Thanks for the help pompebled, I'll have to try that and see how it goes.

Since I'm on a very small budget right now I went and got a Traxxas 12t Titan motor today, I'm ordering a 1/8 to 4mm coupler from offshoreelectrics.com to couple it to the stock driveshaft. I'm going to cut the shaft and the stuffing tube down on the inside and fabricate my own mount for the motor. This will allow me to at least get the boat running, and then I can upgrade to a brushless setup when the time comes.
