To Adjust The Exponential - Spektrum DX7 User Manual

Dual Rate and Exponential (continued)
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 flight mode switch. Exponential is available for the aileron, elevator and rudder channels. Expo values are
adjustable from -100% (full negative expo), LIN (linear), and +100% (full positive expo). 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. Normally a positive value is used to desensitize
control response around neutral.
