i want traction roll too!
how to soften the rear end with the graphite chassis? 
too stiff now!
Chop up the back end with a dremel cutter. If you look in the HPI site in their Micro furom, one of the HPI staff did this. However, I would be more tempted to do some "serious" slicing and dicing on the graphite chassis.... chop it right up to the servo position!
