/diy/ - Do It Yourself

>>2577291
Honestly I don't see a competitor to the CRSF protocols (Crossfire/Tracer and ELRS). I really like my 915mhz penetration, but I think I'm going to go with 2.4ghz ELRS for my racing and maybe freestyle builds, and just keeping crossfire on my long range quads.
FrSky doesn't even factor into my considerations, the only others that I MIGHT consider trying would be Ghost or Tracer, but there isn't much point to that when ELRS does everyting that they do plus is being adopted to be as standard as Betaflight.

Ok I give up. What goggles should u buy for my first fpv?

>>2577382
It all comes down to how much you are willing to spend, but here's a decent breakdown of what's good at what price point. Personally, I think the DJI Goggles V2 are the best value now that the price has come down from the new goggles being released, and you can even use them with the new Air Unit.
Most decent analog goggles are a bit overpriced still even with digital being better, considering what you get.

>>2577384
Isn’t dji starting to do some sketchy shit like over-the-top geoblocking and requiring registration to operate the drone? Does none of that apply to the goggles themselves?

>>2577395
No, that's only if you are flying their overpriced Avata shitbox, the goggles and O3 AU are fully non-cucked. That's not to say that the next generation of DJI stuff won't get clamped down, so get this shit before a bunch of DC geriatrics decide you're having a little too much fun (happens with anything that lets you free your mind, see: psychedelics, crypto, vaping, guns, gasoline vehicles).
Pre-droneban quads (and 3d printers) will be like grandfathered full-autos, so I'd suggest stacking as much as you can while you can.

>>2577304
Why are you making a new thread? You can easily get 1000 replies before 404, that other thread will be there for months to come

>>2577402
Man am I glad I live in a 3rd world shithole where everything is a bribe away from being fully legal

>>2577324
Then explain, why can't you put $300 125cc scooter engine on a plane and use 1.5kW servos for $30?

I want to have a large RC car to drive that needs to carry some heavy weight (10-15 kgs) but not go very fast.

Option A is take one of these ride-on toys and convert it to remote-control

Option B is to buy a large RC car.

But why are RC cars so much more expensive than ride-on cars? The RC I thought was most appropriate, the Axial 1/6 SCX6 is around 1,200 USD in my country which blew me away.

>>2577591
What are you smuggling, anon?

I thought building your own drone was supposed to be cheaper? even with decent motors and a shitty box goggle and controller I’m flying by the 1,000 line that would get a complete dji fpv set

>>2577600
Post your parts. You’re doing something very wrong if a generic analogue FPV quad setup is costing you $1000+.

>>2577600
That's kind of the weird thing about FPV right now. Manufacturers still think their old shit is worth just as much as before all the new, better shit got released. How is a set of HDO2 goggles STILL $500? Also, low end stuff isn't that much cheaper than then the nice stuff (except for a few standouts like DarwinFPV quads), so you might as well just get the good stuff, IMO.

>>2577600
Building isn't cheaper. However, for the same money you can build a better drone. Especially, if you catch some good sales.

>>2577395
Don't buy shit from them, and if their cuckery stops you then you shouldn't be doing it in the first place

>>2577522
That's even worse because then you have to pay the douche to do anything for else it'll eat away at him that you're doing it for free.

>>2577713
the HDO2 might be an exception. i've heard the optics are quite good, it's an OLED and has HDMI in. meaning it works with Walksnail and HDZero receiver modules

but yeah, random people selling their old shit are just as much delusional

What are the pros and cons of an 8 motor from in an 8 arm configuration vs in a 4 arm over under configuration?
Pic related but not these specifically

Also how does a 4 arm 4 motor vs 8 motor over under compare? Does doubling up on motors and propellers have and drawbacks?

>>2577780
they are pretty similar performance wise, 4 arm maybe a little less efficient. smaller/bigger footprint is the only tangible benefit.

>>2577734
>>2577839
How's the mobility, weight capacity, and flight times compare?

Also there were two questions there

Strongly considering buying a small thermal FLIR Lepton camera and seeing if I can integrate it into FPV.

Camera
https://www.digikey.ca/en/products/detail/flir-lepton/500-0771-01/7606616

Adaptor/shutter module
https://www.digikey.ca/en/products/detail/sparkfun-electronics/DEV-16779/12396902

I then somehow route the adaptor module to the VTX. From everything I see so far, they route it through a microcontroller and onto a LED screen. I could of course get the microcontoller and route to VTX, but I'm curious to know as to why this is needed. Is there ways to port directly from the the shutter module directly to VTX?

>>2577913
> I then somehow route the adaptor module to the VTX
Buy a cheap normal vision camera module first and try to sOmEhOw route it to vtx. You won't unless you have average knowledge in pcb design already.

Anyone know what connector type this is? https://m.eachine.com/Eachine-1000TVL-1-or-3-CCD-110-Degree-2_8mm-Lens-Mini-FPV-Camera-NTSC-PAL-Switchable-p-357.html

>>2577942
3-pin JST

>>2577931
The microcontroller has UART / PWM output though...

>>2577956
Does vtx take pem/uart??

Anon, I'm not him but I just wanna stop you before you waste time and money. Your setup isn't what you think it's going to turn out to be

>>2577942
Looks like JST 1.5mm, or less likely 1.0mm. That's either JST-SH or JST-PH, I forget...

>>2577857
You already have your answer - coaxial is slightly less efficient.

>>2578001
What are the two double stacked boxes with white lens

Why is the camera on a fucking mast?

>>2578001
Also does one of those limbs rotate at all?

>>2578003
>>2578004
Not that anon, but the stacked boxes are the batteries being run in parallel, the camera is on a mask because it is a 360 degree camera, and there is no need to have an arm rotate on a three armed hexacopter because because there is enough yaw authority with that many props (unlike a ghey tricopter).

Do I win a test flight on that thing now?

>>2578015
Thanks
Does it still swoop like a ghey tricoter?
What happens if one of those has a roasting arm installed, does it become better?

>>2577780
Don't listen to the idiots, one big prop and one big motor is more efficient than 4 smaller props and motors. As well as much more efficient than 8 small props and motors.

If your motors can handle two props in one shaft, then it's more efficient to get one bigger prop instead.

Efficient = more thrust/flight time.

>>2578020
>>2578015
Rotating arm*

>>2578028
I was thinking the same motors and same props but in different quantities and configurations.
I want to know drone physics

>>2578028
Coaxial setups are about footprint, not efficiency. A Y6/X8 has almost the same lifting capacity & redundancy as a flat hex/octo, but in a smaller package. For many industries (particularly cinema & inspection) the small hit in efficiency is an acceptable price to pay for the increased utility of a physically smaller platform.

>>2578042
What's the payload capacity and flight times of that thing?

>>2578032
You can build whatever you want, but you've got my answer already. The most efficient drone is picrel, can't even compare to multirotors.

>>2578042
He asked about pros and cons, as well as performance. There's only one pro in a coaxial system, that's slightly smaller size, everything else is worse.

>>2578046
I appreciate your answer but it's lacking in the why and hows.
It's not a matter of building what I want.

>>2578049
How does it affect turning and acrobatics, does the doubled up stream ever fuck up airflow and cause it to fall or make it turn like alarge boat?

I'm not looking to build one, I'm interested in this from an engineering perspective.

