Feathering Shaft Set with Washers for YuXiang F112S GPS RC Helicopter

Eliminate Rotor Head Wobble and Maintain Flight Safety

A bent or worn feathering shaft is a hidden culprit behind severe blade tracking issues, high-frequency rotor vibrations, and unpredictable stabilization failures. For the YuXiang F112S 32:1 scale AH-1 Cobra, the horizontal spindle must stay perfectly straight to handle the immense centrifugal force of the main blades during dual brushless, 9CH GPS flight. This complete feathering shaft set solves the issue of loose rotor grips and violent mechanical wobbling, ensuring your helicopter flies smoothly with maximum safety.  Ships worldwide.

Product Highlights

• Premium Steel Spindles: Includes two ultra-rigid, high-tensile steel feathering shafts designed to resist bending under heavy load or hard impacts.

• Complete Gasket & Washer Package: Comes equipped with two specialized brass fixed washers and two steel washers to eliminate axial play in the rotor grips.

• Factory-Spec Hex Screws: Features two precise hex socket cup screws coated for secure thread engagement into the horizontal shaft ends.

• Zero-Gap Alignment: Engineered exactly to factory specifications to secure the blade grips tightly against the rotor head hub without binding.

What’s in the Box

• 1 x  YuXiang F112S Feathering Shaft Set

Install Tips

• Feathering Shaft & Screws: Slide the steel spindle through the main rotor head hub; apply a drop of medium threadlocker (blue Loctite) to the hex cup screws before locking down the blade grips.

• Brass Fixed Washers: Place the stepped brass fixed washers correctly against the internal rubber dampeners; the raised side must face toward the bearing to ensure smooth, unhindered pivot action.

• Flat Steel Washers: Ensure the silver flat washers are installed between the screw head and the outer edge of the blade grip bearing to distribute fastening pressure evenly.

• Play Check: After fully tightening the screws from both sides, pull outward on both blade grips; they should rotate smoothly without any clicking or gritty feeling, and there should be zero horizontal play.
