I wanted to try a 3x3 concept, which would allow me to ditch suspension and make the model less complex. I used an XL motor for each side drive, and a differential to power the rear wheel. When you go forward all 3 wheels are powered. When one side wheel stops, the rear wheel spins at half a speed. Weight was mostly at the front axle, which helped model cimb up stairs very good, but made it flip going downhill. Also it tends to break 12 tooth gears when you stall it manually, but otherwise works normally when driving uphill or over obstacles.

It was a good experiment, but I am not gonna develop it any forward, because of lack of stability.
