I received the the 950R back a few months ago, and ran it at our regionals. Worked very, very well. It is much easier to work on that the 950. The new suspension works great. The parts quality is much better than any of the older cars. First race out and it was running with all of the top mugens. I was on a new TQ pace every run, but we had rediculous problems, like the battery dumping, but none of the problems were due to the car's quality.
