I recently had a very bad crash with my quadcopter (pilot error) which had previously been flying well. Ever since the crash (and repair), I have been unable to take off. I experience a flip to one side or another on takeoff.
I am running an APM 2.6 with Arducopter 3.2.1.
I would appreciate any tips on what to look for, how to analyze the log, etc. Here is what I have checked:
* Motors are spinning in proper direction
* Props are mounted correctly (cw / ccw)
* Re-calibrated the Accelerator
* Recalibrated ESC
* Even tried reflashing firmware and starting all over from the beginning
* All connections seem solid
* Radio signals are being received correctly (radio test)
As a test last night, I powered on quad, brought up throttle slowly until it was just about to take off -- everything seemed fine, pushed the throttle a bit, and the quad went in the air about 2 meters, dipped to the front and left (#3 arm went low -- fyi, this is the same arm that broke off previously). Quad did half flip and landed on it's back breaking two props on the way.
Thanks in advance for any help. If there are log experts out there, I can upload for analysis.
