Steel Main Rotor Feathering Shaft Axle Spindle Set for RC ERA C170 Apache

Eliminate Horizontal Blade Grip Wobble, Prevent Violent Stunt Tracking Splits, and Secure High-RPM Core Gyro Alignment

The feathering shaft (horizontal spindle axle) is the foundational support core that bears the massive centrifugal pulling forces of the spinning rotor blades. In 3D stunt mode, executing rapid negative-to-positive pitch transitions and inverted loops creates intense bending stress at the blade grip pivot point. If your horizontal spindle shafts become microscopically bent or loose due to continuous aerobatic strain, the rotor blades will develop lateral play and vertical tracking splits. For the 1:48 scale RC ERA C170 Longbow Apache, this mechanical slop causes heavy airframe vibration, cuts down your collective punch, and destabilizes the flybarless flight control system. Replacing your strained components with this factory-fresh, hardened steel feathering shaft set completely eliminates lateral blade grip play, restores crisp mechanical pitch execution, and ensures stable, arrow-straight tracking planes during extreme 3D maneuvers.  Ships worldwide.

Product Highlights

• Hardened Torsional-Resistant Steel Construction: Specially treated to withstand continuous structural compression and high centrifugal loading without bending under intense 3D stunt loads.

• Integrated Hexagonal Step Shoulder Alignment: Machined with an integrated hex positioning collar on each shaft to seat perfectly inside the aluminum rotor head hub, guaranteeing a centered and rock-solid rotational alignment.

• Dual-Threaded Low-Tolerance Micro Pins: Features clean, high-pitch micro threads on both ends of the shaft pins to ensure a perfect, slop-free fit with your stabilization mechanics.

• Complete 4-Shaft Overhaul Pack with Slotted Lock Nuts: Comes as a complete matching set including 4 heavy-duty steel feathering shafts and 4 specialized slotted retention nuts to refresh all four rotor grips simultaneously.

Compatibility

For the RC ERA C170 1:48 Scale Longbow Apache RC Helicopter only.

What’s in the Box

• 1 x RC ERA C170 Feathering Shaft

Install Tips

• Extracting the Defective Spindle Shafts: Remove the main rotor blades; use your tools to back out the slotted lock nuts from the side of the blade grips, then slide the worn horizontal feathering shafts out from the center aluminum rotor head core.

• Seating the Hex Step Flange Shroud: Slide the new steel feathering shaft into the horizontal sleeve of the metal rotor head core; ensure the integrated hexagon step shoulder guides slide fully home into their indexed slots on the head hub for proper centering alignment.

• Assembling Blade Grips and Slotted Retention Nuts: Push your main blade grips over the exposed shaft ends; carefully thread the included specialized slotted lock nuts onto the micro-threaded ends of the shaft pins, applying a tiny drop of medium thread-locker to prevent them from backing out under high-RPM flight vibrations.

• Symmetry Check and Pre-Flight Tensioning: Tighten the lock nuts evenly on both sides until the blade grips rotate smoothly with zero lateral play; spin the entire 4-blade assembly by hand to confirm friction-free mechanics before throttling up into high-load 3D stunt inversions.
