1. INSTALL MOTOR CAPACITORS
Electric motors generate radio noise that can interfere
with your receiver and cause radio problems. Included
in the accessory kit with the speed control are three
0.1
µ
F (50V) non-polarized, ceramic capacitors.
These
capacitors
must be installed on every motor to help
reduce the noise generated by the motor and also to
prevent possible damage to the speed control. Extra
0.1
µ
F capacitors are available in
Novak kit #5620
.
Solder 0.1
µ
F (50V) capacitors between:
• POSITIVE (+) motor tab & NEGATIVE (
-
) motor tab.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (
-
) motor tab & GROUND tab*.
*If your motor does not have a ground tab, solder the
capacitor leads to the can of the motor as shown below.
Negative (-) motor tab
0.1
µ
F Capacitors
Schottky diode
Optional Schottky diode*
Positive (+) motor tab
Ground/motor can
* A second Schottky diode may be needed if using a low turn modified motor.
2. INSTALL SCHOTTKY DIODE
Solder the lead
CLOSEST
to the silver stripe on the body
of the Schottky diode to the
POSITIVE
(+) motor tab.
Solder the lead
OPPOSITE
the silver stripe on the body
of the Schottky to the
NEGATIVE
(-) motor tab.
If installed backwards, a Schottky diode will be destroyed. The
body of a bad diode will normally crack open. Replace only
with Schottky diodes that have a minimum rating of 35 volts/
8 amps. Schottky diodes are available in
Novak kit #5640
.
3. CONNECT SPEED CONTROL TO THE RECEIVER
After the proper input plug plastic has been installed
to match the receiver (Refer to Step 1), plug the speed
control into the
THROTTLE CHANNEL
of the receiver.
4. CONNECT SPEED CONTROL TO THE BATTERY PACK
Cut the
BLACK
wire of speed control to the desired
length and strip about 1/4” of insulation off the end.
Solder to the
negative
side of a completely charged 4
to 10 cell battery pack (1.2 volts DC/cell).
Strip a short section of insulation (1/4”-3/8”) from the
middle section of the
RED
wire of speed control where
it will attach to
positive
of battery pack. Solder the
stripped section of
RED
wire to
positive
of battery pack.
5. CONNECT SPEED CONTROL TO THE MOTOR
Cut the
BLUE
wire of speed control to the desired
length and strip about 1/4” of insulation off the end.
Solder to the
negative
tab of the motor.
Cut the
RED
wire of speed control (after battery pack
connection) to desired length and strip about 1/4” of
insulation off the end. Solder to
positive
tab of motor.
TIP:
Twisting the BLUE & RED motor wires one or two times
around each other as they go to motor can help reduce any
radio noise that may be emitted from the power wires.
6. USING PLUGS FOR BATTERY & MOTOR CONNECTION
High-quality/low-resistance connector plugs, such as
Dean’s Ultra Plugs, can also be used to connect the
motor and battery pack. While these connectors make
component changes quick and easy, the connection
will never have the low resistance of a good solder joint.
Be sure to use connectors that can not be connected
backwards, as this will damage the speed control.
It is good practice to use a female connector on the
main battery pack to keep the pack from shorting if
the connector touches a conductive surface.
If you plan to use connector plugs for the battery pack
and the motor, use a male connector on the speed
control wires going to the battery pack and a female
connector on the wires going to the motor. By doing
this, you will avoid plugging the battery pack into the
motor output of the speed control by mistake.
1. DETERMINE BEST ESC MOUNTING LOCATION
The ESC should be positioned away from the receiver
and antenna as shown in Quick Set-Up photo on front
page. Choose a mounting position that will keep the
power wires as short as possible without obstructing
movement of the suspension or the motor pod.
Remember, even though heat sinks are not required,
cooler operating temperatures mean higher efficiency.
So choose a mounting position that allows maximum
airflow through the transistor tabs.
2. INSTALL SPEED CONTROL
Use the included double-sided tape to mount the ESC.
3. INSTALL ON/OFF SWITCH
Determine a convenient place to mount the switch
where it will be easy to get to. Mount the switch using
a piece of double-sided tape or with a screw through
the hole in the base of the switch housing.
