This seems like a good thread for me too! I just bought an Associated 18R (1/18 scale), it's a lil' drifter. I put a Mamba 8000 Brushless system in it with a two cell lipo, and put PVC on the rims. The large brushless/lipo set up is way overkill on the power, but I'll probably go back and forth between grip racing and drifting. I wish I could find something with just a little more traction. It drifts WAY good on carpet and pretty good on cement, but asphalt drives like ice. The tires it came with are very "grippy", so they're good for speed runs or driving on a track, but the PVC seems a little too slick. I noticed people talk about abs and hdpe; are either of these a softer compound that might grab just a little more than PVC? Thanks for your help.
