copying someone elses settings probably wont fix your problems, and it certainly wont help you understand what is going wrong. its critical to set up the deadbands on the logitech before anything else, and it will require plenty. almost all the problems people have with logitechs are down to the spiking pots and slack around the centre, which can be eliminated completely by setting the correct deadband.
do one axis at a time, use the advanced settings, centre the stick and just jiggle it gently. you need to gradually increase the deadband until you dont see any spikes at all. then fly it around for a few sorties to check the difference. after you've done the deadband you can start playing with the damping and scaling if you want, but you dont have to.
