Most people are using analog fpv solutions for the phantom 2 and 3. a dji iosd mini, 200 or 600mw 5.8ghz transmitters, black pearl or white dwarf receiver / monitor combos, and a decent set of circular polarized antennas are my suggestions. some setups you can get premade cabling for, but I did it all myself the first time, and its trivial if you know how to solder. Its still going to approach $400 (unless you realllly cheap out with the receiver and antennas - cheapdrones has some options that I can't vouch for) moron izzard fucked around with this message at 20:44 on Jun 13, 2015 |

So I had my first minor crash. Was attempting to land LOS on a patch of grass about 30m long, with a slight wind from behind. Seems I needed 40m, as it was stopped abruptly by a concrete barrier before the grass could slow it down fully. Apparently I was coming in at 75km/h, despite no throttle. Likely only 10-15km/h when it hit. Bent the aluminum wing spare a bit, and a little bit of crush in the nose, but otherwise just fine. The battery on the other hand, not so much. The battery is cool, and all the cells are within 0.02 volts of each other. But I'm guessing the consensus would be the battery is just not worth risking? Kind of hate to toss a $60 battery, but then I'm flying around a $400 plane. Golluk fucked around with this message at 02:38 on Jun 14, 2015 |

Likely only 10-15km/h when it hit. If you were flying downwind when you landed, coming in at 75km/h isn't really that surprising. Always land going upwind if it is at all possible. Batteries should be fine as long as it's cool to the touch and doesn't get any bigger when you charge. Also watch the balance on it after every flight or two, but it sounds like you are doing that already.

I finished the video of the rally race some friends and I do in a farmer's field. All of the aerial footage is from my Blade 350 QX3 AP and the ground footage comes from an assortment of Go Pros (OG Hero to Hero 3+ Silver). I slapped it all together with iMovie. https://www.youtube.com/watch?v=FMhAnElQmgA

I have a few that look like that and they work fine.

So I had this happen on the weekend https://www.youtube.com/watch?v=I9KVdiZ4JWA Jump to 8mins for crash. Tip stalls really suck . Consensus seems to be my cg is a little too aft which is why the spin is so violent. I was flying with a strong tailwind so the 60kph groundspeed was with a much lower airspeed. Damage isn't that bad. I've already gorilla glued the nose back together and just need to make it pretty again.

More throttle and pulling up doesn't get you out of that?

Anti-spin controls are generally throttle to idle, rudder against spin, neutral elevator and aileron (depending on the aircraft/spin mode, anti-spin aileron can be either with-spin or opposite-spin). Once you pop out then it's just recover from the resulting very-nose-down attitude, but model aircraft are generally pretty low to the ground so recovery time is minimal. Plus ascertaining spin direction is probably pretty hard when all you have is FPV video and no real flight instruments to help you out. (or no FPV at all)

# ? Jun 18, 2015 00:32 |

The other problem with going full throttle to try and recover is if you don't recover you are just adding energy to the crash. I knew I wasn't getting out of it so I left the throttle cut but I didn't have time to stop the roll either. If I had thought in advance I might go into a spin I might have had a chance but it took me by surprise.

Golluk posted:More throttle and pulling up doesn't get you out of that? If you are thinking like a 3D plane getting out of it, it's a bit different because you have huge flying surfaces and a ridiculous thrust to weight ratio. Most planes do not have the rudder authority to just power out of a spin, it takes time to slow it down. Jets are the worst offenders here - it's bad news when any sort of stall happens. subx fucked around with this message at 14:35 on Jun 18, 2015 |

subx posted:If you are thinking like a 3D plane getting out of it, it's a bit different because you have huge flying surfaces and a ridiculous thrust to weight ratio. Yeah, jets are really highly loaded and also really really dense compared to civilian airplanes so they spin flatter and faster. The 140 I got my private license in would come out with just neutral controls, but the T-45 requires anti-spin inputs if you're so unlucky/bad as to get yourself into a sustained steady-state spin. If you catch it early during the departure or incipient spin phases neutral controls will save you though. Also it spins inverted, so there's that. It's kinda off-topic for the RC thread but stalls/spins/out-of-control flight is something I find really interesting, so, yeah.

Hold onto your butts... Everyones favorite senator, Feinstein just introduced this bill. It's a doozy. Here are some of my favorite parts:quote:—The final rule required by sub-6 section (a) shall apply to consumer drones that— The final rule will include: quote:(1) limitations on altitude for consumer drones, whether through software or other technological means; But here is my ABSOLUTE FAVORITE PART: quote:(1) IN GENERAL.—The final rule required by subsection (a) shall require modification, at the manufacturer’s expense, of any consumer drone that was commercially distributed before the publication of the rule so that, to the greatest extent practicable, such consumer drones meet the requirements prescribed under the rule. The manufacturers will have to upgrade current drones.

is there any way to downgrade a taranis receiver (specifically a d4r-ii) back to the 18ms version? I don't need a full 8 channels (and even if I did, its trivial to set up channel 5-8 resolutions so that it doesn't gently caress up the signal if they are all used)

Because that would be a higher refresh rate (55.5 hz vs 37)? Unless I'm mistaken, the only real issue was with all 8 channels used, so if I resolved that, why wouldn't I want to be sending more inputs per second? Same as with higher refresh usb keyboards and mice. edit: found the d4r thread on rcgroups, someone found it 2 weeks ago.

I don't really get why someone would need 8 channels for a mini anyway. I use 4 control, one for arming and one for LEDs off/buzzer on. I guess if you used self level modes that would be an extra channel.

I finally had some luck with my mini quad. It is now up and flying very smooth, but needs some pitch/roll mixing because of the asymetrical layout. It wouldn't fly before because the board thought it was upside down. The entire frame is 3d printed, even the spacers. Fell in love with the Dremel blue and now I'm paying out the rear end for brand name filament. It is a very nice blue and does cool things in the sun, photos do not do it justice. I completely redesigned the frame enlarging it from 125mm to 140mm, 3020 props, and switched from individual ESCs to a 4-in-1 board from Ready to Fly Quads. Everything fits so much better. The arm supports make the frame very rigid. The next step
