https://en.wikipedia.org/wiki/Curtiss_R3C

The Curtiss R3C was an American racing aircraft built in landplane and
floatplane form. It was a single-seat biplane built by the Curtiss Aeroplane and
Motor Company.

The R3C-1 was the landplane version and Cyrus Bettis won the Pulitzer Trophy
Race in one on 12 October 1925 with a speed of 248.9 mph (406.5 km/h).

The R3C-2 was a twin float seaplane built for the Schneider Trophy race. In
1925, it took place at Chesapeake Bay in Baltimore, Maryland. With 232.57 mph
(374.274 km/h), pilot Jimmy Doolittle won the trophy with a Curtiss R3C-2. The
other two R3C-2s, piloted by George Cuddihy and Ralph Oftsie, did not reach the
finish line. The next day, with the same plane on a straight course, Doolittle
reached 245.7 mph (395.4 km/h), a new world record. For the next Schneider
Trophy, which took place on 13 November 1926, the R3C-2's engine was further
improved, and pilot Christian Franck Schilt took second place with 231.364 mph
(372.34 km/h).
