Would it be irresponsible to use a drone on a waypoint/flight path based system totally unattended? Say, set a flight path above a race track while me and my buddies do laps? It'd be flying either around the outskirts or just sorta floating and rotating above the infield so if it had a failure and decided to drop like a stone it shouldnt land on the track. right?

Obviously I'd clear it with the operators first, I was more thinking of the 'drone etiquette' perspective. I mean, a RTF unit like the Hubsan X4 pro or a DJI is reasonably reliable for semi-autonomous flight, yeah?

Laserface posted:Would it be irresponsible to use a drone on a waypoint/flight path based system totally unattended? Yes, 100% irresponsible. There is all kinds of poo poo that could very plausibly go wrong and cause an unsafe situation. Battery runs low and aircraft decides to RTH, only now there is a person/car/dog/whatever where you took off. Compass gets hosed up and aircraft toilette bowls into the track. Cloud cover+flight path puts the aircraft in an area where GPS reception is poor and it wanders way off course. Some idiot cowboy in a 172 decides to buzz where you are flying and doesn't see your aircraft. These are all things that have happened to me while flying. All of them could have or would have been unsafe and possibly caused injury or property damage if I didn't have the transmitter. Neither the general public nor the flight controllers in our aircraft are smart enough to make this a safe proposition yet.

The Hubsan certainly can. But with DJI I'd want to check if your location has been added to the do-not-fly list. Is your track within 10km of any airports? I've a CX-20 arriving soon and apparantly I haven't spent enough money yet so I'm looking at camera/gimbals. http://www.banggood.com/FPV-14-Sony-700TVL-HD-Zoom-Camera-For-1_2G5_8G-Telemetry-p-935033.html Does anyone make gimbals for formfactors other than gopro/ilook?

My Calypso's fuselage has been ripped in half multiple times now, and I think it's more Gorilla Glue than foam now. Why yes, my trim settings are all weird to keep it flying straight.

My Calypso's fuselage has been ripped in half multiple times now, and I think it's more Gorilla Glue than foam now. Yeah, have at look at Mister Sineway and my selves pictures of our Bixlers (Page 69). We punished them hard, glue em back together, and punished them more. Hell, you hit a tree (I've hit/landed in 3) which is somewhat soft. I've tried a loop from too low and flew into the ground at a 45 angle. Wing mounts broke off many, many times. I think I've glued the front nose on from breaks like yours about 7 times. As was noted, Gorilla expanding foam glue is great for fixing EPO foam planes. Get some pins/needles to hold the parts together while they dry. Small clamps with paper between them and the plane as are handy while it dries. That plane has plenty of life left in it. I have OpenTx on my 9x. It was well worth the time to get it on the radio compared to the stock firmware, and I believe I just followed the same instructions (Most likely the same/similar chip). The Frysky stuff is pretty solid. Though I use OrangeRx DSMX (Cheap, but haven't had an issue while flying) and DTF UHF Tx/Rx modules. I don't think I've ever accidentally done a loop, so I suspect the throw on your elevator might be a bit high. Try moving it down/up a hole so its closer to the elevator. It will give you finer control. As you found on your 3rd attempt, Mister Sinewave and myself also made the same mistake, and tried to flow low and slow. Which is a terrible idea as its practically a stunt move. Give it lots of throttle, and get it up 75' or so. You want lots of time to recover, but still low enough to clearly see the plane. Drop the throttle back to about 50%, then start banking it over about 25-30 degrees, and giving it a bit of up elevator to turn in a nice circle. You can pretty much ignore the rudder, Bank and up to turn for now. At some point, you should try and get it flying straight and level. Use the buttons around the sticks to adjust the trim so it flies level on its own. Once that's done, you'll want to start practicing landing. Basically try to land on a virtual ground 40' up from where you will be landing. The easiest is to reduce throttle (if its cruising at 50%, cut back to 20%), and aim it down enough to keep its speed up (~5-10 degrees). Once you get 3-5' above your virtual runway, pull up gently so its flying level. The plane will start to slow down and descend on its own. Once you "land", or mess up and stall, bring the throttle back up to 75%, and try and again. Once that's comfortable, or your battery is getting low, try it for real. Once it's back on the ground, see where the control surfaces are (ailerons, rudder, elevator), then set your trims back to 0. Then physically trim the plane with control rods so they match what you had trimmed to in the radio. Regarding wind. It's best avoided before you have the plane trimmed, and some comfort in recovering. Wind near the ground can be very sporadic, and a real pain to fly in. The flight stabilized receivers make it a lot easier to fly in, and make up a bit for bad trims. Just make sure they are actually responding correctly, or it will be looping/rolling like mad. Positive feedback loops are bad when stabilizing. Golluk fucked around with this message at 04:57 on Apr 21, 2015 |

Does anyone know what languages the APM flight controller uses? I heard it's neither BASIC nor HTML, which are the only things I (can pretend to) know. Is it C? C++? LISP? People say, "learn java because it's easy," but I'd never use it so there's no incentive. But being able to program a flight drone might be incentive enough. Any ideas what languages they use?

