Development[edit]

The Carbon Cub SS was originally named the "CubCrafters Super Sport Cub".[2] In order to maintain certification under American Light Sport Aircraft limitations the maximum takeoff power is limited to five minutes.

Design[edit]

The Carbon Cub SS uses a carbon fiber spinner and air-induction scoop. The Carbon Cub weighs 250 lbs less than a Piper Super Cub.[3] The carbon cowling weighs six pounds. [4] 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 7 lbs less than an all-color paint job.

The CC340 engine is a Lycoming O-360 based engine developed with Eci using dual electronic ignition and Eci O-320 cylinders.[4] The engine is rated at 5 gallons per hour at the 80 hp cruise setting.
