DUAL RATES AND EXP CURVE SWITCHING
Programming this function
change the function operation rate and operation
curve for any three channels by moving a switch.
You may add switchable exponential response to a
function without using the A F R menu. The switch
position and ON/OFF direction can be chosen, or
you may link ON/OFF control with the position
of a control stick, such as throttle.
If you want to change the response rate around
stick neutral, you can use the EXP1 mode, and
make the servo movement sensitive or insensitive
(0% exponential produces a normal straight-line
response). For positionable controls like throttle,

Activation of command
In the Condition Menu, press the D\R key to get to
the A to C Dual Rate circuit selection screens (not
shown). Choose the desired Dual Rate circuit with theA
to C keys, to get the D/R menu shown below (the 'A'
menu is shown).
Dual Rate Control Selection
To select the control to be used in the Dual Rate func-
tion, press the B key, then press the key of the channel
to be set with the E to L keys. Initially, Circuit A is set
for Aileron. Depending on the Model setup, the following
keys will appear on the bottom of the screen:
Airplane:
Helicopter:
Sailplane:
Activate the Dual Rate
Press the A key to get to the activation keys. Select
the D/R mode by pressing the ACT F key, or deacti-
vate the function by pressing the INH G key.
Setting The Dual Rates
Press the C key, and set the side A rate with the rate
setting keys F to M . Use the numeric key closest to the
value you'd like to set, then press the + and - keys ( F
allows you to

the EXP2 mode may be used to control the rise of
the curve, either steep or gradual as the stick is
moved. A special linear mode uses a particular
value of the EXP1 curve to simulate operation of a
linear servo with an ordinary rotary servo.
Initially, the three separate Dual rate circuits
are set as follows: D/R A: Aileron; D/R B: Eleva-
tor; D/R C: Rudder. Of course you may change
these to control any function.
NOTE: If the throttle curve and pitch curve
functions are activated, the throttle channel and
pitch channel EXP curves are cleared.

and G ) to increase and decrease the selected value.
For the side B rate, press the D key and set as done
for Side A.
To use the exponential curve in dual rates, press the
A key, then press the NXT L key.
Press the EX1 I key to activate the EXP1 mode,
or press the EX2 L key to activate the EXP2 mode.
Set the Side A and Side L rates as described previously.
To choose linear response mode, press the A key,
then press the NXT L key. Select the INH H key to
choose the linear mode. The A and B rate curve settings
are automatically made.
D/R switch selection and ON/OFF setting
Call the switch setting screen by pressing the SWT
O key. For a description of the switch setting method,
see page 40. If you'd like the dual rates to be turned on
automatically by stick position, press the STK O but-
ton while in the switch selection screen. For example,
you could have dual rates turned on when the throttle
stick passed a defined position.
Dual Rate circuits B and C are set the same way as for
Circuit A.
To Exit, press the END N key. This returns you to
the D/R A-to-C selection screen. Press the END N key
again to return to the Condition Menu.
