I had the 4 pole geared with 16/62 and was temping at 150ish at the track. Hopefully it doesnt rain tomorrow and I can try out the 2650. The 2650 gets up to speed quick and so far the truck likes the extra weight. Well see what the track thinks... The current setup on the 2650 got to a wopping 79 degrees, with any luck I can get the smaller spur and run a 20 tooth pinon. I had the 2650 laying around and figured I couldnt let all the losi guys have all the fun without at least trying.
