CubCrafters Carbon Cub EX

The CubCrafters Carbon Cub EX (EX - Experimental) is an American amateur-built aircraft, designed and produced by Cub Crafters of Yakima, Washington. The aircraft is supplied as a kit for amateur construction.

Design and development
The Carbon Cub EX features a strut-braced high-wing, a two-seats-in-tandem enclosed cockpit that is 24 in wide and accessed via a door, fixed conventional landing gear and a single engine in tractor configuration. The design is related to the company's CubCrafters Carbon Cub SS light-sport aircraft, but adapted to the US experimental amateur-built category.

The aircraft's airframe is made from welded steel tubing, aluminum and the judicious use of carbon fiber, covered in doped aircraft fabric. Its 34.2 ft span wing has an area of 179 sqft and mounts flaps. The aircraft's recommended engine power is 100 to 180 hp and standard engines used include the 100 hp Continental O-200, the 180 hp Lycoming O-360 and the 180 hp ECi CC340 four-stroke powerplant. Construction time from the supplied kit ranges from 700 to 1100 hours (Depending on builder experience).

In August 2022, a new engine option was introduced, the 186 hp CC363i F/P, equipped with a constant-speed propeller.

Operational history
By December 2016 four examples had been registered in the United States with the Federal Aviation Administration and six with Transport Canada.
