Function Mode Functions

Dual Rate and Exponential

The Dual Rate and Exponential function allows two control rates to be programmed and selected with a switch.
Dual rates and exponentials are available on the aileron, elevator and rudder channels. Changing the dual rate
value not only affects the maximum control authority but also affects the overall sensitivity of control. A higher
rate yields a higher overall sensitivity. The sensitivity around center can be tailored using the Exponential
function to precisely adjust control feel.
Dual rates can be controlled by their respective dual rate switches (aileron, elevator and rudder). An auto
dual rate function is available that allows to automatic selection of the desired rates via the three-position
flight-mode switch.
Exponential values are adjustable from -100% to +100%. The factory default settings for both the 0 and 1 switch
positions are 100%. Either switch position may be selected as the low or high rate by placing the switch in the
desired position and adjusting the value accordingly.
