The Ultimate Dual Motor Crawling Speed Controller
The M2 Dig 3S Dual Brush ESC has the ability to run on 2S or 3S
Li-Po/Li-Fe batteries and can independently control two brushed motors to
perform dig maneuvers. Proportional Dig Mode allows for variable amounts
of dig power, plus the level of dig power is programmable separately from
the Hill/Drag Brake adjustment.
The M2 Dig is factory-loaded with 3 throttle profiles, Thermal Overload Protection,
high-power BEC, external dig indicator LEDs, and includes everything needed to
operate, including cooling fan and external PowerCap.
This one-of-a-kind speed control requires a three-channel transmitter to operate. Refer
to the Novak Web site for a complete list of compatible transmitters.

Technology, Radio Priority Circuitry, & One-Touch Set-Up are all trademarks of Novak Electronics, Inc. The
M2 Dig’s dual independent motor control design and dig functionality is patent pending and the sole
property of Novak Electronics, Inc.
The included cooling fan is recommended for 3-cell operation.
The M2 Dig ESC features a set of power output pins for running cooling fans,
auxiliary lights, scale winches, etc. This power is regulated to 6.0VDC (same as the
BEC)
, and switches on & off with the ESC’s power switch, so you get maximum
output without over powering by running directly from the battery pack’s voltage.
The M2 Dig’s heat sink is designed to accept a 25x25mm cooling fan, and comes
with nylon 4-40x5/8” screws to secure it. To install, simply center fan on ESC
and push the nylon screws down into the cross cuts of heat sink. If using metal
screws
(M3 or 4-40)
, thread them into the heat sink.
The pin-out label located on the ESC’s
case under the pins & LEDs shows the
polarity of the power output pins,
which are the two pins on the corner
of the ESC. Positive (+) is on the left,
and Negative (–) is on the right.
The two sets of three pins behind the
power output pins are for the input
signal harnesses. The polarity is the same
for both: Positive in the middle, Negative
on the left, and signal on the right.

CONTACT:
When active (see Field Guide to turn ON/OFF), the built-in Novak Smart-Stop Voltage
Cut-Off Circuitry lets you safely use 2S or 3S Lithium Polymer (LiPo) or Lithium Iron
Phosphate (LiFe) 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 and automatically selects a 2S
or 3S cut-off voltage value
[6.25V (2S), 9.75V (3S) Li-Po; 4.75V (2S), 7.125V (3S) Li-Fe]
. When
the ESC detects that the critical safety voltage 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 (after a short resting period) to a level high
enough to run motor again, this is not good for LiPo or LiFe 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.
When the ESC is switched ON, the Yellow & Red LEDs will flash
together 2 or 3 times to indicate LiPo/LiFe Cut-Off is
ACTIVE
.
With the Voltage Cut-Off Circuitry turned ON & using NiCd or NiMH cells, the circuitry will shut
off the ESC’s throttle output very early into the run, due to the different characteristics of these
batteries. Change the ESC’s Voltage Cut-Off Circuitry mode to OFF to use these batteries. See
CUSTOM PROGRAMMING
options on the Track Guide to properly adjust this setting.

control is at neutral and that proper programming has been completed.
NOTE: If transmitter settings are changed, One-Touch Programming must be repeated.
If you experience any problems, turn off ESC and repeat One-Touch.
NOTE: Whenever the One-Touch Programming set-up is performed, the
speed control will automatically revert back to the factory-default settings.
If you are planning to use an external receiver battery pack with the M2 Dig 3S ESC
