As Mark L has mentioned, the bent spars offer many advantages and one that really interests me is a flap that starts at the fuselage and extends outboard of the stub wing. This creates the potential for some very effective flaps.
As I don't yet own a set of plans, I'm uncertain of the rear spar WAF junction and how one would hinge the flap. I assume the rear spar sweeps forward at the WAF, which creates a discontinuity for a hinge line. How would you guys do it?
