Hello, I read somewhere were the TE of the control surfaces should be squared off. The "rounded off" TE creates some kind of turbulance that helps create flutter, and eventual failure of that surface. I have started my Sig 4* 120 and it has 3/8" thick control surfaces. They say to: sand angles on the LE for the hinge movement..... and ROUND OFF the trailing edges of all control surfaces. What do you experienced builders out there think???
PS. These ailerons have NO taper anyway, and look like a block of balsa hanging on the wing etc.
While I have your attention.... .... I read somewhere about a "trick, or jig", to sand and
even taper down the length of control surfaces. Anybody familar with that?
Thanks in advance.... lownslo....
