release the button. You are now in programming mode.
6. Pull the transmitter throttle trigger to the full throttle
position. Hold it there until the status LED turns solid green.
Note: The motors will not run during programming even if
they are connected to the speed control.
7. Push the transmitter throttle trigger to full reverse. Hold it
there until the status LED blinks green.
8. Release the transmitter throttle trigger allowing it to return to
neutral. The status LED will turn solid red, indicating that the
throttle is at neutral and the programming has been
completed.
9. Connect the motors to the speed control. Connect the red
speed control wires to motor's red positive (+) leads. Connect
the black speed control wires to motor's negative (-) leads.
Make sure the bullet connectors snap together securely. Refer
to the wiring diagram on page 25 for assistance.
The EVX speed control is now programmed & ready to go!
If the transmitter settings are changed, it will be necessary to
complete the programming sequence again.
If the SET button is released before the LED turns solid red in
step 5, the LED will blink 7 times and then return to the
normal operation mode.
If you experience any problems during programming, turn
off the speed control and repeat the programming steps.

Speed Control Throttle Profile Selection

The speed control is factory set to Profile #1
(forward/reverse/brake operation). To disable the reverse (Profile
#2), or reduce the reverse speed to 25% (Profile #3), follow these
steps. The speed control should be connected to the receiver
and the transmitter adjusted as described above.
1. Connect two fully charged battery packs to the speed control.
Connect one JST plug (RED & BLACK wires) to one battery
pack. Connect the other JST plug to the other battery pack.
