I've also found a lot of older high hour Jet pilots, well the ones I fly with who are ex 707 and the like NEVER touch the rudder except in the last instant of a crosswind landing. They will also always trim out using the rudder trim and never the aileron trim as well.
Our old 146-100 is exceptionally bent, I suspect the flaps are a degree or so out as it flies straight as a die with the ailerons offset by about 2-3"! Some roll moment going on there. Very few other pilots at my base will ever adjust the aileron trimmer, and I find a full turn will balance it right at cruise speed. We need a quarter turn of rudder trim but this is power related whereas the aileron trim is speed related.
Two of them, like me, apply rudder on crosswind takeoffs, keeping it applied as they rotate and gently feeding it off to allow the a/c to centre.
I suppose as we have the short one, it does lack much stability, and can't be dispatched without the yaw dampers working as well.
Now I'm no test pilot, but most of the experienced guys keep their feet up and out of the way most of the time. What do I know anyway? Perhaps my fiddling is totally unneccessary.
