This ultra-light aircraft is the perfect fusion of 3D/4D excitement and F3P precision, offering an extraordinary flying experience. The goal with the Devil Ray was to create an aircraft that embodies the best of both blends 3D/4D and F3P (Indoor Aerobatic Model Aircraft) competition planes that are ultra-lightweight, high-precision aircraft designed to fly in confined indoor spaces like gymnasiums or sports arenas. They are built to execute complex, slow-speed aerobatic 3D and 4D maneuvers with extreme exactness. The Devil Ray meets F3P competition rules (max weight under 300g) with a rigid foam structure covered with transparent UV-Film and a flying weight of only 210g! The larger control surfaces provide superior control authority, while the elongated fuselage enhances maneuverability and stability during slower F3P-style flights. This aircraft opens the door to the exhilarating world of reverse-facing 4D flying, delivering not just a sense of achievement but also an undeniable wow factor.
