DU-BRO 3-Blade Spinner – Easy, Safe RC Prop Spinner with Adapters

The DU-BRO 3-Blade Spinner is the perfect upgrade for RC pilots who want a clean, balanced, and safe propeller setup for their three-bladed prop. Designed for both ease of use and dependable performance, this spinner installs quickly and securely—making it ideal for sport, scale, and glow-powered aircraft.

Each spinner comes with five shaft adapters (5mm, 6mm, 1/4", 7mm, 5/16"), allowing it to fit a wide range of motors and engines without drilling or modifying the back plate. Everything you need is included in the package, so installation is fast and frustration-free.

One of the standout features of DU-BRO’s 3-Blade Spinner is its nylon insert lock nut system. This clever design securely attaches the spinner cone to the back plate, preventing loosening and reducing vibration during flight. It provides a strong, reliable hold that stays tight even during high-RPM operation, ensuring your model flies safely and smoothly.

These spinners are available in three popular sizes:

• 2" (50.8 mm) – 29 g

• 2.5" (63.5 mm) – 44 g

• 3" (76.2 mm) – 65 g

This range makes it easy to choose the ideal size for your airplane’s propeller and nose profile.

The DU-BRO 3-Blade Spinner is perfect for:

• Scale aircraft needing three-blade props

• Sport models requiring smooth, low-vibration performance

• Glow or electric airplanes

• Pilots who want a clean, professional-looking prop setup

Made with DU-BRO’s well-known quality, this spinner is engineered for long life, easy installation, and safe operation.
