Dornier DO B 1.
The Dornier DO 217 B 1.
One of the most novel features of the DO 217’s design was the dive brake which was attached to the extreme rear fuselage. The brake operated somewhat after the fashion of a parachute, or a four ribbed umbrella, the ribs closed forming the four sides of the tail extension. Despite the external similarity to the DO 17, the 217 did not emulate the good natured characteristics of its predecessor. There was a marked tendency to swing during take-off, directionally stability was not very good & control response was sluggish.

Dornier DO217 V4.
Early in 1939, a third Jumo engined prototype, the Do 217 V4 joined the test programme. This being intended as the production prototype & the first aircraft of the series to carry armament. The V4 also had a dorsal strake in an attempt to rectify a stability problem. In general Test Pilots reports were unfavourable, stability being poor, & performance falling short of requirements.
