The balsa model U-Control Fireball is the plane that pioneered the Control Line flying craze.
This was the first mass produced balsa model airplane kit to offer the immediate hands-on control of the model plane by two flying wires. The Fireball has a colorful and memorable past, and is still considered to be a model of beautiful styling and design. Also, here you can see Jim Walker performing his famous Sabre Dance with his two-speed ignition engine Fireball. Check out the "Brief History of the Fireball"
