WMH Racing V2 540 and 550 Rotor Masters

New from WMH Racing is its V2 540 and 550 rotor masters which are designed to measure the strength (gauss) of your rotor.  Measuring the strength of your rotor is important for a number of reasons as the rotor strength changes, so does the performance of the motor. By being able to measure the strength of the rotor you can measure the change and determine when it’s time for a new rotor. New rotors often bring back better performance into used motors.  Testing different rotor combinations in your motor by measuring the rotor strength you can determine the difference between 2 otherwise identical rotors.  Have a weaker or stronger rotor plays a huge role in the timing and gearing used for that motor.  Gearing/timing/rotor strength can be optimised for your track, giving you the performance advantage.  You can also compare your power package to your friend-enemies. If you know your friend has the same motor and is much slower/faster with the same gearing/timing, there is likely a difference in rotor strength. By measuring the rotor strength you can determine the reasons why you are slower/faster.
