Cyclone S Tips: Speed. When you don't need it.

A stock motor which has high revs/rpms on a machine like the much-more motor master will most likely be useless on the track. The Motor will be likely to have very low torque, which means even though you are revving at 25,000 rpm, you will actually only getting 15,000 rpm when it is in your car because it has to push this heavy car around the track.

To race competitively in stock you need a motor with an in between of torque and rpm.
And motors which are supposed to be competitive on a motor machine when under no load are likely crap on the track.

Also, when a motor is geared in the 4.1-3.9 range, you tend to get it a little bit to hot. So be conservative with your gearing and if its a new motor, gear it below your normal ratio to see whether it needs that higher ratio.
