The flight performance is very bad, but the armament is very good. Maybe it could be in the BR 2.0- 3.0 range. On the plus wide with the changes to bomber survivability it would be a tough nut to crack.
Was built in a bomber config with 8 7.62 machine guns and 3 20mm cannons and 14.6 tons of bombs. The first flight was August 11th 1933. On the 9th flight, the right tail boom snapped and the plane crashed, killing 15 people
