Compact 3CIM Single Speed Gearbox Review

[Cash4587]

Gearing our 4cim 2 mini cim drive at 10.04:1 this year with 8" wheels made us suffer bad brownout problems. Our batteries would barely get us through a match. We bumped our gear ratio up to about 12:1 or something, this off season and have had much better results. I really suggest you test your gearing with 6cims before building this during a season, you might not move at all due to browning out. Wheel diameter will be a big factor too, so smaller wheels could help with this.
