Knoller B.I

Aviatik was contracted to build thirty-two Knoller B.I aircraft in December 1915 as Series 35. Flight testing beginning in March 1916 showed abysmal flight characteristics and continued testing showed further failures. They were grounded on November 1916 and it was not until August 1917 that they were finally abandoned and scrapped.

Thöne &amp; Fiala ordered fifteen Knoller B.I(Th) Series 35.8 aircraft and had no better luck turning it into a workable aircraft.
