RC ERA A61 Optical-Flow RC Helicopter Main Shaft Set - Replacement Spare Part

Eliminate Vibration and Restore Smooth Flight Performance 

A bent or damaged main shaft is the primary cause of severe vibration, unstable hovering, and erratic optical flow positioning in micro helicopters. This official RC ERA A61 Main Shaft set is designed to replace wobbling or stressed shafts that occur after a hard landing. By ensuring a perfectly straight rotation of the rotor head, this replacement part eliminates mechanical jitter, allowing the altitude hold and optical flow systems to function with factory-standard precision. Ships worldwide.

Product Highlights

• High-Strength Carbon Steel Construction: The main rod is crafted from reinforced steel to resist bending during high-speed rotations and minor impacts.

• Precision-Toleranced Collar: Includes a perfectly sized mounting collar that ensures the shaft remains vertically secure, preventing "up-and-down" play in the rotor system.

• Seamless Gear Integration: The shaft diameter is specifically calibrated to fit the A61 main gear and swashplate, ensuring zero-latency power transfer from the motor.

Compatibility

What’s in the Box

• 1* Main Shaft Set

Install Tips

• Shaft Alignment: When sliding the steel shaft through the bearings, ensure it moves freely without resistance; if you feel friction, check the internal bearings for damage.

• Collar Securing: Secure the white mounting collar tightly to eliminate vertical play; even a small amount of vertical movement can cause the helicopter to drift while using altitude hold.

• Linkage Check: After replacing the shaft, re-verify the levelness of the swashplate and the tightness of the rotor blade screws to ensure a safe first flight.
