Опытный С VIII имел уменьшенные размеры, одностоечную коробку крыльев и двигатель Мерседес D.III (160 л. с).
  Экспериментальный триплан С VIII Dr. с двигателем Мерседес (230 л. с.) развивал скорость до 170 км/ч.

A.E.G. C VIII
  An experimental single-bay two-seater of Oct. 1917. Multi-spar wings "ear"-type radiators and tail surfaces quite unlike previous A.E.G. designs. Engine, 160 h.p. Mercedes D III. Span, 9.5 m. (31 ft. 2 in.). Length, 6.9 m. (22 ft. 7 3/4 in.). Weights: Empty, 800 kg. (1,760 lb.). Loaded, 1,160 kg. (2,552 lb.). Speed, 170 km.hr. (106.25 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 3.8 min.

A.E.G. C VIII Dr
  This triplane version of the C VIII showed no improvement in climb, and speed was reduced to 165 km.hr. (103.12 m.p.h.). It appeared in December 1917 and did not develop beyond an experiment. Engine, 160 h.p. Mercedes D III. Span, Upper 11.2 m. (36 ft. 9 in.); Middle 10.8 m. (35 ft. 5 1/4 in.); Lower, 10.4 m. (35 ft. 1 1/4 in.). Otherwise as C VIII.

AEG C.VIII & C.VIII Triplane

  The AEG C.VIII was an attempt by AEG to improve the C.VII for the light two-seater escort role. Three prototypes were ordered, all powered by the 160 hp Mercedes D.III. Apparently two were completed as biplanes, the first in July 1917, and the third as a triplane. It should be remembered that the summer of 1917 was the height of Idflieg’s triplane craze, which no doubt influenced AEG to complete one C.VIII as a triplane. AEG apparently hoped to achieve high speed by reducing drag to a minimum; the AEG history claims 190 km/h but engineering specifications show a top speed of 170 km/h. If the higher speed were actually achieved the C.VIII might have been ordered into production, but it was not and a reasonable conclusion is the 190 km/h top speed was not reached.
  The C.VIII triplane used the engine, fuselage, and tail of the biplane C.VIII. Completed in October 1917 and flight tested in November, the C.VIII triplane climbed to 5000 meters in 34 minutes, a climb equivalent to the Albatros D.V single-seat fighter. With 80 kg less load it climbed to 5000 meters in 24 minutes. However, it was slower than the biplane C.VIII and flight-testing revealed the C.VIII triplane to have unsatisfactory flying qualities. AEG had proposed a smaller, lighter triplane in November but the disappointing flight-test results of the C.VIII triplane eliminated that idea as well.

One of the first two AEG C.VIII prototypes; the C.VIII was a cleaner, more aerodynamic design than the C.VII.

The third AEG C.VIII prototype was built as a triplane.The climb rate was good but like most triplanes it was slower than the biplane from which it was derived, and it did not handle as well. (The Peter M. Bowers Collection/The Museum of Flight)
