It's not an uncommon design for modern VTOL UAVs that can transition into single motor forward flight on wings. The twin boom design supports a quadcopter lift system. This is a Chinese airframe manufacturer, people add their own motors and electronics.

Thanks, yes, a couple of those look about right in terms of design and scale. Pretty sure it was military rather than private though.
