Well i recently fried two hacker 20 20l motors and hacker xpro 20 amp esc. It was on an aifoilz with the included 10x4.7 prop. Thanks to you guys and rcgroups i have concluded that i need a different prop. Some one recommended a 11x5 e fly. I will also borrow a watt meter to check the draw but i dont know what prop would theoretically be better in the first place. Also every time i put on the prop an expert helped me. How do i tighten the prop on the motor. An adjustable wrench and me trying to hold the motor doesnt seen to get it tight enough.

Thanks
Dan

I just picked up a mini edge 540 with the same motor and the phoenix 25 esc. It has the 10 x 4.7 prop on it. I plan on making a run to my hobby shop tomorrow to get a battery for it, I'll see what they say on the prop size too.

Thanks......
