[Anonymous No.1511307]

Itll do the job but most people will tell you to start bigger on certain things, mainly transmitter and charger. The Flysky TX and that tiny little Charsoon charger work, but they are in no way shape or form anything above average. If you get more serious into the hobby youll be replacing both almost out of necessity.

First of alot of people will tell you to just spend $100 on a Taranis QX7 and something like Velocidrone or Liftoff. About $120 total for the TX and a simulator will give you a feel for whether you want to persue the hobby more and spend more, plus the simulator is a good way to get your first few thousands crashes out of the way and get some experience without breaking anything.

After that if you decide you want to spend more and get a real quad that one will fly, but unless youre specifically interested in the 3D printed aspect there are definitely better options.

[Anonymous No.1511329]

>>1511262
I also suggest the q x7
There are several free (or trial) sims and you should fly in all of them
The quads fly slightly differently in all of them, and after flying them all you will have no problem flying the real thing

Read the sticky. And I agree with the anons suggesting the QX7. I started out with a cheap transmitter and it was a big waste of money. If you want to get into the hobby there are tons of dedicated websites and forums, don't rely on a 3d printer website. You can 3d print camera mounts, antenna mounts, and other little parts, but get a carbon fiber frame.

[Anonymous No.1512025]

I just got my new motors and when I'm test running them at lower ranges of RPM I hear this strange ticking noise, kind of like an old floppy drive but softer. Is it missing steps or something, do I need to worry?
>>1512013
Most receivers have some sort of output plug, the most common is simple composite video. You could plug the composite RCA into an adapter, there are ones that behave like a webcam on the laptop so you can use all sorts of software to record and view the video. https://www.dx.com/p/easycap-usb-video-capture-adapter-2004780

I wouldn't recommend a laptop though, screen glare from the sun makes it very hard to see anything. The benefit of goggles is that they block all exterior light, and the benefit of these screens made specifically for FPV is that they come with a sort of box on the front that blocks light. Bring your laptop outside on a sunny day and try to watch a movie on it, you'll see what I mean.

Easier, yes, but more than a bit more. I don't know if I'll commit to RC as a hobby and so don't want to spend 50-100 on a transmitter and another 15-20 on each receiver - I was going to build my own controller. I assume the serial output from each transmitter manufacturer is decently documented but I still worry about interpreting it. I suppose I would then be better off programming a purpose-made servo controller (like https://www.amazon.com/dp/B004G54CHW/)) rather than fussing with an arduino?

[Anonymous No.1512251]

At my house I have some spots nearby that I have flown on 2.4 and they were abut 300 feet away with a bunch of tree's. It was kinda risky on 2.4 because RSSI was low and if I flew too low I could get drop outs or maybe failsafe in the wrong area.

With 900mhz is really easy to fly those close spots but I also think I can push out even farther through more trees out to some big open fields. Its winter time now so long range testing is harder with all the snow but I think I can stand on my roof and fly all the way out.

I think the triple feed array antenna will also help to push through the trees. I can put a couple of them on a ground station and get much better image then with my fatsharks through all the trees. And I will have a pretty wide area to fly in.

The Half Overlord would be nice but its about $150. I think I can get the Lumenier for $40 and each Array antenna is $20. So about half the price.

[Anonymous No.1512335]

That anon is talking about 5.8GHz so they're obviously talking about video, not control. Having an easy 4km R9 control link is useless if you're 5.8GHz video craps out in a quarter of that range.

>>1512013
There are 5.8GHz receivers with USB output to connect to a phone via OTG, however they have too much latency for flying freestyle/racing miniquads.

>>1512142
You can buy 100mW 3DR/SiK style 433MHz/915Hz radios really cheap, there's plenty of experience out there about their range/performance if you search. A 100mW 433MHz module should way out range a standard 2.4GHz RC control link though.

[Anonymous No.1512500]

The Idea is to put the R9M up in the air with the ground station for best reception.

