Mounting the Speed Control
Mount the Tazer
™
12T ESC in the location specified by your
vehicle’s instruction manual. Use the double-sided foam tape
(included) to secure the speed control in position.
NOTE
: Be sure all wiring connections can be reached
prior to mounting.
Use double-sided foam tape to secure the side of the switch to a
convenient location on the chassis or shock tower.
Wiring Diagram
Wiring the Receiver
NOTE
: The Tazer 12T uses the motor battery to supply
power to the receiver through the servo wires. There is
no need for a separate receiver battery.
• See your radio’s instruction manual for proper
connection. Typically, channel 2 is used to control
the throttle.
• There are 3 wires involved in the universal receiver
connector. It is directly compatible with JR
®
, Hitec,
Airtronics Z, New KO and Futaba J systems.
• Older Airtronics or KO radio systems must use a
modified wiring order.
• The positive (red) and negative (brown) wires must
be reversed to operate with these radio systems. To
remove the wires from the plug, use a small jewelers
screwdriver to pry up the plastic tab associated
with each wire. Gently slide the brown wire out of the
plug. Repeat on the red wire and replace in the
opposite positions.
• Install the plug referencing the wire colors on the
steering servo for proper polarity.
Motor Capacitors
If the motor you are using (12 turns or more) does not have
3 capacitors already attached, you must install them. The
monolithic capacitors help prevent motor noise which
lessens radio glitches. Some motors have internal capacitors
that are not visible without removing the endbell. Check the
motor’s instructions to confirm if capacitors are present in
your motor. If your motor does not have capacitors, they can
be purchased at your local hobby shop. Follow the directions
below for proper connection.
1. Using a small file, scuff up an area on the motor can between
the positive and negative tabs (see figure 2).
2. Take one of the capacitors and solder one
wire to the positive motor tab with the
other wire positioned over the scuffed
area on the motor housing (see figure 3).
3. Use another capacitor and solder one
wire to the negative motor tab with the
other wire positioned over the scuffed
area as well.
4. Solder both wires to the motor housing
(see figure 4). A high wattage soldering
iron may be necessary.
5. Solder the third capacitor from the
positive to the negative motor tabs
(see figure 5).
6. Use side cuts to remove excess
capacitor wires.
Some forward-only ESCs require a shotky
diode attached to the motor for noise
suppression. Be certain there IS NOT a
diode attached to the motor when using the
Tazer 12T or any other reversing electronic
speed control.
Connecting the Motor Wires
If your motor has pre-attached male bullet connectors, press
the orange motor wire into the plug that is wired to the positive
motor terminal. The black wire is
connected in the same manner to the
negative motor tab (see figure 6).
If your motor does not have male
bullet connectors, you may purchase
them from your local hobby shop.
(“Motor Connector Wire DLR1055”).
Caution
: To detour glitches caused by RF (radio
frequency) noise, route all wires and the receiver
antenna away from motor leads. Secure with tie wraps
(not included).
Connecting the Battery
The Tazer 12T comes pre-wired with a Tamiya-style connector,
compatible with most battery packs. Use battery packs from
4-cell (4.8-volt) to 6-cell (7.2-volt) sub-C size battery pack.
1. Be sure the on/off switch is in the “off” position.
2. Connect a fully charged battery pack to the speed control’s
battery connector.
Adjusting the Transmitter
NOTE
: Refer to the radio instructions for specific
information on transmitter setup.
1. Set the “throttle reversing” switch to the NORMAL position.
(This may need to be reversed on some brands of radios.)
2. Set the “throttle trim” to the CENTER position.
3. Set the “throttle exponential” to MINIMUM or ZERO.
4. Set the “ATV” to 100%.
5. If your transmitter has an adjustable trigger (or stick) position,
move it to the 70/30 position.
Speed Control Programming
NOTE
: While in the programming mode, no power is
applied to the motor.
1. Turn on the transmitter’s power switch. (Be sure the transmitter
batteries are fully charged).
2. Turn the ESC switch on.
3. Press and release the setup button. The red and green LEDs
will light.
4. Move the throttle to the full throttle position and press the
programming button. The green LED will remain lit and the red
LED will go out. (If the ESC does not sense throttle movement
in 3 seconds by the transmitter, it will exit the programming
mode and you will have to begin again.)
5. Now move the throttle to full reverse and press the
programming button. The red LED will glow and the green
LED will go out.
6. Return the throttle stick to neutral and press the programming
button. The green LED will glow and the red LED will go out,
indicating programming is complete.
During normal operation, the green LED indicates neutral and the
red LED indicates full forward and full reverse.
Selecting Forward Only or
Forward/Reverse Mode
The Tazer 12T has 2 modes: Forward only mode and Foward
and Reverse mode. The Forward Only mode can be selected for
racing purposes. When the ESC is powered on, the LED will flash
for 2 seconds: the color of the LED indicates which mode the
ESC is operating in:
Forward and Reverse Mode–The Green LED will Flash
Forward Only Mode–The Red LED will flash.
To change modes, push the set button and turn on the ESC. The
LED will flash, indicating the new mode has been selected. Note
the color of the LED to determine the mode of your ESC.
