4.7 cm 3-Blade Propeller

For building small fans, toys, miniature airplanes, and student projects, various types of propellers are required. Each propeller can have different numbers of blades, and choosing the correct size and blade count is important, as it directly affects airflow and the movement speed of the device.

3-blade propellers offer advantages over two-blade designs, including quieter operation and a more compact size. Additionally, 3-blade propellers are often preferred over four-blade versions because fewer blades create less resistance against wind or air, improving efficiency.

Propellers require motors to operate, and the shaft size is a crucial factor. The inner shaft diameter of this propeller is 1.97 mm, and the outer shaft diameter is 4.85 mm.

This 4.7 cm 3-blade propeller is made of blue plastic and is ideal as a small fan blade or for lightweight DIY applications.