>>2578051
>>2578053
> How does it affect turning and acrobatics
It will be slightly worse. How much worse? If I'd have to choose one number, I'd say 25% worse.

> does the doubled up stream ever fuck up airflow and cause it to fall
No, it will totally fly.

>>2578044
It probably carries the payload in the picture for 5-6 minutes. That particular setup is essentially a freestyle quad on steroids.

>>2578049
The biggest pro for me as a hobbyist is that coaxial simply looks interesting & was something different to try after I got bored of flat setups.

>>2578053
Coaxial flies exactly the same as flat. If somebody handed you FPV goggles without showing you the drone, you wouldn't be able to tell from how it flies through the goggles whether it was flat or coaxial.

>>2578055
>It will be slightly worse. How much worse? If I'd have to choose one number, I'd say 25% worse.

I see you've never actually flown a coaxial multi.

>>2578055
Cool, thanks for answering.

I vaugly recall some phenomenon in something that might not even be drones, where some bullshit causes lower air pressure and ducks up flight.
My thoughts in my question were thinking of niche situations like "x8 will totally fly unless you full throttle against a wall where the extra flow will create a negative air pressure whereas x4 wouldn't be voiding that much air and wouldn't crash"

Is 3” props the sweet spot of being strong enough for outdoors and high speed, but quiet enough for inconspicuous city flying?

>>2578139
A 3" quad can be louder than a 5" quad, especially if you want the 3" to tear around like the 5".

Picrelated on 4S would draw attention from half a mile away.

>>2578157
Well, shit. A 3” on 4s was exactly what I had in mind

>>2578164
3" on 2S is what I fly around the house sometimes. It's about as loud as an electric hedge trimmer.

Any recommendations or tips on upgrades for this 3 inch'er?
Just set everything up and did a short test flight. so far no major upgrades besides the camera mount and piece of foam as landing gear

>>2578220
Take the condom off of your camera.

>>2578224
i keep that on if im not flying so the lens is protected

>>2578220
Is that so as loud as an electric hedge trimmer? I’m not sure how loud that would be, but I’m imagining 2 electric toothbrushes

>>2578225
Everyone does that when they first start in FPV, but by the time you turn pro, you will have stopped. It's going to happen eventually, so why not today?

>>2578227
Ok, about as loud as a toy grade rc car.

>>2578227
not sure how you have come up with such comparement but, its around a level of 80db when you measure it close to the drone

>>2578157
Redpill me on prop noise

>>2578230
>so why not today?
probably because here we even leave the protective plastics on everything

>>2578237
It can be very loud, or not so loud, depending on factors.

>>2578241
Qrd on factors

Is analog the way to go for flying around a dense asian city?

>>2578243
Cell count, motor kv, prop pitch, prop diameter, drone weight, pilot anger, neighbor sensitivity, ambient temperature, humidity, altitude, damaged props, frame resonances, God, jews, surfaces reflecting sound, solar activity, glowniggers, pinworms... The list goes on, anon, just go fly.

Anyone here fly fixed wings? I keep thinking how cool it would be to build one that can land in water to use as a scout for beaches on my jetski, but a quad is probably more practical overall

>>2578253
Ok thanks

>>2578237
More blades = more quiet, generally

>>2578257
I had an ArWing Pro for a while. It's a nice wing; lots of room inside, forgiving flight characteristics, and easily 30 minute flight times with the suggested battery.
I just got tired of not having rudder control (after getting used to being able to yaw on my quadcopters), and the fact that they blow around a lot more in the wind and shake the camera more than a quadcopter. Plus, you cant just go fly under the usual stand of trees, you need big open spaces for the speed that thing carries (90-100mph), plus a decent landing spot that won't stick-rape the foam.
FPV quadcopters are just incredible flying machines, they solve a lot of practical problems associated with FPV wings, but I still recommend building a wing to at least try out.

>>2578139
a lightweight 5" is much better imo, big blades with slower rpm is much quieter.

>>2578275
Do you think it’d be possible to waterproof it enough to land on the ocean? If so, take off and landing would become much easier with having such an open area

>>2578285
you can buy floatplane kits that do exactly that. Just swap over all the electronics.

>>2578285
You need very smooth water. And obviously you can’t use a flying wing design, it has to be something with landing gear that raised the prop up out of the water (otherwise it can’t spin).

Look up some Flite Test designs with floats, but also remember they are landing on perfectly flat lakes, no open water.

>>2578285
Well, you are probably better off conformal coating the electronics an that case, instead of trying to seal them off completely, since you do want some airflow for your VTX and ESC to keep them from overheating.
The ArWing in particular probably won't work for water landings though, since the prop will be in the water. Something shaped more like pic related will work, but you may have to get a traditional LOS kis and then modify it slightly to mount an FPV cam (not very hard on a foamie).

Does an x8 really need 8 speed controllers or can you put both motors and a single beefy speed controller

>>2578545
Sensorless motors misbehave when wired to one esc.

>>2578546
Thanks

Redpill me on senor vs sensorless motors

>>2577591
Just rc a wheelchair. Pwm solenoids are like 25 bucks and you need two and a receiver battery or a hv bec off the lead acid batteries.

>>2578549
For multirotor and 99.9% of hobby grade aircraft motors you will never see a hall effect sensor or sensored esc. Long ago when multirotors still used brass flywheel heading hold gyros, way before lipos, some good fabricators used to design their own escs, etch the pcbs in the microwave and hand wind their own custom motors or rewind old stators to new patterns to change kv, those were the last time I saw hall sensors used in any electric aircraft motor. It lived a little bit into the lipo age in big electric helicopters but even before a flybarless head was made commercially the sensor less stuff was already dominating and crushed any need for a sensored esc or motor.

>>2578557
So people really just use 2 escs per arm

>>2578563
Yup and there's even retarded hacks out there carrying real expensive gear on shitty off the shelf servo y harnesses. So if you build a double motor per arm multirotor don't be a hack. Solder splice and hardwire as much as you can.

>>2578566
>servo y harnesses
What are you saying here, I didn't mention servo.
Are you shitting on them using detachable cables or does this fuck up the motors too

Can a dji system fit on a 3” drone, or should I just go 4?

>>2578593
From my experience with a 2-3S 2.5" with a naked Vista, it could definitely punch out pretty good, but just generally maneuvering around it felt like there wasn't much grip, and just had a bit of a heavy feel with the weight. Your milage may vary, I was running a bit smaller motor than I should have.
The analog 3" toothpick I built here >>2578214 feels much more lively and responsive, with more of a glide to how the weight felt.
Pic related is the 2.5". I only flew it once with the GPS on it, because even that extra bit of weight just put it over the edge with the flight feel.

>>2578601
Is 5s or about 20v ever used with drones

>>2578593
To add to this, I took that naked Vista and put it in a 4" Shocker on 4S, and it flies much better, even with a beefy 20x20 double stack FC/ESC, GPS, and a 3000mAh Lion battery.

>>2578603
5S definitely exists, but I don't who who uses it. It is the bastard cell count of batteries.

>>2578606
Why do you say that?

>>2578608
Because most people just do 4S or 6S, and ignore 5S all together. I certainly do!

