Armstrong APF 1675 Front Foil

The APF front foil is all about maximizing your flight time. It achieves such remarkable low speed lift and cruising efficiency thanks to a combination of its outline and foil section. The nearly straight leading edge, forward swept trailing edge and wide wingspan boost glide. The APF's foil section itself is high camber and relatively thick for excellent low end lift from very slow speeds, and it optimized specifically for low speeds so you can conserve energy while pumping at a relaxed cadence. Downturned wingtips reduce drag, further improving your potential to go the distance.
