Metal Rotor Head Assembly for RC ERA C189 MD500

The Ultimate Performance Upgrade

Plastic rotor heads can flex under the high torque of dual brushless motors, leading to vague control and tracking errors. This CNC-machined aluminum rotor head set solves airframe flex, providing a rigid and precise mounting platform for your main blades that dramatically improves the "locked-in" feel of your RC ERA C189. Ships worldwide.

Product Highlights

• Precision CNC Machining: Cut from high-grade aluminum for a perfect, zero-wobble fit on the main shaft.

• Increased Durability: Unlike plastic, this metal head won't crack or warp after minor strikes, keeping your flight geometry perfect over time.

• Enhanced Stability: The added rigidity allows for much cleaner cyclic and collective pitch changes, making the helicopter more predictable in wind.

• Premium Scale Look: The polished metallic finish adds a high-end, professional look to your scale.

Compatibility

Install Tips

• Thread Locker is Mandatory: Because this is a metal-on-metal assembly, you must use a tiny drop of blue thread locker on all screws to prevent them from vibrating loose.

• Spindle Alignment: Ensure the feathering shaft slides through the metal head smoothly; do not force it if there is any resistance.

• Balance Check: After installation, re-check your blade tracking. The increased rigidity of the metal head makes accurate tracking even more important for a smooth hover.
