It has a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem, open cockpit, tricycle landing gear and a single engine in pusher configuration.

The uncrewed aircraft was tracked by radar as it flew out to sea north of Newcastle, after which it presumably crashed into the ocean.
