The top speed is 270 km/h, the range is up to 750 km, and the service ceiling is up to 7,500 meters.

Standardized armament for all variants includes 2 x 7.7 mm (.303") machine guns, fired synchronously via rotating propeller blades. Also envisaged is the installation of a pair of additional guns, one on each side of the hull, z impressive The offensive "one punch".
