My tail motor housing that goes onto the end of the tail boom is starting to rotate a lot. I mean the entire motor and tail blade and tail motor mount rotate around the tail boom. It being able to rotate is great while I'm learning, saved me many a tail blade and all. But my questions is, is there a way to stop the tail motor/blade from rotating SO much but still let it be able to move some. I don't want to CA the whole thing in place quite yet since I'm still learning, just need a way to tighten it all up. Thanks.
