Elevator for example), Press R or L to shift the status between
nomal and reverse. These are two status for option. And the
default settin g is Normal. All Channels Reverse Switch like:

g ation
to desired item Elevation of U. Press R or L to increase or
decrease the servo travel ran g e. The adjustment ran g e is
from 0.0% to 150.0%. The factory default is 100.0%.

Press UP or DN to move navi g
ation mark to desired item D of ELEV. Press R or L to increase or decrease
the servo travel ran g e. The ran g e is from 0.0% to 150.0%. The factory default is 100.0%.
All other channel's Travel Adjust like Aileron, Throttle, Rudder, Gear, Pitch and Aux2 can be referred to ELEV
travel Ajust. Press EXT to exit after settin g finished.
3.3 Sub Trim
NOTE: Sub Trim is used to fine tune the servo neutral position durin g setup. In order to avoid pushin g the
servo beyond it's limits and possibly causin g dama g e it is advised to first mechanically adjust the servo arm/bell
crank to be as close to the neutral point as possible. Only when this is complete may sub trim be used to
make a final a djustment.
Settin g method:
Press ENT to enter Main Menu, Press UP or DN to move
the navi g ation mark to desired item Function Menu. Press
ENT to enter Function Menu, Press UP or DN to select

Press EXT to exit after adjustment finished.
3.4 Dual rate and Exponential
Dual Rate/Exponential is a function which permits a chan g e in behavior of the control sticks between pre-
defined settin g s. Dual Rate alters the maximum and minimum servo travel available, Expo has no effect on
the maximum or minimum travel but decreases or increases the sensitivity to stick movement in an exponential
manner. One use of Dual Rate/Expo is to reduce the sensitivity of the controls when landin g .
