XP70 Instruction Manual
The Exponential function allows two exponential rates to
be programmed and selected with a switch. Exponential
is available on the aileron, elevator and rudder channels.
Changing the exponential value does not affect the
maximum control authority but only affects control
sensitivity. Exponential is normally used to reduce control
sensitivity around neutral while still allowing high control
authority at the extremes of throw. The sensitivity around
center can be tailored using the Exponential function to
precisely adjust control feel.
Exponential rates can be controlled by their respective rate
switches (aileron, elevator and rudder), or combined on a
single switch, see D/R Switch Select Page .
Exponential is available for the aileron, elevator and rudder
channels. Expo values are adjustable from –100% - LIN
- +100%. The factory default settings for both the 0 and 1
switch positions are LIN or 0%. Either switch position may
be selected to give any desirable EXPO rate by placing
the switch in the desired position and adjusting the value
accordingly.
NOTE
: A negative (-) Expo value will increase sensitivity
around neutral, and a positive (+) Expo value will decrease
sensitivity around neutral.
