Slipperential for other vehicles that can't use the current model?

[RC-Monster Mike]

The Hyper 9 and MP9 are the only 2 1/8 vehicles that the Slipperential won't drop into right now - probably easier to make a mount that allows it to fit rather than re-invent the Slipperential - it took a lot of work to get the Sliperential into the small size it is currently. :)