>>2578563
Of course. An X8 isn’t just a quad that uses 2 motors behaving identically on each arm, it’s an octo that uses 2 *independently controlled* motors spinning in opposing directions on each arm.

Some YouTuber was talking about 450mph prop tip speed being optimal because anything faster loses efficiency due to air compression. Is this a thing for drones, meaning I should be calculating my voltage and motor rpm by trying to get it to hit 450 with my prop?

>>2578611
Do the motors on each arm always do the same thing or will they occasionally operate at different rpms

>>2578619
>>2578611
I mean the two motors on the same arm, is it the same rpm just different directions or do the spin at different times for reasons and if so what reason would that be

I just bought the radiomaster zorro to do some simulators. Have I locked myself into elrs digital systems?

>>2578617
No, propeller tip speed should stay lower than Mach 1. Something like Mach 0.99 is also less than 1, but won't work because air going around blade's airfoil profile will increase in speed hence cross Mach 1 and create shockwaves. Each airfoil profile has its own critical Mach number, but for props it's usually around Mach 0.8 (610 mph).

>>2578619
>>2578661
Realistically they will always be doing different things & always be rotating at different rpms. Multirotors make thousands of tiny adjustments to their attitude every second & they use the balance of CW vs CCW props to control the yaw component of their attitude. Thus every single time the copter makes even the tiniest adjustment to its yaw (which will be thousands of times a second even during a ‘stable’ hover) it will be spinning the top & bottom props of each coaxial pair differently.

An X8 is logically an octocopter, not a quadcopter. All 8 motors are completely independently controlled.

>>2578684
No. You can get an external RF 4in1 module to cover Futaba, FrSky, Flysky and Spektrum protocols.

Is a 4” drone significantly more bulky than a 3”? Is it significantly less bulky than a 5? 5” just seemed a bit large and I liked the idea of a small compact drone but it’s looking like I can get enough extra thrust by changing prop size with my planned setup to offset an extra 20grams for a bigger frame, and then some. Are 4” drones “small?”

>>2578817
Depends on how thick they make it usually. My 3 inch quad is significantly more bulky then my 4. That said, the 3 can freestyle and eat dirt with next to no damage, whereas the 4 is for long range and has broken 3 arms on an eighth of the use.

>>2578755
>All 8 motors are completely independently controlled.
Thanks, what I was trying to figure out was does it have to be, and I think you answered that. It shines like it it were sensored motors you could get away with wiring them the same esc.
I think I've got the idea blue, thanks for explaining

>>2578956
No, you could never get away with wiring them to one ESC. If you were able to connect two motors to one ESC, they would behave identically - they would both have to spin the same direction & they would both spin the same speed. As far as the flight controller would know, it would be a quadcopter.

A coaxial setup like an X8 isn’t just about having two motors on the end of each arm. It’s about having two independently controlled motors spinning in counter rotating directions on each arm.

>>2578603
I've salvaged a few 6s packs with a dead cell into 5s packs, run fine on 4s and 6s spec'd quads. not a common config so not many off-the-shelf batteries.

>>2579024
Well if you wire the motor phases opposite to how the other motor goes it would spin in the correct direction

Why not y6 with rotating arm/tilting blades like a y3?
I get it's not required but why not do it anyway

>>2578593
I saw someone make a 100g O3 quad, so I imagine it's possible?

>>2579067
It still defeats the purpose. The goal is being able to intentionally create a torque imbalance. Imagine if every pair was perfectly balanced and countered itself. You'd have no yaw.

>>2579140
It's a can vs should question.
Can you do it? Sure!
Should you do it? Debatable.

>>2579283
I don't know shit about drones
Could you explain what's going on with the doubled up motors

>>2579292
The usual reasons are to gain additional thrust and redundancy without significantly increasing the dimensions of the craft. Both are important if you're flying expensive gear around.

>>2579292
Certain people in the world are lacking the part of their brain that keeps them from putting a delicate $6k camera on a children's toy that is notorious for spectacular crashes. Two props per arm is how they cope with that disability.

>>2579294
>>2579293
Yes I get the redundancy and that's cool and a good idea and all but I seek knowledge of how the motors going at different rpms accomplishes anything

Are the both blowing down or are the blowing into or away from each other

>>2579298
They are both blowing down, one into the other, 2girls1cup style.

>>2579298
All of the props have drag. When you throw off the balance, the copter will naturally wish to do a flat spin or yaw. We exploit that fact to great effect.

>>2579067
That would instantly crash, because it would have zero yaw control - there would be no way to alter CW motors independently of CCW motors.

>>2579292
You’ve already had it explained to you multiple times. An X8 literally is a regular 8 armed octocopter, but with the motors stacked as 4 pairs.

>>2579308
You're saying that but not actually explaining it
>>2579306
Is the closest to an explanation I've gotten.
It literally cannot be exactly the same, there's fucking wind tunnels and shit

I'm here for physics, not "will my toy go up"

>>2579306
Thanks I think, this is the closest to an answer I've gotten, that makes sense anyway.

>>2579320
Glad to be of help. I'm no good with the high end portions of how it all works, but I always like to get a very strong grasp of the simple stuff.

>>2579318
I’m not sure what you’re asking.

Each prop produces thrust perpendicular to its axis & additionally exerts a turning moment (torque) on the frame. Altering the balance of the thrust of all the motors is how the drone controls its attitude in terms of pitch & roll, while altering the balance between CW torque & CCW torque is how the drone controls its attitude in terms of yaw.

Stacking two motors on top of each other doesn’t change any of that. They still produce downward thrust & they still produce a turning moment on the frame.

Stacking them just reduces the required footprint at the cost of some thrust efficiency.

It’s ‘exactly the same’ in terms of how the system logically theoretically works. It only differs in terms of the physical layout & the efficiency.

>>2579324
I'm too tired for this. I thought you were saying they blew into each other creating some word positive air pressure zone
Like this
X -> <- X

Instead of
<- X <- X

Been out of the loop on RC, please help;

1) What mainly changed in the RC world since 2017? Is everyone now switching to digital FOV?

2) Why has the Hobbyking website declined? I'm surprised that some categories have so few items.

3) What does 4chan think of box goggles? I had a set of Quanums, a massive bulky thing with a head sock, but I recall the image was big & bright.

4) Is the Zohd Drift a good glider? I want a plane that fits in a backpack.

>>2579378
1.) Digital is still way more expensive than analogue. Most people getting into the hobby new are encouraged to go with digital, but plenty of us with existing analogue fleets are sticking with analogue.

2.) Some legal stuff saw them largely pull out of Europe & completely close their UK warehouse, while their China warehouse has seen ever increasing competition from banggood/gearbest/etc.

3.) Box goggles still provide an arguably better visual experience to pretty much any FatShark style goggles, but the stigma of box goggles being cheap/only for beginner runs deep. I replaced my FatSharks with box goggles & much prefer them.

4.) The Drift is a great little plane, but it is very low powered & has very little build space. I think it’s also discontinued, because I couldn’t find any for sale anywhere recently when I was looking for a second one. The Heewing T1 Ranger is the current hotness for small wings, it’s very similar in size to the Drift but much heavier, more powerful & way more internal build space.

>>2579382
>I think it’s also discontinued
the whole company has been MIA since 2020. but they just re-released the Drift as the Drift Dark Breeze

>>2579382
>The Heewing T1 Ranger is the current hotness for small wings, it’s very similar in size to the Drift but much heavier, more powerful & way more internal build space.

