Re: pic: Gear Drive Concept

Another iteration:

60t gears running down the whole length. A stock vexpro 2-stage 2 cim ball shifter can be face mounted to any of the hex bearings depending on space and or orientation needs. 10wd/6wd 1/8in drop center - flip the chassis upside down for 8wd 1/8in drop center. All of the gears are installed via reciprocal slots in the tube.

Stock ratios: 3.61:1 High, 8.33:1 Low. JVN Calc says that on 3.25 wheels, its a 16.6fps / 7.3fps split.
