I've moved on again, although the labor to get to this point has been quite a bit.

Anyway, I have to say that after the first drive test I had to re-evaluate the parameters and replace the motors with stronger ones and the gearboxes with even slower ones.
Although the MFA motors, which I also have in my T-34, improved the drivability quite a bit, I still preferred to play it safe and replace the 1:100 planetary gears with 1:200.
Otherwise, sounds and other details are still to be solved, it was not the subject of testing...

...judge the result yourself...
