Dual Revo 3.3 BL conversion build-up

Well...

You could give it a try on 11.1v (3s lipo), 14.8 (4s) will spin the motor too fast and cause alot of heat. You can get a 9t pinion from century and use one of mike's bore reducers so that it will fit on the 1/8 shaft of the 4600. With 40/9 gearing it would top out at 30mph in 2nd gear, so it may be ok. Here is the copy of briang's speed calc so that you can see what I used to get the numbers:
