during auto takeoff I suffer from unintended yaw direction changes which leads sometimes leaving the runway. I even added a second external compass because I was suspecting issues due to location of the first close to servos.
How can I find out what causes this behaviour?
Attached please find a log with three takeoffs: Yaw Problem during Autotakeoff
I thought I was having this issue also, but it was my prop. my Volantex Ranger EX is a pusher plane and it came with a tractor prop. It made it pull to the right at full throttle. With a tractor prop it holds a nice straight heading on takeoff.
