Thanks, tonytales. Fascinating to read that the Connie had PFCUs on all primary flight controls, whereas the Boeing B367-80 jet transport, launched as late as 1952 and first flown in 1954, relied on balance-panel assistance for elevators and ailerons, although roll control was supplemented by the hydraulically-powered spoilers. (Perhaps you or someone else can tell us whether the rudder-boost system familiar to B707 crews was fitted to the Dash 80 at launch, or if it was a retro-fit.)
Did the Connies have any feel system, and if so was it Q-feel?
