WLtoys K170 Linkage Set 02 - Upper Rotor Head Links for UH-60L

Correct Blade Tracking and Flight Instability

If your helicopter vibrates excessively or the two main blades appear to be spinning at different heights (poor tracking), your upper linkages are likely bent or stretched. This WLtoys K170 Linkage Set (02) solves the problem of mechanical play between the swashplate and the blade grips. By restoring perfect geometric alignment, it ensures smooth lift and eliminates the wobbling that can lead to gyro failure. Ships worldwide.

Product Highlights

• High-Precision Molding: Factory-spec ball ends provide a tight, "zero-slop" fit onto the swashplate and blade grip balls.

• Balanced Lift Profile: Designed to maintain the exact distance required for symmetrical blade pitch, ensuring stable hovering.

• Durable Steel & Composite: The metal rods resist bending under high-G maneuvers while the plastic ends absorb minor impact energy.

Compatibility

Install Tips

• Snap Direction: Note that the ball links have a specific orientation; the side with the larger opening should be snapped onto the ball first to avoid cracking the plastic.

• Length Matching: Use a digital caliper to match the length of the new rods to your original ones to minimize the need for electronic trimming.

• Smooth Movement Check: After snapping them on, ensure the links move freely on the ball without binding, which could cause servo strain.
