Update on the experimental dromida (big motor tiny car), its officially dead. I got a WLtoys a949 for christmas, which kinda satisfies the big motor tiny car dream I have. And I needed parts from the experiment for various other things.

Now I have to figure out what Im going to do with the kinda expensive duratraqx ball diffs. They do indeed fit in a dromida gear box (as mentioned in this thread), but the bearings on either side are too small, so, it kinda rattles around in there.
