The Britannia was a good aircraft, unfortunately it was dogged by engine icing problems which delayed entry into service. I flew the Britannia for ten years and never found it boring, tricky at times maybe, but very satisfying. Ground crews sometimes held on to a prop blade after the prop parking brake was released prior to starting to stop it windmilling in the wrong direction if there was a tailwind.
Regarding the servo tabbed controls, both ailerons and the elevators were drooped down until about 80 knots. This system had limitations when rounding out after a steepish approach!
