Sceptor (aircraft)

Project Sceptor (Scalable Convergent Electric Propulsion Technology and Operations Research) is a test aircraft, to be built to study the use of distributed electric propulsion (DEP). It involves replacing the wings on a twin-engined Italian-built Tecnam P2006T (a conventional four-seater light aircraft) with DEP wings each containing electrically driven propellers. Test flights are planned to commence in 2017.
