Expo
Flight phase specific: -100% to +100%
The Expo parameter can be used to assign an exponential characteristic to
a control curve.
o For Expo = 0%, the control works in a linear fashion.
o The effect of negative Expo values is that the control generates
smaller control surface travels around the centre position providing
finer control.
o The effect of positive Expo values is that control surface travels
are increased around the centre position.
o The end-travels remain unchanged when Expo is used. So, full
travel is still available when required.
