WLtoys XK K270 Blade Grips Rotor Blade Holders for UH-60L Black Hawk

Restore Rotor Head Alignment, Eliminate Blade Slop, and Stop Severe Rotor Vibration

A cracked, warped, or fractured main blade grip set on your WLtoys XK K270 UH-60L Black Hawk RC Helicopter severely degrades flight stability, causing intense rotor head tracking vibration, pitch imbalance, and altitude hold instability. Hard main rotor strikes, ground tip-overs, or high aerodynamic stress during aggressive maneuvers can fracture micro blade holders or loosen feathering shaft mounting threads. Flying with damaged blade grips introduces severe slop at the blade pivot points, causing premature wear on linkages and risking a catastrophic mid-air blade throw. This official WLtoys XK K270 Main Blade Grips set delivers an exact factory replacement. Precision-molded from high-impact composite material, it securely locks main blades in alignment while ensuring butter-smooth pitch rotation around the rotor hub. Ships worldwide.

Product Highlights

• Reinforced High-Impact Composite Material: Engineered to absorb flight vibrations and landing impacts without flexing, cracking, or distorting blade alignment.

• Factory Precision Feathering Shaft Bore: Fits seamlessly over the rotor feathering spindle shaft with zero play, ensuring smooth cyclic and pitch movement.

• Integrated Linkage Ball Stud Mounts: Includes molded mounting points to connect pitch linkage pushrods directly for slop-free 1:1 swashplate input transfer.

• Balanced Factory Geometry: Built to exact scale specifications to preserve optimal rotor head center of gravity and aerodynamic tracking out of the box.

Install Tips

• Disassembling Damaged Blade Grips: Remove the main rotor blade retaining bolts, slide off the damaged blade grips, and inspect the central feathering shaft for bends.

• Mounting Replacement Blade Grips: Slide the WLtoys XK K270 Main Blade Grips onto the feathering shaft ends, ensuring internal dampening washers and bearings are properly seated.

• Securing Main Rotor Blades: Insert the main blades into the grip slots and tighten the retaining screws until the blades hold firm horizontally but pivot smoothly under firm finger force.

• Pre-Flight Movement & Tracking Test: Rotate the rotor head manually to verify smooth pitch pivoting without binding, then check blade tracking alignment at low RPM before full takeoff.
