I built a Quadplane based on the Fx-79 delta wing. In QHOVER mode it takes off and flies pretty well, but when the transition to fixed-wing finishes the plane starts to oscillate pitch increasingly (I have to come back to QHOVER mode to avoid crashing).
I thought it might be a gains problem, but I wouldn't like to try an autotune without being sure of the presence of other misconfigurations.
My current gains for pitch are
I'm sharing a couple of flights where the oscillation is noticeable (parameters and logs included).
Any advice to address the problem?
