Main Brushless Motor for RC ERA C189 MD500 Helicopter
Restore Factory Power and Efficiency
A worn or damaged motor can cause power loss, overheating, or erratic RPM, leading to poor altitude hold and reduced flight times. This official high-torque brushless motor solves power delivery failures, restoring the smooth, quiet, and powerful flight characteristics that the RC ERA C189 is famous for. Ships worldwide.
Product Highlights
High-RPM Brushless Efficiency: Specifically wound to provide the optimal power-to-weight ratio for the 1:28 scale C189 airframe.
Internal Cooling Design: Features an open-bell or vented design that facilitates airflow, preventing thermal shutdown during aggressive flight maneuvers.
Pre-Installed Pinion Gear: Comes with the factory-matched metal pinion gear already pressed onto the shaft, ensuring perfect mesh with the main gear.
Maintenance-Free Longevity: High-quality ball bearings and a brushless design mean no brushes to wear out, providing hundreds of flight hours of reliability.
Gear Mesh: When mounting the motor, ensure there is a tiny amount of "play" (backlash) between the motor pinion and the main gear; a tight mesh will cause overheating.
Screw Security: Use blue thread locker on the motor mounting screws to prevent them from vibrating loose due to the high-speed rotation.
Connector Check: Ensure the three-wire brushless connector is fully seated into the ESC/Mainboard; loose connections can cause motor "stuttering" or failure.
