EC did some interesting FBW work on a Dauphin whilst developing the successful NH90 FBW system,including fitting an adjustable elevator and a rudder to offload the main rotor during takeoff/climb. The aircraft flew a series of flights with a safety pilot in the l/h seat with conventional rod controls bur the conclusions were vague.this Dauphin can be seen in the Helicopter Museum whilst the NH90 can be seen in Afghanistan, Australia, France, Germany, Greece, Italy,Netherlands , Spain et al!
