History

Central Aircraft of Yakima and the Lamson Aircraft Company formed the Central-Lamson Corporation in 1953. The first prototype made its maiden flight on 10 December 1953 and was powered by a Pratt & Whitney Wasp Junior radial.

Variants

Two were built. The second, flown on 18 December 1954, had a fully enclosed rear fuselage, fuel tanks moved from the wing roots into the fuselage and a cowled engine.

Where you'll see it

Four more were under construction when the project was stopped late in 1955. The design was bought by Grumman and developed into the Grumman Ag-Cat.
