This project is still on, just been waiting for the time. Truckbasher's E-Revo outrunner project comes first, although I have put a lot of thought into the Corr truck while at work. For example, last Saturday while I was at work (the LHS) a customer came in, got some parts, pointed at one of the images of a CORR truck on a Slayer box, and said he had that truck outside.

It was Scott Douglas's truck, straight from being repaired after his recent bad crash.
The guy gave us a nice tour of it, so I got some pictures

Front suspension/driveshaft:

Rear suspension:
The rear suspension was definitely the most interesting part of this truck to me

. They designed it unlike other suspension setups out there, with parallel upper links mounted next to the shocks on the axle housing, and chassis-triangulated lower links. From what the technician guy said this suspension setup drastically reduces or eliminates the axle steer typical 4-link setups have when the axle articulates. And it's just as effective as a normal 4-link.
That does mean I will be trying to imitate this suspension design on my CORR truck project

. Before I build it though, I will have to play around with the geometry.
