Design and development
[Vous devez être inscrit et connecté pour voir ce lien] formed the Spencer-Larsen Aircraft Corporation and designed the SL-12C amphibian.
Disenfranchised with corporate policies in the development of the SL-12C amphibian, Spencer started the Spencer Amphibian Air Car in 1940.
The original Spencer Amphibian Air Car was test flown in 1941.
The aircraft was put into storage due to restrictions in place in America during WWII.
The aircraft and rights to its design were sold to Republic as the "Seebee" in 1943.

After leaving Republic, he designed the on-off two-seat Air Car.
In 1968 Spencer and retired USAF Col. Dale L. "Andy" Anderson formed a new company to market a four place amphibous homebuilt design once again called the Spencer Amphibian Air Car.
With S-12C, S-12D, and S-12E, and S-14 variants.
The first example was test flown in 1970 in [Vous devez être inscrit et connecté pour voir ce lien].
The unit had a build cost of $8700.00 The S-12-D Aircar is an improved and larger four-seat aircraft, which retains the basic layout of the Seabee.
The two seat S-14 used advanced composites and was test flown by Spencer in 1983 at the age of 86.
Its design did not meet expectations and the sole example was donated to the [Vous devez être inscrit et connecté pour voir ce lien] Museum in [Vous devez être inscrit et connecté pour voir ce lien].

The Air Car is built from wood, steel and glass-fibre.
It has a strut-braced high wing and the cabin and fuel-carrying floats are similar to the Seabee, but the tail unit is more angular and a retractable tricycle undercarriage is fitted.
In addition to examples constructed by Spencer, plans of the design have been sold for home construction and the first [Vous devez être inscrit et connecté pour voir ce lien] Air Car flew in September 1974.
Over 50 had flown by 2001.
Examples are currently (2009) flying in the USA and Canada.
