In addition to Dr. J's comments, the speed will also be affected greatly by the battery supply voltage. If using a fresh, fully charged battery, a voltage of over 13 VDC would not be uncommon. Likewise, after a match or two and under 'competition' loading, the battery voltage can easily dip to under 11 VDC. This variation in supply voltage will definately affect motor performance.

'... your RPM may vary.'
