A set of 4 Gemfan propellers strengthened with nylon glass fiber. The rigidity of these nylon glass fiber propellers is the perfect balance between the flexible ABS plastic props and the more rigid carbon nylon props. They come in a 2 blade style with a 5mm center hub.
A good prop for small planes and multi-rotors.
- 2x 5x4 CW, 2x 5x4 CCW with 5mm ID hub
