Daimler G.I

   Daimler's first two-engine bomber design, the G.I, ordered as 476-1915, was not completed and no further information about it is available.


Daimler G.II (480-1915 Tractor)

   The Daimler G.II was designed by Schopper but was a completely different aircraft than the earlier Union G.I and the related Daimler R.I and R.II. The Daimler G.II, aircraft 480-1915, was a two-engine bomber with its 220 hp Mercedes D.IV engines mounted as tractors.
   Daimler test pilot Irrek flew the G.II (tractor) on November 20, 1916, which may have been its first flight. Unfortunately, like the earlier R.I and R.II the G.II 'hung right' (banked to the right) and turned right and the ailerons were ineffective because the upper wing bent under the aerodynamic loads and stretched the aileron control cables. The rudder control was too heavy and the elevators were light. The aircraft was tail heavy and Irrek could not maintain directional control with one engine throttled back to simulate engine failure. Although six aircraft had been ordered, development of the tractor version of the G.II may have been stopped at this point because there is no more information about further tests flights, additional airframes, or technical modifications.

Daimler G.II (Tractor) Specifications
Engines: 2 x 220 hp Mercedes D.IV
Wing: Span Upper 17.0 m
General: Loaded Weight 2,700 kg
  


Daimler G.II (480-1915 Pusher)

   Schopper also designed a pusher version of the Daimler G.II that was very similar to the tractor version but had a larger lower wing, now of equal span with the upper wing. Daimler test pilot Irrek made seven unsuccessful take-off attempts in this aircraft between March 16 and April 19, 1917. On June 28 Irrek was finally able to get the recalcitrant G.II (pusher) into the air, but its flying qualities were very poor. Irrek was barely able to land the aircraft safely after a nerve-wracking flight. To the relief of the pilots, further development of the Daimler G.II was abandoned.

  This was followed by a lighter aircraft (R.II), equipped with 2 x 220 hp Mercedes engines, which again did not show positive flight characteristics.
