I've got an RV3 empennage here that I'm considering using on an original design. Whoever built it skinned the elevators and rudder with .020 instead of .016. Best I can calculate it, that adds about 5 ounces to each elevator, near all of it behind the hinge line. The elevators weigh L 4# 2oz(trim tab), R 3# 12oz. I haven't figured the rudder yet. The HS and Vertical are to plans...032 skin. The new design will be slower that the 3...cruise maybe 150 and Vne not far above that. The obvious concern is the possibility of flutter.
Is there any history/experience of the 3 with 020 control surfaces?
Thanks
