Actually the motor doesn't have to be a 10mil. I just want the motor I can get the most power out of. And I'm wanting the motor to not have to stick out of the fame to much. A little is fine. I just didn't know what motor and size would be the best for most absolute power because they are so many now, cubs, super cubs, cheetahs, serval's, dm's, and the list goes on. Hope this thread is right up domes alley. Thanks fellas
