Evangel Aircraft 4500 STOL
The Evangel Aircraft Corporation was established to design and build a bush aircraft particularly for use by missionary groups. For work in South America it had to have STOL capability and be simple to operate and maintain. The aircraft that was designed was designated the Evangel 4500-300 and was a twin-engined monoplane.
By 1963, Carl Mortenson had created a high wing strut-braced, twin engine plane with a fabric over metal tubing fuselage and a metal wing. At that time it was a fixed gear tricycle design.
The prototype Evangel 4500-300 first flew in June 1964 and the first production aircraft in January 1969. The aircraft needs a very short take-off run and can achieve a take-off to 50 ft (15m) within 375yds (343m).
With a planned first production run of 12, only a total of 8 were built (a 9th was never completed). The unit cost was US$70,500 in 1971 but manufacture ceased in 1974 after seven production aircraft were built.
