Totti, OK,I`ll` add a couple of other bits as your calculator is warmed up;
IF the helo now enters a full autorotation,how much aft stick movement is produced at a variety of airspeeds,to keep a level attitude;
now do it all at a fwd C o G...
now consider the fact that the aircraft has yawed(depending on airspeed and fin size)which may also have a `pitch` effect..
now consider where the stick/disc relationship is to tail- boom.....and your stick margins vs control stops
Answers on a postcard,,,...or sheets of A4.....
