Today this model lives on in Postal contests, local contests and the Nationals that run the event

IMG_4530The model is very small and only has a 18″ wingspan and most today are powered with .15 sized glow engines

The event is flown with 52′ 6″ long solid lines (.014 dia) and is timed from a standing start for 16 laps. The fuel system must be a suction feed system (no pressurized tanks) and Tuned Pipes are not allowed

Engine size is limited to .15 cubic inch glow or diesel, or .19 cubic inch Ignition engine

The model has to be built to match the outline on the original plans including the wheel diameter and spinner, however the engine may be mounted inverted, upright or to the side

IMG_4531Even if you are not a experienced speed flyer you can compete in this event without a high tech engine

There are 4 awards for Perky, 1st, 2nd, 3rd and average speed. At any contests the top three speeds will get an award, but also the average speed is calculated and the person with a speed closest to the average speed also wins an award

With the average speed award you don’t have a high end motor to win an award

There is not much room for the tank - 1 1/4 ounces will be enough