OK I'll look into that, now I am seeing various aircraft capable of VTOL & RTH. Which frankly suits me as I am better at building than flying.

>watch drone footage
>pilot insists on playing the worst music you’ve ever heard in your life over the whole thing

>>2579388
Many such cases. I find the silly barbershop a cappella ones to be pretty endearing.

>>2579383
>dark breeze
What are you talking about? This is from ZOHD's site.

I'm also finding tons of drifts on Chang express for $95.

>>2579421
How do you make it through the day without being able to use Google?

>>2579378
According to a recent poll, around half of people still regularly use analog. Many are running mixed fleets. I've only put a Walksnail system on my long range cruiser as it's going to be less prone to damage. Everything else is TBS VTXs and a Steadyview RX.

>>2579383
I think it was Painless360 that recently talked about them. Apparently China's retarded COVID restrictions fucked them for awhile, but they're not finished or anything.

>>2579426
Forgive me, as I expected the manufacturer to be more up to date than the insect retailers.

>>2579535
Not unusual in this hobby for manufacturers to prioritise stockists & reviewers over their own website.

>>2579388
I like analog because I can just use the blaring microphone audio.

Is something like this plausible to give a fixed wing vertical take off and landing capabilities?

>>2579566
Of course.

>>2579566
>>2579570
This is what I don't understand. Why the fuck do you need VTOL with overcomplicated mechanics, when you launch your planes with a hand?

>>2579616
>VTOL with overcomplicated mechanics
this is the simplest way to do it
>when you launch your planes with a hand?
maybe I want to land it vertically and then take off again without going over to pick it up

Regarding ELRS;

Supposing I wanted ELRS with more range (up to 2 or 3 miles), but also the bonus ability to fly different types of models, would it make the most sense to buy the 4-in-1 Zorro controller alongside a separate Ranger 1W module. Or would that be a waste of money.

>>2579616
Especially at large scales, VTOL allows you to operate from locations that you could never operate a traditionally launch fixed wing.

At smaller scales it's still a perfectly viable endeavour simply on account of it's being an interesting thing to do.

>>2579635
The radiomaster boxer has a 1W ELRS inside it if you choose that option.

>>2579616
>need
We don't do this stuff because we need to.
We do it because it's fun and interesting.

>>2579635
The Zorro is okay and all, but the batteries suck ass. I'd recommend you get something that lets you pick your battery and isn't stuck at 250mW.

>>2577943
>3-pin JST

JST makes thousands of different connector types you need to be more specific. Calling it a "JST connector" only makes you look retarded.

If I knew the pitch of the pins (the distance between them ) I could tell you. They make that style of connector in 1mm, 1.25mm, 1.5mm 2mm, 2.5mm, 2.54mm (aka 0.1") etc etc. They all look the same except for the size. The most common one in drones is the 1mm version called SH1.0 but that looks bigger. To add confusion Molex makes a connector family called Picoblade that's very similar but not compatible that Pixhawk ,FrSky and some others use.

>>2579664
All the confusion between connectors is what drove me away from plugs and towards my soldering iron. Don't have time to dig through a mountain of fucking plugs just to put a wire between two parts. My iron takes like 5 seconds to heat up, and I can pretty much sweep the wires while pulling to disconnect. Fuck plugs!

>>2578557

Multirotors never used those only helicopters and only on the tail. Multirotors didn't become viable until cheap powerful MCUs and MEMS angle sensors became a thing.

Solder joints are far more prone to vibration failure than crimps though. At least you should be putting a blob of electronics grade silicone over the solder joint on the PCB to immobilize the wire. (NOT common silicone from the hardware store that stuff is corrosive).

Couldn't find a servo breakout PCB that would do what I need so I made one that does. Basically I wanted it to provide 2S power to servos while also running the FC off the same 2S pack, and not brown out the FC below 6.5v. So this provides 5v to the FC 5v rail and powers the 3.3v regulators for the MCU and gyro directly bypassing the switching regulator on the vbat input. In theory it's also less noisy because it's a switching regulator (TPS76701). I also put an or-ing diode on there so I can connect the FC to USB with the servos powered. It'll even run a 3s~6S FC off a 2S pack. The voltage can actually go down to 4v before the 3.3v regulators start to drop out but the 5v regulator will be in dropout below around 5.2v.

>>2579688
>because it's a switching regulator (TPS76701).
oops I meant to say it's a linear regulator.

Chinese board houses are destroying the art of home made PCBs. Why bother when you can bust out Kicad or Easy EDA or whatever design what you want and have 20 copies on your doorstep for 5 bucks a week later.

>>2579754
If it can be done in a week for 5 bucks, then it's not an art to be honest.

>>2579683
If I somehow metal fatigue something, I'll just go collect it from the field and melt the fucker back on.

>>2579762
>>2579683
If you are looking for cool, sturdy, aviation-grade connectors that are also affordable look at GX12 ones. Not for small models and fpv though (15-20g per pair).

Why sellers don't specify the specs of brushless motors and why don't you demand it from them? I need to know the rpm, torque, operating voltage range, current draw or power. Like for fucking sake it's basics.

>>2579669
There were definitely physical gyro miltirotors, check YouTube if you're interested. I'm not saying they were any good, but people definitely made them.

>>2579822
Except for torque every reputable motor manufacturer will tell you all of that.

>>2579755

It can be done in a few hours by a board house because they're a fucking board house, it's just the queue and shipping that makes it take longer. Making a PCB at home is a whole different thing, used to be electronics geeks and hams would make their own PCBs using copper clad FRP, printing or drawing on resist, etching the PCB with toxic chemicals that were a giant pain in the ass to deal with, drilling holes, putting in though holes (Pace made stuff for pressing copper rivets in for that actually intended for PCB repair but could be used to make PCBs too) and adding crating the solder mask, etc. You could get a near professional looking PCB if you were good and people did this because PCBs had minimum orders of thousands or tens of thousands to make it cost effective. But the way they did it was nothing like how the PCB manufactuiers did it. Then in the mid 2000's cheap online services that woulkd collate orders started popping up online, then the chinese noticed this and undercut them and now you can have a run of 20 PCBs made for nothing, and the skills for making PCBs in the home aren't being passed on because the kids don't give a shit they'll just have JLCPCB or PCBway or whoever make their boards.

But on the other hand you can have a truly professional PCB made for cheap now, even 4 or 6 layer stuff that used to be out of reach of electronics hobbyists.

>>2579873
Speaking of passing on knowledge, every electronics nerd should watch these. Still relevant and way way better than the instructionals they make today.

Main channel with playlists are here, they've basically put up their entire library. Very good information and training that every electronics nerd should watch. Make sure to watch the series on PCB repair. I never knew you could fix a board with a hole burned through the middle and have it come out looking almost new.

Yeah, even 5g for a connector would be a deal breaker for most of what I fly. Been flying all last year and never had a wire detach. That's after three broken arms, two broken motors, and several bags of props. My iron is my best buddy. Connectors outside of XT30/60/90 can go to hell.

>>2579875
>>2579878

I saw those when I was in the US Army. It was part of the training curriculum for 29V strategic and tactical microwave systems operator/repairer. I worked mostly on MSE mobile subscriber equipment.

