Gemfan 18X10X3 propellers, 3-blade, glass-filled nylon, (set CW - 1 pc, CCW - 1 pc)

Gemfan 18X10X3 - a high-performance, large-diameter three-blade propeller designed for heavy multicopters, industrial UAVs and FPV platforms operating with a large payload. With a diameter of 18 inches and a pitch of 10 inches, the propeller provides powerful and stable thrust, high efficiency and reliable operation during long flights.

The blades are made of Glass Fiber Reinforced Nylon, which combines high rigidity, strength and resistance to deformation even under significant loads.

The design is optimized for drones with a wheelbase of about 1300 mm and a take-off weight of 11-13 kg. Thanks to the three-blade design, the propeller provides uniform airflow, improved flight stability and efficient thrust transfer.

The model is recommended for use with 5330 class brushless motors, ensuring reliable operation of the power plant even in harsh operating conditions.
