Power was provided by a 75 hp Revmaster 2100 D Turbo (modified Volkswagen 2,100cc motorcar engine) and driving a Maloof two-blade controllable-pitch (two positions, plus feathering) propeller. Fuel capacity was 35 gal (132 l), including that carried in two 9 gal (34 l) wingtip tanks and a 2 gal (7.6 l) gravity-feed tank in the fuselage nose. A retractable tricycle-type landing gear was fitted, with the main wheels remaining semi-exposed to reduce damage in a wheels-up landing.
Two years later, Alvarez and a Mr. Paul registered the pictured second Pollwagen as N1035S on June 16, 1979. Subsequently Alvarez formed Polliwagen Inc. by at Garden Grove, California to market construction plans for amateur builders, together with a wide range of component parts, including prefabricated fuselage, elevator, spars and wing skins, cowlings, landing gear fairings, canopy and ribs, landing gear assemblies, brakes and instrument panel. N1035S was deregistered on November 28,1982.
By 1983, Polliwagen had moved to Murrieta, California and a large number sets of plans were sold, by 2010 at least 37 aircraft had been registered in the USA (although only a few are still current), as well as a number in other countries, including Austria, Canada and Switzerland, where the type is also known as the PW-235 Supernova.
