Following the departure of Frederick Rentschler and colleagues to form Pratt & Whitney, Charles Lawrance, who formerly headed his own company, became president of Wright Aeronautical, and reacted vigorously with a competitor to Pratt & Whitney’s Hornet. An enlarged and improved Wright Cyclone engine, known as the Model R-1750, made its formal appearance and passed a 50-hour service test during 1927, succeeding the Cyclone P-2, and certificated in January 1929. This model was relatively short lived, and was replaced by the more heavily produced R-1820 beginning in 1930.
Aircraft powered by R-1750, GR-1750, G1R-1750, and R-1750E engines included the: Keystone XLB-6, LB-6, LB-9, LB-10, LB-11, LB-11A, B-5A; Thomas-Morse XO-21A; Douglas O-29; General Avia C-14 and C-15.
