Gemfan Floppy Proppy F5135 2-Blade Propeller (Set of 4 — 2CW+2CCW)

The Gemfan Floppy Proppy F5135 is a folding 5.1-inch 2-blade propeller engineered for 5-inch long-range cruisers and lightweight cinematic builds. Unlike standard rigid props, the polycarbonate blades are mounted to a central hub and can swing backwards upon impact. This folding mechanism prevents blade snapping during hard strikes and allows you to fold the props parallel to the arms, drastically reducing the drone's footprint for transport.

Key features

• Folding 2-blade design mitigates crash damage and reduces transport volume
• Low-drag 3.5-inch pitch optimized for cruising efficiency and extended flight times
• Compatible with standard M5 threaded motor shafts
