I have an application where it is desired that the plane stays level in auto flight. It should turn with the rudder and not bank at all.
ArduPlane currently cannot do that. It uses ailerons as primary heading change control and the rudder is used at most for achieving coordinated turns, where local lateral acceleration is zero. This is normally done for occupant comfort but hmmm it's a UAV.
Has anybody ever tried to write such a controller, or is anybody else interested in having one?
I can see the L1 controller does have some functionality to hold a heading with the rudder - for when rolling on the ground. Maybe this could be rewritten into flying towards a point instead of just keeping a direction.
Is there a presentation of how the L1 controller works somewhere? Maybe even the APM implementation?
