Main Rotor Feathering Spindle Screws Set for RC ERA C189 MD500

Maximum Safety for High-RPM Rotors

The feathering spindle screws are the only hardware holding your main rotor blades to the hub while spinning at high speeds. These screws are subject to extreme centripetal force; a loose or stripped screw can lead to catastrophic blade ejection. This official screw set solves the safety risks associated with worn hardware, ensuring your rotor assembly remains rock-solid during high-G maneuvers. Ships worldwide.

Product Highlights

• High-Tensile Steel: Manufactured to withstand the constant tension and vibration of the C189's main rotor system.

• Precision Thread Pitch: Factory-spec threading ensures a perfect, no-slop fit into the feathering shaft (cross-shaft).

• Low-Profile Head: Designed to sit flush within the blade grips to maintain aerodynamic balance and prevent contact with the swashplate linkages.

• Anti-Corrosive Coating: Features a protective finish to prevent rust from humidity, ensuring the screws remain easy to remove for future maintenance.

Compatibility

What’s in the Box

• 1 x Set of Feathering Spindle Screws 

Install Tips

• Thread Locker: Critical Step: Always apply a small drop of blue (medium strength) thread locker to the threads before installation to prevent vibration from loosening the screws mid-flight.

• Dual-Tool Method: Use two screwdrivers—one on each side of the spindle—to tighten the screws against each other for a secure lock.

• Tension Check: Tighten until there is no lateral "play" in the blade grips, but ensure the grips can still rotate smoothly without binding.
