My Rc car's got 2 of these but way way tinier with carbide diff balls.....
associated rc18t (cute little guy) with a mamba 8000kv brushless setup and a 3 cell lipo.. the ball diff slips a bit sometimes lol.

These have largely been used in the RC car world because its alot easier to make them tiny as opposed to the bevel gear type, the larger cars and trucks do use gear differentials though.

i kinda wanna drive this base you got going...
