I have a related question.

Most people have somewhere around 60-70% throttle at 0 degrees pitch for their idle up modes. How do you keep the headspeed under control when you are not doing tuff maneuvers? I use 50% throttle at midstick right now and it works well for the aerobatics I do, but if I try to just fly to the other end of field staight and level the head starts screaming. Do you just go back to normal mode right after every maneuver???
