WLtoys K170 Main Motor Set - 4CH Brushless Power System for UH-60L

Restore Maximum Lift and Flight Efficiency

Over time, even brushless motors can lose efficiency due to bearing wear or magnet degradation from overheating. If your helicopter lacks the "punch" to climb or the motor sounds "gritty," this WLtoys K170 Main Motor set is the solution. It restores the high-torque performance needed to spin the 4-blade rotor head of the UH-60L, ensuring stable altitude hold and responsive throttle control. Ships worldwide.

Product Highlights

• Brushless Efficiency: Provides significantly more power and a much longer lifespan compared to traditional brushed motors, with lower maintenance requirements.

• Pre-Installed Pinion: Comes ready to install with the factory-matched gear pinion already secured to the motor shaft.

• High-Torque Outrunner Design: Specifically wound to provide the consistent RPM required for the heavy scale airframe of the Black Hawk.

• Plug-and-Play Connectors: Features high-quality bullet connectors that plug directly into the K170 ESC without soldering.

Install Tips

• Gear Mesh Adjustment: When mounting the motor to the frame, use a small strip of paper between the pinion and main gear to set the perfect gap before tightening the screws.

• Wire Routing: Ensure the three motor wires are routed away from the main gear and any moving linkages to prevent chafing during flight.

• Initialization: After connecting to the ESC, check the rotation direction. If it spins backward, simply swap any two of the three wire connections.
