I found this discussion after research because I encountered exactly the same Flueter problem! I bought a Kitfox3 that was stuck more. The son of the former owner who is an instructor tells me that the plane flew in the state but he is not honest, I think. I took all the games in the flaperon control and Kitfox sent me the technical data sheet with the set of 1 to get.When I checked this week, we found a significant difference from the good In the neutral position, we have more 3 "instead of 1. Photos Below I think this may be the cause of the problem of flueter What do you think?
Thank you for your help.

Actual neutral position with 3"

Réglage des flaperons selon les valeurs préconisés par Kitfox. Dans cette position des flaperons, le levier des volets est tirés
de 17° donc en position neutre les flaperons se retrouvent en négatif de 17°!! (Raison du flueter???)
