The company's new WATTsUP, a two-seat airplane design targeted for flight training, took flight last week, and Pipistrel hopes to deliver it to customers as soon as next year. The Siemens AG motor that powers WATTsUP weighs just over 30 pounds and produces 85kW. Pipistrel claims the motor produces more power than a Rotax 912 and can be fully charged in about one hour thanks to the company's battery management technology. The airplane is expected to be capable of flying for about one hour with a 30-minute reserve and it is most efficient in the pattern where as much as 13 percent of the energy is recuperated during each approach, Pipistrel said.
