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.
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.
