Reflex Racing 1/28 Scale Rotor Gauss Checker for Mini-Z Motors [Reflex Racing] RRE036

This Rotor Tester allows you to check the magnetic strength and balance of the rotor of your 1/28 scale motor.

By checking the strength, you can find which rotor will give more or less magnetic field to help you optimize the set up of your motor.  The tester checks 3 points on the rotor (Left, Right, Center) and gives you a read out of the positive and negative side of the magnet.  The closer matched the numbers of your rotor Positive to Negative, the smoother your motor will run.  

To operate, please provide 7-12V DC supply with 4mm female output.  Once powered on first re-set the machine and then position rotor with pinion side to the left as pictured in the images above.  Rotate the rotor with your finger until you find the high point of each side of the magnet. 

This set comes with neoprene case for safe storage.
