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

Eliminate Rotor Wobble and Improve Tracking

A bent horizontal spindle shaft is the most frequent cause of "blade tracking" issues, where one blade spins higher than the other. This WLtoys K170 Spindle Shaft set solves the problem of high-frequency vibrations that occur after a blade strike. By providing a perfectly straight axis for the blade grips, it ensures your Black Hawk maintains a smooth, level rotor disc for stable 4CH flight.. Ships worldwide.

Product Highlights

• Hardened Steel Construction: Built to resist bending under the high centrifugal forces of the K170's brushless motor system.

• Precision Machined Ends: Features factory-spec threading for a secure lock between the blade grips and the main rotor head.

• Vibration Reduction: Perfectly balanced to eliminate mechanical noise and gyro interference caused by shaft eccentricity.

Compatibility

What’s in the Box

• 1 x Main Rotor Spindle Shaft Set

Install Tips

• Thread Locker: Always apply a tiny drop of blue (medium) thread locker to the spindle screws to prevent them from backing out during high-speed rotation.

• Dual-Tool Tightening: Use two hex drivers at the same time—one on each end—to tighten the assembly securely without the shaft spinning freely.

• Check Dampers: While the spindle is removed, inspect the rubber O-ring dampers inside the rotor head; if they are torn, replace them to ensure maximum stability.
