HobbyStar 3660 4-Pole Waterproof Brushless Sensorless Motor

HobbyStar 3660 4-pole brushless motor provides increased torque when compared to a standard 3650 while still providing top-end power. Versatile waterproof design allows you to drive in extreme conditions and motor leads come with pre-installed 4.0mm gold-plated bullet plugs for easy, no-soldering connection. Features: 4-pole motor with 12-slot high-torque design High-purity copper windings maximize efficiency High-RPM ABEC5 oversized bearings Precision balanced rotor for smooth operation and maximum RPM Super-thin (0.2mm) stator laminations  Voltage recommendations in the table below are guidelines for the voltage you can safely run.  It is still critical that the user monitor motor temps and adjust gearing if necessary, any motor can overheat to the point of destruction if over-geared even when running at or below the rated voltage.
