Hi Krossk

What I was told my a few builders was that I must be aware of , flutter , as a mechanic it would be called a differetial in air flow going over the wing . It makes sence to me , so what I did was add 1/16 ply cross wise to the ailerons . It gave the ailerons strength and evened out the air flow over the wing . At least this is what I ve been showen . It will work out better when I sand down the wing .

Take care
