DUAL RATES AND EXPONENTIAL
Dual rates are available for the aileron,
elevator and rudder channels of your
R/C aircraft. The combined Dual Rate
Function is discussed on Page 24 -
Switch Select. Dual rates may be defined
as the ability to vary the travel or throw
rate of a servo from a switch. Due to the
differing travel rates, you will find that the
sensitivity of the control either increases
or decreases accordingly. A higher rate, or
travel, yields a higher overall sensitivity.
You may find it easier to think of the Dual-
Rate function as double-rates
Exponential reduces the sensitivity in the
middle portion of stick movement, while
still allowing full travel at the end of the
stick movement. The end result (travel)
remains the same, although exponential
changes the rate at which it achieves
this travel. The adjustable range is from
0–100%. Zero percent (0%) is linear
stick control, meaning the response
rate is equal throughout the stick control.
100% is full exponential. The larger the
exponential value, the less servo action
or sensitivity you will notice around the
or half-rates.

The amount of travel is adjustable from
0–125% in 1% increments. The factory
setting, or default value, for both the
0 and 1 switch positions is 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.
Accessing the Dual–Rate and Exponential Function
1. Place the transmitter power switch in
the On position.
2. Access the Function mode by
pressing the
D o w n
and
Select
keys simultaneously.
3. Press either the
U p
or
D o w n
key until
D/R & EXP
appears in the upper left
corner of the LCD.
4. Press the (+) or (-) key until the
desired channel (aileron, elevator or
rudder) appears.
5. Select the switch position for which
you want to adjust the rate. The number
to the upper right of the current rate
value on the display indicates the
current position of the Dual-Rate switch
for the channel that you have selected.
Either a 0 or a 1 will be shown,
corresponding to the position of the
switch. To select the opposite switch
position, move the appropriate Dual
Rate switch to the opposite position.
The number that appears above the
current rate value reflects the change.
6. Adjust the rate for the channel and the
switch position just selected. To
decrease the throw rate, move the
cursor to the D/R position using the
Select
key, then press the (-) key. To
increase the throw rate, press the (+)
key. As stated previously, the adjustable
rate is from 0–125% for each switch
position and channel.
7. Press the
U p
arrow key to access the
REVERSING SW
menu.
8. Press the
D o w n
arrow key to access
the
SERVO TRAVEL SCREEN
.
9. Press the
D o w n
arrow and
Select
keys simultaneously to exit the
DUAL RATE AND EXPONENTIAL
mode.
