Expo
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 making it
easier to drive at high speeds in a straight line while still allow-
ing for maximum turning radius. While sensitivity with positive
Expo is decreased around neutral, it increases the sensitivity
near the end of travel.

Bind
Binding is the process of teaching the receiver the speciic
transmitter’s code called GUID (Globally Unique Identiier) and
storing failsafe values. When a receiver is bound to a
transmitter/model memory, the receiver will only respond to that
speciic transmitter/model memory (see ModelMatch for more
information).
Note:
If a receiver is not bound to a specific model memory, it
will not operate.
Bind Transmitter to Receiver
1. Insert a bind plug in the receiver’s BIND port.
2. Power on the receiver and wait until the receiver LED begins
to blink (approximately 5 seconds).
3. Power on the transmitter.
4. Make sure the model number you desire shows on the Main
Screen. Go to the Model Select Screen to change the active
model number as needed.
5. Go to the transmitter’s Bind Screen and highlight BIND.
6. Move steering wheel, throttle trigger and AUX channel
(where used) to desired Failsafe positions and hold them in
that position during the bind process.
7. Press the Rolling Selector to start the bind process (which
also stores Failsafe positions).
8. BIND will lash on the screen for a few seconds then stop
and the receiver LED will show a solid light, indicating the
bind process is complete.
9. When the bind process is complete, remove bind plug and
store plug in a convenient place.
NOTICE:
If the bind plug is not removed from the receiver,
the receiver will enter bind mode the next time the receiver is
powered on.
Failsafe
Failsafe positions are also set during binding. In the unlikely
event that the radio link is lost during use, the receiver will drive
the servos to their pre-programmed failsafe positions (normally
full brakes and straight steering). If the receiver is turned on
prior to turning on the transmitter, the receiver will enter the fail-
safe mode, driving the servos to their preset failsafe positions.
When the transmitter is turned on, normal control is resumed.
Failsafe servo positions are set during binding.
Note:
Failsafe activates only in the event that signal is lost from
the transmitter. Failsafe will NOT activate in the event that re-
ceiver battery power goes down or power to the receiver is lost.
The Bind Screen shows the active model and supports binding
the active model memory to a receiver.
