I went to amainhobbies racetrack this morning to run some laps on mine, running a MMM 1410 combo, truck feels VERY nice. It's fast but also smooth and quite predictable, it drives like a fast stadium truck IMO.
One issue though, after driving an hour and a half to get to the track, in the middle of the first pack a shock piston screw broke off, flush with the end of the shaft and I couldn't get it out so my day was done quite early
