FMS 1300mm PA-18 3536 Motor Shaft For 1400mm Kingfisher, 1300mm PA-18, 1020mm F3A

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.

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.

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.

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.

(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.
