I think it's hit or miss with traxxas motors. My first 2.5 (that came with the truck) was a tuning nightmare from the beginning till the end. The one I have now has been rock solid since tank 1. Great temps, good power, no flameouts except when I leave it idle too long (I have the low end a tad rich to have above average lube since the motor is still pretty new).
