What's wrong with a 2-speed E-Revo?

I think you're better off with the stock emaxx transmission. get the half tranny conversion and, if you have an adjustable power supply, run the motors for about 30 minutes at 6 volts, Blow all the grease out of the bearings (all of them) and use a light oil, you have to maintain them more often but cuts the friction loss nearly in half. If the track is mid to long, get a 64 tooth spur gear to get a few more MPH
