1. Introduction
New from R1 Motor lab is the LCG Digital-3 2S/1S Wireless* programmable brushless speed controller. Developed using
the most advanced MICROCHIP processor and a robust proprietary software, the LCG Digital-3 delivers the most
technologically advanced features to date. Development of the LCG Digital-3 was focused on ultra smooth power delivery
needed for modified racing as well as supreme power efficiency for our class leading line of Stock Motors. The controller
offers the most advanced throttle and brake features to suit a wide range of driving styles. The unit features an A.C.L.C.
(Advanced Component Level Cooling) system. This design allows individual encapsulated low resistance Mosfets (inner &
outer components) to transfer heat directly to the upper heatsink. The system also comes equipped with an all new
blinky mode (zero timing) for spec racing, using an advanced commutation algorithm called COOL POWER to keep the
motor cool and deliver powerful, yet ultra smooth acceleration. The LCG Digital-3 boasts a redesigned case minimizing
overall weight and lowering the center of gravity (LCG). We have minimized the weight from the upper case while
improving heat dissipation, achieved by improving air velocity exits from all sides of the ESC case. All adjustable settings
are easily programmed using the R1 WIRELESS ADAPTOR coupled with an iOS or Android app designed with an intuitive,
easy to use interface. The new R1 Digital 3 app also features a super fast Live Telemetry and a built in Datalogger for
after race analysis. Built in Amp draw meter for setting motor timng or race analysis. Using our new over the air updates
feature, firmware updates are now easily downloaded through our iOS or Android apps.
2. Caution
Avoid short circuits: make sure all ESC wires and connections are protected and are not in contact with peripheral
devices.

4. Connection
Caution
For maximum performance, the black silicon wire without any connector is 12AWG. For soldering the battery and
motor wires onto the solder bar, set the iron to a minimum of 60W. Avoid soldering more than 5 seconds or the ESC
may overheat and become damaged. Use the provided tube casing to prevent the short circuit and to check the
polarity after connection.
Motor Wire Connection
When connecting ESC and motor, the wire A/B/C should be inserted in their respective places. However, some cars are
wired backwards. In this case, switch the Motor-Wiring setting from A-B-C to C-B-A. The C and A wires will be
reversed from how they are shown on the figure above: incorrect setting and connection can cause critical problems.
Keep in mind that if the ESC is reset, then the C-B-A wiring setting will default back to A-B-C; change it to C-B-A
again before use.
After connecting the A/B/C wires, connect the sensor wire to the 6-pin sensor port.
Power Capacitor
Never drive without the power capacitor! This is necessary to protect the ESC and improve performance. Pay
attention to polarity: incorrect connection and poor soldering will damage the ESC. (The power capacitor is not
covered by the warranty.)
As shown in the figure above, connect the indicated red wire to positive (+) ESC post. Connect the short wire to
negative (-) ESC post.

4
Battery Wire Connection
When connecting the battery, pay attention to polarity: incorrect connection will damage the ESC. (The battery is not
covered by the warranty.)
As shown in the figure above, connect the positive (+) wire is connected to (+) battery port, and the negative (-) wire
is connected to the (-) battery port.
Receiver Wire Connection
Before connecting the ESC to the receiver, the transmitter should be in default settings. See Transmitter Settings.
Connect the ESC throttle wire to the receiver CH2. The signal wire has a white indicator. The signal wire supplies
6-7.4V to the receiver, servo, etc., so there is no need to connect an additional battery. External power connected to
the receiver may damage the ESC.
Fan Connector
A cooling fan, screws and fan protector are provided per the ESC specification. It is recommended using the fan under
the extreme situations, such as modified or 4WD off-road. The fan will not operate if the ESC temperature is at or
below 95°F (35°C) or if the motor RPM is low.
Connect the fan using 2-pin connector at the front of the ESC. Mount the fan to the top of the heat sink.
5. Connection Install Guide
Place the ESC in a safe place where is easily accessible to connector and buttons.
Leave enough distance between the ESC, power wire and antenna/receiver to avoid the parts directly touching.
Receivers and antennas placed too close together may result in signal confusion. Parts must be re-install at a
further distance apart.
Tightly affix the ESC with double-sided tape (included).
6. Transmitter Settings
Before connecting the ESC to the receiver, the transmitter should be in default settings, as shown in below:
Disconnect the ESC from the battery. Turn the ESC power switch OFF.
Remove the motor pinion, or lift the car off the ground and verify the wheels rotate freely.
Turn the transmitter ON and place the throttle in NEUTRAL.

