Hey,
Just wondering how much washout is in a 60" wingspan trainer, maybe a rough range??? How do you go about putting washout into a wing? Im scratch building a trainer and am wondering how much washout i rly need, and where do you want to place the piece of wood under the wing, etc....??? Any help with this would be great! Also any articles, websites, etc...that might have more information on this could help as well. Im guessing that a 1/8" piece of balsa would work, or a 1/4", thats about as much as i know on this. Please help
Thanks in advance

If it's a constant-chord wing, you don't really
need any washout, since aerodynamically the wing is effectively washed out by the way it affects the upwash along the span. If you don't like this opinion, I sure you will see others, but this is just MY philosophy. If I was building a trainer, I wouldn't use any, even a basic trainer that I was going to teach with.
