Walter Good was the only contestant who attempted a controlled
flight in the face of the 20mph winds. Even though it ended
in a crack-up, Walt was awarded first place. A truly convincing
demonstration of R/C flight by a powered miniature aircraft
would have to wait until the following year.
Eleven R/C fliers showed up at the 1939 Nationals at the
Detroit Wayne County airport. For the first time, a 100-point
system was adopted by the judges. Points were given for
craftsmanship, actual R/C operation in a static preflight
mode on the ground and a variety of flight maneuvers.
That was a rewarding year for Walter and William Good, 23-
year-old twins from Kalamazoo, Michigan. Bill was a licensed
ham-radio operator with the call letters W91FD.
Their aircraft, named K-G, was a slightly modified, high-wing
monoplane. (See the K-G story in the January '91 issue of
Model Airplane News.) This first stable gas model was designed
by a former editor of Model Airplane News- Charles Hampson
Their radio and control mechanisms were the essence of simplicity.
At a time when all of their competitor's planes carried
receivers with 3- and 4-tube circuits, the Good brothers'
radio receiver was a one-tube affair with a minimum of electrical
components. Their homemade relay was so sensitive that it
could be activated by a current change of 1/2 milliamp!
