I built a .40 cap 232 and i put a 61fx in it. I think it would have been better with the 46. The tork roll was too fast and it was a little too hard to hold in a hover. Besides.....Im trying to take wieght out of it not put it in. Ive seen 50sx hover 6lb sig se so i dont think power is gonna be an issue. I just hope i can get the cg back far enough without it getting wierd. You know for 3D.
