Engine BMW 801 D 2/25453.
Tight engine cowl.
Split flaps with reinforced actuator.
Armament: 2 MG 17, MG 2 151.
MG FF - hatches.
Armored ring mounting bracket as per BSK 190.6.941.
Rudder bellcrank as per KBV 25326.
(20° - rudder deflection).


1. Assessment of the rudder forces with the bell crank installed for 20° rudder deflection instead of the 1:1.8 differential.
2. Check of flight characteristics with direct mounting of 250 kg bombs under each wing.
3. Endurance testing of the armored ring mounting bracket.


1. The flight results with the rudder bell crank for 20° rudder deflection are good in contrast to the lever for 25° rudder angle. Regarding forces, no substantial difference relative to the differential can be noticed, so that as a start, replacements can be carried out on the A-tail without further notice. However, steep slipping must be dispensed with, since rudder deflection is insufficient for this.
The possible use of the bell crank for the D - tail is still under consideration.
2. To test the flight characteristics with direct mounting of the 250 kg bombs under the wings, wood bombs were used. These were bolted to the wing and could not be jettisoned, so that the landings could only be performed with the landing flaps in the take-off position. Already shortly after take-off, disturbance was evident in the control stick upwards from around Va = 250 km/h, caused by buffeting of the ailerons. Increasing speed increased disturbance. Thus, operation of the machine in this condition is not possible. Whether an improvement could be achieved by lowering the bombs without fairing, still needs to be investigated, if required.
3. Flight time to date with the armored ring mounting as per BSK 941 is 18 hours. No faults were noted.
