I won't forget. Of course, I don't think you would let me forget either.
The vertical "looks" a bit small, but there's plenty. The vertical tail coeeficient is definitely good. Letting go of the sticks in a spin, it stops immediately.
I don't know about different wing sets yet. I dropped interchangable wings in the design process early on, but I could look at it again in the future.
The stringers definitely help the wing keep its shape much better than the Dandy/SB.
I will try to get some video this week. We got some with Doug, but the overcast + drizzling rain caused problems with focus... It was out of focus most of the time.
