Binding the Radio System
Steps to Re-Bind
1. Ensure that the transmitter and vehicle are both turned
off.
2. Using the supplied Bind plug (which looks like a
standard receiver plug with a wire loop installed) insert
the Bind plug into the receiver slot labeled “BIND”.
Looking down on the receiver this slot would be below
the LED and is the farthest from the LED, or nearest to
the corner of the receiver. Note: You do not need to
remove any of the other plugs to re-bind.
3. With the Bind plug installed, turn on the vehicle. Notice
a blinking Orange LED within the receiver.
4. Now you are ready to turn on the transmitter. You
should notice on the back of the transmitter a similar
blinking Orange LED under the translucent cover.
5. Both the receiver and transmitter blinking Orange LED
will stop blinking and become solid, indicating they
have “bound” themselves together.
6. Turn off both the vehicle and the transmitter then
remove the Bind plug from the receiver. Failing to
remove the Bind plug will cause the receiver to attempt
to re-bind every time you turn on the vehicle and
transmitter.
7. Turn on both the vehicle and transmitter to ensure
operation. If the transmitter does not control the
vehicle, please repeat steps 1–6. Should this not correct
the problem, please call Horizon Service/Repair for
further assistance.
8. The Bind process is complete. Your vehicle’s radio
system should be ready for use.
Using the EPA Adjustment
The Endpoint Adjustment (EPA) feature of the Losi DSM radio
allows you to set the amount the servo travels when you turn
the steering wheel or push/pull the throttle. This is especially
helpful to prevent the servos from stalling with normal
operation.
Steering: First set the steering trim so the truck goes
straight without touching the steering wheel. Lift
the front of the truck off of the ground and turn
the steering wheel to the right. Use the included
mini screwdriver to adjust the pot marked “right”
back and forth stopping when the wheels can
turn to the right no more. Repeat this procedure
turning left using the pot marked “left”.
Throttle: First set your Throttle/Brake trim. With the engine
not running, remove the air cleaner. Pull full back
on the throttle trigger and note the position of
the carburetor barrel. Adjust the pot marked
“throttle” back and forth so that the barrel just
reaches wide open (going further will only hurt
performance).
Brake:
Release the trigger and push it forward. Turn the
pot marked “brake” counterclockwise (away from
the “+”) as far as it will go. Now turn it clockwise
(toward the “+”) until it stops moving. This will
give you maximum push brake.
