WKF 80.07

  Concurrent with the 80.06 fighter, the WKF engineering department designed a two-seat version known as the WKF 80.07. Equipped with veneer-wings and powered by a 230 hp Hiero engine, the 80.07 was completed in late 1917 - early 1918. Flars reported that the fixed machine gun was installed in February 1918. For unknown reasons the 80.07 does not appear again in the official records until 7 August 1918, when it was reported at Aspern. On 19 September 1918, the 80.07 was flown against four aircraft in competitive trials: the Phonix 20.21 and UFAG 60.03 prototypes and two production Phonix C.I biplanes, 121.72 and 121.82, all powered by the 230 Hiero engine (except the last, which had a "Marcellino-Fiat" engine, possibly a new design or one taken from a captured machine). Of the five two-seaters, the 80.07 demonstrated the best rate of climb that was labelled as being "exceptionally superior." Nothing is known of its subsequent history.
