Important Hints and Tips Reference

Warning

When powered on, the motors and propellers will rotate very

quickly and can cause serious damage or injuries. Always be

vigilant and make safety your top priority.

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. Ensure that there are no open circuits or short circuits when

soldering the ESC cables.

4. Before takeoff, ensure that the propellers and motors are

installed correctly.

5. Ensure that all parts of the aircraft are in good condition. DO

NOT y with worn or damaged parts.

Introduction

The Snail Racing Propulsion System is a multirotor propulsion

system designed for racing multirotor aircraft with a max thrust

of 1.32kg/rotor. Based on the operation environment of racing

multirotor aircraft, impact analysis and drop tests are performed

on the Snail 2305 Racing Motor to guarantee its rugged

structure.

The Snail 430-R Racing ESC uses a 32 bit motor driver chip with

a maximum main frequency of 100MHz. Its advanced algorithms

allow a responsive motor drive with precise control and its small

power supply ripple ensures normal performance of other power

supply units when motors reach maximum current output. Like

most DJI products, the ESC rmware can be updated, ensuring

that the Snail is constantly rened.

Features

Active Braking Function

3D Mode*

Two Throttle Signal Modes

Regular throttle signal: 30Hz to 500Hz PWM signal

OneShot125 signal: 30Hz to 1000Hz

High Rotational Speed Motors

46,000rpm (7 pole pairs)

322,000rpm (1 pole pair)

6. Only use compatible, authorized DJI parts.

7. Ensure that all parts are rmly in place and all screws are tight

before each ight.

8. 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.

9. 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.

10. Ensure that the motors rotate smoothly before takeo.

Active Braking Function: The motor actively reverses torque

when decelerating, recovering some of the rotational energy.

Normal braking relies mainly on air resistance.

Assistant 2 to activate the 3D mode of the 430-R Racing ESC

(Refer to Connecting the ESCs for more information).

In the Box

A DJI Snail Propeller Adaptor is required for mounting 6048-

3D Propellers and 5048 Tri-Blade Propellers on the motors.

5048S Tri-Blade Quick-Release Propellers are recommended

for use with the Snail Racing Propulsion System. Y-shaped

and aerodynamic designed blades enable them to provide

racing multirotor aircraft with sufcient strength and stiffness.

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 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.

Be sure to solder the cables onto the pads according to

the specications 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.

VCC Cable (White), GND Cable (Black)

Ensure that there are no open circuits or short circuits

when soldering the ESC cables.

Propeller Adapter, spring and screws

Use a suitable Propeller Adapter and airframe that can

withstand the large thrust delivered by the Snail Racing

Propulsion System.

Choose an appropriate screw length and screw size

according to the depth of the assembly hole and thickness of

the motor mounting plate. Using screws that are too long or

too large may not be able to secure the motor.

When mounting or removing the motors, be careful to prevent

foreign articles from entering the motors.

Assembling the Propellers

Quick-Release Propellers

This example uses the 5048S propellers. Instructions also apply

to the installation of 5024S, 6030S and 7027S.

1. Pair the propellers marked CW with the clockwise rotating

motors; pair the unmarked propellers (white ring on the

Other Propellers

This example uses the 6048-3D propellers. Instructions also

apply to the installation of 5048 Tri-Blade Propellers.

Tools Required: M2 hex key and Snail Propeller Adapter.

1. Remove the screws securing the Quick-Release Propeller

Adapter on the 2305 Racing Motors, and then remove the

Quick-Release Propeller Adapter.

bottom of the propellers) with the counterclockwise rotating

motors (with white dots).

2. Align gap A inside the propeller nut with n B on the Propeller

Adapter. Press the propeller down onto the adapter rmly and,

while holding the propeller pressed down, rotate the propeller

in the lock direction (propellers marked CW rotate counter-

clockwise; propellers without markings rotate clockwise) until

you feel it secure in place.

3. To remove the propeller, press the propeller down rmly and,

while holding the propeller pressed down, rotate the propeller

in the unlock direction until it can be removed easily.

2. Remove the cap on the Snail Propeller Adapter.

3. Align the holes of the black Propeller Adapter with the holes

on the CW motors. Insert the M2×4 screws and tighten to

secure. Align the holes of the red Propeller Adapter with

the holes on the CCW motors. Insert the M2×4 screws and

tighten to secure.

Stand clear of the motors and DO NOT touch the propellers

when they are spinning.

Use only DJI approved propellers.

Use appropriate propellers for your needs, as they can wear out.

Pay attention to screws properly during installation and removal.

Before mounting 6048-3D Propellers, select 3D Mode in DJI

Assistant 2 and update the corresponding rmware. (Refer to

Using DJI Assistant 2 for details)

Using DJI Assistant 2

DJI Assistant 2 is used to update and configure the ESC.

Remove propellers before connecting to DJI Assistant 2.

430-R ESC ESC Programmer

Unplug any other serial devices connected to your PC before

updating. Then follow the instructions below.

1. Download and install DJI Assistant 2 from the Official DJI

website. (http://www.dji.com/snail/info#downloads)

2. Connect the ESC Programmer to the ESC with the PWM

signal cable and to your computer using the USB cable on the

programmer.

3. Connect a battery (3-4S LiPo) to supply power to the ESC.

Do not disconnect the ESC from your computer or the power

supply until conguration is complete.

4. Install the unmarked propellers onto the red Propeller Adapter,

and install the propellers marked with CW onto the black

Propeller Adapter.

5. Secure the propellers by rotating the red cap onto the axes of

the red Propeller Adapter and black cap onto the axes of the

black Propeller Adapter.
