After more research ill be going with a new differential design to be more accurate to the real sdkfz 250. heres a webpage that explains it better then I can. the page is about the Kettenkrad but the sdkfz 250 used a very similar diff just more with more gears. http://www.livesteammodels.co.uk/dhmg/kettenkrad15.html
Heres a vid of the diff from a sdkfz 251. http://www.youtube.com/watch?v=GjtNy05EOB4 Heres a vid of the studebaker weasels diff witch is also the same type. http://www.youtube.com/watch?v=-uRdVOYCb_M I just received the 250 watt motor, its bigger then I was thinking but should still fit nicely in the engine compartment. I plan on mounting a 24v fan where the radiator would be to keep that big motor cool.