Instructor was a dick when grading solder joints.

>>2579683
>Solder joints are far more prone to vibration failure than crimps though

Connectors that are attached to the PCB via SMT are far more prone to shear off the board than a wire hand soldered to a larger pad.

PSA... these things are an electrocution and fire hazard.

Not everyone into drones is a Bardwell-esque faggot.

>>2579952

QS8 is an 8mm version of the XT90S and barely bigger than an 6mm RC Proplus connector. Awesome for anything big like a 700 size helicopter or a large plane. And they're relatively inexpensive too. I reccomend you use a beefy iron for these (at least 120W).

A temporary strip of kapton tape around the back of cup type terminals like on QS8, XT90, etc will prevent the solder from flowing around the back and forming a blob. Just take it off when you are done. Yeah it's a crutch but accidents happen and I don't like to be punished for a mistake by redoing a connector.

>>2580151
>Honestly the most gigachad option would be a nitro RC helicopter

No the gigachad option is a turbine heli:

http://mpeer.at/whiplash-turbine-prop-report-translation/

$1500 for the kit and around $6000 for the engine (that's just the engine not the engine management module that's another couple thousand on top of that). And if you're spending that amount of money you better buy $400 "high reliability type" servos from Futaba or Tone or whatever because when a turbine R/C crashes it becomes a fireball, total destruction.

Helicopters change the angle of attack of the rotor blades collectively to control lift (positive or negative) as well as cyclically for direction control.

https://www.youtube.com/watch?v=YEKBQtkAvGg

Cyclic pitch changes the vector of the outflow from the rotor. The rotors are really a rotating wing not a simple prop.

>>2580550
To be fair, some shitty RC helicopters are fixed pitch, but most serious RC helicopters are variable pitch, constant speed.

>>2580455
Leaf blower start.

>>2580456
Belts are without a shred of doubt, worse than gears. Why don't they just direct drive a big friggin hub motor and have a cute little 36mm stator for the tail rotor and get rid of all the indirect drive?

That's thread about drones right? I just wanted to say that USA is a bunch of cucks like most Europe. You will happily allow enemies destroy your drones while simultaneously being extremely concerned. Big humiliation and loss of self respect.

Haha, this fag is mad he doesn't have a fun hobby!

>Build this drone in 5 easy steps
>Step 1

Whats the point ? Wheres the fun in that ? There is no soul, i'd rather play with legos. I want to do everything from scratch write my own PID loop, write my own comm protocol over a datalink, write my own INS, do computer vision from the drone. But every resource on google is a blog post written by some indian tech "blogger" that got copied from somewhere else, probably not even writren by a human at this point. And it always says to buy X brand(TM) flight controller install ardupilot and communicate with the drone on fucking wifi or a custom Y (TM) radio link.
I do understand that you need mems gyros, magnetometers, GPS modules and accelerometers and the best way to get all of that is to fused them in to one board and call it a flight controller but using one feels like cheating.
Anyone built your own flight controller for fun before ? Im thinking of something that does flight control in an esp board and high level navigation/computer vision/datalink over lora/4g on a raspbery pi with cameras and widely available modems over USB. Anyone did something similar ? What were the main problems or roadblocks ?

>>2580811
The rocky diy roadblock that was slowly chipped away that paved the path to the off the shelf ready to fly or setup flight controllers is that your multirotor can crash immediately or crash later. Knowing why it crashed can be difficult to diagnose. You might crash dozens of times dialing something in. You might solve one problem and make 3 new ones.

>>2580715
>your drones
I think you meant the jews' drones, gypsy.

>>2580811
I enjoy the soldering, 3D printing, problem solving, and endless skill ceiling for flight. Plenty of reason for me to continue.

Spotted the Wagner pidor...

Digital FPV is so expensive vs analog. HDZero goggles are $600.

>>2580234
True, most are even more gay

>>2580575
Because for a heli that size the motor would have to be around 30kv, which would require a huge number of stator arms and magnets which would be stupidly heavy.

Putting a brushless motor in the tail on a big heli means you need something like a 4025 class motor on the end of the tail not to mention running like 12 AWG power leads out there and a second ESC. That's way heavier than a belt and pulley or an aluminum tube shaft and a couple delrin bevel gears.

And you'd still need the rudder servo and tail pitch mechanism. Direct drive fixed pitch tails have been experimented with on large helicopters and they don't work well.

All of the world record holding speed helis are dual belt driven because they can handle the torque while still being light, gears that could handle that amount of power would be too heavy.

You actually nailed the problem. I have similar experience in this hobby but with a rocket model. I asked in /HAM-thread how can I transmit and receive telemetry several kilometers away using diy solutions, nobody answered my question, only some random shit. They have no clue how things work internally I assume. Their best answer was to buy a complete off the shelf RF box (which takes most of space in the rocket and is expensive), buy off the shelf receiver and using a hack maybe receive the data. Like lmao wtf. Same shit on a RF forum. Same shit here, you can ask basics about comms and people here will just tell you what brands off the shelf solutions to buy.

Forget about comms, at least we still can do the mechanical and electronics part ourselves.

/diy board by the way

>>2581125
Just remember we're in the end times and being an intellectual gets a bounty on your head.

Can confirm, Hamfags are buyfags too. There's a few that can tell you how to diy filters but the time of the greybeards is gone. I'm afraid for the future, and the loss of information is about to be crippling. Every day more and more websites get taken down that have info that's still needed and doesn't exist anywhere else.

The current state of things is the work of people that meddle with society. There are groups. They wanted to compartmentalize everyone and prohibit knowledge outside of people assigned careers. They want a society that consists entirely of people that are both profitable idiots and full time consumers in the same person. Try talking to anyone about barrios thinks, you'll just get that fluoride stare. Talk to them about their career and they'll act like they have a PhD because that's all they know. Try to tell them anything and they'll call you a liar because you're not employed in said field.

Even fields are compartmentalized, and anyone smart enough to fuck up grand schemes winds up dead. There's a list of biologists that have been murdered in the last few years, it's incomprehensible. Right before COVID a plane with all of the worlds top HIV experts was shot down on their way to a meeting.

I’m talking as a computer scientist more than as a dronefag. Writing your own flight control stack from scratch would be a serious solo project even for an accomplished embedded developer, the sort of thing which would take 6+ months of their free time. Just take a look at the codebase & commit history of even a relatively basic & outdated flight control project like multiwii to get an idea.

I’m not saying it’s not possible, rather that it’s not the scale of project that most /diy/ers want to take on.

>>2581149
All modern radios are spread spectrum frequency hopping affairs. They automatically jump around different frequencies within the permissible range to automatically handle congestion - you don’t need to manually choose frequencies & swap crystals, you just meet up with your friends & everybody powers up their radios without a second thought.

You don't have to invent the phisics from scratch. Taking existing algorithms and using them in your code is simple and fast. For example here is the complete code for a controller which does what you want it to do https://github.com/nickrehm/dRehmFlight/blob/master/Versions/dRehmFlight_Teensy_BETA_1.3/dRehmFlight_Teensy_BETA_1.3.ino
Most of it is just definitions routine and third-party algorithms like filtering. Anyone can do the coding part in couple of weeks.

