Balsa aircraft are lightweight model airplanes made primarily from balsa wood, a soft and buoyant material. These models are popular among hobbyists and educators for their ease of construction and flight. Balsa wood's low density allows for the creation of intricate designs while maintaining a strong structure, making it ideal for both indoor and outdoor flying. Typically, balsa aircraft can be powered by rubber bands, electric motors, or even gliding without any propulsion. They are often used in aerodynamics experiments and competitions, helping enthusiasts learn about flight principles and design. Building and flying balsa aircraft can be an enjoyable and educational experience for all ages.
