Hope someone can offer advice.
Recently repaired my Tiltrotor VTOL (Pixhawk 2.1) after a bad crash where I switched from Qstabilise to manual accidentally and I was too close to the ground.
Anyway it used to fly fine apart from a slight yaw oscillation in Qstab which I was ok with.
I’ve tidied the internal wiring and repaired but I’m getting some strange behaviour.
I successfully took off in QSTAB the transitioned to FBWA but I was fighting to keep the plane in the air. The throttle seemed restricted in some way and I couldn’t maintain altitude. Quickly switched back to QSTAB and landed.
Then I decided to hover and test QRTL - it rolled to one side and looked like it was going into a toilet bowl situation but i didn’t wait to find out and switched back to QSTAB in time to recover.
I’ve got the Dataflash log and telemetry log and there appears to be a number of errors namely “EKF yaw reset”, “error pos horiz variance” and “error compass variance”.
I would like to interrogate these logs to diagnose the issues but I have no idea where to start.
Could anyone give me some pointers about what to look for in the logs?
