Is the boom aluminum painted or carbon fiber wrapped aluminum? Carbon fiber is stretched.

If it is truly stretched then main blades will not even come close to being over top of the tail blades untill you get to about 785mm blades. On a non stretch about 715's are just at the edge of the tail rotor. If you have 730's on a stock boom then you blades will pass over the tail rotor a little.
