Looks like three lights attached to a delta kite?
I've been flying stunt and power kites for close to 14 yrs and if that isn't a delta stunter I'll be shocked.
Since it seems to pivot on the wing tip, and not on the axis, I'm guessing a dual line and not a quad. Plus, quad deltas usually have a more swept (out, not back) flying wing design than that displays.
This was my very first stunt kite, a dual line, ripstop nylon on fiberglass spars, 'Ultrawing' delta.
I've moved up a few times since to this 15m2 (27Ft x 6.5Ft) quad line , twinskin design, depowerable 'Bomba' by NZ kite designer, Peter Lynn. Think of the UFO that bad boy could make. LOL