It's amazing to me that Skyzone and Fatshark haven't caught on that their analog goggles aren't going to sell for that anymore.

Hi I was sent here from /[board redacted]/. I'm about to spend 1000 burger bucks on a DJI 3 pro mini with all of the fixings. I want a 'smart', easy to use setup for live observing at a high resolution (both in motion and stationary) and it seems to be the ticket, with the 1080p streaming and good software.

Anything to consider before I buy it? Or should I look for a different model? thanks.

>>2580970

>Could you tell me what would be the optimum RPM of main rotor in a heavy-lifting 700 class heli? No acrobatics, I would like to optimize for the flight time and fill all possible payload with batteries.

As low as possible while still maintaining an acceptable level of lift and maneuverability. Also they make asymmetrical blades for lifting applications. These have an airfoil shape designed for lifting not working equally well in both directions.

It really is as simple as "slower = more efficient" I can't give you an exact RPM but around 1600rpm or lower for a 700 (it depends on weight and if you are using 690~720mm blades). Start with 1600 and test to see how much control and lift you have and adjust lower till you get an acceptable compromise (remember you want enough lift to get out of trouble if you need to)

Also be aware that vortex ring state (google it) becomes a thing that actually exists with low RPM /high efficiency lift platforms. Aerobatic helis have such high RPM and lift to weight that they can basically just power through that without you even noticing. But with a lifting platform if you do the wrong thing it can go into vortex ring state and drop out of the sky like a full scale heli if you do the wrong thing (descend too quickly and then apply collective too quickly to stop the decent).

And before anyone says anything large multirotors lifting platforms are susceptible to that too. Higher disk loading makes the problem actually worse (see the V-22 and all of it's ring vortex state accidents as an example)

The terrifying truth is you don't need a team or top experts to make something like covid or even something much worse than covid an intern could design and make something like that. All you need is the equipment and a person that's enough of a nihilist to do it.

I remember a webcomic called Genocide Man where a genetic engineering kit sold as a toy to make designer hamsters gets rootkitted by hackers and then starts getting used by terrorist groups to create apocalyptic plagues because it's just that easy to design a world ending virus and only the equipment necessary to actually synthesize it makes it difficult.

For the ultimate clean wiring. Also apply electronics silicone to the soldered wires on the FC (you want the self leveling not the non slumping)

is there a tool to easily take of tiny whoop props?

You must have an observer with you when flying FPV (in the UK). So every YouTube reviewer in the UK is not following this rule in every single video they make.

https://register-drones.caa.co.uk/drone-code/the_drone_code.pdf

Thoughts? Do you worry about this at all, especially if you have GPS RTH. Do you think it matters, if you stay within LOS, you're within the spirit of the law? Or just fly well away from other people, for example using a mountain bike to reach your setup position.

When I was dabbling with quads in 2016 I didn't worry about this stuff. I actually don't mind the registration or the 250g rule.

>>2581638
The registration isn't supposed to be very bothersome. It's a start point to creep more shit into the rulebook.

>>2581535
Okay bro.

>>2581638
I used to fly FPV with a police officer & we discussed a lot of the regulations. The reality is that the police don't have time to deal with anything unless it poses an immediate threat to people, property or privacy. If you're respectfully flying FPV in a quiet area, not getting too close to anybody & not obviously trying to look through windows, they don't care. Even if a knowledgeable passerby did happen to see you flying without a spotter & called it in on 101, the police wouldn't attend.

Furthermore, the police themselves are incredibly unlikely to know the minutiae of the regulations. I've had police come up to me when flying FPV clearly by myself & they just wanted to have a look through the goggles because they thought it looked neat.

As with most things, stick to the golden rule of "don't be a dick" & you'll be fine.

>>2581661
Does critisizing and insulting others ease your pain? Not good enough for mommy and daddy? You should seek professional help. Now go away or kill yourself... I don't care which.

>>2581615
About 4-5 minutes when the batteries are new, down to two minutes after the batteries have been beat to shit from hundreds of abusive flights. It's really not too bad, you actually kinda need to take a break after flying freestyle for that long. I take 6-10 batteries when I go fly usually.
I can get 10-20 minutes on both my 4" and 7" LR quads if I feel like flying longer.

I assume you're not talking about the mutt force? because they absolutely have nothing better to do.

>>2581672

I'm kind of screwed anyway though, I live in the New Forest and it's one of two places in the UK where any model flying is outright banned, due to nesting birds or whatever.

I want to make a sub 250g Fixed wing but i don't like all the models on sites like flite test. I don't like the 'realistic' airplane aesthetic i want something that looks robotic like a drone. Any suggestions?

>>2580715
Don't you have any more missiles to shoot at polish farmers or are you still begging for those?

>>2581559
Kek, I can hear the music already

>>2581781
Are you looking for something beyond just a flying wing design?

>>2581781
there is a reason why planes look like planes
but have a look at the models from ZOHD

>>2581758
you need to still be LOS with a spotter in the UK anyway so you were already fucked. Just don't comply and enjoy your hobby.

>>2581837
No just airplanes in general. The type is not important.
>>2581838
>there is a reason why planes look like planes
I don't think that there is a good reason to have a cockpit window in a small rc plane. But the ZOHD frames look nice that's what i was looking for.

I want to check out the beavers in my marsh. Are there any good RC submarines?

>>2581904
I'm a bit if a beaver diver myself, can be a bit daunting the first couple of times but you soon get use to it.

>>2581905
Why do you need radios if you are not allowed to fly drones anyways?

>>2581684
Do I have to grow my own hemp and design my own knot?

>>2581736
Learn to design your own. Given what's out there, it's easier than you might think.

>>2581842
This. Why should your government get to lay claim to the whole sky? Do a quick rip away from prying eyes, pack up, and leave.

>>2581925
ok. I haven't been in the hobby since ~2014. I assume a lot has changed then?

>>2581929
I've been in it for a year and have already built three. Watch some build videos and things will start to make a lot of sense in a hurry.

>>2581934
will do... does anyone actually give a crap about RID? looks like we just don't comply?

>>2581943
That's cool bro, that's cool. I can't do what I want cause every german will report me flying on a field. I can only use my own land, which I obviously don't have, or apply to a club and fly in model airfield. For that I would need a license, an insurance, drone registration, line of sight and a person watching me flying.

>>2581758
I feel your pain. I moved from Scotland to Bucks last summer & there’s nowhere to fly down here.

>>2581947
Sure man, I'll even give you some suggestions now if you already have an idea of what kind of flying you wanna do.

>>2581950
a buddy in (east) germany flies at the city center, parks, down streets and doesn't give af. noone has said anything
you can also hide a little so people just won't see you at a field

>>2581956
Sure; basically high-resolution live video flying up to ~2km away. A gimbal and zoom camera is a must. Not going to be flying around trees so I don't need prop guards or avoidance sensors. Just boring video... cool kid fpv aerobatics aren't my thing at the moment. Would like to have some semblance of 'smarts' so I don't need to care too much about light wind or station keeping. I assume that, and features like GPS return to home auto-flight, is kinda trivial with modern software/controllers?

Are there equivalent kits to the DJI O3? (basically higher end camera transmitting hardware)

>>2581950
Just find a place in the countryside, nobody can report you if they can't see you. Make a day of it and go see some remote places you would have never gone otherwise.

