Motor Tuning: High RPM vs High Torque rotors explained

In this video I compare the KV and Amp results from a fixed timing 17.5T brushless electric motor that had a high rpm rotor in it and change it to a high torque rotor and show the difference it makes in rpm and amp draw.
In general, in a brushless motor a high strength rotor(1600+ milligauss) will draw more amps but show less rpm, where a low strength rotor(1500 milligauss) will draw less amps but have a higher rpm. You can use this knowledge to tune your motor for your track conditions.
