Gemfan 17X8X3 propellers, 3-blade, glass-filled nylon, (set CW - 1 pc, CCW - 1 pc)

Gemfan 17X8X3 - is a high-quality, large-diameter three-blade propeller designed for heavy multicopters, industrial drones and FPV platforms operating with a large payload. With a diameter of 17 inches and a pitch of 8 inches, the propeller provides powerful, stable thrust, high efficiency and smooth flight even at maximum load.

The blades are made of Glass Fiber Reinforced Nylon, which combines high rigidity, low weight and resistance to deformation. The material withstands significant aerodynamic loads, vibrations, and long-term operation.

The propeller design is optimized for quadcopters with a wheelbase of about 780 mm and a take-off weight of 10-12 kg. The three-blade configuration creates a more uniform airflow, improves controllability and allows for high thrust at moderate engine speeds.

The model is recommended for use with 5330 class brushless motors, which ensures efficient power transfer and stable operation of the power plant.
