Text from an advertisement in the September 1944 issue of Flying magazine EVERY HELICOPTER RECORD BROKEN WITH FRANKLIN POWER On March 2, 1944, the Army's latest helicopter, the Sikorsky XR-6, powered by a 245 hp Franklin engine, flew non-stop from Washington, D.C., USA to Patterson Field, Dayton, Ohio, USA. With Col. H.F. Gregory at the controls, this flight unofficially broke every existing helicopter record. A new distance record was established- 387 miles (623 kmh), non-stop. The XR-6 remained in the air 4 hours and 55 minutes- a new endurance record. It flew the Alleghanies at 5,000 ft (1,524 m), carrying pilot and passenger- higher than any helicopter ever before had flown with such a load. Ground speed for the flight averaged approximately 80 mph (129 kmh)- a new record cross-country speed for a helicopter- despite headwinds from 10 to 30 mph (16 to 48 kmh). Thus the XR-6 dramatically proved itself a practical flying machine, definitely out of the purely experimental stage. And thus another string of "firsts" was added to the long series already held by Franklin engines in the realm of power for flight. Aircooled Motors Corporation engineers are even now planning new Franklin "firsts"- new and finer engines for your post-war aircraft. Specify Franklin power.
