Back in 1939, a newly designed freeflight model appeared on the contest circuit that was a real performer and set a trend in style and features. It was emulated by many other modelers and became well known on the contest winners list. With its clean aerodynamic design, it surely was a trend setter. The elliptical wings with polyhedral made it instantly recognizable. In the late 1930s, the newly developed model engines with "rear-disk rotor intake" breathed new life into the contest performances of the current freeflight models. The increased power that these engines developed required some rethinking of the typical models flown during this period. They would loop or spiral into the ground easily. The Skyrocket was the culmination of the evolution made during this transitional period. A longer tail moment plus a high line of thrust and low center of lateral area were the hallmarks of this design. The Skyrocket was built in several sizes and the Class A (.19 ci displacement) size won in the 1939 Nationals in Detroit, Michigan, and most contests at the Creedmore, Long Island flying sites.
