Frequently Asked Questions
Which aircraft and motors is this motor shaft compatible with?
This motor shaft is designed specifically for the FMS 3536-series brushless outrunner motor. It is compatible with the following three fixed-wing aircraft: 1400mm Kingfisher, 1300mm PA-18, and 1020mm F3A. Please verify that your motor is a 3536-size brushless outrunner. Other motor sizes (e.g., 3530, 3542) are not compatible.
What material is this motor shaft made of, and what are its specifications?
This motor shaft is manufactured from high-strength alloy steel with a hardened surface treatment, offering excellent wear resistance and torsional strength. Its dimensions match the factory-original FMS 3536 motor shaft exactly, ensuring precise fitment with both the motor rotor and propeller collet adapter.
Under what circumstances should I replace the motor shaft?
Replace the motor shaft if any of the following conditions occur: (1) The shaft is bent or deformed after a crash or hard landing; (2) The shaft is damaged due to propeller impact with foreign objects; (3) Visible wear or increased play develops after extended use; (4) Abnormal vibration or noise persists during motor operation after ruling out bearing issues. Warning: A bent motor shaft must be replaced. Continued use will cause excessive wear on motor bearings and may lead to motor failure.
What is included in the package?
This is a single replacement motor shaft only. The package contains one (1) 3536 motor shaft. It does not include the propeller collet adapter, mounting screws, E-clip/retaining clip, or any other hardware. Please reuse the original components from your motor for installation.
What should I pay attention to when replacing the motor shaft?
(1) Take photos of the original assembly order and component orientation before disassembly. (2) Ensure the motor shaft is concentric with the rotor during installation — avoid angular misalignment. (3) After installing the propeller collet, check for axial play (fore-aft movement). (4) Manually rotate the motor shaft after installation to verify smooth, noise-free operation. (5) Always confirm the propeller is securely tightened before the first power-up to prevent propeller throw.

Description
Replace a bent or damaged motor shaft and restore smooth, vibration-free power to your FMS aircraft. This is the official OEM replacement 3536 motor shaft for the FMS brushless outrunner motor, compatible with three popular fixed-wing platforms: the 1400mm Kingfisher, 1300mm PA-18, and 1020mm F3A.
A bent motor shaft is one of the most common crash consequences — and one of the most important to address before your next flight. Even a slight bend causes excessive bearing wear, abnormal vibration, and reduced motor efficiency. This factory-spec replacement shaft restores precise concentricity and gets your motor running like new.

- FMS 1020mm F3A — 3536-series brushless outrunner motor
⚠️ Important: This shaft is designed for the FMS 3536-size motor only. Other motor sizes (e.g., 3530, 3542) are not compatible. A bent motor shaft must be replaced before flight — continued use will accelerate bearing wear and may cause motor failure.
Note: Package includes one (1) motor shaft only. Propeller collet adapter, mounting screws, and retaining clip are not included — reuse original hardware from your motor.
