KALAMAZOO, Mich. — Guests visiting the Air Zoo can now learn all about the world’s first successful radio control aircraft — the Guff.
The Guff was the first R/C aircraft created with vacuum tube-based control units. Walter and William Good, who were from Kalamazoo and attended Kalamazoo College, built the model and won first place in the 1939, 1940, and 1947 R/C Airplane Nationals.

“The Air Zoo is honored to feature a display that pays tribute to the Good brothers and their contributions to aviation,” said Bob Ellis, Air Zoo president and CEO.
The Air Zoo’s Guff display features a replica built and donated by Walter Pompey, from Kalamazoo, along with a radio transmitter, biographies of the Good brothers, and a video of their flights.
The Good brothers’ original Guff is on display at the Smithsonian National Air and Space Museum.
