If you had an original diff from an early car then you could probably get away with a very mild motor but it wouldn't last long. I think the best combo is rc10 b4 diff halves, diff plates and thrust bearing with a mardave cobra diff gear and schumacher balls. Bearings will need a slight modification. It's not hard to do and is reliable.

Fully agree with what Adey says or do what I did with mine and graft a Mad Rat gearbox onto the Cobra's chassis.
The Mardave diff in mine's original box wouldn't stay set for more than a couple of minutes with a
27t Parma Cyclone brushed superstock before slipping its boollox off.
I've run a 19x1t Comodo Dragon,a 17x2 TMS Challenger and a 15x3 Reedy
on the 'Rat box,trust me,it goes well on a Ni-Cad with the Dragon and flies with either the Challenger or the Reedy,never tried it with a Li-Po(too much dinero for Mrs Miggers to sanction the purchase of
).
Mine is also permanently set up for dirt/dusty clay too.
What're you running yours on Blue? astro judging from the cut-staggers up front and the shock angles.
Try JC Racing for five spokes:
