Design and development
The Prince was a privately funded project designed by Captain A.G. Forsyth, who had joined the Fairey company in 1931 as their chief engine designer. The company had hoped to obtain Air Ministry orders for the engine but faced opposition, with the ministry favouring Bristol and Rolls-Royce engines instead.
Three prototypes were built in secrecy; with the engines running by 1933, a single Prince was installed and test flown in a Fairey Fox II biplane in 1934, but no orders materialised.[1]
