This Saturday my UNIMOG had an accident, where it tipped over and the rear wheel set became blocked. The result was that the rear propeller shaft broke. See the pictures below. I must say that I am quite impressed with the force that the motor and gear box delivers. Deforming this axle like that is not something you do with your hands. Now I ordered the TAMIYA carbon steel propeller shafts for the CR-01 chassis. These will most likely last. The bad thing is that my UNIMOG is broken until I get the spare parts.
