I picked up the rtr (the one with the yellow body) version of the eight e 3.0 in November. I haven't been able to use it other than in my apartment. Has anybody been able to turn some laps in this car? I have been able to determine the servo sucks, but has anybody found any other weaknesses or strengths? I just wanted to get a bit of a leg up when our season opens. Any opinions or suggestions are welcome.
