These pages from vintage modeling magazines like Flying Aces, Air Trails, American Modeler, American Aircraft Modeler, Young Men, Flying Models, Model Airplane News, R/C Modeler, captured the era. All copyrights acknowledged.

Flying model helicopters of any sort were fairly rare in 1952, when this edition of Air Trails magazine hit the news stands. The sophisticated, miniaturized, smart stabilization systems of today's models were not available at any price, and radio control was the realm of military research vehicles. Methods for driving the rotors included glow and gas engines, rubber bands, and even Jetex engines. Many free flight helicopters sported the JETicopter's arrangement of a pair of engines at the end of a moment arm which caused rotation. Cox .010 and .020 engines were a popular choice, as were the Jetex engines. I always wondered what happened when one engine quit, resulting in asymmetrical thrust. It probably caused a few moments of consternation as the craft bucked around in the sky until the second one finally quit. There were full-size, man-carrying helicopters that used small jets to drive the rotors. This JETicopter might well have been inspired by Marquardt's Whirlijet full-size craft. That $3.75 price in 1952 is the equivalent of $35.60 in 2018 dollars (per the BLM Inflation Calculator), which is cheap for a model kit and one engine with fuel pellets!

Check out my vintage Cox Sky Copter model, which used a single top-mounted .020 engine to drive the rotors via counter-torque.
