No part of this product or document shall be reproduced in any form without the prior written consent or authorization of DJI. EN 3

4 EN This disclaimer is produced in various languages. In the event of divergence among different versions, the Chinese version shall prevail when the product in question is purchased in China, and the English version shall prevail when the product in question is purchased in any other region. Warning 1. Always attempt to fly 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 fly with worn or damaged parts. 6. Ensure that all parts are firmly in place and all screws are tight before each flight. 4

5 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 flight 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 specifications (voltage, current, temperature, etc.) listed in this document. Failure to do so may result in permanent damage to the product. EN 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

6 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 refined. Features Active Braking Function 3D Mode* Two Throttle Signal Modes Regular throttle signal: 30Hz to 500 Hz PWM signal OneShot125 signal: 30 Hz to 1000 Hz High Rotational Speed Motors 46,000 rpm (7 pole pairs) 322,000 rpm (1 pole pair) Maximum Continuous Current: 30A DJI Assistant 2 Software Complete Electromagnetic Compatibility Test Radiated emission Electrostatic discharge immunity Radiated RF electromagnetic field immunity Typical Applications: Racing multirotor aircraft 6

7 * Get D Propellers and update the ESC firmware via DJI Assistant 2 to activate the 3D mode of the 430-R Racing ESC. EN In the Box 430-R Racing ESC 1 Heat-shrink 1 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 flight 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 7

8 EN ensure that the rotation direction of each motor is correct. You can reverse the rotation direction by swapping the positions of any two cables. See below the ESC Configuration for more information on how to reverse the motor rotation direction. 4. A PMW signal cable is also used to connect PC to update firmware. PWM Signal Cable (To flight 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 figure 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. 8

9 Ensure that there are no open circuits or short circuits when soldering the ESC cables. EN ESC Configuration 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. 9

10 EN System Status Beep Codes The motors will beep when the Snail is in use. The table below contains more information about the warning sound. Alarm Chime Rapid Beeping Slow Beeping Alternating Single and Double Beeps Description Ready to work Minimum throttle signal not reached. Check the flight controller, remote controller or remote controller receiver. No throttle signal.
