Yakima, Washington – June 22, 2015: Backcountry aircraft manufacturer CubCrafters has announced a new program designed to engage airplane buyers more intimately with their purchase. Carbon Cub FX Builder Assist immerses new owners in the construction of the aluminum, steel and composite parts that make up the Carbon Cub, allowing the customer to know their aircraft in the way only an aircraft builder can. FX builders’ efforts are rewarded with a new Carbon Cub certified as Experimental-Amateur Built (E-AB), affording operational latitude to the builder/owner which is unavailable for other aircraft certifications, notably: increased payload potential, night and/or IFR operation, builder maintenance and the ability to modify the aircraft.


Carbon Cub FX turns the familiar ‘builder assist’ convention upside down”, says Jim Richmond, Founder and CEO of CubCrafters. “Instead of assisting your assembly of parts from a kit, CubCrafters’ technicians facilitate your fabrication of the parts themselves! Using our modern facilities and equipment, we will guide you through the fabrication process in an astonishingly short time. Then, CubCrafters will use your parts to assemble a factory-perfect Carbon Cub, complete with all the options that you choose!”

This new program satisfies the FAA Major Portion Rule (or “51% rule”): the builder completes more than half of the aircraft construction described in the Amateur-Built Aircraft Fabrication and Assembly Checklist (FAA Advisory Circular 20-27G, Appendix 8). No technical experience is necessary.


“Our factory personnel will guide you through each process to ensure that your parts are in-spec and meet our quality standards,” Richmond continues. “You can create your dream under the supervision of our staff, and we’ll guarantee delivery of a world-class aircraft.”



The Carbon Cub has advanced the legendary Cub architecture into the twenty-first century, combining modern design methods with lightweight materials and a 180-horsepower engine. The Carbon Cub literally redefines expectations of “backcountry aircraft”, and it assures formidable off-airport performance.

Carbon Cub FX is an extension of CubCrafters’ Carbon Cub EX-2 kit, which delivers the same thrilling performance as the ready-to-fly Carbon Cub, but may be certified up to 1,865 lbs. gross weight, allowing a usable load over 900 lbs.


For the Builder Assist program, the Carbon Cub FX is equipped with a CC340 engine (180 HP), Long-Range Fuel Tanks, Extended Baggage, and 3x3 Extended HD Landing Gear as standard. A range of panels, paint schemes and other options are available.
