The weight of a tank will not tolerate common differentials, assuming it is powered by 2 or more XL motors. I can see only reinforced custom diffs as posted above viable for such tracked vehicles. To add to the same question: are there any options to replace usual technic axles to more reinforced variant? Because of all the torque directed to the sprocket, axles bend too easily and I found dust from grinding axles even when vehicle runs idle lifted above ground.
