Quoting from the Halberstadt Fighters Datafile:
The Halberstadt fighter was universally esteemed for its facile flight characteristics, quickness of control response and excellent performance, praise probably not equalled until the arrival of the Fokker DVII....Indeed, during a meeting of fighter pilots in Cambrai on December 22 1916 to discuss the future of fighter development, most of the participants opted strongly for the Halberstadt DV powered by a 120hp Mercedes and armed with two machine guns. The reason given was that the Halberstadt was a 'delight to fly'....Frankl flew the Halberstadt in the wildest banks and loops that I had ever seen...The machine was extraordinarily easy to fly, was very fast and stable, and possessed no vices...The wings, unusual for a fighter in that they were of a two-bay configuration, were robust but at the expense of drag-producing struts and wires.
