RC Motor Propeller, 3Vane, 50 mm Rotating Diameter Product overview This three vane propeller is designed as a direct replacement for small electric RC boats and DIY marine projects. Its compact 50 mm rotating diameter and lightweight construction make it suitable for hobby use and prototyping. Please check the rotating diameter and shaft size before installation. Key benefits Straightforward replacement for RC boats and small watercraft motors, restoring propulsion without complex modifications Three vane design helps maintain stable thrust and smoother water flow for predictable handling Lightweight yet durable plastic and metal construction balances responsiveness and longevity Easy installation on compatible motors with a 2 mm shaft hole Compact 50 mm rotating diameter keeps compatibility with micro and smallscale setups where space is limited Important specifications Number of vanes: 3 Rotating diameter: 50 mm Material: Plastic and metal Net weight: 23 g Main color: Red, silver tone Rated voltage: DC 3V Output speed: 6500 RPM Current draw: 0.13 A Motor shaft hole diameter: 2 mm 0.08 inch Package contents: 1 x RC motor propeller Compatibility and fit Designed for motors and drives that accept a 2 mm shaft and operate around DC 3V Verify the 50 mm rotating diameter and shaft fit against your hull and drivetrain to avoid interference Suitable as a replacement part when original propellers are worn, damaged, or missing Practical use scenarios a damaged propeller on a small RC boat to restore water performance during weekend hobby sessions Install in a custom micro boat build or student engineering project where compact propulsion is required Swap propellers for prototype testing to compare handling characteristics without changing the motor Installation tips Confirm the shaft diameter and rotating clearance before fitting Secure the propeller to the motor shaft following your motor or hull mounting method Inspect for balance and rotation after installation to reduce vibration This propeller is supplied as a single unit and is intended for hobby and light duty applications where the listed dimensions and electrical ratings are met.
