Dan Johnson, reporting on his web site, said that on seeing this lovely display item at the E-Flight Expo at Aero 2015, he “was tempted to pass by as merely a concept that might go nowhere.”  His talk with the designer, airline pilot David De Ridder, convinced him that this project has funding and substance behind it. Don’t send a deposit check just yet.  De Ridder told Johnson that the development of the aircraft should be finished by 2017 and kits should be available by 2019.  In the meantime, the project’s web site provides a tantalizing vision of what could be in electric light sport aircraft.

Randall sold a kit last year for his ElectraFlyer X to Richard Steeves, a physician from Madison, Wisconsin (look for an upcoming entry). and has been providing technical and material support. The X  should take to the skies soon. ElectraFlyer’s Ultralight development took …
