Status: offline 		Wash-out is warping the wing to reduce angle of attack at the wingtip... you move the TE up. The purpose is to make the tip stall later than the root, helping prevent undesired spins.

On a 1/12 scale combat plane... minor wash-out to NO wash-out. Wash-out inherantly reduces maneuverability. I'd go with 1/8 inch to 1/2 inch MAX on a 48 inch span combat plane. You'll probably find you wish you hadn't put in the washout...

You can simply put a slight twist in the full span aileron typical of the R/C combat models. Its easier to adjust the twist in the aileron than the twist in the main wig panel. You get the same effect when dealing with small amounts of washout.

I sometimes use WASH-IN (opposite of washout... enhances ability to enter a spin) on my combat models.
