The CubCrafters CC11-160 Carbon Cub SS is an ASTM certified light-sport aircraft based on the Piper Cub. It is modernized, with light-weight carbon fiber components and a 180 hp engine.^[2]

In January 2016 the Carbon Cub was named AVweb's "Airplane of the Year" for 2015.^[3]

Development

The Carbon Cub SS was originally named the "CubCrafters Super Sport Cub".^[4] In order to maintain certification under American Light Sport Aircraft limitations the maximum takeoff power is limited to five minutes.

Design

The Carbon Cub SS uses a carbon fiber spinner and air-induction scoop. The Carbon Cub weighs 300 lbs less than a Piper Super Cub.^[5] The carbon cowling weighs six pounds.^[6] The fuselage is welded 4130 tube steel with fabric covering. The wings are fitted with vortex generators for low-speed flight control. Some models use a partial color on silver base coat paint job that weighs 11 lbs less than an all-color paint job.

The CC340 engine is a Lycoming O-320 based engine developed with ECi using dual electronic ignition and ECi O-320 cylinders.^[6] The engine is rated at 5 gallons per hour at the 80 hp cruise setting.

Specifications (Carbon Cub SS)

Data from Flying

General characteristics

• Capacity: 2
• Length: 22.75 ft (6.93 m)
• Wingspan: 34.25 ft (10.44 m)
• Height: 9.25 ft (2.82 m)
• Wing area: 171.9 sq ft (15.97 m²)
• Aspect ratio: 5.2-1
• Airfoil: USA35(B)
• Empty weight: 896 lb (406 kg)
• Gross weight: 1,320 lb (599 kg)
• Fuel capacity: 24 gallons usable in 25 gallon tank
• Powerplant: 1 × CC340 Horizontally opposed piston engine, 180 hp (130 kW) for maximum of 5 minutes, 80 hp continuous.

• Propellers: 2-bladed CATTO composite propeller

Performance

• Maximum speed: 88 kn; 163 km/h (101 mph) Vno, the boundary between green and yellow on the airspeed indicator.
• Stall speed: 27 kn; 50 km/h (31 mph) out of ground effects, without assistance of engine power, with full flaps (35 kn without use of flaps).
• Never exceed speed: 123 kn; 227 km/h (141 mph) Vne, boundary between yellow and red on the airspeed indicator, achievable in powered flight pitched for dive with 1G wing loading in smooth air.
• Range: 391 nmi; 724 km (450 mi) maximum, using 24.0 gal of fuel, with 1.0 gal unusable remaining in tank, with no reserve fuel.
• Ferry range: 652 nmi; 1,207 km (750 mi) with increased fuel capacity of optional extended range fuel tank.
• Service ceiling: 17,999 ft (5,486 m)
• Rate of climb: 2,100 ft/min (11 m/s) using 180 hp, no flaps, below gross weight.
• Wing loading: 7.37 lb/sq ft (36.0 kg/m²)
• Thrust/weight: 7.33 per hp
