here's another Not an e-glider but a fossil burning, screaming jet engine, glider looking but short winged--

That was an early concept for a personal jet airplane modelled on a glider type fuselage with a wing designed for the flight characteristics envisioned. It was to use a PBS TJ-100 engine like the one Bob was using on his airshow Salto glider (www.vertigoairshows.com) and the two-seat retractable engine TsT-14 BonusJet glider (as well as the four jet powered Arcuses built by Desert Aerospace.)

The design was superseded by the jet powered SubSonex from Sonex Aircraft. About a dozen or more are flying today, with probably 20 more kits in progress. https://en.wikipedia.org/wiki/Sonex_Aircraft_SubSonex

The XLJ (Extreme Light Jet) concept may be revisited in the future by Desert Aerospace if time permits.
