Exponential - Spectrum DX3S User Manual

exponenTIal

Exponential is used to affect the response rate of the
steering, throttle and/or brake. On the DX3S, positive
Exponential will reduce steering sensitivity around neutral
making it easier to drive at high speeds in a straight line
while still allowing for maximum turning radius. While
sensitivity with positive Exponential is reduced around
neutral, it increases the sensitivity near the end of travel.
The DX3S' Exponential function (Expo for short) allows
independent Expo values in each direction on the
steering and throttle channels.

From the list screen use the Rolling Selector to highlight
the Exponential function.
Press the Rolling Selector to enter the Exponential
function. The Expo screen will be displayed as shown on
this page.
Rotate the Rolling Selector and highlight the values next
to the desired channel you wish to adjust.
ST= Steering
TH= Throttle and brake
Press the Rolling Selector to enter the highlighted
channel's Expo function.
Rotating the Rolling Selector will now adjust both the
upper and lower values simultaneously. If you desire to
adjust the left or right Expo values independently, move
the corresponding channel's wheel or throttle, and that
value alone will be highlighted (e.g. 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 DX3S features "sticky gooey."
When the corresponding channel is moved
to the desired position and released, as
illustrated above, 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 trigger in the desired position. To highlight
both values again after moving the control
in one direction, simply press the Rolling
Selector twice with the control centered and
both values will be highlighted.
To return to the Main screen press and hold the Rolling
Selector for more than three seconds.
