2.4G Main Receiver Board Circuit Module Component for SU57 RC Plane

Eliminate Aggressive Swashplate Slop and Resolve High-RPM Drive Vibration Issues

Worn, gritty, or binding main frame bearings create dangerous play along your scale helicopter’s main drive shaft, resulting in poor altitude hold tracking, aggressive shaking during high-speed flips, and premature main gear tooth wear. When factory-grease becomes contaminated with track dust or dried up over dozens of aggressive 3D stunt sessions, the internal balls will seize, dragging down your brushless motor performance and severely reducing flight run times. For the detailed 1:25 scale RC ERA C180 BO105, maintaining an ultra-smooth, wobble-free central shaft is a necessity for stable multi-blade scale tracking. This original C189 main frame ball bearing pack drops directly into your aluminum or composite frame slots, completely restoring a buttery-smooth rotational axis and locking down your swashplate stability. Ships worldwide.

Product Highlights

• Dual-Bearing Matching Pair Configuration: Pack includes two perfectly matched, high-precision radial ball bearings to refresh both the upper and lower main shaft support seats simultaneously.

• Double Metal-Shield Dust Barrier: Precision fitted with heavy-duty side shields that effectively seal out microscopic carpet hair, dust, and dried grease to maintain clean internal ball rotation.

• High-Speed Industrial Chrome Steel Construction: Crafted from high-density, wear-resistant steel alloy rings and balls engineered to endure the rigorous radial loads of advanced 3D stunt flying.

• Ultra-Low Drag Factory Pre-Lubrication: Pre-packed at the assembly line with low-viscosity synthetic synthetic high-speed oil, minimizing thermal buildup and lowering friction coefficients.

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 Bearing Set

Install Tips

• Chassis Split & Upper Bearing Extraction: Use your precision maintenance phillips screwdriver to remove the scale fuselage hull screws and unbolt the internal skeleton structure; carefully pull the steel main rotor shaft upward through the top bearing housing and clear away any residual black drive gear shavings.

• Lower Frame Pocket Placement: Slide the new lower frame bearing squarely into the dedicated pocket directly beneath your principal brushless motor gear platform; ensure it sits completely flush on its collar shoulder so the main drive shaft does not experience vertical shifting.

• Parallel Shaft Insertion and Alignment Verification: Pass your hardened steel main rotor shaft down vertically through the center bores of both freshly seated bearings; the shaft must turn effortlessly by hand with zero friction hitching before you re-attach your 6-channel linkages and swashplate arms.

• Pre-Flight Mechanical Torque Inspection: Re-clamp your main collar locking hardware package snugly over the inner bearing rings; spin your multi-blade rotor assembly by hand on your dual-use practice pad to confirm that all axis drag has vanished before initializing your radio controller binding sequence.
