    P-39 Airacobra 
    WWII Whip Powered Control Line Model 
    Designed By Frank Macy

    The P-39 Airacobra was designed by the Bell aircraft company and features several innovative features including a mid mounted engine that was located behind the pilot and a cannon that fired through the prop hub.   Because the prop shaft passed under the cockpit, the pilot was in very cramped quarters.   Consequently, only shorter pilots found themselves flying this bird.   Although the Airacobra flew with the U.S. Army Air Corps, it is best known as the export fighter used successfully by the Russians against the Germans during their ill-fated invasion of the Soviet Union.   The Junior Ace model of this famous aircarft captures the Airacobra's sleek lines well.   This easy-to-build model will have you flying "tank busting" missions in no time at all!

    "Whip Powered Control Line" models are 1/2A size profile control line models that do not use an engine for power.   From the control handle, the control lines pass through the eyes of a 6 foot fishing rod through the line guide on the wing, and to the bellcrank.   As the flyer turns with the rod, the model is pulled through the air.   The speed and duration of the flight are controlled by the pilot.   Line length is 15' to 30'.   This is a good way to get started in control line and to learn stunts.   Whip Powered Control Line was started in 1943 by "Jim" Walker.   Because of the war, engines and fuel were very hard to get.   The whip powered system solved these problems to some extent.   Today this method of flying allows flight anywhere as there is no noise and little risk of injury.   These planes can even be flown indoors which makes flying a year 'round hobby! 

    The availability of these great whip powered models is, to a great extent, due to the efforts of Frank Macy.   Frank grew up in Portland, Oregon where he met the legendary Jim Walker as he was demonstrating his airplanes at parks and schools around the area.   Jim became his boyhood hero and Frank was certain he wanted to work for him.   This was not to be, as Jim Walker died in early 1958.   A few years later Frank decided to preserve the history of the American Junior Aircraft Company and the legacy of Jim Walker.   In the 1980's Frank released Whip Powered Control Line kits designed by "Jim" Walker and sold by American Junior. They were so successful that he designed and kited other models.   This effort continues today with American Junior Classics.   Today Frank Macy is a design consultant for Black Hawk Models while running American Junior Classics and producing a line of American Junior products
