I am pretty new to all this, so please don’t hesitate even the stupidest mistakes. What are the steps to troubleshoot?
oh, and before you point me at the other topics on the forum, I did search, and I found this Plane will not stay on runway during autonomous takeoff but it is for PX4 and and they didn’t really resolve the issue there either.
Tell us about the plane. Single or twin. Gas or electric. Nose wheel or tail wheel. Does the wheel have steering or is reliant on rudder? What is the tail configuration of the plane? What kind of flight controller are you using? What firmware version? Are you using a compass? Do you have a .bin log file from an attempt? Auto mode or FBWA?
