Today I flew my X8 wing in manual mode to get it perfect trimmed (done). It was flying like a dream. My second step was to change to stabilized mode, but when I switched I noted that plane did not keep level and right wing dropped drastically getting into stall. No time to recovered and it crashed.
Even if I followed ground calibration as recommended, something was wrong. Now my main doubt is about level calibration. It was no clear how to do it ( 1 axis ? , 6 axis ? just one time or every time before a fly ? How critical is it for stabilized mode? Is there a clear and easy procedure to follow?
I was using APM 2.6 , airspeed sensor, 3DR telemetry, 3DR power mod, latest arduplane firmware...
Attached is tlog file ( valid data after 60% of time scale).
Comments are welcome.
