I note from pre threads on servos types that 8411 is the best ailerons, i am in the process of building one of these fine kits ,but after a lot of head scratching and studying David Gladwin
pictures in his review in jet int, i cannot see how these will go in without opening the servo boxes up ,or mounting to blocks outside the box and fixing permantly to the skin

,
there must be a way of making these fit any ideas,just before i dive in with the razor saw!
