The aircraft features a cable-braced hang glider-style high-wing, weight-shift controls, single-place accommodation in the seated position, foot-launching and landing and a single engine in pusher configuration.
The engine is a lightweight, two-stroke, single cylinder Radne Raket 120 of 14 hp (10 kW).
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.
