world models clipped wing cub,my first build in many a year.The problem i have is that the jr servo 537 is to short for the cut out in the wing only two fixing holes sit over the balsa of the wing,do i glue a piece in or put a plate under the servo, which would raise it up maybe to much? any ideas would be most welcome,

Glue another stick across the opening so that the servo fits snug--an easy fix!!!

Glue a piece of ply under the opening, and then fill in the gap with balsa that is the same thickness as the wing sheeting
