Main Rotor Head Assembly Set for Kootai F05 Black Hawk (Hub + 4 Shafts + 4 Screws)

Total Rotor Head Refresh Kit

A major crash often damages more than just the rotor hub—it bends the feathering shafts and shears the screws. This comprehensive assembly set solves the headache of sourcing individual parts, providing a complete structural refresh for your Kootai F05's rotor system to get you back in the air with factory-standard precision. Ships worldwide.

Product Highlights

• Comprehensive Upgrade Pack: Includes 1x 6061 Aluminum Rotor Head, 4x Hardened 420 Steel Feathering Shafts, and 4x Nickel-Plated Screws (1.2*3PM).

• Hardened 50HRC Steel Shafts: The four included feathering shafts are quenched for maximum hardness, resisting bending during hard landings or high-stress maneuvers.

• Premium Finishing: Components are either anodized or nickel-plated for an eco-friendly, rust-resistant finish that ensures longevity and low-friction movement.

• Direct OEM Replacement: Every part in this set is matched to original F05 specifications for a perfect "drop-in" installation.

What’s in the Box

• Main Rotor Head Assembly Set (Hub + 4 Shafts + 4 Screws)

Install Tips

• Thread Lock Required: Use a small amount of medium-strength (blue) thread locker on the 1.2*3PM screws to prevent them from backing out due to high-speed rotation.

• Shaft Replacement: We recommend replacing all shafts simultaneously to ensure consistent hardness and balance across the entire rotor assembly.

• Bearing Inspection: When assembling the feathering shafts into the hub, ensure the thrust bearings inside the blade grips are cleaned and greased for the smoothest operation.
