The GEMFAN D90 is a 3.5-inch penta-blade (5-blade) propeller designed specifically for ducted FPV systems and cinewhoop platforms that require high static thrust, smooth airflow, and stable control. With a 2.4-inch pitch and five-blade configuration, it delivers strong lift and excellent efficiency at lower RPMs—ideal for cinematic flying and controlled indoor or close-proximity operation.

Constructed from durable polycarbonate (PC) and weighing approximately 3.5g per propeller, the D90 provides the rigidity and durability needed for ducted environments while maintaining smooth, predictable throttle response.
