Metal Man, your thing looks well made. I, too, ran into the same calculations.

In my customized Revo I would have lots of space for a huge spur. I always think of a very big gear attached to a center diff (with or without slipper) right in the middle of the truck. I could make room for the big spur and reinforce the chassis next to it (if it's not strong enough anyway).

The real challenge would then be the diff brace, which should include a motor mount.
If only I would have access to some proper tools or have a contact to a cool machinist ....

I also have put the center diff project to a rest, the g-maxx tranny made me change my mind, but I will come back to this later on. Maybe I'll have the possibility to work together with someone, one fine day.
