I have noticed that the port aileron counterbalance actually comes in contact with the upper and lower skin and is not quite allowing the down movement to reach the appropriate degree. Both peak loads and flutter risk will be reduced. Password. Most of the holes are #40, but the bottom fasteners attaching the skins to the spar will be pop-rivets . Counterbalance is key in the precision flying required for aerobatics. The skin should sit on the spar, however if you c'sink to the point where the dimpled skin sits flush on the spar, the spar will have been reamed out too far and the rivets/clecos will barely fit. Machining carbon fiber can always prove to be challenging as it doesn't machine like metal. Do we need to move the CG of the elevator all the way to hinge line?
