Ahhh, ok, that explains it, as you already figured out, your flaring technique is whats doing it, you have to let off the elevator just before it touches that tall grass your flying in, there is nothing wrong with the aircraft design, same for the ailerons, with the hundreds++ of these out there I have also never had a compaint on the aileron hinging. This includes my own being thrashed and other locals Ive seen fly and crash them hard..

Have fun!
