Hi Vince I would get out the monocote and go to town on her! but If I understood you right you are going to fiber glass and paint her right! I know expert on that type of finish and if my memory serves me right by the time you get it down its going to be a very heavy model. Is there some kind of actuator where the drive shafts hook up to the ailerons? I see the slots you made but didn't see what the drive shafts connect to .
Thank You
