Waterproof Component
Your new Spektrum®70A Brushed Waterproof ESC has been
designed and built to allow you to operate the product in many
“wet conditions,” including puddles, creeks, wet grass, snow and
even rain.
While waterproof, this component has not been designed to be
immersed in water for long periods of time and should NOT be
treated like a submarine. In addition, most metal parts, including
any screws and nuts, as well as the contacts in the electrical
cables, will be susceptible to corrosion if additional maintenance is
not performed after running in wet conditions.
To maximize the long-term performance of your ESC and to
keep the warranty intact, it should only be used as described
in the “Usage Conditions” section of this manual. Additionally,
the procedures described in the “Wet Conditions Maintenance”
section must be performed regularly if you choose to run in wet
conditions. If you are not willing to perform the additional care and
maintenance required, then you should not operate your vehicle in
those conditions.

5
CAUTION: Failure to exercise caution while using this
product and comply with the following precautions
could result in product malfunction and/or void the warranty.
GENERAL PRECAUTIONS
• Read through the wet conditions maintenance procedures and
make sure that you have all the tools you will need to properly
maintain your ESC.
• Do not operate your ESC where it could come in contact
with salt water (ocean water or water on salt-covered roads),
contaminated or polluted water. Salt water is very conductive
and highly corrosive, so use caution.
USAGE CONDITIONS
Your ESC will operate successfully in any of the following,
individual-usage scenarios:
• 2 hours continuous operation in damp grass or vegetation.
• 2 hours continuous operation in heavy fog (95% humidity,
saturated air, condensing water).
• 1 hour continuous operation in light rain (<0.10 in/2.5mm
per hour).
• 15 minutes continuous operation in heavy rain (>0.30
in/7.6mm per hour).
• 1 hour continuous operation in light sleet (<0.10 in/2.5mm
per hour).
• 1 hour continuous operation in light snow (<0.25 in/6.35mm
per hour).
• 45 minutes continuous operation in standing or running fresh
water (the water level should always remain below the vehicle
frame), or constant splashing water, without any immersion of
waterproof component(s).
• 5 minutes continuous operation in standing or running fresh
water (the water level should never rise higher than 0.5 in
(about 10mm) above the vehicle frame), constant splash-

6
ing water, or frequent, intermittent immersion of waterproof
component(s).
• 1 hour continuous operation in damp sand, dirt, mud or snow
(the material level should always be below the vehicle frame),
constant splatter without any immersion or coverage of water-
proof component(s).
Furthermore, when appropriate maintenance procedures (as
described below) are performed promptly following exposure,
the ESC will remain best protected from corrosion or other
long-term, water-related damage.
WET CONDITIONS MAINTENANCE
• Gently rinse the mud and dirt off the ESC with a garden hose.
• Remove the battery pack(s) and dry the contacts.
• If you have an air compressor or a can of compressed air
available, blow off the ESC to help remove any water that
may have gotten into small crevices or corners. Dry any
water that may be inside a recessed connector housing.
• Let the ESC air dry before you store it. Water may continue
to seep or evaporate out of tight areas for a few hours.
NOTICE: This ESC is waterproofed for use in wet conditions.
Make sure the other components in your vehicle are waterproof
or water-resistant before driving in wet conditions.

NOTICE: Always disconnect the battery from the ESC when
you have finished operating your vehicle. If you leave the
battery connected with the power switch in the OFF position,
the ESC will continue to draw current when connected to the
battery, resulting in possible damage to the battery through
over-discharge.
NOTICE: Do not connect a dedicated receiver battery to the
servo or programming ports. When the ESC/Receiver is turned
On it will provide the servo ports with 6V regulated power from
the main battery. If a dedicated receiver battery is connected to
the servo ports, the ESC/receiver may be damaged.

Installation
1. Determine how to mount the ESC as specified by your vehicle’s
instruction manual, or in an area with adequate airflow and
protection from damage. Ensure all wiring connections can be
reached prior to mounting.
2. Use double-sided foam tape or the mounting tabs with screws
on the bottom of the case to secure the ESC in position. The
switch can be mounted with double sided foam tape.
3. Connect the red power connectors together and the black
power connectors together between the ESC and the motor.
4. If you need to reverse the motor direction you can reverse the
power connections between the motor and ESC.

ESC and Transmitter Calibration
When using a new ESC it is important to calibrate it so the ESC
matches the throttle range on your transmitter. If you install a new
radio system, or make changes to the throttle/brake values in your
transmitter, you must redo the ESC Calibration Process. Failure to
calibrate the ESC to your radio system will result in the ESC not
working correctly. Set the Fail Safe on your radio to a neutral posi-
tion to ensure the motor stops in the event of a signal loss.
1. Power ON the transmitter, and begin with throttle values at
100% for dual rates and travel and at neutral for trim and
sub-trim.
Verify there are no ABS braking functions activated before
proceeding with calibration.
For transmitters without an LCD, turn the D/R knob to the max
setting, and center the throttle trim.
2. Connect a battery to the ESC.

11
Operation
1. Power on the transmitter.
2. Power on the receiver.
3. Disconnect the battery from the ESC after operation.
3. Press and hold the programming button on the switch case,
power on the ESC.
The red LED on the ESC will flash, and the motor will beep.
Release the programming button.
The ESC will enter the programming mode if the programming
button is not released within 3 seconds.
4. With the throttle trigger and trim in the neutral position, press
and release the programming button. The red LED will flash
once, and the motor will emit 1 tone.
5. Pull the throttle trigger to full throttle. Press and release the
programming button. The red LED will flash twice, and the
motor will emit 2 tones.
6. Push the throttle trigger to full reverse. Press and release the
programming button. The red LED will flash 3 times, and the
motor will emit 3 tones.
7. Power OFF the system with the ON/OFF switch.
8. Power ON the system with the ON/OFF switch. The system is
ready for operation
TIP: Beeps from the motor may be quiet and difficult to hear,
use the LED status to help verify settings.
