FUNCTION LIST
Exponential
The Exponential (Expo) function affects the response rate of the
steering, throttle and/or brake. A positive Steering Expo value, for
example, decreases steering sensitivity around neutral to make it
easier to drive at high speeds in a straight line while still allowing
for maximum turning radius. While sensitivity with positive Expo
is decreased around neutral, it increases the sensitivity near the
end of travel.
To adjust Expo values:
1. Select Throttle or Steering.
2. Scroll Up or Down to adjust the Rate value.
3. Click the scroll wheel to save the selection.
4. Select an OTF switch to activate Exponential.
IMPORTANT: Both 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).
Timer
The DX5 Pro Timer function allows you to program a countdown
timer and stop watch (count up timer) to display on the main
screen. An alarm sounds when the programmed time is reached.
You can program the timer to start using the assigned switch
position or automatically when throttle moves above a pre
programmed position.
Two internal timers are available that show run time for a specic
model displayed on the Main Screen, and a total system timer.
Failsafe
The throttle failsafe position is set during binding. In the unlikely
event that the radio link is lost during use, the receiver will
drive the throttle servo to its pre-Programmed failsafe position
(normally full brakes) and all other channels will have no servo
output. If the receiver is turned on prior to turning on the
transmitter, the receiver will enter the failsafe mode, driving the
throttle servo to its preset failsafe position. When the transmitter
is turned on, normal control is resumed.
IMPORTANT: Failsafe activates only in the event that signal is
lost from the transmitter. Failsafe will NOT activate in the event
that receiver battery power decreases below the recommended
minimums or power to the receiver is lost.
Frame Rate:
For compatibility with all types of servos, four frame rates are
available:
• 5.5ms: Gives the fastest response rate. Digital Servos and a
compatible receiver are required.
IMPORTANT: When 5.5ms frame rate is selected, only two
channels (steering and throttle) are operational.
• 11ms: Offers good response rates and is compatible with
most digital and analog servos (this is the default position).
Works with DSMR surface receivers.
• 16.5ms: Needed for older analog servos.
Works with DSM2
®
surface receivers.
• 22ms: Needed for older analog servos.
Works with DSMR
®
receivers.
IMPORTANT: You should always use the fastest response rate
the servos can handle. This gives the lowest latency and fastest
response. If the frame rate is incompatible with the servo, the
servo will move erratically or, in some cases, not at all. If this
occurs, change the frame rate to the next highest value.
IMPORTANT: Always rebind after changing the Frame Rate.
