◇To Enter the Function List Mode
● Turn the transmitter on.
● From the main screen, press the UP and SELECT keys simultaneously.
● The system is in Function List Mode now and will display a list of all the available
functions .
● Use the UP and DOWN keys to Scroll through the available function.
● Press DOWN and SELECT to enter a selected function.
◇To Exit the Function List Mode
● Press the DOWN and SELECT keys simultaneously twice. The system will return
to the main screen.
◆Dual Rate and Switch Select
The D/R switch select function allows the dual and expo rates to be selected via
individual switches (aileron, elevator and rudder D/R switches) or to be
conveniently combined
on a single switch. When combined to a single switch the following switch options
are available:
● COM AILE: Aileron D/R switch
● COM ELEV: Elevator D/R switch
● COM RUDD: Rudder D/R switch
● FLAP 2: Flap switch in the lower position
● FLAP 0: Flap switch in the upper position
● INDIVID: D/R activated by it’s individual aileron, elevator and rudder switches.
◇To Activate Dual Rate and Switch Select
Press and hold the DOWN and SELECT keys simultaneously to enter system mode.
Press the UP or DowN key until D/R SWITCH SEL appears on the screen.
Press the INCREASE or DECREASE keys to select the desired switch(es) you wish
to operate the D/R and Expo function.
and selectedwith 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 authourity 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.
Dual and Expo rates can be controlled by their respective dual rate switches or by
one common switch. 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.
◇To Adjust the Dual and Expo Rates
Press the DOWN and SELECT keys simultaneously to access the Function Mode.
In Function Mode, use the UP or DOWN keys to select the D/R or EXP screen.
Press the INCREASE or DECREASE key to select the desired channel.
Press the SELECT key to highlight the D/R or EXPO function.
Adjust the dual rate values for the selected switch position using the INCREASE or
DECREASE key.

◆Dual Rate and Exponential
The Dual Rate and Exponential function allows two control rates to be programmed
he Dual Rate and Expo functions for aileron, elevator and rudder can be combined
on a single switch, high or low rates to be selected via one switch. The choices for
this are found on the D/R SWITCH SEL screen in the System Setup Mode for
Airplanes.(have a look at page 50.)
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
