From the old Tech Notes:

"The Fun-One is a aerobatic sport plane designed to be competitive at fun fly events even in the hands of average sport pilots. Its light weight permits fast climbs and long glides. Low wing loading enables trainer-like slow landings. Combination aileron/flap set-up great for use with the mixing capabilities of computer radio. High-quality balsa, ply, and basswoods hold up to the rigors of sport and fun flying.

The Fun One is ideal for use with flaperons, elevator/flap and aileron-rudder mixing, and other controls permitted by computer radios.
