Yes, I remember this discussion.
I believe what the picture fails to illustrate is:
The back of the can is attached only to the diff housing. The can is attached to the shaft running through it by a bearing only. No longer a press fit with a set screw.
It would effectively spin the diff housing just like a spur gear spins a center diff.
I believe this design WILL work, but............there's always a but.
Current diff designs do not support this setup. Both in available gear ratios and toughness.
The lowest toughest gear ratio on the market currently is the 13/43 diff setup. I do know MT tires in the 5.75" size won't work with this without cogging. Perhaps a smaller tire size will.
Granted, the diff unloading to the front will cut down on some of the abuse. This then switches the game into trying to not make the diff unload.
This center diff will need the thickest grease you can find, and then some.
One other thing this setup needs, is a good HV ESC with the Mamba Car Software. Come on Castle. LOL
Some thoughts need to be spent on Motor Cooling also. A fan made into the endbell along with an Aluminum motor mount/chassis will help things greatly.
A Really Low KV Motor on 8S to 12S would be hard to beat.
