My RV-4 has a heavy wing. The problem is, I’m not sure which it is. In level flight, the ailerons deflect themselves slightly, with the right deflected up and the left down. If I release the stick, they maintain this position and the aircraft predictably enters a slow right roll. If I use my Mk I eyeball and align the trailing edges of both ailerons with the flaps, the plane enters a left roll, with a faster rate than the stick free right roll.
Is this a heavy right wing or a heavy left wing? I’m trying to narrow down where to look next.
For background, I have already verified that the flaps retract fully, and the trailing edges of the ailerons align with the flap TE with stick neutral on the ground. The right wing tip TE is slightly out of alignment with the aileron, but what I’ve seen on here has differing accounts on if this has any effect. The ailerons deflect in flight regardless of if gear fairings are installed, so I don’t think fairing alignment is the (primary) cause.
