step 4–MOUNTiNG ESC
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 tiewrap (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 doublesided 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).
step 5–transmitter adjustments
A. Set HIGH ATV or EPA to maximum setting. |
•NOTALL |
|
For proper ESC operation, adjust transmitter as follows: |
|
|
[amount of throw at full throttle] |
TRANSMITTERS |
|
B. Set LOW ATV, EPA, or ATL to maximum setting. |
||
|
||
[amount of throw at full brakes] |
|
|
C. Set EXPONENTIAL to zero setting. [throttle channel linearity] |
|
|
D. Set THROTTLE CHANNEL REV. SWITCH to either position. |
HAVE |
|
E. Set THROTTLE CHANNEL TRIM to middle setting. |
||
ALL |
||
[adjusts neutral position/increases or decreases coast brakes] |
||
F. Set ELECTRONIC TRIGGER THROW ADJUSTMENT to 70% |
THESE |
|
|
||
throttle and 30% brake throw (or 7:3). [older radios only] |
ADJUSTMENTS• |
|
[adjusts trigger throw electronic/digital pistol-grip transmitters] |

G. Set MECHANICAL TRIGGER THROW ADJUSTMENT to position |
|
|
with 2/3 throttle and 1/3 brake throw. |
|
|
[adjusts trigger throw on mechanical/analog pistol-grip transmitters] |

step 6–one-touch programming
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.

To get the most out of your GTS, PLEASE READ ALL INSTRUCTIONS before using
PRECAuTIONS
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.
optional accessories
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
