Carl Mortenson was a pilot and aircraft mechanic who flew in the 1950/60s for the mission aviation organization (JAARS) in South America.

During that time, Mortenson noticed the need of an affordable and capable STOL twin-engined aircraft for such endeavours. So without thinking twice he took the bull by the horns.

He founded the Evangel Aircraft Corporation and undertook the first flight of the first prototype in 1964. Equipped with a high strut braced wing and a fixed tricycle undercarriage, the sole prototype seems to have left something to be desired. The production model became a low-wing, tailwheel retractable undercarriage design. Only 8 of those were produced.

He went on later to produce the AAC Angel 44.
