Precision Aluminium Folding Propeller Hub – Ø45 mm Spinner, 4 mm Motor Shaft (ESPW45-4)

The ESPW45-4 Precision Aluminium Folding Propeller Hub is a headless folding propeller spinner engineered for reliable and efficient power transmission in RC aircraft propulsion systems and compact rotary drive applications.

Manufactured from precision-machined aluminium alloy, this hub provides excellent strength-to-weight performance, corrosion resistance, and dimensional accuracy. The 45 mm outer diameter ensures smooth airflow integration on folding propeller setups, while the 4 mm motor shaft bore allows secure mounting on compatible brushless motors.

This folding propeller hub is widely used in RC airplanes, electric gliders, UAV propulsion prototypes, and can also be applied in educational, research, and experimental engineering projects where lightweight rotating components are required.

Designed for builders who value mechanical precision, balance, and clean integration, the ESPW45-4 supports stable folding-prop operation and consistent rotational alignment.
