The three seater Genaircos were expected to find a market with the many Australian aviators of the era who were making a living out of joyrides and barnstorming tours, who could double their payload for each flight at a minimal increase in operating cost.

With a little ingenuity, a tight squeeze and children on laps, gypsy joyriders often enticed even more paying passengers for a flight in a Genairco's wide front cockpit.

The fuselage, however, was wider than that of the Moth, allowing two passengers to be carried seated side-by-side in an open cockpit ahead of the pilot's.

A 10th Genairco was built as Cabin Floatplane by Tugan Aircraft who took over the GAC premises when that business collapsed during the Depression.

All but three were built with ADC Cirrus Hermes upright engines, the seventh example was fitted with the locally designed 4 water cooled upright 4 cylinder inline, the Harkness Hornet, but while its performance was satisfactory, the extra weight of the engine and its radiator offered no benefit over the air cooled ADC Cirrus.
