throttle profile selection

The Goat 3S Brushless/Brush Crawler speed control is equipped with 3 user-selectable Throttle Proﬁles, as shown below.

NOTE: The Goat 3S has the ability to run on either two or three-cell Li-Po batteries via Novak’s auto detect software. When Li-Po circuitry is active (see programming on reverse side to turn ON/OFF), it automatically switches to the proper Li-Po cut-off voltage for the battery packs you connect.

proFile adjustments

The following parameters are adjustable in the ESC’s software:

DRAG BRAKE

10 settings from 10 to 90% in Brush-Mode)

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.

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/reverse 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

DRIVE FREQUENCY

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.

MOTOR ROTATION SELECTION (adjustable in Brushless Mode) --

3S’s software lets you reverse the brushless motor’s rotation direction. This allows installation in vehicles with counter-rotating drive trains (or

opposed transmissions), without compromising

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.

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 2).

QUICK PRESS

Each press will change to the next consecutive Throttle Proﬁle. (After Proﬁle

2 in Brushless-Mode, the sequence begins again at Proﬁle 1)

Note: there is a time constraint during this selection process.

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-signal present & Blue or Blue & Amber LEDs on if Drag or Min. Brakes above 0%)

Note: ESC reverts to factory default settings & Throttle Proﬁle #2 whenever One-Touch set-up is performed (reverts to Proﬁle #3 Brush-Mode if no brushless motor sensor harness is connected).

proper gear selection

Motor operating temperature is the

proper way to set the vehicle gearing

The motor should not exceed 160°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 160ºF.

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 or 3S Lithium Polymer battery packs by cutting off the speed control’s throttle output when the critical safety voltages are reached.

The circuitry constantly monitors the pack voltage. The Goat 3S automatically selects a 2S or 3S Li-Po cut-off voltage value (6.25V for 2S and 9.375V for 3S). When the ESC detects that either critical safety voltage value will soon be reached, 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 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

When the ESC is switched ON, the Amber & Red LEDs will ﬂash

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.

expo throttle curve

The brushless proﬁles in the Goat 3S 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 braking

The Goat 3S ESC’s braking use battery power to slow the motor, and can supply amazing amounts of braking. In Brushless Proﬁle #1, 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.

-- CUSTOM programmiNG

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

speed control to perform & feel the way you like it.

Remember that you can not access the Brush-Mode

disconnecting the brushless motor’s sensor harness from the ESC.

Note: there is no time constraint during selection process of custom parameters.
