And if you think speed is a problem.
Bullfrog uses a 20-1 gearratio and 250mm Full foam wheels, with 170 KV 120mm diameter motors on 10S.
We can put a 15:1 ratio in without much bother, but even with higher KV motors (250, 80mm) I'd be worried about how slow we'd go - with luck, that might maybe touch 10mph. With using higher ratios, I'd also be a bit worried about trashing the gears at a higher ratio.

What sorts of speeds should I be looking to realistically achieve?
