FUN-FLY PROJECT The Fun-Fly project was born from the vision and experience of Engineer Michelangelo Antonelli, a name that represents innovation, research, and passion in the world of aviation. Antonelli, known for designing and building high-performance aircraft, has always believed that flying should be accessible to everyone, especially young people. With this philosophy in mind, he created a truly unique aircraft capable of combining aerobatic performance with uncompromising safety. In the 1990s, Fun Fly 3D model aircraft took the world of radiocontrolled flight by storm thanks to their extraordinary maneuverability and ability to perform extreme aerobatics at low speed. Inspired by these models, Engineer Antonelli developed an ultralight kit aircraft aimed at young pilots, maintaining the same agility and responsiveness while paying meticulous attention to safety and ease of assembly. Project Objectives The Fun-Fly project, developed by the Italian company AVIO-SMA, pursues three main objectives: • Extremely high safety • Low flight speeds and exceptional low-speed maneuverability • An aircraft within everyone's reach, designed to be easily built and flown After an extensive research and development phase, including the testing of innovative materials such as honeycomb Nomex composite boards with carbon fiber layers and 4130 steel structures, the final construction material chosen for the aircraft was aluminum alloy. This material proved to be the ideal solution, offering the perfect balance between strength, lightness, and long-term durability. State-of-the-Art Production Building this aircraft requires very few tools: a riveter and a simple toolbox with wrenches and hex keys. The kit is so intuitive to assemble that it recalls the old Meccano sets many of us played with as children, perhaps with our dads. Assembling the Fun-Fly is a hands-on and rewarding activity that brings back the authentic joy of "working with your hands," making the entire process accessible even to those without much experience. This project is designed to be simple, practical, and also satisfying at every step, as the aircraft comes to life piece by piece. All components of this aircraft are manufactured using CNC machines. The entire production process is regulated by an ISO 9001 certified structure, ensuring the use of cutting-edge manufacturing and control technologi

Each stage of the build is subject to rigorous strength and quality tests, carried out directly in SMA’s laboratories, ensuring every component meets the highest standards of safety and reliability. Thanks to this top-tier production process, the FunFly offers uncompromising structural reliability, reaffirming AVIO-SMA's commitment to producing innovative and high-quality aircraft. The AS993 Engine: Power and Performance Without Compromise One of the defining features of the Fun-Fly Extreme is the AS993 engine, a two-stroke twin-cylinder powerplant developed directly by AVIO-SMA to guarantee...

Thanks to this innovative solution, the Fun-Fly can be assembled in a very short time, allowing any enthusiast to quickly transform a set of components into a real aircraft ready for takeoff. Structure Designed for Maximum Loads The Fun-Fly's airframe has been engineered to ensure exceptional structural strength, enabling the aircraft to safely handle highload maneuvers. The entire structure is rated to withstand working loads of +6G and -3G at 300 kg, making it perfect for aerobatic flight and ensuring safety margins beyond the standards required for ultralights. This means that the Fun-Fly...

The control stick offers a wide range of movement, giving the pilot direct and precise control that enhances the joy of flight. The overall feeling once onboard is like being at the controls of a World War II fighter plane. Adding to this experience is the special two-blade propeller, approximately 2.5 meters in diameter, which ensures powerful and responsive thrust at takeoff. In the 65 HP version, the thrust is already thrilling, but with the 135 HP engine, takeoff becomes breathtaking, delivering acceleration that leaves a lasting impression. Conclusion The Fun-Fly is not just an aircraft;...
