STX 43 mm Stainless Steel Propeller is a high-performance two-blade propeller designed for RC boat applications that require reliable thrust, smooth hydrodynamics, and consistent behavior at high RPM.

The STX series emphasizes optimized blade profile, hub strength, and edge design to provide stable acceleration, reduced cavitation, and predictable handling across a range of motor setups. This propeller geometry is suitable for both single-prop and twin-prop configurations where balanced performance and smooth water flow are required.

Each STX propeller is dynamically balanced for high-speed use and finished with precision polishing to ensure smooth, vibration-free performance. Manufactured from durable stainless steel, this propeller offers excellent strength and long-lasting performance in both fresh and salt water environments.