[Anonymous No.1512502]

This is an R9M module bay adapter.

you just plug your module into it and then you solder the wires to a 25 foot Midi 5 pin cable and at the other end you solder the other connector that goes into your radio.

Why are these low frequency tx/rx not just the standard that everyone uses?
Like, why have 600m range when you could have 6km range instead?

[Anonymous No.1512713]

>>1512696
Because spread-spectrum technology is only commercially available at 2.4 GHz, which was where it started because it's an easy bandwidth to use from a legal perspective. Without spread-spectrum you need a crystal to determine your frequency, and you're vulnerable to "jamming", for instance if certain electronics are turned on and they just so happen to mess with your particular frequency, or if someone else is flying near you and happens to have the same crystal, your plane will just drop out of the sky. 2.4 and spread-spectrum means that if one frequency gets jammed, the RX and TX immediately switch to another, and cycle around until they find a clean frequency, which happens so quickly you don't even notice it.

Before spread spectrum, RC clubs had these boards where you'd clip a padlock onto the frequency you would be using, and you'd have a bag of spare crystals prepared. Even so retards would show up, not check the board, turn on their radios, and crash someone else's plane. 2.4 can support hundreds or thousands of radios broadcasting simultaneously, so it's easy to see why everyone moved over to it. Limiting your range to "just a few" kilometres instead of "dozens" wasn't actually a problem, since people who fly at such long distances are very rare anyway.

[Anonymous No.1513040]

[Anonymous No.1513242]

>>1512696

2.4ghz is convenient because the antenna are small and you dont have to worry about tuning.

The 900mhz system is a bit more complicated because the antenna are bigger and you need two of them for best reception. Also you need to worry about cell phone interference and specific tuning for the region you live in.

So this added layer of complication means that most people use 2.4 and if you want you can get the long range stuff.

Huh, I didn't know anyone had made spread-spectrum 900MHz radios, cool.
>>1512696
In this case, the only reason to go 2.4 is that they're cheaper, almost everything is already DSMX 2.4, and you use a much smaller antenna. If you don't need to save every single gram of weight and don't mind the extra cost, yeah, absolutely go for the 900MHz radio. There's less interference in that range anyway, these days every single gadget mucks up 2.4 with WiFi signals, but almost nothing sits in 900MHz, basically just some walkie-talkies and a few 90s wireless phones. Interference isn't as lethal with spread-spectrum, but it never hurts to be extra careful.

I feel like making an RC plane; I got a 3D printer, I got materials, I'm pretty confident I can get the mechanics and dynamics right, only the electronics are hazy to me.

What are the basic parts you need for controlling the whole thing and how do you tune them, any coding in Pi or Arduino or is it just wiring components?
Also, what does the whole electronics for a basic plane cost, china allowed.

Also, is (eventually) getting a live feed from the plane hard?

You need things like a Flight controller and and speed controller for the motor and then you wire up a receiver for radio link. If you want to add Video you just wire in the cam to a Video Transmitter.

You will need to have firmware for the flight controller but its mostly all plug and play.

You can get low priced ok stuff on Banggood. Many people get RC parts from that website.

[Anonymous No.1515434]

>>1515383
>Does /rcg/ approve of chink shit like aliexpress?

The overwhelming majority of the stuff we use in this hobby is designed, developed & manufactured in China, so buying from China (either direct from the manufacturers that have their own online stores, like T-Motor & Airbot, or from big warehouses like Banggood) is often actually the best idea.

Whilst some people will clamor that you should 'support your local hobby store', the unfortunate truth is that many (most?) local hobby stores are thoroughly stuck in the past & simply don't/can't keep up with the rate of change, especially in multirotors. It's depressingly common to hear reports from people that went to their local hobby store to pick up something simple like a flight controller & some props for a miniquad, only to find that all they had was an obsolete Naze32 for $50 & some glass fiber twinblade props from 5 years ago for $8 a pack.

