Crash + AUTO mode heading down instead of up

Started this discussion. Last reply by cedivad Aug 1, 2013. 4 Replies

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

"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…"

"DJI OPTO ESC's cannot be calibrated, if it will not lift off I believe there is some basic configuration errors have snuck into the build. Cedivad, when the props are rotating, is there air coming off your props that is blowing your…"

"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…"

"Friend of mine had a similar problem and it was corrected by turning the receiver...making it face the front of the aircraft.  Don't know if this will help???"

"Those stock DJI ESC can't be calibrated, and the APM is a new one with no special parameters/just flashed with the last firmware. I had my props inverted and I fixed that, but I'm still unsure about the motors non spinning when the copter…"

"Did calibrate your ESCs? Sometimes erase and reload and recalibrate helps clear things up."

[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

"Because the h264 encoded stream is at a constant bitrate of (around) 4Mbps, indipendently from the resolution. It must be some kind of proprietary protocol that. Skype is able to decode it, but i have no idea on where to start to do the same."
