Main Rotor Spindle Feathering Shaft Set for WLtoys K170 UH-60L

Eliminate Rotor Vibration and Mechanical Wobble

A bent spindle shaft is the most common cause of high-frequency vibration after a minor rotor strike. Even a microscopic deviation in the shaft prevents the blades from tracking on the same plane, leading to unstable flight and gyro interference. This WLtoys K170 Spindle Shaft set solves tracking issues, restoring the "butter-smooth" rotation required for precise 4CH scale maneuvers. Ships worldwide.

Product Highlights

• High-Tensile Steel Construction: Engineered to resist bending under the high centrifugal forces of the K170’s brushless power system.

• Precision Polished Finish: Reduces friction within the blade grip bearings, ensuring free movement and rapid pitch response.

• Perfect Factory Fit: Designed specifically for the K170 rotor head, featuring the exact length for a secure, slop-free assembly.

• Flight Safety Essential: Critical hardware that ensures your main blades remain safely attached to the rotor head during high-speed flight.
