Main Rotor Head Center Canopy Cap Cover with Screw Set for RC ERA C180（Military Green/Yellow）

Safeguard Your Core Rotor Mast Assembly and Streamline Aerodynamic Airflow

A missing, cracked, or loose central rotor cap exposes the main mechanical shaft locking pins and center threads to aggressive debris, dust, and moisture during field maneuvers. For the RC ERA C180 1:25 scale BO105 helicopter, keeping the fast-spinning center hub aerodynamically clean is crucial to preventing unnecessary rotational drag during inverted 3D stunt tracking. This factory-original plastic rotor head cap assembly solves the issue of exposed center linkages, keeping dirt entirely out of your vital flybarless control core while preserving the realistic, flush-top military appearance. Ships worldwide.

Product Highlights

• Matched 2-Piece Core Protection Set: Packed efficiently with exactly 1 molded black plastic dome cap and 1 factory-fitted silver center lock screw.

• Ultra-Lightweight Balanced Polymer: Injection-molded from a high-impact, low-mass composite compound that shields the mechanical core without adding rotating top-heaviness to the mast.

• Low-Drag Aerodynamic Form Factor: Features a beautifully smooth, rounded dome curvature designed to cleanly split incoming airflow and eliminate air pockets around the rotating head during high-velocity aerobatics.

• Recessed Center Locking Bore: Engineered with a deep, pre-molded center structural cavity

Compatibility

For the RC ERA C180 1:25 Scale BO105 6-Channel Brushless RC Helicopter only.

What’s in the Box

• 1 x RC ERA C180 Rotor Head Cap Set（Military Green/Yellow）

Install Tips

• Debris & Stem Inspection: Clean out any residual dust, dried grease, or sheared plastic fragments from the top mounting cavity of your central 4-way metal rotor head hub.

• Cap Seat Indexing: Place the black plastic dome cap squarely over the dead center of the main rotor hub core; twist it slightly until the internal alignment columns slide flush and interlocking onto the top of the main shaft stem.

• Silver Center Screw Fastening: Drop the included silver retention screw straight through the top center bore of the plastic dome; apply a tiny trace of threadlock onto the threads and tighten it down snug into the main mast using a precise cross-slot driver.

• Frictionless Clearance Verification: Spin the 4-blade rotor assembly manually by hand to verify that the newly mounted cap sits perfectly centered, spins completely true without tracking wobble, and leaves zero friction contact against the surrounding blade grip link arms before taking off.
