My copter Crash during take-off :
I don't understand what's happen.
Here is my log : https://drive.google.com/open?id=0B8wk6B6h03C4V2lqdHBPZFROc2s
I have calibrate esc (Racerstar RS20Ax4 V2 Blheli, configure in D-Shot by default), I have calibrate compass and accelerometre, and I have calibrate my tunigy 9xr all with mission planner.
I have verify the sense of motor (with mission planner) and the sense of propeller :
Here is the video : Test sense of motor
I have succefful manually upload arducopter 3.5.1 (with px4uploader.exe and CMD). I have take copter-3.5.1_V2 firmware (because install directly with mission planner does not work).
Any know how is wrong with my setup ?
Many thanks in advance, if i find nothink, i try to mount an old crius with multiwii for test.
