Gemfan produces some of the finest props for RC use. The APC Style Glass fiber nylon series propellers offer a wide selection of sizes for Model Aircraft applications. Gemfan propellers are designed using CATIA and select airfoil profiles with low Reynolds numbers through the NACA airfoil profile database.

The blades on these props feature an elliptical blade shape that produces a more uniform thrust distribution across the entire blade surface for maximum lift and thrust efficiency. The standard props are made from Nylon with a glass fiber fill for extra strength and durability, suitable for outrunner motors.
