Got my MRS4 on a track tonite for the first time and I gotta say I'm very pleasantly surprised. The track was perfectly suited to a car this size. I had to run in a mod class and there were only 2 other people in the class with me. Apparently the big class is the RC18r and all of the rest go into a mod class which is basically a few MRS4's and a bunch of M18's. Once I got the dust from my garage floor off of my foams the car stuck to the carpet like glue. I think with a better motor I'll be able to give those M18's a run. The one I went up against tonite was fast with his mamba 8000 but it looked like it was too much for this place. I'm thinking a Team Orion Elite Mod would do the trick nicely. Add a new rear shock and I'm golden. To think of all the trouble I had with this thing and now how much I love it is ridiculous.
