Although the Sportavia RF4D had been around since 1966, it wasn’t too widely known until May 1969 when Mira Slovak flew one across the Atlantic to win the 1,000£ prize offered by the London Evening News for the best performance by a light aircraft under 5,000 pounds in the Daily Mail Air Race. Using a converted engine, the RF4D was preceded by models RF-01, RF-2, and RF-3 during the years 1960 through 1966. The all-wood single-seater is rated fully aerobatically and combines the characteristics of a sailplane and a small powered sportplane. A single main landing wheel retracts forward manually into a fiberglass cowling. The small tailwheel is steerable, and there is a manually operated brake on the main wheel.