Error History
M,T1,T2, S, V, R
Motor Type
Sensor: The Sensor Mode is the recommended and default mode because it provides the power system with the
highest efficiency and racing performance. If a sensor error occurs during operation, the transmission operates in the
sensorless mode immediately; check the motor and sensor cable connections.
Hybrid: In Hybrid Mode, after the ESC is switched ON it works with a sensored motor at low RPM. Conversely, upon
being switched ON the ESC automatically works with a sensorless motor. This mode could be used for 4WD SCT of 4
pole motors.
Select Battery
Select the correct battery type. Incorrectly selecting the battery type can irreparably damage the battery.
Cut Off Voltage
Set the minimum voltage at which the battery will run. This function automatically cuts-off the battery to protect it
from excessive discharging, which causes irreparable damage.
Power Curve
ESC output is effected by the throttle curve parameters in relation to the throttle position. Default setting is “5”; the
power curve should be changed into other shapes using a PC program or WiFi module. For example, if +EXP value is
added at the beginning of the curve, the value of the initial output is increased, conversely, if –EXP value is added,
smaller throttle value is output.
Boost Max+TB
OFF: All timing is disabled. The LED should blink GREEN at neutral in this mode. This is the preferred mode for
Stock Racing.
ON: The speed and efficiency of the motor is depending on boost timing setting. When boost timing is bigger, speed
should be fast, and it also impacts the output depending on the motor RPM. Higher values would increase the power

8
and RPM but also cause high heating. So, excessive setting could cause fatal problems to the ESC and motor.
TB (TURBO): should be activated when the throttle is located at 100%. (Boost setting + TB setting) are applied into
timing. Although the combined value of the two can be set up to 116, its upper limit is 88. If the motor timing is set
to more than 60 from the center, it can cause heating in the motor and ESC. It is recommended to set to 60 or lower.
This item is an ideal for long straight course. In Hybrid Mode, the maximum value of both settings is limited to 25.
ATH(Auto Throttle)
If the Auto Throttle function is set, the Boost does not get affected by RPM, but operates only according to the
throttle ratio. For example, if the set value for the Boost is 30 and the throttle position is 40%, the operating boost
outputs “12”which is 40% of 30.
Boost-TH. Limit
At Boost Mode, +TH mode allows the setting of timing limit with 10 steps of the throttle location. Please refer to the
graphs below.
Boost Min-rpm
Set the minimum RPM that will activate the Boost timing. For example, with a minimum set to 1000 RPM, the boost
timing will be activated as soon as the RPM reaches 1000. This option can be set between 0~64500 but cannot be
higher than the Boost Max RPM.
Boost Max-rpm
Set the maximum RPM limit for the boost timing. For example, with a boost value set to 20-degrees and maximum
RPM set at 20000, the boost will cap out and hold at 20-degrees once the ESC crests 20000. This option can be set
between 0~65000 but cannot be lower than the Boost Min RPM.
Turbo Delay
Delay the turbo activation. Turbo is immediately activated when the delay value is set as “0.00” and the throttle is
moved to “full”. When a value is entered, the turbo is only activated after the throttle is moved to full and the set
delay time has elapsed.
Turbo + Slope
Set the amount of time it takes to reach turbo speeds after activation. The lower the value, the more the acceleration

