That Evo .46 is more than capable of turning a MAS 11 X 6 two bladed prop. You will get much more thrust than with your 10 inch prop. Try it--you'll be amazed. Also, you don't have to purchase the prop driver. The weighted flywheel is just pressed on--you can easily remove it. Open the jaws of a vice wide enough that the weighted ring sets on the jaws, but the prop driver itself doesn't. Then, using a large socket (about the diameter of the prop driver), knock the driver out of the weighted ring. Bingo, you have the same thing that you just paid 10 bucks for....
