Daimler L 11
   Built to the parasol formula, the L 11 was remarkable in having ailerons that were balanced by independent surfaces which overhung the tips, but at the leading edge, thereby imparting a back-to-front appearance to the wing. Actually these overhung surfaces were more accurately servos. Engine, 185 h.p. Daimler D IIIb.


Daimler L 14
   Although designed towards the end of the war, the L 14 was not completed until after the Armistice. It is reputed to have attained 190 km.hr. (118.75 m.p.h.) on test, and climbed 5,000 m. (16,400 ft.) in 25 min. with the 185 h.p. Daimler D IIIb engine installed.

DAIMLER L 11 Germany

   The L11 single-seat parasol monoplane fighter was the first aircraft built from the outset by Daimler's Flugzeug Abteilung to the designs of Hanns Klemm. Of exceptionally clean aerodynamic form, powered by a 185 hp D IIIb eight-cylinder water-cooled engine, and featuring swivelling wingtips which served as servos and balanced the ailerons, the L 11 was flown for the first time on 8 November 1918. During trials in the following February, it attained an altitude of 19,685 ft (6 000 m) in 17 min and achieved an absolute ceiling of 27,560 ft (8 400 m). Only one prototype of the L 11 fighter was completed.

Max speed, 124 mph (200 km/h).
Time to 3,280 ft (1000 m), 3.2 min.
Span, 39 ft 4 1/2 in (12,00 m).
Length, 26 ft 8 9/10 in (8.15 m).
Wing area, 310 sqft (28,80 m2).


DAIMLER L 14 Germany

   Owing much to Hanns Klemm's single-seat L11, but embodying further aerodynamic refinement and featuring an exceptionally clean oval-section semi-monocoque fuselage, the L 14 tandem two-seat parasol monoplane fighter retained the 185 hp Daimler D IIIb eight-cylinder water-cooled engine and swivelling wingtips of the preceding fighter. Intended armament comprised a single forward-firing 7,92-mm LMG 08/15 machine gun and one Parabellum of similar calibre in the rear cockpit. The sole prototype of the L14 was completed in the autumn of 1919, and, together with the L 8, was offered for sale to the Chilean government, a mail-carrying version being proposed as the L14V. In the event, no further example was completed.

Max speed, 128 mph (206 km/h).
Range, 435 mis (700 km).
Time to 3,280 ft (1 000 m), 3.1 min.
Empty weight, 1,918 lb (870 kg).
Loaded weight, 2,800 lb (1270 kg).
Span, 40 ft 4 1/5 in (12,30 m).
Wing area, 322.93 sq ft (30,00 m2).

Daimler L 11
  
   Daimler's final single-seat fighter, the L11, was a parasol monoplane that apparently first flew on October 1, 1918. It would have been designated the Daimler D.III had it been accepted by Idflieg, but was too late for that. Like the other Daimler fighters, the L11 used the 185 hp Mercedes D.IIIb V-8 engine. The L11 proved to have exceptional performance, with a top speed of 240 km/h and a climb to 5,000 meters in 13 minutes. The L11 was delivered with unbalanced ailerons and was then modified with vane-balanced ailerons that received a patent in 1919.


Daimler L.14

   The Daimler L 14, designed by Klemm, was a slightly larger, two-seat fighter derived from the L11 fighter. First flown by von Thuna in the fall of 1919, had it been tested by Idflieg it would have probably been designated the CL.II. It was the final Daimler design. It was offered to Chile without result. Unfortunately, no performance data is available.
