08/31/2014. Remarks by Johan Visschedijk: "This high performance aircraft for amateur construction (in kit form) was announced and introduced in 1999 by Team Rocket, Inc. It was a two-seater for engines in the 250-300 hp range and borrowed features of the Harmon Rocket II and Van's RV-4, but it had many differences. The Team Rocket had shorter wings, a sliding cockpit canopy, a wider and re-contoured cockpit/fuselage section, thicker metal sheeting, larger fuel tanks, longer undercarriage units, a more powerful engine, while the tail, although based on the Van's RV-8, was designed by Team Rocket. Unlike the Harmon Rocket II, which used RV-4 components, the Rocket F-1 kit was built from scratch and it was developed under leadership or Mark Frederick.
The Rocket F-1 was the initial version and aircraft were usually built with a Lycoming O-540 series engine in the 250-300 hp range. The first aircraft built from a kit (N121JC) was flown in November 2000 and was built by Jim Cash with a 300 hp Lycoming IO-540-C4B5 engine. The F-1 had wings with constant chord planform. The Rocket F-1 QB was the 'quick build' kit model of the baseline F-1 and it was being marketed from 2001, with the manufacture of parts and components taking place in the Czech Republic. The F-1 QB model also could accept an engine in the 250-300 hp range (usually the Lycoming O-540 series).
Another variant was the Rocket F-1 Evo (for Evolutionary) of which the prototype was first flown on December 18, 2003. This featured an entirely new design wing with modified profile, a tapered planform and increased wingspan. This Evo wing was developed in co-operation with High Performance Aircraft International (HPAI) and the F-1 Evo variant had a better overall performance. By mid-2006 at least five F-1 Evo's had been completed and flown.
Of the more than eighty examples of the Rocket F-1 series flown by today, most were completed in USA, but some were also built in other countries such as Australia, Canada, Italy. N39EJ was built by John N. Andersen of Kenosha, Wisconsin, USA and completed in 2006. Powered by a Lycoming IO-540-D4A5 engine, the aircraft received its CofA on November 9, 2006."
