Main Blade Propeller Set (4Pcs) for WLtoys XK K270 UH-60L Black Hawk

The Key to Smooth Lift and Scale Realism

Damaged main blades cause severe vibrations that can loosen screws and confuse the flight controller’s altitude hold sensor. This WLtoys K270 Main Blade Set solves the problem of lift-loss and wobbling. Designed as a complete 4-blade matched set, these propellers restore the smooth, quiet, and powerful lift profile that defines the UH-60L Black Hawk’s flight characteristics. Ships worldwide.

Product Highlights

• Matched 4-Blade Geometry: Specifically balanced as a set to ensure the 4-blade rotor head remains vibration-free during high-speed flight.

• Aerodynamic Efficiency: Features a high-lift profile that allows the brushless motor to operate at optimal RPMs, extending your flight time.

• Enhanced Durability: Made from a flexible yet rigid polymer that can survive minor grass strikes without snapping or permanent warping.

• Military Scale Design: Accurately replicates the look of the real Black Hawk rotors, complete with the characteristic blade tips for a professional finish.

Install Tips

• A/B Blade Tracking: Note the markings on the blades; ensure they are installed in the correct sequence around the rotor head to maintain mechanical timing.

• Screw Tension: The blade bolts should be tightened just enough so the blades don't flop when held sideways, but can still move if pushed firmly.

• Blade Alignment: After installation, pull all four blades out straight manually to ensure they are tracking on the same horizontal plane before your first spool-up.
