The aircraft features a
cable-braced hang glider
Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame cover ...

In aviation, the term tractor configuration refers to an aircraft constructed in the standard configuration with its engine mounted with the propeller in front of it so that the aircraft is "pulled" through the air. Oppositely, the pusher co ...

, single cylinder NAGL. The engine is mounted beneath the glider's keel tube, with the exhaust system facing forward and driving a large propeller via an extension shaft. The large diameter propeller makes for quiet operations, including on takeoff. The fuel tank capacity is , with optional.
The preferred launch and landing position is prone, with the pilot relying on wheels on the control bar and a short trolley with wheels supporting the pilot's feet and pod. Foot launching is also possible.
In reviewing the aircraft, Rene Coulon noted that the NAGL is "a very original design".
