Bristol B.R.7

The German version was to be built by Deutsche Bristol-Werke using a 90 hp (70 kW) Daimler engine, so Coandă had to prepare a design suitable for both powerplants.

The first of five B.R.7s ordered for Spain appeared at the Olympia Aero Show in February 1913, flying for the first time in March at Larkhill.

Behind the cockpits, the fuselage was quite slender, carrying a nearly semi-circular tailplane with a one-piece elevator and a finless balanced rudder.

The undercarriage had the unusual four-wheel form used by the monoplane, with a pair of large wheels mounted below the wing trailing edge and aft of the centre of gravity, together with a slightly smaller pair forward of the engine; the B.R.7 sat on the ground like a tricycle undercarriage aircraft.

A final, seventh B.R.7 was fitted with larger-span wings, but the only example to do much flying was the first prototype, which remained in service at Larkhill as an advanced trainer.
