I'd leave it as is. If you wanted an aileron plane, there are plenty on the market in all shapes and sizes. The Neofun is designed to fly without ailerons, so at least give it a try before doing anything to it. It won't handle wind for beans but that's the sacrifice you make. The Avistar is (IMO) the best 4 ch trainer on the market, especially in windy conditions. If that's what you want, then that's the one to go back to.
