3. Connecting the ESCs
Tools Required
Tools:
Power hub, electric soldering iron and soldering tin
Use:
To solder each ESC’s power cable to the power hub
1) Please solder each ESC to the power pads on the power hub as shown in
the figure below. Make sure that the solder is firmly attached to the power
pads and that there is no possibility for a short circuit. The power cable is a
coaxial power cable. Do not damage the protector on the red cable to avoid
short circuits.
2) Connect the signal cable to your controller. The signal cable’s orange wire
is for the control signal, the signal cable’s brown wire is for the GND, and
the red wire is reserved.
3) Connect the motor to the ESC. Test the motor and ensure that the rotation
direction of each motor is correct. If not, switch the position of any two
cables connecting the motor to the ESC to change the rotation direction.

Take the power hub in the figure for example. The outer power pads are for the
GND cables, and the inner power pads are for the power cables. The red core
of the coaxial power cable is positive, and the shielding layer of the coaxial
power cable is negative. Make sure to solder them correctly. Try to solder the
cables firmly to the power hub at the proper length (the wires should be just
long enough to reach the soldering point, face outwards, and should not be
bunched up in front of the soldering point).
Make sure that there are no open circuits or exposed wires that can
cause short circuits.
It is recommended that you solder a power connector onto the power hub.
4. Mounting the Motors
Mount each motor to a frame arm according to the motor dimensions and the
size of the assembly hole.
The screw size is M3. Mount the
motors using the appropriate
screws.
Note the thread depth and the
size of the screws. Using screws
that are too long or too large may
damage the motor.
