The feathering shaft (spindle shaft) is a critical component that bears the immense centrifugal force of the main blades. Stock shafts can bend during crashes, leading to severe vibrations and "toilet bowl effect" (TBE). This hardened 420 steel set provides the rigidity needed for precision 3D maneuvers and long-term durability. Ships worldwide.
Product Highlights
Industrial Grade 420 Steel: Quenched to a hardness of 50HRC, these shafts are significantly more resistant to bending than standard replacements.
Eco-Friendly Nickel Plating: The smooth nickel finish reduces friction against dampers and bearings while providing superior corrosion resistance.
Precision Machining: Guaranteed concentricity ensures the rotor head remains perfectly balanced, eliminating unwanted flight vibrations.
Bulk 4-Piece Pack: Provides excellent value and ensures you have spares ready in your field kit for quick repairs.
Bearing Inspection: When replacing a bent shaft, always check your main blade grip bearings for damage, as a crash often impacts both.
Thread Lock Application: Use a tiny amount of medium-strength (blue) thread locker on the screws to prevent them from backing out due to high-speed rotation.
Smoothness Test: After tightening, ensure the blade grips rotate smoothly. If they feel "notchy," check if the dampers are properly seated or if the screws are over-tightened.
