Hi Folks
I am new to flight controllers, so hopefully, this difficulty is just lack of experience.
I am setting up a Pixhawk 2.1 in a fuel powered traditional helicopter.
Ardupilot - Traditional Helicopter - Preflight Testing, last point says (for stabillize mode) "Rotate helicopter slowly, in a certain direction the rudder stays in the middle" - Thus it should behave like a "tail gyro" & keep the machine on the same heading unless corrected by a stick input.
When I set up the FC on the bench, the "tail rate" outputs a tail correction when the FC is turned quickly, then returns to center as it should. However the "heading hold" that only centers the tail when the FC is pointed in a certain direction, only decides to start working now & then (mostly not).
I have set up previously with Pixhawk1 & now with a new Pixhawk2 & new "Here" GPS. In Both setups The intermittent "heading hold" occurs so I assume it is not an issue with particular FC or GPS.
Any help would be gratefully recieved
Regards
Simon
