[1] The two aircraft, named Texas Wildcat and Cactus Kitten, were single-engined, braced, high-wing monoplanes powered by a 427 hp (318 kW) Curtiss C-12 inline piston engine.

The wing, which had a special double camber airfoil section, was high-mounted, and was braced by struts to the mainwheels of the fixed conventional landing gear.

The V-12 engine drove a two-bladed tractor propeller, and was cooled by radiators mounted on the side of the fuselage between the cockpit and the wings.

[2] The Texas Wildcat was briefly tested in the United States before shipment, being fitted with a different wing with a more conventional airfoil for operation out of the confined Curtiss Field.

Thus modified, it was entered into the 1921 Pulitzer Trophy Race, where, flown by Clarence Coombs at an average speed of 170.3 mph (274.1 km/h), it gained second place behind a Curtiss CR piloted by Bert Acosta.
