I want to buid a wing that can do some snaps AND harriers AND elevators... I know that these maneuvers are requesting very opossite characteristics on the wing. I´m planning to use an E169 in the root and a fun fly airfoil on the tip to include some taper planform, but how much? pattern planes have about 55-60% of taper, I want to use less than that to improve stalled flight .... any suggestions?
