The Carbon Cub has redefined expectations for backcountry aircraft. It has taken the fundamentally superior design of the Piper Super Cub and reinvented it using 21st Century materials and computer-aided design. Superior engineering results in the Carbon Cub having 50% fewer parts, and weighing more than 300 pounds less, than a similarly equipped Super Cub. It can take off and land in patches that you thought were accessible only to helicopters and hikers, all while being able to take the abuse of backcountry exploration.
PERFORMANCE
All variants of the Carbon Cub exhibit unmatched power to weight ratios. The Carbon Cub has no equal in takeoff and landing performance. On an average day the Carbon Cub will climb out at 2,100 feet per minute at sea level and pass through 10,000 still climbing at a staggering rate.
The power is ideally paired with the airplane's nimble handling and slow speed manners. Carbon Cub FX and EX are further benefitted by our new G-Series flaps and ailerons. The EX-3 and FX-3, with even more power and a constant-speed prop, deliver the highest cruise speed and efficiency available in the Carbon Cub family. The Carbon Cub UL features the 160 HP turbocharged Rotax 916iS with multi-fuel technology (MOGAS & AVGAS).

The turbocharged, 160-horsepower Rotax 916iS engine was operating at 100 percent power and turning 5,826 rpm at 23.2 inches of manifold pressure when the airplane topped out at a pressure altitude of 35,720 feet. Its indicated airspeed was 61 knots (113 knots true airspeed) at the top of the climb.
The Carbon Cub might have gone even higher without the relatively heavy and dr**** 29-inch Alaska Bushwheel main tires, or a cooler temperature. The standard temperature at 37,000 feet is minus 56 degrees Fahrenheit, about 5 degrees colder than the Carbon Cub recorded at its apex.
