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
extremes of throw. The sensitivity around center can be tailored using the
Exponential function to precisely adjust control feel.Exponential rates can be
controlled by their respective rate switches (aileron, elevator and rudder),
or combined on a flight mode switch. Exponential is available for the aileron,
elevator and rudder channels. Expo values are adjustable from -100% (full negative
expo), LIN (linear), and +100% (full positive expo). The factory default settings for
both the 0 and 1 switch positions are LIN or 0%. Either switch position may be
selected to give any desirable EXPO rate by placing the switch in the desired
position and adjusting the value accordingly.
Note: A negative (-) Expo value will increase sensitivity around neutral, and a
positive (+) Expo value will decrease sensitivity around neutral. Normally a
positive value is used to insensitize control response around neutral.
◇
To Adjust the Exponential
Press the DOWN and SELECT keys simultaneously to access the Function Mode.
In Function Mode, use the UP or DOWN keys to select the DUAL RATE AND
EXPONENTIAL screen.Press the INCREASE or DECREASE key to select the
desired channel (AILE, ELEV or RUDD).Move the selected channel's dual rate
switch to the desired position, 0 or 1.Press the SELECT key until EXP is highlighted.
Adjust the Expo rate values for the selected switch position using the INCREASE
or DECREASE keys.
◆
Auto Dual Rate EXP
The Auto Dual Rate and Expo function allows Expo and Dual Rate values (aileron,
elevator and rudder) to be automatically selected in each flight mode (Normal,
◇
To Adjust the Auto Dual Rate
Press the DOWN and SELECT key simultaneously to access the Function Mode.
Press the UP or DowN key until the AUTO D/R EXP screen appears on screen.
Use the select key to select NORMAL, ST1 ST2 or NORMAL mode.
When selected, press the INCREASE or DECREASE key to select DUAL RATE,
P-1, P-2 or INHIBIT.
Note: The actual dual rate values are setted in the Dual Rate and Expo screen.
See Page 84.
◆
Reverse Switch
The Reverse Switch function allows electronic means of reversing the servo’s throw.
Servo reversing is available for all seven channels.
◇
Accessing the Reverse Switch Function
Press the SELECT key to access the desired channel.
Press the INCREASE or DECREASE keys to reverse the servo direction for that
selected channel.
