This is a refresh from Multicopter Builders of their 2207 motors.
The internal changes to the motor here are interesting. The tested kV comes in almost identical to the orginal MB2207 2400kv, and the results show some interesting factors. The results on the lighter props are almost identical to the old motor, but as the torque loading increases there is increased seperation in favor of the new design. On 6" props the difference is fairly dramatic. This really demonstrates the effect of varying torque production with two motors of otherwise very similar design parameters. This motor is a strong contender for the freestyle market where the mid weight, high torque and large range of prop selection is ideal. The mid-range kV also makes this motor ideal for stepping up to 5S, where the taller stator size will really put the voltage to work.
