Exponential is used to affect the response rate
of the steering, throttle and/ or brake. Typically
positive Exponential is used for steering, reducing
steering sensitivity around neutral, making it
easier to drive the car at high speeds in a straight
line but exponential still allows for the maximum
turning radius.
The DX3R’s Exponential function (Expo for short)
allows independent Expo values in each direction
of all three channels (steering, throttle and
auxiliary). A graphic illustration displays the effect
of exponential adjustment.
To aCCess The
exponenTIal funCTIon:
From the List screen rotate the roller to highlight the
Exponential function.
Press the roller to enter the Exponential function.
The Expo screen will be displayed as shown above.
Rotate the roller to highlight the desired channel that
you wish to adjust the travel.
ST= Steering
TH= Throttle and brake
AX= Auxiliary channel 3
Press the roller to enter the highlighted channel’s
Expo function.

Rotate the roller to highlight the values at the
bottom of the screen; then press the roller to
select the values.
Rotating the roller will now adjust both the right and
left values simultaneously. If you desire to adjust
the right or left Expo values independently, move
the corresponding channel’s wheel, throttle stick or
trigger the trimmer that the Aux channel is assigned
to, and that value alone will be highlighted (i.e.
turning the steering wheel to the right will highlight
the right value only and subsequent adjustment will
affect the right travel only).
Note: Positive and negative Expo values are
available. A positive Expo value results in the
center being less sensitive (desirable most of
the time) while a negative value increases the
sensitivity around center (normally not used).
Note: The DX3R features “sticky gooey.”
When the corresponding channel is moved
in the desired direction as illustrated
above and released, the value on that side
remains highlighted. Moving the channel
in the opposite direction will then highlight
the opposite value direction. This allows
convenient independent exponential
adjustments without having to hold the wheel
or stick in the desired position. To highlight
both values again after moving the wheel in
one direction, simply press the roller once
with the trigger centered and both values will
be highlighted.
