theres a sweat spot where the motor is fastest then when you make it smaller the performance go's down.
depending on how you cut you brush too.
but its still easier than a damm nitro motor.
I found that as long as you geared properly the Epic based motors get faster as the com decreases to about 7.2 mm - then they just overheat and run strong for 2-3 min... after that, they die off quickly in a race.
