I just ordered the matching male bullets for the motor that work with the female on the ESC. I like to leave the ESC wires alone if possible.

The ESC has 3.5mm female. And according to towerhobbies listing, the motor comes with 2mm female, w/ the male inside them, but I actually think that is wrong. The Great Planes web site says they come with the correct 3.5mm female w/ male inside. You might just have to take the male connectors out of the female on the motor wires, cut the female off and solder on the male ones. That should do it.
