Thanks John.

My Mambo is not the oldest RC airplane I have. I have a Berkeley Super Buccaneer that was built in the late 40's that was set-up for escapement rudder. A lot of the early RC airplanes were just large free flight designs with big cabin areas. It would have had a tube radio, and seems to have had an ignition engine as well.

It was given to my dad while he was in high school (Manhattan Ks), but he no longer remembers who built it. A few years ago I met Carl Schwab who was the designer of the Dee Bee Quadruplex radio back in the early 60's at a trade show. Carl graduated from Kansas State University (BS in Electrical Engineering) in Manhattan at about the same time my dad was in HS. Carl thought that the Buccaneer was built by a guy that owned a local gas station at the time, but also didn't remember the guys name.

For those who may no know what a Super Buccaneer was, it was a free flight design from 1939 with a 8 1/2 foot wing span that used up to a .99 sized engine. As such, it could also carry several pounds of batteries required for crude radios and ignition systems for low rpm engines from the era.
