Both good comments. I agree 100%. Washout really can help cut down on stall problems and you can do it with the monokote on a built up wing. You just twist the wingtip downward a little towards the leading edge and then tighten up wrinkles in the monokote while your helper holds the twist in the wing. Trick is to get both wings right,,, and just alike.

Doesnt take but just a tiny bit... Im oversimplifying it a bit. I would do it the first time with someone who has done it before. Once you have seen it done its a snap, no pun intended!

Caviot; trainers have it built in, I have never seen one that needed it unless the wing is warped.