That said, there are some decent online EU stockists, but they are almost exclusively newer outfits that have been set up in the last few years as multirotors really took off, rather than longer established physical hobby stores that have been catering to retired fixed wing enthusiasts for decades.

>And does the radio transceiver matter much (any things in specific I should watch for)?
>I assume that will be the most expensive component?

Buy a Taranis QX7, it may seem pricey as a beginner but it will be all you'll ever need for flying both planes & quads (& boats, tanks, cars, lawnmowers, whateverthefuck).

If you want to build a plane with a flight controller, go for a small/cheap/modern receiver like the R-XSR that just has a serial output with all the channels in it. If you want to build a simpler plane with no flight controller, you will need a receiver that actually has individual channel outputs to directly connect to your ESC(s)/servos, like the X4R (4 outputs) or X8R (8 outputs).

[Anonymous No.1515455]

I might be a retard but how's Banggood different from Aliexpress, I always assumed those were basically the same; different assortment?

[Anonymous No.1515457]

>>1515434
And for my understanding, flight controller means flying by code right? So for a starter I think a 'normal' receiver with separate outputs is better. Is that not possible with the QX7, because you say, get a X4R / X8R in that case?

[Anonymous No.1515469]

>>1515455
Aliexpress is a bunch of different retailers/companies (a bit like eBay or Amazon Marketplace), whilst Banggood is a single retailer.

FPV via phone goggles isn't really possible because there is too much latency in the analogue-to-digital conversion to get the picture into the phone.

You can buy a cheap FPV headset for <$50. Only drawback is that they're quite bulky.

You can't really salvage a transmitter from a toy grade quad, but if you want to try the hobby for absolute bargain basement then the FS-i6 is really the cheapest radio worth buying.

I can incorporate a li-ion battery to get 50% longer flight times, but doing so will make the battery non-removeable. It's a fixed wing endurance UAV, so that means 6 hours of flight vs 4. Having trouble deciding which.

Thanks, that's much more useful information. Do you mean not removable in the field or not removable at all? You will probably be fine not being able to switch it out in the field since that is such a long flight time, but you might need to remove it at home if there's any problems.

I'll try to give you a serious response.

Firstly, what is the purpose of this gimbal? Is it for a video camera? An antenna tracker? Scientific apparatus?

And secondly, are you just building it for shits & giggles without too much concern for how it performs, or do you actually want it to perform well?

If you care about the results, there's simply no sense in building it yourself unless you have very unusual requirements - anything you build will cost more & perform worse.

If you don't really care about the results, google for 'brushless gimbal controller' & 'brushless gimbal motor' & you'll find the basic parts you need. Don't even think about using servos, unless you really just need very rudimentary, jerky motion.

Why are you even asking for advice if you're not actually going to consider the responses? Have you stopped to think that just maybe the people trying to help you have more knowledge/experience than you? That maybe your comparatively uninformed plans & assumptions might be faulty & you should maybe alter them, rather than attacking anybody that dares criticise them?

The simple truth is that making your own 'aerodynamic' gimbal for your endurance aircraft will almost certainly have a truly negligible effect (if any at all) compared to just using an off-the-shelf unit. In fact, making your own will probably have a negative effect as it's incredibly unlikely that anything you can DIY will weigh less than an off-the-shelf unit & even an increase of just a few grams will almost certainly more than cancel any gains you might have seen from improved aerodynamics.

Yes this is the /diy/ board, but that doesn't mean that we shouldn't be realistic & inform people when we think their plans are pointless or won't work. If you wanted to build it just for fun that would be another matter, but you're not; you want to build it under an obstinate ideal that it will produce a real & measurable improvement to your endurance, which we simply don't think is realistic.

At this stage I'd actually recommend that you start a thread on RCGroups; they love long, drawn-out debates about things like this which at best will produce truly negligible results. But I'd recommend you address your temper & curb your childish homophobic language first.

