Thanks for the response Dick!

I think I'll go with all four wing panels flat. Makes life easier and will match the current prototype anyhow. So any objections to going with a NACA 0013 for the wings?

I'd like to get this bird as light and aerobatic as possible. Shooting for 15.5lbs to 16lbs and a DA50 for power. I like to hover and other 3D stuff

So if I read your post correctly, no negative incidence is required on the top wing even though it is offset in front of the bottom (the three view shows about 2 deg of neg incidence by my estimation)? Also, thoughts on the elevator incidence (plan shows about 2.5 deg positive)?

Cheers,

John
