Idle-Up-
A switch on the controller actuates a special function, known as "idle-up." Idle-up
offers an alternate throttle and pitch curve, different from the curves used for hovering.
Idle-up is usually used for aerobatics, when the pilot wants engine power added when
pitch is subtracted. For example, inverted hovering requires positive throttle and
negative pitch. As such, pulling the collective stick back provides positive throttle
AND negative pitch simultaneously.
