HobbyStar 540 4-Pole Brushless Sensored Crawler Motor
$49.99
Unit price perThe HobbyStar 540 4-pole brushless, sensored crawler motor is an ultra-smooth powerplant for upgrading your crawler to brushless power. A beautifully machined T6 billet-aluminum housing contains a 4-pole, 12-slot high-torque rotor spinning on High-RPM ABEC5 oversized bearings for a powerful, reliable motor choice for your 1/10 scale vehicle.
NOTE: Max LiPo cells listed are a guideline for what voltage can be safely run on this motor, but it is still critical to monitor temps and adjust gearing accordingly to keep motor temps under 170F. Any motor can overheat to the point of failure even when running less than the maximum rated voltage if it is over-geared. Must adhere to ESC voltage/KV limits as well.
