I can not seem to understand what is happening here and I thought I would reach out for some assistance.
After flying in stabilization mode for about 5-15 seconds the quad will slowly start to pitch harder and harder to the aft of quad. I fight it with the RC stick controls but eventually the pitch compensation is not enough and I have to land, it happens quick, I haven't had a flight last more than 1min. It is almost like the craft if trying to compensate for something and is slowly learning to apply more pitch to the aft of the craft.
After landing, power cycling, then taking off again the craft works for a minute then starts to pitch aft.
I am running the latest stable 3.1 firmware and Mission Planner. I have done a compass and accel calibration, Mission Planner indicates proper axis control when I move the craft while plugged into USB.
Prior to flashing the firmware I did an erase, reset, and radio command to start fresh.
What am I missing? I am going to try a telemetry flight and record the details to post.
PS. I do not have anything covering the barometer right night now, but I didn't think this was an issue unless I was trying to do Alt. Hold.
