In 2025 American manufacturer CubCrafters commenced production of the first microlight version of its popular Carbon Cub, named the Carbon Cub UL. The 160hp two-seater is powered by a Rotax 916iS and will be available in the US as a factory-built Light Sport Aircraft (LSA) and as a ‘factory builder assist’ Experimental Amateur Built (EAB) aircraft.
By using carbon-fibre in its construction, CubCrafters has reduced the empty weight to 390kg which, meeting the LSA maximum all-up weight of 600kg, provides a useful load of 210kg. The company stated that the UL is specifically designed to comply with the new Modernization of Special Airworthiness Certification (MOSAIC) rules, expected to be introduced by the FAA later this year. It also fits into the UK’s 600kg Light Sport Microlight category.
