CubCrafters has officially introduced the Carbon Cub ULT, the first U.S.-manufactured turboprop aircraft eligible for Sport Pilot operation under the FAA’s new MOSAIC regulations, powered by TurboTech’s TP-R90 regenerative turboprop engine. The aircraft, based on the Carbon Cub UL platform, features a FADEC-controlled engine delivering turbine smoothness with piston-like fuel economy—observed at 6–10 gph in flight and estimated at 4–5 gph at 50% power—while running on Jet-A or diesel. With an empty weight of ~880 lbs, max gross of 1,865 lbs, and a 682-mile range, the ULT offers a 985-lb useful load and 130+ mph cruise. Base price is $690,000; dealer deliveries begin first half of 2027, consumer deliveries second half. Initial units will be licensed experimental/amateur-built, with flight testing ongoing near Yakima, Washington.
