I have found that you have to have the belt tension pretty tight to keep the blades from coming out of phase. And the blades them selves should be snug to the point that they don't move if you tilt the heli on its side but you can still grab them and move them with your hand. It can be alittle tricky getting the belt tight enough but not too tight as to cause premature bearing failure.
