Control Line Sport or Stunter
Engines.45 - .60
By WALTER A. MUSCIANO
An engine of .60-cubic-inch displacement must be used for stunting and is also well suited for sport use although engines in the .49 class can be used for sport flying. The rudder should be offset as the plan indicates and the engine should be offset two degrees to pull the model away from the center of the circle. For flying, use only .016" lines from fifty to eighty feet long. Test with the shorter line.
A BRITISH design, the De Havilland 4 was one of the few designs built in the U. S. during World War I Primarily intended for reconnaissance duty, it wasn't long before the D.H. 4 was bombing by day and night and engaging enemy fighters in combat. To say it was a rugged ship would be an understatement. Powered by either Rolls‑Royce, Hispano‑Suiza or the famous Liberty engines, the craft was turned out in great quantity during 1918 and came in a variety of modifications. The first U. S. Air Squadron to fly in sorties over enemy lines used Liberty‑powered De Havillands. This was in France on April 8, 1918.On April 19, 1919, Capt. E. F. White flew from New York to Chicago (738.6 miles) non‑stop in six hours and fifty minutes. Average speed was 106 mph and this flight established a distance record Four D.H. 4's covered 9,329 miles from New York to Nome, Alaska, and return with an average speed of 80 mph. Numerous stops were made. This flight took place during July 17 to 20, 1920.
