We built a 6-wheel drive VEXpro chassis
shown in our mid-season video (
non-youtube version )
6:1 single speed vex gearbox , 24:12 sprockets , 4" versa wheels, 6 motors.
We were impressed with the acceleration but also a bit worried about the sensitivity (driving straight takes some practice). We are thinking about adding exponential control to make small joystick changes less noticeable and low speeds .
I'm curious to know what ratios other teams are using ?
