Rear suspension help.

[moogie]

Could anyone direct me to a post i seen on here a while ago ?
It was for a truck with a cantilever type rear suspension setup which was made out of aluminum and gave much more articulation than the standard Tamiya twin drive setup. There was also a video posted on Youtube showing its operation.
Sorry this is a bit vague, but somebody else might have a better memory than i have.
Thanks, Noel.
