Overview
- CubCrafters announced the Carbon Cub ULT on Tuesday, July 7, and said the airplane is finishing flight testing before a public debut at EAA AirVenture later this month.
- The ULT replaces the Rotax piston with TurboTech’s TP‑R90 regenerative turboprop and uses full FADEC, a single‑lever power control and a dedicated turbine display to simplify engine management.
- CubCrafters says the ULT is the first U.S.‑manufactured turboprop eligible for sport‑pilot operation under the FAA’s MOSAIC rules, a claim the company is using to position the model for broader pilot access.
- The company is taking production deposits, expects initial customer deliveries in 2027, and plans to show the airplane at its AirVenture booths in Oshkosh.
- The turbine runs on jet‑A and is billed as having fuel burn closer to piston engines thanks to a regenerative cycle, a feature that could ease avgas reliance and change refueling options for backcountry flyers.
