Metal Rotor Head Cap Upgrade Set for RC ERA C189 MD500

The Ultimate Aesthetic and Durability Upgrade

Plastic rotor caps can become stripped or cracked over time, leading to a loose rotor assembly and a "cheap" look. This machined aluminum rotor cap solves durability issues while providing a high-end, professional finish to your scale MD500, ensuring your main rotor assembly remains securely fastened and visually stunning. Ships worldwide.

Product Highlights

• Impact Protection: Unlike plastic, this metal cap protects the central rotor head screw from dirt and impact damage during rough landings.

• Premium Scale Finish: Features a polished metallic look that perfectly complements the high-detail scale fuselage of the RC ERA C189.

• Vibration Reduction: The increased rigidity and precision weight of the metal cap help stabilize the rotor head spin at high RPMs.

Compatibility

For the RC ERA C189 Brushless RC Helicopter only.

What’s in the Box

• 1 x Metal Rotor Head Cap Set（As shown in the figure.）

Install Tips

• Thread Locker Required: Since this is a metal-on-metal connection, apply a tiny drop of blue thread locker to the mounting screw to prevent it from vibrating loose.

• Manual Tightening: Hand-tighten the cap until snug; do not use power tools, as you want to avoid over-compressing the feathering shaft assembly underneath.

• Centering: Ensure the cap is perfectly centered on the rotor hub before final tightening to prevent high-speed centrifugal imbalance.
