, single cylinder Radne Raket 120 of . The Doodle Bug differs from other powered hang gliders in that the pilot flies in the seated position. A cloth fairing behind the pilot streamlines drag and provides space for baggage stowage. The propeller is protected on the ground by two support legs that retract automatically when the pilot assumes the normal flying position, though pressure on the foot rest. Electric starting is optional.
