Re: Last Year's Gear Ratio

Also for this to be meaningful, you may want to consider which motors are being used for driving. While many use CIM's, some also use FP's and/or the mini-bike CIM (fat chip). Therefore the gear ratios used for those motors should not be compared with other motors.

We used 12:1 Banebots with the DUAL CIM configuration and additional 1.3:1 geardown to the 6" wheels for a total of about 16:1. The results end up with 6.25 ft/s at 40 Amp draw and 9 ft/s at free speed. No shifters last year.
