I'm pretty sure that the Graupner 300 based motors are faster then the stock rc18t motors and I have heard that the Fireball is faster then the 300. I need power to run on a 1/10 track.
i dont race my mrs4, i drift with it. i have run the above motors in my mini-t and the graupner speed 300 v6 is faster than both the 18t and the fireball motor! what size is the track you will be running on and how technical? with the fireball id start low pinion wise. i was runnin a 10 on mine for drifting and it still got pretty darn hot! theres alot of low end throttle while drifting so it may stay a tad cooler under more open racing conditions. mine didnt bolt right up to the motor plate on my mrs4 either. had to dremmel a little out of the plate for the venom! hope this all helps!
