Ok normally by installing a lower tooth count pinion gear the speeds go down/torque goes up but with this setup you go from a 28t count and single battery (or dual in parallel) for 30mph to a 23t count and dual batteries in series for 50 mph. So what kinds of speeds could this E-Revo get up to running the 28t with dual batteries in series? Anyone know or that have theirs already tried this? And if there is anything that can go wrong such as overheating issues or something like that. Thanks Guys
