Gemfan Vortex 7x15 (2 pcs)

Gemfan Vortex 7x15 are two-blade propellers with an extreme 15" pitch, suitable for fast RC airplane models and high-speed 7" quadcopters. The high pitch provides strong forward thrust and a high top speed. The propellers are made from glass fiber-reinforced nylon, which retains its shape even under heavy load. The blade profile is designed using CFD simulations, thin blade tips reduce noise and tip vortices, and the matte leading edge improves efficiency at high RPM. Each piece undergoes dynamic balancing. The center hole measures 6.35 mm, and the included adapter rings allow installation on 3, 4, 5, 6 and 7 mm shafts. In the manufacturer's static test with a 3214 800KV motor at 22.2V, the propeller achieved 915 g of thrust at a current draw of 52.6A.

The propellers are supplied in packs of 2 pcs according to the selected variant (E – standard rotation, R – reverse rotation).