>>2581954
I go up the munro's every weekend, weather permitting, endless countryside in Scotland to fly about in.

>>2581984
Like where? Everything is privately owned or is a natural reserve with birds etc... Or at least that's what I see around me, I'm not german and that makes me worry even more. I like taking photos, and once I've stopped at a random field and started taking pictures of a sunset. Literally the next car stopped nearby and the german lady started asking who am I and what I'm doing lol. Like wtf bitch can't you see I'm holding a camera and can't speak the language properly. At least she didn't call the cops on me.

>>2581560

>Take the Hot Glue fetish back to /3dpg/, pervert.

It's self leveling electronics grade silicone not hot glue you retard. This shit is made for use on electronics for things like fixing IPX antenna connectors or stand up components so they don't vibrate loose or potting and sealing applications. Hot glue is garbage that will eventually come loose this stiff will last decades.

Here: https://www.digikey.com/en/products/detail/chip-quik-inc/CQ512-20G/15973927

Also comes in black or white if you don't want it looking like semen. I prefer the clear because it lets you see what's underneath and it does no harm if you put it on an LED. This stuff is great for preventing soldered wires from vibrating loose just put a little blob over the solder joint and it'll immobilize the wire. Best thing is that it actually bonds to silicone insulation. You coma get it off the PCB if needed just takes a little work with tweezers and a wooden toothpick to scrape it off. But if it was too easy to remove then it wouldn't do it's job.

Every fighter jet ever made has electronics with the boards covered in silicone or urethane potting compound btw.

Also NEVER use normal silicone from the hardware store for this, that stuff is acid cure and will eat copper you need neutral cure electronics grade silicone.

>>2581993
Never stayed in Germany, but it's not tokyo levels of urbran density. There's parts of Germany that are very rural, down near stuttgart is all mountains. pick a random hill and have fun.

>>2581995
never seen anyone put silicone over their joints other than for waterproofing. if your solder joints are breaking you should do a better job of soldering. the pad would rip off before my wire comes loose.

>>2581711
>wrangling an inkjet printer to produce useful stencils for your shitty single-sided PCB that still requires skin-eating cancer juice, insta-blindness lasers or a $5000 CNC machine to etch
>""art""

Yes there was an art to it. Though when I did it home inkjet printers wouldn't be a thing for at least a decade so we just drew the circuits with a fountain pen or used rub on stencils. If you could afford a home computer there were some crude programs to assist with the circuit design.

Also we could make double sided PCBs not just single sided.

>>2581989
I used to visit a perfect spot near Pitlochry, literally not another person for miles. England is shit in comparison & the job I moved down here for is toxic as fuck, I’m really regretting it now.

>>2582001
Want to add that I hadn't messed with circuits for over 2 decades till recently, found out about Easy EDA and JLCPCB. After using that I wouldn't make my own PCBs either. But it's still sad to see the skills being lost.

>>2581999
Look inside any good air servo and you will see the leads between the PCB and the pot blobbed with silicone as well as where the main lead is soldered to the PCB and any metal can caps. Any unprotected solder joint to a flying lead is a ticking time bomb especially with IC aircraft.

And on military aircraft they basically encase the whole PCB in a block of urethane potting compound.

Picture is inside GDW BLS992, $90 servo for helicopters. They come from the factory this way, same with KST and pretty much any other quality servo brand.

>>2581978
I know how to get you the range, but when it comes to cameras, DJI has the best live video. Now if you don't mind using a separate action cam, you can get HD footage while retaining options on the FPV feed. When it comes to autonomous stuff, you're either going to want iNav or ArduPilot. iNav is easier, but far more limited.

As for size, smaller copters will save you money, but will have less options available, less payload, and less tolerance for the wind. I used to do long flights on 4 inch props, which worked, but was slow and shaky. Now I'm running a bigger one with 7 inch props. Loaded weight is 1580g, has a range of 11km before needing to turn back, and it handles wind like a champ. Using ELRS 2.4GHz for control and Walksnail for video. Don't really care about the footage as I'm just exploring and cruising around.

>>2582002
looks banging. once you get up into the Cairngorms, away from the roads, there's an eerie silence of isolation. Can just do whatever you want, rode my bike up a hiking trail for about 2 hours last week and only seen 1 other person, must have been me and him within a 15 mile radius.

>>2581999
It's not about preventing the wire from being pulled of it's about preventing vibration from fatiguing the solder joint. This isn't a big problem with multirotors but it is with helicopters and IC airplanes that have strong vibrations. The wire moves and the solder joint doesn't and the wire is essentially being bent back and forth a tiny amount thousands of times per second until it just falls off the PCB like bending a coat hanger till it breaks.. A blob of potting compound immobilizes the wire and fixes it relative to the solder joint in order to prevent this from happening. This is standard practice in electronics to be used in high vibration environments.

>>2582016
If you want something with more tolerance for wind just get a helicopter.

>>2581997
I'm not far away from the coast up north..

>>2582016
I think I'll stick with o3 for the video then. ArduPilot looks nice and widespread, I'll use that.

>>2582027
hm, maybe not. I really would prefer to have built-in zoom and gimbal. I'll poke around more

>>2582026
People dont care about people who do RC even in Germany. I flew my drone around in a park and there was just this one turk that wanted to see through my googles. And the other time i was in the same park with my 2m antenna and my thinkpad looking like a terrorist nobody cared. Just dont fly your stuff over people or homes and your golden. Just stay away from old people and women they might make a fuss...

>>2582026
looks pretty green up there, ignore the no fly zones and pick a random field, windmill farms are pretty good places I found, nobody goes there and they are normally open to the public and away from population centres. not sure what german windfarms are like though.

>>2582038
>one turk that wanted to see through my googles
Did you show him?..

>>2582043
As i white boy i didn't really have a option. At least he liked it.

>>2582042
>>2582038
It's written everywhere that I would need to have a permission from landowners to fly over their land, even if there's no buildinga or people. How important is this rule? Other rules are doable but this one looks too bad.

>>2582048
who cares, just ignore it, be a big boy and dont let the gooberment ruin your enjoyment in life. the consequences if you play ignorance is minimal, slap on the wrist. do it till you get caught.

>>2581742
Probably a dimb question but do you just fly slower or is there some other trick to getting longer flight times?

>>2582048
Yeah but i don't think that every inch of land is monitored 24/7. And from what i know the airspace is property of every citizen so there is that. Also farms should be safe as long as you don't enter their property on the ground. But don't try to record or annoy the farmer.

Just do what >>2582049 says and have fun. As long as your not in a turbo alman area rules are more like guidelines.

>>2581954
>I feel your pain. I moved from Scotland to Bucks last summer & there’s nowhere to fly down here.

I might scope out a spot well away from cars and dog walkers. I can break down a foam glider into a backpack. The intolerance was always going to happen when the DJI/drone craze started in the mid-2010s, it didn't take much for a minority of dickheads to upset the NIMBYs. I think planes, especially compact ones, attract way less negative attention than drones.

>>2582050
not him but if you fly smoother and just cruise around, the draw on the battery will be much lower
you can also put bigger batteries on them or different kinds that aren't suited for acrobatic flying
he also calls them LR quads so they might be specifically constructed for that: 2 bladed props, low kV motors, light frame, etc.

