Fmode,ID1 or Stunt are used when you want to start sport flying. Loops rolls inverted etc. So you have to set the pitch curve linear 0,25,50,75,100 to give you -11º,0º,+11º pitch and you will need a constant throttle so as when you flip inverted, low stick doesn't reduce throttle so for example. 100,95,90,95,100. The dip to 90 is used to reduce throttle at centre stick 0º pitch to reduce RPM as there is no resistance. But personally i just stick at 100% across the board.
Hope this makes sense.
