hey funflyerf4, I suppose I really shouldn't bud in here, to many of the guys above know there stuff well, but I'd look at it like this, first whats does your patriot weigh?, secondly with the prop you have , does it unload much in the air?, I know most have advised you to stay with a 9 inch diameter, but playing with the numbers in hp, and IF you get a resonable take off with the current prop...I would really be tempted to try a a 9 x 10 cut down to 8 1/2 x 10, the 60lx should have enough torque in it to handle this..but I'd look at the above questions first

either way hope you get it sorted out
