With the same technology as Novak’s top-of-the-line GTX, the GTS Pro Sport ESC is the
perfect choice for those wanting to step up to the exciting world of racing.
Built with state-of-the-art components just like our World Champion GTX speed control, high-frequency operation for ultra-smooth
throttle response, and thermal overload protection circuitry, the GTS is ready to help you make your mark in today’s racing community.
The GTS also features the ease & convenience of Novak’s original One-Touch programming, user-replaceable
power wires, power capacitor, & input harness--just what you need to get to the top of the podium!
To get the most out of your GTS, PLEASE READ ALL INSTRUCTIONS before using
STANDARD REPLACEMENT POWER CAPACITORS
[#5677]
An external power capacitor is installed, and
MUST BE USED
to
maintain cool and smooth operation.
Refer to Fig.5 Set-Up Photo
Replacement Power Capacitors available in Novak kit #5677.
LARGE POWER CAPACITORS
[FOR EXTREME RACING]
[#5675]
Novak Power Capacitor that comes with the World Champion GTX
speed control--for additional ESC cooling & improved performance.
Optional Large Power Capacitors available in Novak kit #5675.
RACING SCHOTTKY MOTOR MODULES
[#5636]
The GTS has a built-in Schottky diode and should not require an
external one for most usage
--using an external Schottky will optimize
the ESC’s braking and motor performance (recommendeed for racing).
Racing Schottky Motor Module is available in Novak kit #5636.
MOTOR CAPACITORS
[#5620]
Additional motor capacitors are available in Novak kit #5620.
14G SUPERFLEX SILICONE POWER WIRE
[#5500 & 5505]
Replacement GTS battery & motor wire is available in Novak kits #5500
(36”red & 36”black) & #5505 (36”red & 36”blue).
INPUT SIGNAL HARNESS
[#5315 & #5320]
The user-replaceable input signal harness is available in both short
and long lengths to fit different applications.
4.5” harness in Novak kit #5315, and 9.0” harness in kit #5315.
WATER & ELECTRONICS DON’T MIX
!
Never allow water, moisture, or other foreign materials to get
inside the speed control or on the PC Board.
Damage from water or foreign material will void the warranty!
DISCONNECT BATTERIES WHEN NOT IN USE
Always disconnect the battery pack from the speed control
when not in use to avoid short circuits and possible fire hazard.
4 TO 6 CELLS ONLY
Never use fewer than 4 or more than 6 cells (7.2 volts DC) in
the vehicle’s main battery pack.
NO REVERSE VOLTAGE
!
Reverse battery polarity can damage speed control––Disconnect
the battery immediately if a reverse connection occurs.
POWER CAPACITOR REQUIRED
An external power capacitor is supplied & installed, and
MUST
be
used with your GTS.
Failure to use Novak Power Capacitor will
result in higher ESC operating temperatures & will void warranty!
TRANSMITTER ON FIRST
Always turn on the power of the transmitter first so that you
will have control of the vehicle when you turn it on.
INSULATE WIRES
Always insulate exposed wiring with heat shrink tubing or
electrical tape to prevent short circuits, which can damage ESC.
NO SOLVENTS
Exposing the speed control’s Lexan
®
case to any type of
solvents will damage the plastic.
NO CA GLUE
Exposure to CA glue or its fumes can cause damage to internal
components of the speed control and result in premature failure.
For proper ESC operation, adjust transmitter as follows:

