This is a GemFan 5x3R Reverse Rotation Propeller. GemFan produces high quality propellers for Airplane and Multi-Rotor craft use. These props are made from ABS plastic with a glass fiber fill for extra rigidity and durability. "Reverse" rotation is counter clockwise.
The 5x3 props have a 5mm hole drilled in the hub, so they are ready to bolt on most 22mm motor prop adapters. The hub measures 6mm thick, with an 11.5mm diameter. If you have a larger threaded shaft on your prop adapter, the center hole can be reamed out to 6mm or 1/4 inch as needed.
