I tried the flaperons on my rocket and it does not seem to like it. When you land the plane are you using throttle to control alttitude and elevator to control speed? I have not had a problem with stalling my rocket, in fact, even at idle with 14x6 prop I can land fine. Try experimenting with stall speed and a higher alttitude to see how slow you can fly it. Another to remember is smothe on the elevator, I get really good control response all the way to the ground and it is easy to "pull up" when the ground is comming and stall the wing causing it to drop the nose slightly and "bounce" off the ground and back up into the air. The actuall "stall", on my plane, is so mild it can easily be missed and dismissed as over control?