•NOT ALL TRANSMITTERS HA
VE ALL THESE ADJUSTMENTS•
With GTS connected to (at least) a receiver & a charged battery pack:
1. TURN ON THE TRANSMITTER’S POWER
2. TURN ON THE SPEED CONTROL’S POWER
3. PRESS & HOLD GTS’S ONE-TOUCH/SET BUTTON
With transmitter throttle at neutral,
press and hold the SET button
.
4. CONTINUE HOLDING SET BUTTON UNTIL RED LED COMES ON
5. RELEASE GTS’S SET BUTTON AS SOON AS LED TURNS RED
6. PULL TRANSMITTER THROTTLE TO FULL-ON POSITION
Hold it there until the
green status LED
turns solid green
.
Note: Motor will not run during programming even if connected.
7. PUSH TRANSMITTER THROTTLE TO FULL-BRAKES
Hold it there until the
green status LED
blinks green
.
8. RETURN TRANSMITTER THROTTLE TO NEUTRAL
Red status LED
will
turn solid red
, indicating that throttle is at neutral,
and proper programming has been completed--you’re done.
NOTE: If transmitter setting are changed, programming must be repeated.
If you experience any problems, turn off ESC and repeat programming.
You do not need to repeat One-Touch programming after changing motors.
trouble-shooting guide
Steering Channel Works But Motor Will Not Run
• Check motor connections. Check motor and brushes.
• Make sure input signal harness is plugged into throttle channel of receiver
and the ESC. Check throttle channel operation with a servo. Check wiring
color sequence of receiver signal harness.
• Possible thermal shut-down (red status LEDs flashing)––Check motor,
brushes, & drive train. ESC is being over-loaded.
• Possible internal damage––Refer to Service Procedures.
Receiver Glitches/Throttle Stutters During Acceleration
• Receiver or antenna too close to ESC, power wires, battery, or motor.
• Bad connections––Check wiring and connectors.
• Motor brushes worn––Replace brushes.
• Excessive motor current––Use milder motor or smaller pinion gear.
• External Power Capacitor damaged/not installed––Replace Power Capacitor.
Motor and Steering Servo Do Not Work
• Check wires, receiver signal harness wiring & color sequence, radio system,
crystals, battery & motor connectors, and battery pack.
• Possible internal damage––Refer to Service Procedures.
Model Runs Slowly/Slow Acceleration
• Check motor and battery connectors––Replace if needed.
• Bad battery or motor––Check operation with another.
• Incorrect transmitter/ESC adjustment––Refer to Steps 4 & 5.
• External Power Capacitor damaged/not installed––Replace Power Capacitor.
• Schottky diode damaged––If using external Schottky, check that diode is
installed correctly/Refer to Step 2. Possible internal Schottky damage.
Motor Runs Backwards
• Motor wired backwards––Check wiring and reverse.
• Backwards motor timing––Reverse motor end bell.
ESC Is Melted Or Burnt/ESC Runs With Switch Off
• Internal damage––Refer to Service Procedures.

age from excessive force when using the One-Touch/SET button or from disassem-
bling case, tampering with internal electronics, allowing water, moisture, or any other
foreign material to enter ESC or get onto the PC board, incorrect installation/wiring of

Be sure to mount the GTS where its power wires are away from
other electronics, and will not interfere with any moving parts.
• Mount GTS to the vehicle’s chassis with the included double-sided
tape (use two layers of other double-sided tapes for adequate damping).
• Mount Power Capacitor to chassis with double-sided tape or tie-
wrap (if using tie-wraps, be careful not to dent body of Power Cap).
If Power
Cap becomes dented/damaged, ESC failure can occur
--replace
immediately.
Longer Power Capacitor wires decrease performance
.
• Mount the ON/OFF switch in a position where it will be easy to
access. You can use a 4-40 or smaller screw to mount the ON/
OFF switch to a hole in the chassis, or use the included double-
sided tape to mount the switch in the vehicle.
• Be sure receiver & antenna are mounted as far from ESC, power
wires, battery, and servo as possible--these components all emit
RF noise when throttle is being applied. On graphite or aluminum
chassis vehicles, it may help to place receiver on edge with crystal
& antenna as far above chassis as possible.
Note: Mount antenna as close to receiver as possible--trail any excess wire off top
of antenna mast (cutting or coiling excess antenna wire will reduce radio range).
