Warning
1. Always attempt to y your aircraft in areas free
of people, animals, power lines, and other
obstacles.
2. DO NOT approach or touch the motors or
propellers when the unit is powered on.
3. Before takeoff, ensure that the propellers and
motors are installed correctly.
4. Ensure that there are no open circuits or short
circuits when soldering the ESC cables.
5. Ensure that all parts of the aircraft are in good
condition. DO NOT y with worn or damaged parts.
6. Ensure that all parts are rmly in place and all
screws are tight before each ight.

7. The input throttle signal mode (regular or
OneShot125) cannot be changed while the
product is in use. Set the input throttle signal mode
on your ight controller. Restart the electronic
speed controller to apply the new mode.
8. DO NOT connect the electronic speed controller
to a DC regulated power supply, or the power
system and the electronic speed controller will
be damaged when the product captures energy
produced during deceleration as this product has
Active Braking Function by default.
9. Be sure to use the product in strict accordance
with the specications (voltage, current,
temperature, etc.) listed in this document. Failure
to do so may result in permanent damage to the
product.
Introduction
The Snail 430-R Racing ESC is designed for racing
multirotor aircraft, using a 32 bit motor driver chip with
a maximum main frequency of 100MHz. Its advanced
algorithms give it a responsive motor drive with precise

5
EN
control and a small power supply ripple that ensures
normal performance of other power supply units when
motors reach their maximum current output. Like most
DJI products, the ESC firmware can be updated,
ensuring that the Snail is constantly rened.

Connecting the ESCs
Tool Required: Power distribution board (PDB),
electric soldering iron and soldering tin.
1. Solder the ESC’s black GND cable and white VCC
cable to the pads on the PDB as shown.
2. Connect the signal cable to your ight controller.
The signal cable’s white wire transmits the control
signal; the black wire is for GND.
3. Connect the motor to the ESC. Test the motors and
ensure that the rotation direction of each motor is

7
EN
correct. You can reverse the rotation direction by
swapping the positions of any two cables. See
below the ESC Conguration for more information
on how to reverse the motor rotation direction.
4. A PMW signal cable is also used to connect PC to
update rmware.
PWM Signal Cable (To ight controller)
VCC Cable (White), GND Cable (Black)
Be sure to solder the cables onto the pads according
to the specifications of your PDB. The PDB in the
gure uses its outer pads for the black GND cables,
and the inner pads for the white VCC cables. Cut the
cables to length. The cables should be shortened to
avoid bunching up near the solder points. As shown in
the picture.

Ensure that there are no open circuits or short
circuits when soldering the ESC cables.
ESC Conguration
Calibrate the throttle range and switch the motor
rotation direction using the remote controller.
1. Power on the remote controller and receiver. Ensure
a strong link between them. Push the throttle stick
all the way up. The motor will start a double beep, a
single beep sequence.
2. Then the warning sound will alternate between a
quick single beep and a quick double beep. Pull
the throttle stick all the way down after hearing a
single beep to calibrate the throttle. Pull the throttle
stick all the way down after hearing a double beep
to reverse the motor rotation direction. By rotating
the desired motor quickly in any direction, this
motor’s rotation direction will be changed.
3. The warning sound becomes a chime when
completed.
4. Restart the ESC after reversing its rotation direction.
