Design

The Wright Model R was derived from the Wright Model B, and was a two-bay biplane with rear-mounted twin rudders mounted in front of a single elevator and carried on wire-braced wood booms behind the wing. It was powered by a 30 hp (22 kW) Wright four-cylinder inline water-cooled engine driving a pair of pusher propellers via chains.[1]

Operational history
The "Baby Grand" at Simms Station, Ohio.

Two examples were flown at the International Aviation Tournament at Belmont Park in November 1910, one being a standard model flown by Alec Ogilvie and the other being a special competition model known as the Baby Grand, which had a 60 hp (45 kW) V-8 engine and a reduced wingspan of 21 ft 5 in (6.53 m). Orville Wright succeeded in flying the Baby Grand at a speed of nearly 70 mph (110 km/h). Both aircraft were entered for the second Gordon Bennett Trophy competition which was held at the meeting, but the Baby Grand, flown by Walter Brookins, suffered an engine failure during a trial flight on the race day and crashed heavily. Ogilvie's aircraft also had engine problems, having to make a stop of nearly an hour to make repairs, but was nevertheless placed third.[2]

Ogilvie also flew his aircraft in the 1912 Gordon Bennet competition, re-engined with a 50 hp (37 kW) N.E.C. engine.
