio over the telemetry connection.

>>2015375
No, luckily I have common sense and don't do retarded things like flying over people or near airports, but I may go way beyond 120 or 500m of height if I'm in the middle of nowhere, with strong signal and not flying a Leviathan.
Mouthbreathers like you may need daddy FAA to tell you whether or not you can fly your flying dolly how you wanted to.

>>2015284
>implying law enforcement won't bother you if you are following the rules
Unless you're some methed-out hobo with your stolen cart behind you, piggers know you're a nice subject who they can flex their GED-insecurities on because you'll comply because you actually have a life they could ruin if you don't. All it takes is one Cali/bong-implant mom to whine about you spying on her 300lb self even though you're flying at an RC Airfield to have IRL jannies come handcuff you until they're bored.

>>2015464
Not all law enforcement around the world is as utterly broken as yours is in the US. In most civilised countries police don't handcuff people for flying at a fucking RC airfield, in the same way that they don't gun down innocent people for being black. But hey, America!

>>2015519

Holy, cringe, dude, you're embarrassing the rest of the world.

Can we stop pointlessly shitposting about rules and get back to when /rcg/ was actually good?

Let's talk about batteries. Is there anything better than INR21700-30T or VTC6A when making LiIon packs?

>>2015671
>3000mah
Might as well go with some 18650s for that capacity. You can get reliable 21700s with 5000mah.

>>2015739
the 5Ah ones are only rates for like 5-10A of draw my dude

>>2015752
Most 21700s have a decent C rating. At even a 5C rating, which is mediocre for even 18650s, you're still getting a 25A draw. 3C, which would be dogshit, is still 12A.

I'm aiming for ~1kW safe continuous discharge capability in a 4S pack, which means just shy of 70A (67.6A to be precise) at nominal voltage. Ideally I want something 6000-8000mAh. The INR21700-30T seems like the ideal candidate because it's a proven 35A 3000mAh cell, so a 4S2P pack is 6000mAh with 70A continuous discharge.

No 18650 I've found has high enough discharge. Both the INR18650-30Q & the VTC6 are only 15A, so a 4S2P pack is completely unviable (30A or 444W) & even a 4S3P pack is too low (45A or 666W).

For 21700 the INR21700-40T & the VTC6 are both 4000mAh, but they're 30A not 35A. Given the choice between 6000mAh 70A vs 8000mAh 60A, I'd go for the former for my application.

Unless I've completely overlooked an entire manufacturer or something, the INR21700-30T is the winner for me?

Okay, not using the 2216 because getting another two matching ones is too hard. Sold them along with the ESCs I used with them in fixed wings for £50 & I'll put that toward a set of something else.

Just seen that BrotherHobby are releasing a new 2810 & 2812 which might be more suited to what I want. I reckon 2814 (the iFlight) is probably a bit overkill for me & something like a 2810 would be a nice weight saving. Can't find any reviews/thrust stand tests at all yet though, but it'll be weeks/months before I even have the carbon so I'm in no rush.
