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 expos 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 and Expo rates can be controlled by their respective dual rate switches (aileron, elevator and rudder) or by
1 common switch (COM AILE, COM ELEV, COM RUDD, FLAP0 or FLAP2). The choices for this are found on the
D/R SWITCH SEL screen in the System Setup Mode for Airplanes.
Dual rate values are adjustable from 0–125%. The factory default settings for both the 0 and 1 switch positions
are 100%. Exponential values are adjustable from -100% to +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.

Adjust the dual rate values for the selected switch position using the INCREASE or DECREASE keys.
The Dual Rate and Expo functions for aileron, elevator and rudder can be combined on a single switch
conveniently allowing high or low rates to be selected via one switch (COM AILE, COM ELEV, COM RUDD,
FLAP0 or FLAP2). The choices for this are found on the
