Hi Matt, I used my brand new 17.5 murfdog motor last night in my short course truck. All I can say is WOW! I am very impressed with this motor! I ran against a mix of modd motor'd short courses.. I was able to keep up and beat most of them with my motor, well chassis set up was perfect too. I absolutely love how smooth the power delivery is and how cool the motor ran, never got over 125 degrees in a 7 minute heat. My hats off to you Matt! thanks!
