Back at it.

Assembled the gear diffs.  They're functional, but I fully intend to look into a substantially thicker grease (or the optional ball diffs) to keep both wheels moving.



This would be a good time to point out that the kit comes with a bag full of bushings.  They're all over the place.  Anything that spins spins on bushings.  Ugly, crunchy, power-robbing bushings...  The first mod for this truck has to be a set of bearings.  Before you upgrade anything else, get bearings.  Seriously.

I bought a full set of bearings before I even opened the box.  $8 on eBay.



Next up is the top shaft.  On the stock [black] shaft has the belt-spinny things are held in place by hingepins.  These shear off under load.  You'll be having fun and the next thing you know, the truck is FWD.  Theoretically, loosening the slipper would alleviate the problem.  But if you're running on-road and not running a slipper...   Or you hate the truck and want to destroy the drivetrain and you're running off-road without a slipper...

I had a RRP topshaft in my parts boxes.  Good thing, too; they're nearly impossible to find now.



After bolting everything together per the instructions, it was time to attach the rear bulkhead assembly to the chassis.





It's best to unscrew the shaft that connects the two halves a bit as the holes are difficult to line up with the chassis with that shaft fully tightened.  It took me a while to figure that out...  Once attached, it finally begins to look like an RC car.





At this stage of the build, the RS4 family resemblance really shows.  At the top of the pic is an original RS4 Pro.  In the middle is an Pro2   And at the bottom is the RS4 MT.
