In the mid-1940s, from the age of 15 to 17, Marshall Green was three times Canadian National model airplane champion, setting some amazing records as shown in these vintage newspaper articles.
In 1946, he, together with Jack Luck, the famous Canadian industrial designer, fabricated a working radio control sender and receiver in 1946. Likely one of the first if not the first RC unit that successfully controlled a model airplane. It worked wonderfully, controlling the rudder, stab, and engine revs of a large model plane named “The Big Yellow Job.”
