Drivetrains in Ultimate Ascent

[JesseK]

We're running 4WD WCD, direct-driven via VexPro single speed gearboxes and a 2nd VexPro gear stage to 4" AM Performance wheels. Can't remember what the final ratio is, but the speed is roughly 11.6ft/s before losses. The wheelbase is 30" wide x 18.5" long. Center of Gravity is biased 4" forward of front/rear center, and is nearly perfectly balanced left/right. It took us 1.5 weeks to fab it, and most of that was waiting to figure out what the frame would look like due to climbing and/or floor pickup. It weighs only 24.5 lbs and cost less than the kitbot because we made everything in-house.

Man does it fly too.
