Well, I don't jam the sticks around and still find that 60-70% expo is good for me. Raiderron above says he flys with 70% and I have heard others talk about that much or even a little more -- I think really that it is setting it up for how you personally like the aircraft to "feel". My baby low rates with that much expo do a fine job on the plane -- the surfaces are rather large so a little movement still works -- Maybe some others on here will chime in -- I would hate to be responsible for your maiden flight and me with not much experience with this type of aircraft.