For aerodynamics a dome is the absolutely easiest way to do it, and the results aren't noticeably worse than actually making a form-fitting cowling. There's a reason all those military radar surveillance and whatever planes go for big domes instead of fitted cowlings around the discs. If you care that much about scratching the dome then just attach the dome to the pan platform, so it rotates with the camera. Then whenever you land rotate the dome so that the camera is facing rearwards, and you won't get any scratches on the part you use 90% of the time.

Making batteries a structural part of the aircraft would probably mean a compromise in terms of ability to swap batteries in the field, do maintenance, etc. Also, you reach a point of diminishing returns, where filling otherwise empty space (zero weight) with extra batteries (non zero weight) doesn't necessarily increase flight time.

>Is a pentacopter possible if the motors were arranged in the typical 2 motors balancing out the opposite 1?

The only pentacopter design I've actually seen done is a 'dragonfly'. It's logically the same as a tricopter - the front left two motors literally have their ESC signal wires spliced together, as do the front right two motors, so as far as the FC is concerned it _is_ a tricopter.

Guys, I want to build a drone that's capable of a very long flight time. Like hours. 24 hours would be cool but probably unrealistic without it being Xbox hueg.
I'd like it to be at max 4 feet wide x frame. But prefer like 2 feet. So fuel based is probably out.
I'm looking at electric motors but idk where to even start. It sounds inefficient to use DC motors and speed controls, but it would also add weight to have sizeable AC drives.
What's the most efficient way to do it?

The uav doesn't need to have a payload either, just GSM modem and maybe a small camera, but that's about it. But I need a very high flight time and to be able to control it from miles away over the internet.

If I were you I'd make a helium-filled blimp. Endurance heavier-than-air is significantly more difficult, but a blimp could easily carry enough batteries to do some light flying for several hours, and could be left to float for long periods as well to stretch that even further. Only problem is that it would quickly blow away if there's even a hint of wind, so you'd want to keep a close eye on the weather reports.

>Well this thing has been disrupting the airport for 12 hours, a quad lasts 15 minutes.

A single sighting for a few seconds is enough to shut down the airport for probably at least 30 minutes, maybe even an hour. The perpetrator doesn't need to keep the drone hovering over the runway permanently to keep planes grounded, they just need to fly it to the runway once an hour.

>They also can't find the operator, indicating long range.

The operator could just be somebody sat in a house or car, of which there are thousands within a few miles of the airport. It could literally be somebody launching the drone from the garden of their house a mile from the airport fence, telling it to fly a waypoint mission & then they immediately go back inside their house to play Fortnite for 20 minutes until it returns.

>>1520309

They just need to get seen once, for a few seconds, to shut down the runway for a long time. They just need to fly to the runway, hover around for a few seconds, then fly home to charge for an hour before doing it again.

>but surely they would have some way of watching where it goes when the battery needs changing

You're talking about something potentially the size of a shoebox, in a 40km square area, that can potentially move quite fast & of course can just climb up to a few thousand feet before returning to its home.

>I guess if it's modded then it'll have decent range, probably 6km on 5.8ghz with a decent line.

An unmodified DJI Lightbridge system (what stuff like the Mavic uses) can do 5-6km real world without any modification. And waypoint missions don't need a connection at all.

If you were there, chances are it would get sighted on the other side of the airport & by the time you'd relocated it'd be gone. This is kinda the whole reason why this debacle went on for as long as it did. A sighting of the drone at one side of the airport is kinda useless, because by the time people with race quads, guns, butterfly nets, etc. have relocated to that side of the airport... the person flying it has just climbed to 2000ft & flown 5km to the complete other side of the airport.

> The next thing you could do is jam the command signals controlling the drones. Is that doable? Yes. Practical? Not really. Fraught with danger? Oh yes. It's also illegal. No, really. Assuming the local police even have access to spectrum analysis equipment that allows them to find what frequency is being used to control the drone, they need legal permission to start broadcasting jamming signals. That said, maybe they do have spectrum analyser kit?

