RE: XTM vs HPI
I do love some roto-start....
The Xcell comes with a different radio now though, a hi-tec, but I don't know the model. I do know it is better than whatever it used to come with.
On the local shop-thing... our local hobby shops rob people blind, I buy 95% or more of what I have from the web. The parts are available here w/no problems.
On the other hand the RUSH does alot MORE available hopups, and like you said, it's HPI...
