selecting brushless profiles :
all LEDs
With ESC on & connected to a charged battery (transmitter ON or OFF) :
1. IF TRANSMITTER IS OFF, DISCONNECT ESC FROM RECEIVER
To avoid possible radio interference, remove the ESC’s input signal harness
from the receiver--Green LED will stay on to indicate no signal from receiver.
2. PRESS & HOLD THE ESC’S ONE-TOUCH SET BUTTON
Continue to hold SET button on ESC until all 4 LEDs turns on.
Note: You will continue holding past all the LED programming indicators in
the ESC’s software as shown in the flow chart on back side of this sheet.
3. RELEASE SET BUTTON AS SOON AS ALL 4 LEDs COMES ON
Once released, the 4 status LEDs will flash to indicate what Throttle Profile is
currently selected. The number of times the LEDs flash indicates the Brushless
Throttle Profile selection (1 of 3).
4. QUICK PRESS (& release) SET BUTTON TO CHANGE SELECTION
Each press will change to the next consecutive Throttle Profile. (After Profile
3 in Brushless-Mode, the sequence begins again at Profile 1)
Note: there is a time constraint during this selection process.
5. ESC STORES SELECTION & BEGINS TO EXIT PROGRAMMING
If SET button is not pressed for 3 seconds, ESC stores selected Profile in
memory, exits to neutral & is ready to go. (LEDs turn off in a rolling motion
left to right, then Red LED turns on solid-- Green LED will be on if no transmitter
signal present & Blue or Blue & Amber LEDs on if Drag or Min. Brakes above 0%) .
Note: ESC reverts to factory default settings & Throttle Profile #1 whenever One-Touch set-up is
performed (reverts to Profile #4 Brush-Mode if no brushless motor sensor harness is connected).

Motor operating temperature is the
proper way to set the vehicle gearing
The motor should not exceed 170°F at end of run!
Change the gearing to avoid overheating.
If you do not change gearing after switching to brushless, you may be
over-geared and have slow acceleration & excessive temperatures!
With the extremely broad power band of the Novak Crawler brushless
motors, you can gear your vehicle for more top speed (without going
to a higher voltage battery pack), but remember gearing higher will
produce more speed control & motor heating. Always check the motor’s
operating temperature after making any gearing adjustments--motors
are designed to operate safely up to 160-170ºF.
proFile adjustments
The following parameters are adjustable in the ESC’s software:
DRAG BRAKE (1 of 10 settings from 1.5 to 13.5% in Brushless Profiles, & 1 of
10 settings from 10 to 90% in Brush-Mode) --The amount of braking applied
while the transmitter is at neutral. Also known as ‘hill’ or ‘auto’ brakes.
Raising this setting makes the motor slow down more without
pushing the transmitter’s trigger into the brake/reverse direction.
This adjustment is not available in the Servo/Robotic Profile #3.
DEAD BAND (1 of 5 settings from 3 to 9%)--The space between Minimum
Brake and Minimum Drive, with neutral in the middle.
Raising this setting will increase the ‘free play’, or distance your
trigger must move before forward drive or braking will begin.
MINIMUM DRIVE (1 of 5 settings from 2 to 12%)--The amount of forward
drive applied with the first pulse of transmitter throttle information.
Raising this setting makes the motor start at a stronger/higher
level so it takes off more aggressively from neutral.
DRIVE FREQUENCY -Brush-Mode Only-(1 of 7 settings from 3.5 to 15kHz) --The
frequency at which the duty cycle information is being sent from the
speed control to the motor to control the speed.
Raising this setting makes the control of the motor feel more smooth.
Normally this value would be lowered for use with higher turn motors
to get more ‘punch’, and it would be raised for hotter, low-turn motors
or slippery track conditions for more control of the power delivery.
Li-PO cUt-OFF circUitrY
When active (see programming on reverse side to turn ON/OFF), the built-in
Novak Smart-Stop Li-Po Cut-Off Circuitry lets you safely use 2S Lithium
Polymer battery packs by cutting off the speed control’s throttle output
when a critical safety voltage is reached.
The circuitry constantly monitors the pack voltage. When it gets close to
the critical safety voltage (6.25V) it begins interrupting, or ‘blipping’ the
throttle output as an early warning that the battery’s voltage is getting
low and the throttle output will soon be completely shut off.
When the critical voltage is reached, the throttle output to the motor
gets completely shut down to keep the voltage from dropping further
(Red & Green LEDs will alternately flash & you still have steering control).
Re-charge battery after Smart-Stop circuitry shuts off throttle
Even though the pack’s voltage will rise (after a short resting period) to a level
high enough to run motor again, this is not good for Li-Po batteries.
Reaching critical safety voltage too many times can damage the cells.
DO NOT CONTINUE TO RUN VEHICLE AFTER THE SMART-STOP HAS SHUT
DOWN THE THROTTLE OUTPUT THE FIRST TIME.
During power-up when the ESC is switched ON, the Amber & Red
LEDs will flash together 3 times to indicate Li-Po Cut-Off is ACTIVE.
With the Li-Po Cut-Off turned ON & using Ni-Cd or Ni-MH cells, the circuitry will shut off the
ESC’s throttle output very early into the run, due to the different characteristics of these batteries.
mOtOr rOtAtiON SeleCtiOn
The Goat’s software lets you reverse the brushless motor’s rotation direc-
tion. This allows installation in vehicles with counter-rotating drive trains
(or opposed transmissions) , without compromising performance.

expo throttle curve
Profile #2 in the Goat ESC’s software features an exponential throttle
curve in both the forward and reverse directions. This provides you
with extremely smooth throttle response for the precision movements
required in the most demanding technical rock crawling courses.
progressive ramP-uP braking
The Goat ESC’s braking use battery power to slow the motor, and can
supply amazing amounts of braking. In Brushless Profiles 1 & 2, the brakes
linearly ramp up to the value of Drag/Hill brakes that you program. This
provides smooth application of braking without risk of roll-overs.

to custom program profiles:
Your transmitter can be either ON or OFF:
1. IF TRANSMITTER IS OFF, DISCONNECT ESC FROM RECEIVER
Remove input signal harness from receiver to avoid radio interference.
2. CONNECT SPEED CONTROL TO A CHARGED BATTERY PACK
3. SLIDE ESC’s ON/OFF SWITCH TO ‘ON’ POSITION
4. MAKE SURE THE THROTTLE PROFILE TO ADJUST IS ACTIVE
If you are not sure what profile is selected, follow the procedures in ‘Throttle Profile
Selection’ to check or select the desired profile.
5. FOLLOW STEPS ON RIGHT SIDE OF THIS PAGE TO CUSTOMIZE ESC
You can adjust different parameters (described on back side of this sheet) to fine tune the
speed control to perform & feel the way you like it.
Remember that you can not access the Brush-Mode (Profile #4) without
disconnecting the brushless motor’s sensor harness from the ESC.
Note: there is no time constraint during selection process of custom parameters.
