Model aviation refers to the hobby of building and flying miniature aircraft, which can be powered by engines or flown as gliders. Enthusiasts often create detailed replicas of real aircraft, and these models can vary in size from small hand-held versions to larger, radio-controlled planes. Participants in model aviation often join clubs or organizations, where they can share their passion, learn new skills, and participate in competitions. Events may include races or showcases, allowing hobbyists to demonstrate their flying abilities and the craftsmanship of their models, fostering a sense of community among model aviation enthusiasts.
