well......I did the same thing in the cap. But i put a 46fx in it with a 11x4 prop. Tons better and easyer to hover and 3d. the 12x4 slow's it down a little but still easyer to hover. Here's the kicker.....i built a cap 232 gp and put a 61fx in it. Guess what???? It hoverd like the sim!!!!!! If i build another on better bet that i will put a 50 or 53 in it. To a point its pretty close to the real thing.