4. INSTALL RECEIVER
Mount the receiver as far from the motor, power wires,
battery, and servo as possible. These components all
emit radio noise when the throttle is being applied.
On graphite or aluminum, place the receiver on edge
with the crystal and antenna as far above the chassis as
possible. Mount the antenna close to the receiver and
trail any excess wire off the top of the antenna tube.

STEP 5
SPEED CONTROL PROGRAMMING
Before beginning this step, the speed control should be
connected to the receiver and to a charged 4 to 10 cell
battery pack, and the transmitter should be adjusted.
1. TURN ON THE TRANSMITTER.
2. TURN ON THE SPEED CONTROL
Slide the
ON/OFF
switch to the
ON
position.
3. PRESS AND HOLD SPEED CONTROL’S SET BUTTON
With the transmitter throttle in the neutral position, press
and hold the
SET
button on the speed control until the
status
LED
turns solid red
.
4. RELEASE SPEED CONTROL’S SET BUTTON
5. PULL TRANSMITTER THROTTLE TO FULL-ON POSITION
Hold it there until the status
LED
turns solid green
.
NOTE: The motor will not run during programming even if
it is connected to the speed control.
6. PUSH TRANSMITTER THROTTLE TO FULL-BRAKE
Hold it there until the status
LED
blinks green
.
7. RETURN TRANSMITTER THROTTLE TO NEUTRAL
The status
LED
will
turn solid red
, indicating that the
throttle is in the neutral position and also that proper
programming has been completed.
If transmitter settings are changed during programming,
it will be necessary to complete the programming sequence
once again. If you experience problems during program-
ming, turn off the speed control and repeat programming.
The Tempest Pro should not require an external receiver bat-
tery pack for most racing situations. The built-in Radio-Priority
Circuity™ provides complete control of the steering servo
even after the main battery pack has ‘dumped’ and can no
longer provide the power required to operate the motor.
However, applications using 4-cell set-ups, multiple high-pow-
ered servos, and main battery packs with 8 or more cells
require the use of an external receiver battery pack to pre-
vent overloading or underpowering of the ESC’s voltage
regulator.
Failure to use an external receiver battery pack in
these applications will damage the voltage regulator and void
the product warranty.
1.
Plug the external 5 cell nickel cadmium receiver battery
pack into the battery slot of the receiver.
2.
Leave the speed control’s
ON/OFF
switch in the
OFF
posi-
tion. This switch is not used with this configuration.
3.
Use the
ON/OFF
switch on the external receiver battery
pack to turn the system power on and off.
Note: If using a FET servo with an external receiver battery pack, the
separate power wire from the servo must be connected to the red (posi-
tive) servo wire. For this application do not use the blue wire from the ESC.

MOUNTING INSTRUCTIONS
STEP 6
ADJUSTING THE CURRENT LIMITER
RECEIVER BATTERY PACK
The Tempest Pro ESC is equipped with CLC II current lim-
iting circuitry. The current limiter pot controls the maximum
amount of current going to the motor upon acceleration.
CLC II can be used to prevent excessive amp draw which
wastes energy and overheats the batteries and motor. And,
for slippery tracks, CLC II can be used as traction control.
The Tempest’s CLC II is smooth and effi-
cient. The "OFF" position bypasses the
current limiter for maximum punch. Set-
ting CLC II is simple, just turn the knob to
the desired maximum amp draw. Before
adjusting, set up the car similar to how it will be when
racing. Use practice time at the track to set the current
limiter to match track conditions.
• TO REDUCE WASTED ENERGY
We recommend start-
ing at a high level and adjusting downward to suit the
track conditions. The recommended setting is just above
the point where the CLC II starts reducing the accelera-
tion of the motor.
• TO CONTROL TRACTION ON SLIPPERY TRACKS
We
recommend starting at the lowest setting and adjusting
upward. The recommended setting is just below the point
where the car is difficult to control during acceleration.
• FOR MAXIMUM PUNCH
Turn the knob to the "OFF"
position and punch the throttle!
