This new Robinson R44 Cadet for the UND Aerospace - University of North Dakota departs Heli-Expo 2022. UND bought it to replace UND's first R44 Cadet which recently achieved 2,200 flight hours and required a factory overhaul. UND's flight training school operates five R44 Cadets. The cadet is a two-seat version of the four-seat R44 with lower operating costs for the pilot flight training role.
