Tail Rotor Blade Set with Screws for YuXiang F112S AH-1 Cobra RC Helicopter

Restore Tail Authority and Heading Stability

A chipped or unbalanced tail rotor is the leading cause of "tail wag" and poor heading hold during precision GPS flight. For the YuXiang F112S 32:1 scale AH-1 Cobra, the tail rotor must work perfectly with the dual brushless motor system to counteract main rotor torque. This replacement tail rotor blade set solves the problem of unstable yaw control, ensuring your Cobra maintains a rock-solid heading even during complex scale maneuvers.  Ships worldwide.

Product Highlights

• Complete Replacement Kit: Comes as a comprehensive set including two high-efficiency tail blades and two precision hex socket cap screws for a total refresh.

• Durable Composite Construction: Engineered from high-strength, lightweight materials to withstand high-RPM tail motor speeds without deforming.

• Optimized Blade Profile: Specifically designed to provide maximum thrust for the F112S tail motor, resulting in crisp and responsive yaw inputs.

• Scale Appearance: Finished in matte black to seamlessly integrate with the authentic 32:1 scale military look of the AH-1 Cobra.

Compatibility

For the YuXiang F112S 9CH GPS RC Helicopter only.

What’s in the Box

• 1 x YuXiang F112S Tail Rotor Blade Set

Install Tips

• Tail Blade Mounting: Align the center hole of the tail blade with the tail motor shaft hub; ensure the aerodynamic leading edge is oriented correctly for counter-clockwise rotation.

• Hex Screw Fastening: Use the included hex socket cap screws to secure the blades; tighten until snug but avoid over-torquing to prevent stripping the motor hub threads.

• Vibration Check: After installation, spin the tail rotor manually to ensure it is centered and tracks straight; a wobbly tail rotor can cause electronic interference with the GPS flight controller.

• Hardware Inspection: Periodically check the tightness of the hex screws, as the high vibration frequency of the tail motor can occasionally loosen hardware over time.
