The HS.42 was not a derivative of the Fokker D-XXI as has been claimed in some publications. Its only similarity was a set of landing gear (although these were also modified). The design of the HS.42 was the work of Emilio Viejo, Fulgencio Amador and Marcelino Viejo. | The HS.42 was not a derivative of the Fokker D-XXI as has been claimed in some publications.

Due to the shortage of engines, the first series of HS-42s were initially equipped with Piaggio P-VIIC.16 engines removed from the Caproni Ca.310 Libeccio that survived the Civil War, but later they were equipped with the more reliable British Cheetah XXV and XXVII engines. | ||
Several experienced test pilots considered it a good aircraft, but the HS.42 was accused of a dangerous tendency to turn the right wing up when stalling, which was serious in a training aircraft. Solutions were tried, such as boundary layer flaps (like those of the MIG-15), but they were not incorporated into production. Of the 29 fatal accidents involving this aircraft dedicated to teaching, it should be noted that 7 aircraft crashed due to collisions in flight or with objects on the ground, 1 was due to failure to release the brakes, and in 8 others it was concluded that the primary cause was engine failure. In any case, several cases of stalling that ended in a flat spin were also confirmed. | Several experienced test pilots considered it a good aircraft, but the HS.42 was accused of a dangerous tendency to turn the right wing up when stalling, which was serious in a training aircraft.

Despite the fact that it served in significant numbers, this aircraft has always been largely unknown, even among Spanish aviation enthusiasts, so it will be fun to be able to fly it in FlightGear! | Despite the fact that it served in significant numbers, this aircraft has always been largely unknown, even among Spanish aviation enthusiasts, so it will be fun to be able to fly it in FlightGear! | ||
