How much does the inter axles drive shaft move in and out? I always have trouble with this shaft popping out because of how short it is and how much articulation I try to get out of the stock Tamiya suspension?

I was thinking about making a walking beam that rubber mounts the axles to the beams and thus keeps the inter axel drive-shaft angle straight at all times. only the front shaft would move in and out of the tube to take up the length difference when traveling over bumps. I know your example is more 1:1 but I always have issues with lots of articulation and the little driveshaft. I went back to the tamiya cups and dog bones between both drive axels because they were performing better than the scale driveshafts did.