and heating is increased.
Turbo –Slope
Set the amount of time it takes to recover from turbo speeds when the throttle is back to the original location. The
lower the value, the more the brake effect and vehicle movement is decreased.
Acceleration
Set the amount of time it takes to reach maximum output from idle.
Start Power
Set the minimum amount of power to be used to start the motor or when the motor is rotated
Smooth Start Rate
The modified motor has a large output when starting, which hinders a car from moving gently due to the strong
power of its start. This function allows a gentle start with the effect of applying the boost value in “-“direction
according to the set value.
Smooth Start Range
This is to set throttle stick range for smooth start. For example, if it is set to 50%, the smooth start function works up
to 50% of the throttle stick. If one of the Smooth Start Rate and the Smooth Start Range is set to “0”, this function
does not work.
Reverse Function
One Way: forward / brake
Two Way: Forward / brake / reverse. Reverse is activated after reverse delay. Brake is activated during the delay period.
Two Way2: Forward / brake / reverse. Reverse is activated after 1second of motor pause, regardless of the reverse
delay. Direction can be changed after max 6~7 seconds.
Two Way3: Forward / brake / reverse. When the motor is rotated forward, if the throttle stick is moved to the reverse,
the brake is activated. Even if the stick stays there, reverse function is not activated. To activate reverse, move the
throttle stick to the neutral position and back to the reverse direction again.
Reverse Delay
Set the delay time between when the function is triggered and the reverse is activated.
M- Reverse Amount
Set the max reverse speed during driving between 20~100%.
Neutral Width
Set the neutral width. The neutral width is the area around transmitter’s neutral position.
Motor Direction
Set the forward / reverse rotation of the motor.
Brake Response
Adjust the break strength. The higher the percent, the stronger the brake.

10
FAN Control
In the Auto mode, it works depending on the ESC temperature and throttle position. In the On mode, it works all the
time.
Drag Brake
Set the auto brake function to deliver a small brake effect at neutral position.
Min Brake Amount
Set the minimum percent of the brake range.
Mid Brake Amount
Set the middle percentage of the break range.
Mid Brake Location
Set the position of the middle brake range.
This function is deactivated when mid brake amount and mid brake location are set at 0%.
Max Brake Amount
Set maximum percent of the brake range. Always leave the brake at the “FULL BRAKE”position.
Soft Brake
This is to set the brake power like “Hard”or “Soft”. It is recommended to use “Hard”brake when using Stock Motor.
Brake Freq
This is to set the brake frequency. When the frequency is lower, control becomes also bigger, and if the frequency is
higher, soft control is achieved.
Motor Freq
Set the motor frequency. The lower the frequency, the faster the initial acceleration; the higher the frequency, the
softer the acceleration and more heat is generated by the ESC.
Note: Hybrid Mode only supports 8khz and 16khz.
Drag Freq
Set the drag frequency. The lower the frequency the better the effect of the break control; the higher the frequency
the softer the break control becomes.
Cut Off Temp
Set the ESC cutoff temperature. The ESC will cutoff when reaching the set temperature. Disabling this function is not
recommended, as the ESC will not be temperature-protected and may become irreparably damaged.
Cut Off M-Temp
Set the motor cutoff temperature. The motor will cutoff when reaching the set temperature. Disabling this function is
not recommended, as the motor will not be temperature-protected and may become irreparably damaged.

11
B.E.C Voltage
Set the voltage supplied to the receiver. Refer to the servo specifications for accurate voltage values, as the ESC may
become irreparably damaged.
7.4V does not work when using a 1S battery.
Motor Pole Num
Set the motor poles. Incorrect pole setting could result in inaccurate maximum speed readings.
Gear Ratio
Set the vehicle gear rate. Incorrect gear ration setting could result in inaccurate maximum speed readings.
Tire Diameter
Set the tire diameter. Incorrect tire diameter setting could result in inaccurate maximum speed readings.
Motor-Wiring
Set the motor cable connection: A-B-C or C-B-A. Make sure the wire configuration and Motor-Wiring setting match,
as the ESC could become irreparably damaged.
