I always start at -50%, and the Ele and Ailerons were fine there ( I think I put in -75% for the ailerons on high rate 'cause they are like 60 or 70 degrees!) But the rudder I ended up with -100% (that's on a Futaba, I'm told others work different.) Going from 60% to 100% vastly improved the hover, I think my other planes need lots more rudder input and I'm used to them!
