Hi Mark,
No - I haven't compared, it's just that to my inexpert eye, 0.063" doesn't look much!
Incidentally, if
"It is designed to take full rudder deflection at over 120 knots, stall turns and aggressive side-slips, all of which are likely to load that area more than a flick-roll"
is true, how come it's not cleared for flick rolls? Somebody, somewhere must have decided that there is some deficiency in the design that precludes them??