It is probably the form of C that arduino's use. Unless you are planning on rolling your own flight controller code it is irrelevant. You dont need to know any programming language to setup an APM.

Oh. That was easy I guess. I just thought about how computers were in the mid-90's where you couldn't just plug in a mouse and expect it to work without restarting vs. today where you can plug in a web-cam, take a picture, then put it on a usb stick. Attaching telemetry and sensors doesn't require coding? I'm really, genuinely curious how a drone knows "these wires are a GPS" and "these wires go to motors." If "how computers learn vestibular & kinesthetic senses" is taught in middle school, I'm sorry. But when I was a kid you only needed to know Wheels, Wedges, Pulleys, and Screws. Electricity was a "thing" that "other people" "did". So, I'm not up to date. Sorry. Like, humans are really able to synergize senses. Everyone knows about the Vestibulo Ocular-reflex. But we can do more poo poo like duct taping motors to ourselves to know where we're going. This is just a side-effect of our somatic sense interacting with said vestibular and kinesthetic senses and some Very Clever Software. But as far as I knew only humans contained said Very Clever Software. Can we just strap poo poo to drones and they'll know what to do with it? I didn't know we had Self-Learning AIs yet. poo poo. Edit: I look at flying like this and wonder how one's drone knows whether it's got one of these in it. DreadLlama fucked around with this message at 05:16 on Apr 23, 2015 |

To be fair the firmware does require coding to read those sensors, but you dont have to necessarily program it yourself (unless you are making your own as stated). the sensors usually just show varying resistance or signal which is then interpreted as a raw value by the firmware, and then the software layer allows you to calibrate or adjust how those inputs are read. the raw value from sensor X is Y, and by changing the weight of those values you change how the system reacts to those inputs.

You probably know all this already by now, but new people should also find it useful. All of these items are required for the drone to fly (except GPS, but if you are building a drone you should include a goddamn gps for your $500+ drone so it can return to you upon signal failure or other poo poo instead of crashing).

There's also the "Give DJI $1200, they give you a charge-and-fly GPS enabled camera-carrying drone" method. If you can build a computer from parts, know some basic electrical theory, and can solder, you're 90% of the way there. Some basic aerodynamics knowledge will save you some time, and possibly some parts, but it's not critical. The flight controller is basically a magic brain box that makes quadcopter flight possible.

Yep, all of your questions are answered by the flight controller. It does literally have ESC ports, transmitter ports, GPS ports, all that jazz. It doesn't have to do any sort of "oh god what is this let me do learning" because the nerd who programmed/built/sold the flight controller did all that. I imagine there are industry standards about the communications protocols, but you don't need to know any of that crap to put these together.

I was browsing the FPVLab ground station thread, and decided I wanted to go the tripod route. I was using a fanny pack to hold a battery, RX, and DVR, but it wasn't going to work as well with diversity. I also wanted to get my body away from the antennae. So after a night and a morning, I threw this together.  Closer inspection will reveal many not perfectly square or flush edges, and a fair bit of hot glue constructing. But the load bearing stuff is solid, looks OK from a distance, is easy to move, and gets the antennae up about head level if I'm standing. Just need to track down some RCA adapters (male-male), and slapping a voltmeter on the battery. Might look into a small monitor for any curious visitors.

What is the point of those big canon looking antennas? Or a "diversity" antenna in general? Is it for planes flying very high and very far, or would you us this setup for a little 250mm racing quad too? Do diversity antennas take in ALL radio frequencies? Why would it do that if your TX is only sending one type of signal? I just don't get the concept behind them.

That looks really cool. I actually took a similar approach with my FPV monitor, I stuck it along with all the RX crap onto a cheap tripod. That way I can just plant it and set it at a comfy height and orientation instead of fiddling with it stuck on my radio. And striding sunset robot: the point is that diversity on the video receiver end allows the receiver to use whichever antenna is getting the strongest signal. The cannon-looking antenna is a directional antenna (long 'range' but only in a tight cone, must be pointed at the transmitter) and the mushroom looking one is the usual CP most of us are familiar with (omnidirectional as opposed to the highly directional tube-looking one). The transmitting end doesn't need to be any different.

Got out for a bit this afternoon to try out FR632 diversity VRx, Aomway 200mw VTx, Sony super HAD II camera, and Mobius. I must have been feeling brave since there was enough wind to knock over my ground station as I was setting up the plane. But then flying in one spot like its a quad is amusing. Sadly the manual settings for the camera at 1/60 shutter speed meant a complete whiteout, which seemed to mess with the DVR (I think it was having trouble telling NTSC from PAL), so it ended up just being a LOS test of the Mobius, and if RTH/Hold was working any better with telemetry off. Pretty happy with the Mobius.  https://www.youtube.com/watch?v=Fceue04O7NI RTH and Hold seems to have some issues with high winds for some reason though.
