halas,
Q pot. Q is the aero abbreviation for dynamic pressure which is used to adjust control feel. The rudder ‘fir tree’ wasn’t directly associated with feel, more rudder / fin strength, but still speed related. It was rumoured that the Q pot design (and build) was the same as used in the Comet.
‘Tri Wing’ screws; new at the time, cheaper, stronger than cross head, lighter than slotted head.
300 series tailstrike - flight test (ground test) of minimum unstick speed during take off it was ‘discovered’ that the tail bumper was in the wrong place. Something to do with centre of rotation on the ground and compressed oleos. Cheaper to add rubbing strip than reposition tail bumper, which was removed. Also taken off other series as a wt / drag reduction ?
Love or hate; it was fun.
