Crash + AUTO mode heading down instead of up

Stabilized mode was working really well, so i decided to switch to auto mode to see what would happen. I gained 100 meters of altitude and once in auto mode, the plane started to lose altitude…Continue

It took 4 days of painful work, but i finally got there. I consider this the base for my UAV experience. The transmission is incredibly stable, the video is really smooth. Here is what i…Continue

"I think that you should keep it simple, and photovoltaic adds a big and useless layer of complexity. You need panels, transformers, possibly a MPPT, etc. Batteries are much easier, especially at this stage and especially if you can only lift 3kg.…"

"I made some calculations in the past and realised that due to the huge volume of the blimp you wouldn't be able to manovrate it using photovoltaic panels in any basically any wind condition at all.If you found different results, go ahead with…"

"Can't the APM automatically correct it's barometric height using the one provided by the GPS? You should obtain a pretty accurate reading."

"You did mention that loiter works, however i will recommend that you verify your motors + props are correctly setup. While on the ground and armed, try a little roll right, the left of the copter should lift just a bit. Repeat in reverse for roll…"

"I just wanted to thanks everyone for their answers, i'm still unable to lift in stabilised mode (it seems unstable and i don't trust it), but loiter mode works perfectly. I can takeoff without any problem. I already had my first crash…"

"Check the wiki and the manual. It's pretty well written with a lot of good info. ESC calibration is to tell the ESC the range on the throttle. Where min and max are. If the DJI can't be calibrated, then maybe you need to replace them. Also…"

[newbie] Can't even lift and i'm not sure if the setup is correct

I've made a little video explaining my problems, it looked like the most direct way of explaining them to me.http://youtu.be/Rj3oAEUDLBg In short, apart from the fact that i had my pusher and normal prop inverted (and thus i wasn't able to lift), with the throttle lowered at the minimum spinning speed, some of the props are stopped. Trying to tilt the copter doesn't create a behaviour that makes sense to me. The accelerometer of the APM is perfectly…See More
