i have the rs4 mt, i got it a few years back when it came out. it was fun for a bit, but i moved on to 1/8th scale gas offroad. i dont really use it anymore. now, the nitro rs4 mt is a different story. i saw 2 of those run at the local offroad track yesterday. a stock one and a modded one. both were very impressive, especially the modded one. i am very impressed with its speed, jumping capability, and handling on the track.
