- Two tandem open cockpits, the passenger in front of the wing and the pilot behind it
- Fixed slats along the outer half of each wing leading edge, and a fixed tailskid undercarriage
A small open-cockpit parasol monoplane. The passenger sits ahead of the wing and the pilot behind it. It is not a biplane fighter.
