Control Attitude Settings for Control Functions 2, 3 and 4
The dual rate/expo function allows users to assign
switches and phases to change or influence the con-
trol deflections and characteristics of channels 2, 3
and 4.
To change these settings, from the main display press
the FUNCTION menu gear icon (blue “F”) to bring up
the FUNCTION submenu screen:

This procedure is identical for all models, but the
channel page labeling differs between models. Refer
to the model type to understand the different values in
the field to the right of the CH line.
For all CARS, BOATS or DRONES, the channel set-
ting pages of this submenu are labeled CH2, CH3 and
CH4, as shown below:
For all HELICOPTERS, the channel setting pages of
this submenu are labeled ROLL (CH2), NICK (CH3)
and TAIL (CH4), as shown below:

Tip
The 7 individual characteristic curve points for control
function CH1 (throttle/brake) can be set in the follow-
ing sections: all models except helicopters FUNCTION
submenu THR.CRV (page 128), and helicopter models
FUNCTION submenu THR.CRV (page 160).
Dual Rate enable the control surface deflection limits
to be changed while still retaining full stick movement,
i.e. ‘normal’ deflection plus a setting for decreased/
increased deflection limits at full stick movement. D/R
acts independently from functions that associate a
single servo or are actuated thorough a complex mix-
er or coupling function by multiple servos. (Refer to
the BASE submenu CTL Set (page 90) or Definition
of Terms Control Function (page 24) for additional
information.)
The control deflections can be set for each switch
position between 0 and 125% of the normal control
travel.
EXP allows users to adjust the sensitivity of the con-
trol surface deflection around smaller stick move-
ments. For example, the elevators are barely moved
when the stick moves around its central position, but
