Main Rotor Blade Propeller Set for RC ERA C190 Brushless Helicopter 

The Foundation of Vertical Stability

The main shaft is the backbone of your helicopter; even a microscopic bend can cause devastating vibrations that confuse the 6-axis gyro and Optical Flow sensors. This official main shaft set solves structural drive issues, ensuring your C190 rotates on a perfectly true axis for maximum efficiency and a rock-solid hover. Ships worldwide.

Product Highlights

• Hardened Stainless Steel: Built to withstand the torque of the C190's brushless motor while resisting permanent deformation during rough landings.

• Pre-Drilled Mounting Points: Features factory-precision holes for the main gear pin and rotor head bolt, ensuring perfect timing and alignment.

• Micro-Polished Finish: Designed to slide through main frame bearings with minimal friction, reducing heat buildup and extending flight times.

• Full Assembly Compatibility: Designed to integrate seamlessly with the C190 swashplate and locking collar for a gap-free installation.

Install Tips

• Locking Collar Tension: Position the locking collar so there is zero vertical "play" in the shaft, but ensure it can still spin freely without binding.

• Pin Inspection: When installing the main gear onto the shaft, check that the retaining pin is centered and not rubbing against the frame.
