RE: Sig Cap 231 : what engine: IMAC
FBaity:
Did you flutter the aileron servos?
Were they installed according to Sig's directions mounted on those lite-ply covers provided in the kit?
I'll guess the answers are yes. Sig's method for servo mounting is the cause of the flutter, not your choice of servos. I'm using 42 oz-in Futaba servos mounted on bass wood rails - no flutter.
