I did my first Flat Spin about a week and a half ago. It was with a customized SPAD with rediculous control throws and a less than perfect CG. I did it completely on accedent. I took the plane high and chopped the throttle/split the sticks/full up elevator. I expected an ever accelerating nose down downward spiral but saw a near perfect flat spin with a slow decent. Well I perfomed this maneuver 3 times succesfuly and had 2 succesful recoveries So give yourself some room and don't stare at it to long after you get it right.
