step 2–connect motor/battery
step 1–mount esc
Mount the ESC so the power wires are as far away from other electronics as
possible, and will not interfere with the vehicle’s moving parts. Select a loca-
tion with good airflow for cooling the ESC for efficient operation.
1. MOUNT SPEED CONTROL IN VEHICLE
Use the included double-sided tape to mount ESC in vehicle (do not use glue).
Avoid contact with side walls or chassis components to avoid vibration damage.
Be sure receiver & antenna are mounted as far from ESC, power wires, battery,
and servo as possible--These components all emit RF noise.
Note: Mount antenna as close to receiver as possible--trail excess wire off top of
antenna mast (cutting/coiling excess wire reduces radio range--2.4GHz too).
2. INSTALL ON/OFF SWITCH
Use included double-sided tape to mount switch where it will be easy to
access--select a place where it will not get damaged/switched OFF in a crash.
3. SECURE POWER WIRES TO AVOID VIBRATION DAMAGE
Use the included tie-wraps to secure the ESC’s power wires together or to
a point on the vehicle to prevent vibration damage.
Motor connection
1. INSTALL PINION GEAR & ADJUST MOTOR FOR PROPER GEAR MESH
Tighten pinion’s set screw on flat of motor shaft. Align pinion & spur gears.
A. You NEED a small amount of play between the pinion and spur gear
(about thickness of a piece of paper)–check free play at several points around
spur gear to ensure a proper mesh (just in case gears are out of round).
MAKE SURE THE PINION/SPUR GEAR MESH IS NOT TOO TIGHT!
B. Tighten motor mounting screws–Avoid using excessive force that could
break screws or strip the threaded holes in motor.
2. CHECK FOR PROPER GEARING DURING INITIAL RUNS
The brushless motor & ESC should NOT be hotter than 160°F after a 5 minute
run. Lower the gearing until both ESC & motor are under this temperature.
3. CONNECT MOTOR POWER PHASE WIRES TO MOTOR
A. Solder the speed control’s BLUE Phase ‘A’ silicone motor power wire to
the motor’s Phase “A” solder tab.
B. Solder the speed control’s YELLOW Phase ‘B’ silicone motor power wire
to the motor’s Phase “B” solder tab.
C. Solder the speed control’s ORANGE Phase ‘C’ silicone motor power wire
to the motor’s Phase “C” solder tab.
4. CONNECT MOTOR SENSOR HARNESS TO ESC
Insert the 6-pin connector of the motor’s sensor harness into ESC’s sensor
harness socket—connector is keyed and only inserts in one direction.
Battery connection
1. CONNECT ESC’S BATTERY WIRES OR CONNECTOR TO BATTERY PACK
Solder the ESC’s RED & BLACK battery power wires to a fully charged 1S-2S
LiPo, or 4-6 cell NiMH (1.2 VDC/cell) battery pack or to a connector.
To use battery connectors on the ESC, we suggest using low-loss high power
connectors like Dean’s Ultra Plug or the Novak Power Connector.
• Use polarized connectors. Reverse voltage will damage ESC & void warranty.
• Use a female connector on battery packs to avoid reverse shorting.
• Insulate all exposed wiring connection to avoid shorting.
NOTE: If using NiMH/NiCd batteries, the Voltage Cut-Off Circuitry must be
turned OFF (refer to the ESC Track Guide).

STEP 4-one-touch programming
receiver connections
The ESC has a user-replaceable input harness
with the industry-standard connector on both
the ESC and receiver ends of it.
ESC works with all major brand’s new receivers
(very old receivers need wiring sequence changed in
plastic plug on receiver end-- Damage may occur
if sequence is incorrect) . For instructions on
changing the wiring sequences, visit our web site.
1. CONNECT INPUT HARNESS TO RECEIVER HARNESS PINS ON ESC
Insert the 3-pin plug on one end of receiver input harness onto the receiver harness
3-pin header on the ESC. White wire goes on the right side pin as shown above.
2. CONNECT RECEIVER HARNESS TO RECEIVER
Insert 3-pin plug on other end of receiver harness into Ch.2 (throttle) slot of receiver.
3. INSTALL 25mm COOLING FAN ON ESC (OPTIONAL)
Press fan screws through 2 of the holes along one edge of the fan and into the 1st
gap of ESC heat sink fins. Plug fan connector onto ESC’s fan pins--note polarity.
4. CONNECT GLITCH BUSTER CAPACITOR TO RECEIVER
Insert connector of Glitch Buster into any open slot of receiver--note polarity.
This ESC is compatible with standard rate radio systems and also the super-high
speed Airtronics M12 radio system operating in its SSR mode. ESC must first be
switched to the correct radio system mode before it will recognize the receiver and
allow the One-Touch Set-Up programming. ESC ships from Novak in the Standard
Rate Mode and is ready to program if this is what type of system you are using.
For standard rate systems, skip steps A-D below and simply follow Steps 1-8.
If installing ESC with an M12 radio system operating in SSR mode, follow Steps A-D
below to switch modes (refer to ESC Track Guide for detailed information) , then complete
Steps 1-8 afterwards. (Steps A-D need only be done the 1st time)
With at least 2 of the Motor power wires disconnected & the ESC connected
to a charged battery pack, the receiver, & the motor’s sensor harness:
A. TURN ON THE SPEED CONTROL’S POWER
B. PRESS & HOLD ESC’S SET BUTTON until Red & Green status LEDs come on
You must continue holding button until you pass through all of the ESC’s
programming options. Release SET button once Red & Green status LEDs are lit.
C. SELECT PROPER RADIO SYSTEM MODE (2 LED flashes = Std / 1 flash = SSR)
Quick press & release the ESC’s SET button to change the selection.
D. PRESS & HOLD ESC’S SET BUTTON TO STORE NEW SELECTION
1. WITH ESC OFF, TURN ON THE TRANSMITTER’S POWER
2. PRESS & HOLD ESC’S ONE-TOUCH/SET BUTTON
3. TURN ON THE SPEED CONTROL’S POWER
With transmitter at neutral (still pressing SET button), slide ESC’s switch to ON position.
4. CONTINUE HOLDING SET BUTTON UNTIL RED LED COMES ON
5. RELEASE SET BUTTON AS SOON AS RED LED TURNS ON
6. PULL TRANSMITTER THROTTLE TO FULL-ON POSITION
Hold it there until green status LED turns solid green. (Motor won’t run during programming).
7. PUSH TRANSMITTER THROTTLE TO FULL-BRAKE/REVERSE
Hold it there until the green status LED blinks green.
8. RETURN TRANSMITTER THROTTLE TO NEUTRAL
Red status LED will turn on solid, indicating ESC is at neutral and programming is
complete. White LED will also be on & blinking, indicating there is NO Timing Advance (0%).
If transmitter settings are changed, One-Touch Set-Up must be repeated.
Transmitter adjustments are not usually required to properly complete the programming
of the One-Touch set-up. If you are unable to successfully program the One-Touch set-up,
adjust your transmitter settings as listed in the “Transmitter Adjustments” section on the
GTB 3 Track Guide, then repeat the One-Touch Programming steps above.
NOTE: ESC will revert back to factory-default settings
when the One-Touch set-up is performed.
