The truck has each axle (of which, neither have differentials) driven directly through a 1.35 to 1 gear ratio. The truck uses an M-motor in the front section to drive a small linear actuator through a 1 to 1.35 bevel gearbox. The actuator rotates the front half (with the battery box, front motor, and cabin) around the pivot by pulling on the back half (with the bed, rear motor, and IR receiver). It even has a small enclosed compartment in front of the battery box.
Because all wheels are driven on this vehicle, it has superior off-road capability compared to the six-wheeler. It can handle dirt and bark chips much better, and the articulated steering is as effective as ever. The only problem is that it can't handle driving through grass, and I think this is a common feature to wheeled vehicles I've made. The RC front loader had a much shorter wheelbase and was capable of limited cross-grass operations, but the best vehicle I've made concerning cross-grass capabilities is my tank series, but the treads occasionally got stuck in tall grass, which was always irritating.
