RE: How much expo do you pattern pros use? If any
I personally have to agree with Mike above. This is a feel thing. I don't fly with any. I have played with it, and didn't like it, but I fly with VERY stiff stick springs instead. Mike's setup above is probably best. Set the throws for how you need the plane to fly depending on your class and dial in expo to get the "feel" you want. I think the switches and such you flip during flight for rates are just distractions, but in some cases it is necessary, but less is definitely better. So find some rates that allow you to get through the sequence you are flying comfortably and dial in expo to get the feeling of how you want the plane to fly. Set your rates to what you need...as Mike said, don't set 25 when you use 12. One thing with lots of expo is that it can make wind corrections more difficult, if you setup is too soft around neutral as the plane might get bounced around on a windy turbulent day, you will find yourself having to move the stick fairly far to compensate and can actually end up chasing the plane. I think if you get more than 30-40% you will start having problems with this.
