Tail Unit
- Cruciform type with cantilever tailplane and upper and lower fins and rudders.
- All-metal stressed-skin construction.
- Leading-edges of fins are wooden and house radio aerials.
- De-icing on tailplane leading-edges.
- Rudders and elevators are both aerodynamically and mass-balanced.
Landing Gear
- Retractable tricycle type.
- Main wheels retract inwardly into the underside of the wings.
- Nose wheel retracts backwards and turns through 45° to lie at this angle under the pilot’s seat.
- Hydraulic retraction.
Power Plant
- Two Daimler-Benz DB 603 E twelve-cylinder inverted Vee liquid-cooled engines.
- One engine in the nose driving a tractor airscrew.
- One engine in the fuselage amidships driving a pusher propeller through a long hollow shaft.

- Annular nose radiator for the front engine and ventral scoop radiator for the rear engine.
- Fuel tanks in A-0 and A-1 entirely in wings with a total capacity of 407 Imp. gallons.
- Fuel tanks in A-6 are in wings and fuselage between two cockpits with a total capacity of 510 Imp. gallons.
- M 50 tanks (33 Imp. gallons) in wings.
Accommodation
- Pilot’s cockpit over the leading-edge of the wing.
- In the two-seat version, the second cockpit is behind and slightly above the pilot for better forward vision.
- Jettisonable cockpit canopy and pilot-ejecting seat.
- Bullet-proof windscreen and armor protection.
Armament
