WMH Racing V2 540 & 550 Rotor Masters

From DRC:
The 540 and 550 rotor masters are designed to measure the strength (gauss) of your rotor. Measuring the strength of your rotor is important for a number of reasons:

1. 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.
2. Testing different rotor combinations in your motors. 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 optimized for your track, giving you the performance advantage.
3. Comparing 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.

Key features and specifications:

• Power range 7-12v (2s or 3s battery, or power supply)
• Measures 3 area of your rotor strength (left, right and middle)
• Measures current and max value of rotor in 3 areas
• Reverse Polarity Protection
• Optimized calibration, for more accurate readings
• Instant data reset button
• Revised rotor cradle for more consistent rotor readings
• Measures up to 4000 Gauss
• LCD Screen
• Handcrafted in the USA!
• Comes with protective EVA zipper Case

These are available at drcproshop.com under the motor tools category.
