RE: nexstar wing tip extensions
Big Air
The CAP tip stalls easily because it was designed to do so. Crisp spins and snaps require the ability to stall abruptly. Result of thin airfoil, relatively sharp leading edge, tapered wings, higher wing loading. Forget about adding things to this plane. If you want to avoid tip stalls:
1. Make it more nose heavy than recomended. This reduces pitch sensativity by increasing pitch stability.
2. Decrease the elevator throw untill it is not enough to cause a stall.
That's all there is too it. If your radio has dual rates, you can set low elevator so the plane can't stall, and the high so it will.