>>2581742
Gasoline heli can fly for 40 minutes.

>>2582030
Idk about zoom, but a gimbal is a rather simple thing to create and control. Cinema is where the holes in my knowledge show because I have little interest in that.

>>2582086
>Implying I would make it more than 40 seconds without making a cloud of helicopter confetti
Sorry, boomer, I simply cannot afford it.

>>2582142
>boomer

Born in the 70's so you mean Gen-Xer.

>>2582142Helicopters are actually way easier to control than multirotors. They're inherently more stable, you actually have a ghost of a chance of not crashing with no stabilization, a multirotor without stabilization is simply unflyable.

Modern FBL systems (what heli guys call an FC) have all the same rescue and self leveling modes that multirotors have. Hell they even have a fork of Betaflight now (Rotorflight) that's literally just Betaflight for helicopters.

>>2582181
I'll tell you what: if ShiMask goes to $10M market cap, I'll buy a hyperactive choppa and 3d print a Sad Pepe canopy for it.

>>2582181
You can talk stability all day, but until I can crash it without making a pile of broken parts, I'll stick to my little 3 inch quad. I fly the trees most of the time, so branch strikes happen almost every flight. Can crash that little bastard a few dozen times before it needs new props.

Are the only advantage of fixed wings compared to quads the longer flight times? Scale model RC airplanes are big ugly, but the fixed wing FPVs like the Caipirinha 2 look awesome and I’d love to try one but other than cruising over the city I’m not sure what I’d do with it

>time to learn to fly quads
>plug in radio controller and load velocidrone
>literally unable to fly through a single hoop
>after hours can fly cautiously in a circle with no obstacles in the way
Am I missing something or are drones just massively difficult to fly?

>>2582336
How can you keep crashing when even cheap chinese knock offs have 360° collision sensors on their drones?

>>2582410
Anything other than DJI type drones have a learning curve, but are definitely much ore fun to fly.

>>2582410
It's best to start with something cheap like a Mobula7 1s.

>>2582410
Learning curve is steep, but very rewarding if you stick with it. Concentrate on pitching forward to maintain some speed, don't try to hover until you get a bit more experienced.

>>2582410
took me about 10 hours to get the hang of flying about doing no tricks, and landing. Once it starts to click, you get a lot of confidence and then its pretty linear learning skills and tricks.

>>2582411
I'm busy doing freestyle aerobatics, not semi-autonomous photography. With Betaflight, the flight controller isn't concerned with avoidance or flying the thing for me. I'm seeing what kind of BS I can pull off, and it's a blast!

Hot glue is crap, it eventually comes loose. Use this shit instead: https://www.digikey.sg/en/products/detail/chip-quik-inc/CQ512-20G/15973927

When would I want to use negative weights in the mixer tab vs a reversed servo in the outputs tab of inav? this is for a 3 channel plane (zohd drift). pic rel works perfectly, but couldn't I essentially reverse a servo output and weights and have it work perfectly as well?

>>2582659
You could also put your servo arm on the other side. I FUCKING LOVE SCIENCE!

Is fitting the dji wasp camera set in a 3” frame easy enough? It’s the one thing I’m not sure about the parts I ordered

>>2582643
I used to use plastidip. Peels off cleanly in a single piece, even from between wires/pads.

>>2582728
Well, fuck

Is bottom mounting plausible, or is this frame just completely incompatible?

>>2582772
>>2582782
It would fly like shit regardless.

>>2582733
Clean work buddy.

>>2582772
Like a fat person in a little car lol.

>>2582796
So I should just put it on a 4 inch frame?

>>2582802
look at the last pic and take a guess if one inch will change anything

>>2582830
Well turns out the camera doesn’t fit into the cover anyway and the arms need to be dremmeled out a tad for the motors to fit, so fuck it, I’m taping/zip tying this fucker on there, and it’s looking much more compact. One more inch should help with thrusting this giant piece of aluminum into the air at least

>>2582715
Yes but is there a programmatic benefit for negative weight vs a reverse servo setting?

>>2582877
Well, the contol rod geometry might make things feel a little weird.

I keep seeing stuff like picrelated advertised on LinkedIn, but I cannot fathom who is actually buying these things. Surely they wouldn’t make them unless there’s actual people buying, but…

Nitro first flight. Was a little windy

>>2582772
There's a reason manufacturing was ended on the Air Unit. You are going to want to use a Vista, possibly a Naked Vista, if not just going with HDZero instead for the much lighter VTXs.

Question about iNav RTH behavior: if i flip the switch for rtl, does anything like moving the sticks take it out of rtl or do I have to disable that flight mode to exit?

>>2582954
I would buy that if I had unlimited money, it looks cool

Does the ADL know about this hateful threat to their nation yet?

>>2583099
My problem is I already invested into the DJI goggles, so I (presumably) need a DJI vtx to connect them. I don’t know, I’m still new to this obviously. I’ll try to return the air unit but I’m tempted to just strap it to the frame with electrical tape and call it a drone

The new quiet props from Zipline are pretty interesting. Stacked, counterbalanced design that reduces the peaks so the noise is more of a lower continuous background noise.

>>2583332
Move over Toroidal meme clickbait we got a new prop king in charge

>>2583328
I’m sure he has helpful content, but that voice is just too gay to listen to

>>2583344
Interestingly one of the engineers has been commenting on Reddit & addressed toroidal props - apparently they induce too much drag for fixed wing forward flight (the Zipline stuff is all fixed wing or hybrid VTOL fixed wing).

>able to return my misfit runcam and frame
With 1408 3750kv motors, would it be better to go for a 3 inch frame that will leave me with an AUW of 207gm or just add 8 more grams for a 4” frame and run slightly larger props?

>>2583459
Really, you could do either way. The difference won't be huge. You'll just get more speed on 4 inch props, so decide how fast you actually want to go. It's already going to do 80+ on 3 inches anyway.

You will never be this good.

Thanks, just bought 100k F4s.

question from a noob. Is there something like the Mini 3 Pro DJI but in the fixed wing, pusher/puller category? Like buy it and be done, ready to fly, hand-holding sort of deal, with excellent camera quality (live streaming to the ground, gimbal and zoom). I realize now for my loitering, filming purposes some sort of efficient delta wing that can hold a position within 50 meters or so (doable with turning radius?) is fine - so I don't necessarily need a quadrotor.

>>2584238
Not for any consumer price. I don't know of commercial ones either. Closest "hold my hand" I've seen is the Hubsan H301S Spy Hawk. But you're asking for features of a home-built plane.

>Been out of RC for a while

Just an FYI the Invensense MPU6000 is EOL and will only be around until the "last chance to buy" batch of stock from 2020 finally dries up. The best of the newer gyro chips for R/C appears to be the Bosch BMI270 which testing has shown is actually slightly more noise resistant than the MPU6000 when operated in 4x oversampling mode. However, it's refresh rate is 3.2khz vs the MPU6000's 8khz. That only matters with an H7 processor though because you have to run the PID at 1/2 the gyro rate even with an F7 and with the BMI270 you can run it at the full gyro rate even with an F4 so you get no aliasing in spite of a slight reduction in refresh rate compared to what you'd get with the MPU6000.

And it's cheaper than the TDK/Invensense gyros too, and more crash resistant, so win-win.