> Either way, the permission the plod need to jam the drones is something they simply don't have right now, as far as we're aware. You need to have authority under the Wireless Telegraphy Act to start broadcasting any kind of signal – even one intended to bring down a fleet of naughty drones.

No definite info either way that I've seen, and I doubt they'd make it public knowledge so copycats don't get any ideas, but I'd guess waypoints. Launch from location A, have it return to your predefined location B, if the location is not swarming with fuzz, recover, launch from B, set return location C, rinse repeat for maximum lulz.

The linked article does raise the possibility of using GPS jamming but cites public safety (drone could come down on a car/house/human or continue into the airport and hit/damage a stationary aircraft) as a reason not to do it. On balance it seems like an acceptable risk, especially if the quad could be captured and its home waypoint established, but again, UK.

> could they make the GPS satellites deny info to devices inside the airport?
This implies GPS signals can be beam focused, which by nature they cant. They need a wide spread of their signal so you get overlaps of coverage and the system can work.

This is nothing surprising. A single sighting of the drone near the runway for a few seconds will shut it down for 30-90 minutes as they investigate, it doesn't need to be hovering there the whole time.

>it sounds like they might be pretending to attempt to take it down, and trying to triangulate the guy instead

Highly unlikely to work - the drone could simply be flying an automatic waypoint mission with no actual connection to the operator at all.

There's no such thing as a directional GPS jammer.

By definition, a GPS receiver is looking at satellites on the horizon in every direction and fixing position based on multiple contacts.

Even when a GPS receiver has a directional antenna that only covers the horizon & upwards, if there is potentially multiple watts of 1.5GHz interference coming at it from the ground a few hundred metres below, it's not going to be able to distinguish the comparatively negligible power signal coming from the GPS satellites above.

There's a big, long (& IMO largely pointless) debate about this, with all sorts of people throwing around science they don't actually understand to 'prove' why you absolutely must use them... or why they absolutely make no difference.

I think it's fair to say that it *used* to be more important to have a ESC ground wire, nicely twisted with the ESC signal wire, simply because those wires used to be a lot longer (think ESCs at the end of 14" arms) & because the PDB/FC used to be less integrated (so the ground plane wasn't so small).

But with with today's miniquads where your ESC signal/ground wires are about 1" long & your FC/PDB are so compact that the 'power' ground & 'signal' ground pads are connected by literally just millimetres of copper trace, I think it's fair to say it's meaningless.

A decade ago people did use Arduinos as flight controllers - in fact the hugely popular & successful Ardupilot project, which today is pretty much the go-to platform for research purposes & larger scale DIY projects, started out life on the ATmega2560 (eg the Arduino Mega).

Today the scene has moved on from 8-bit ATmega microcontrollers & pretty much everything uses the 32-bit STM32 family of microcontrollers.

If you want to program a quad to 'do other things', the sensible approach would be to use an existing flight controller hardware/software solution & just extend/modify it to suit your needs. There is no point in you reinventing the wheel by writing basic flight control/PID stabilisation for a microcontroller... when it's already been done & perfected numerous times. Things like Arudpilot & Betaflight are open source & pretty much intended to be hacked & extended in this way.

Of course if you know how to write STM32 code you could start from scratch with any modern off-the-shelf flight controller, but it would literally take you years just to get the basics of flight working even half as well as the open source codebases that are already out there.

>I also have a 3d printer, are there good schematics for a quad.

3D printing is really only useful for accessories/camera mounts/antenna mounts/etc. None of the filaments that you can 3D print have the strength/rigidity to make them viable options for a multirotor frame - you're literally better off using wooden dowel, or just buying a $20 carbon fibre frame from China.

Successfully designing a decent shell style frame is way above the skills of most hobbyists.

I say this as somebody who owns a Prusa i3 mk3 so obviously supports 3D printing.
