Now for the down side. You are still using a brushed motor that will have marginally better life that the stock motor, if any. This is why others are working on perfecting the brushless tail mod. I was doing the same thing, opting to use a 12mm inrunner that bolts in the place of the stock motor, but went the F45/450 route instead because the electronics difficulties of the brushless mod are beyond me.
Actually, several tried the direct drive extreme and eflight brushed motors and reported they did not work as good as the stock motor. They where both designed to run on 11 volts and it appears on 7.4, they are not fast enough.
