How are you guys doing,

Has anybody installed the direct drive tail besides 91talonawd. I was just curious how hard the install was and does it really make a big diffrence. I am considering this mod but am not sure how much of a difference it would make and also i would have to rebalance it. Does using lipos make any difference when playing with the tail rotor to possibly counteractbalance the main motor.

Also does anybody now the exact allen size of the main grips allen head screw i cant seem to figure it out.

Thanks Scott
