It is also possible to cause stability problems. Over stable can make the wing spiral down if it is yawed too much. Especially if it is a poly where you are using the rudder as primary roll control and more likely ot apply a lot of it.
How do I know. I've done it. Nasty, nasty tip stall like behavior with the plane spiralling around a wingtip. Oddly enough, I believe I solved the problem by reducing rudder throw. Go figure...
