ADJUSTING THE ELECTRONIC SPEED CONTROL
The EVX-2 electronic speed control is factory set and should not require any
adjustments. These instructions are provided for your reference.
Battery Settings (Low-Voltage Detection Setting)
The Low-Voltage Detection circuitry constantly monitors the battery voltage.
When the battery voltage begins to reach the minimum recommended discharge
voltage threshold for LiPo battery packs, the EVX-2 will limit the power output
to 50% throttle. When the battery voltage attempts to fall below the minimum
threshold, the EVX-2 will shut down all motor output. The LED on the speed
control will slowly blink red, indicating a low voltage shutdown. The EVX-2 will stay
in this mode until a fully charged battery is connected.
Your model comes equipped with two Traxxas battery packs. The EVX-2 speed
control’s Low-Voltage Detection has been disabled for best performance with
these batteries. The speed control’s LED will glow red when it is turned on,
indicating Low-Voltage Detection is disabled. Be certain to activate Low-Voltage
Detection if you install LiPo batteries in your model.
Never use LiPo batteries
while Low-Voltage Detection is disabled.
Verify that Low-Voltage Detection is DISABLED:
1. Turn on the transmitter (with the throttle at neutral).
2. Connect fully charged battery packs to the EVX-2.
3. Press and release the EZ-Set button to turn the EVX-2 on. If the LED is solid red,
then the Low-Voltage Detection is DISABLED (not safe to use LiPo batteries).
If the LED is solid green, then Low-Voltage Detection is ACTIVATED.
To activate Low-Voltage Detection (LiPo setting):
1. Make sure the LED on the EVX-2 is on and shines red.
2. Press and hold the EZ-Set button (the
LED will turn off) (A). After ten seconds,
the motor will beep twice and the LED
will shine green. Release the button (B).
3. Low-Voltage Detection is now ACTIVATED.
To disable Low-Voltage Detection (NiMH setting):
1. Make sure the LED on the EVX-2 is on and shines green.
2. Press and hold the EZ-Set button (the LED
will turn off) (A). After ten seconds, the
motor will beep three times and the LED
will shine red. Release the button (B).
3. Low-Voltage Detection is now DISABLED.
Transmitter Adjustments for the EVX-2 ESC
Before attempting to program your EVX-2, it is important to make sure your TQi
transmitter is properly adjusted (set back to the factory defaults). Otherwise, you
may not get the best performance from your speed control.
The transmitter should be adjusted as follows:
1. Turn the transmitter off.
2. Hold both MENU and SET.
3. Turn the transmitter on.
4. Release MENU and SET. The transmitter LED will blink red.
5. Press MENU once. The transmitter LED will blink red twice repeatedly.
6. Press SET to clear settings. The LED will turn solid green and the transmitter is
restored to default.
Setup Programming
(Calibrating your ESC and transmitter)
Read through all of the following programming steps before you begin. If you
get lost during programming or receive unexpected results, simply unplug the
batteries, wait a few seconds, plug the battery packs in, and start over.
1. Disconnect each of the motor wires between the EVX-2 and the
motors. This is a precaution to prevent runaway when the speed
control is turned on before it is programmed.
2. Connect two fully charged battery packs to the EVX-2.
3. Turn on the transmitter (with the throttle
at neutral).
4. Press and hold the EZ-Set button (A).
The LED will first turn green and then red.
Release the EZ-Set button.
5. When the LED blinks RED ONCE, pull the throttle
trigger to the full throttle position
and hold it there (B).
6. When the LED blinks RED TWICE, push the
throttle trigger to the full reverse and hold it
there (C).
7. When the LED blinks GREEN ONCE, programming is complete.
The LED will then shine green or red (depending on Low-
Voltage Detection setting), indicating the EVX-2 is on and at
neutral (D).
EVX-2 Operation
To operate the speed control and test the programming, place the vehicle on a
stable block or stand so all of the drive wheels are off the ground. Reconnect the
motor wires. Always make sure that objects and fingers are clear of the wheels.
Note that in the steps below, Low-Voltage Detection is DISABLED (factory default with NiMH
batteries) and the LED shines red. If Low-Voltage Detection is ACTIVATED (factory default
with LiPo batteries), the LED will shine green instead of red in the steps below.
Never use LiPo
batteries while Low-Voltage Detection is disabled.
1. With the transmitter on, press the EZ-Set button for ½ second, until the LED
shines red, then immediately release the button. This turns on the EVX-2. If you
press and release too quickly, you may hear the steering servos jump but the
LED may not stay on. (
Note
: If the throttle is not at neutral or if the throttle trim has
been altered, the LED will turn off after one second and the wheels may begin to
drive.)
2. Apply forward throttle. The LED will turn off until full throttle power is reached.
At full throttle, the LED will shine red.
3. Move the trigger forward to apply the brakes. Note that braking control is fully
proportional. The LED will turn off until full braking power is reached. At full
brakes, the LED will shine red.
