Standard servos barely fit in these wings. The plywood bed is really close to the rib profile(s) it is mounted between. When the covering is shrunk on the top side of the wing it is going to come dangerously close to touching the bottom of the servo bed (this pictureis the under side of the lower wing, Iam talking about the top or the wingor other side of this servo bed detail). This reminds me that Ineed to sheet over the servoarm,looks like Ikind of forgot thatdetail. The aerilon does not look as bad as the cross section on the plans makes it look.
