CubCrafters Carbon Cub EX explained

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.[1]

Design and development

The Carbon Cub EX features a strut-braced high-wing, a two-seats-in-tandem enclosed cockpit that is 240NaN0 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 34.21NaN1 span wing has an area of 179square feet and mounts flaps. The aircraft's recommended engine power is 100to and standard engines used include the 1000NaN0 Continental O-200, the 1800NaN0 Lycoming O-360 and the 1800NaN0 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 1860NaN0 CC363i F/P, equipped with a constant-speed propeller.[2]

Operational history

By December 2016 four examples had been registered in the United States with the Federal Aviation Administration and six with Transport Canada.[3] [4]
