This is a single axle with a hub that mounts to our 10 inch tires. The end opposite the hub is bored to fit a 12mm shaft. It is intended to be direct driven by our IG52 motors. The hub is welded to a steel 5/8" diameter shaft.
This prebuilt RTR robot uses our standard ATR chassis and 10 inch tires. We have included everything to make it ready to run including batteries, controllers, chargers, etc. Upgraded drive train with encoders on each motor set to speed control.
