Place power distribution board
The power distribution board (PDB) allocates power to your copter's motors. Place the PDB
in the center of your copter through the hole in the top plate. Align the PDB so the four 8 mm
spacers insert into the four holes in the PDB. Secure with four nylon nuts.

Solder connectors to electronic speed controllers
Electronic speed controllers (ESCs) regulate how much power is applied to each motor. To
connect the four ESCs to the PDB, you will need to solder the provided Deans connectors to
the ESCs' black and red wires.
Solder Deans connectors to ESCs:
Add a half-inch length of heat shrink tubing onto
each ESC red wire and black wire. Solder the
positive Deans connector plug to the red wire
and the negative Deans connector plug to the
black wire. Shrink tubing over connections.

Connect ESCs to motors and PDB
Connect motor cable bullet connectors to ESC bullet connectors.
Each ESC should connect to only one motor.
The diagram below indicates the number of each motor. Starting
with the motor labeled
corresponding position on the PDB pins (M1 for motor 1, M4 for
motor 4, etc) with the orange wire positioned farthest from the
adjacent Deans connector. Connect ESC Deans connector to PDB
Deans connector for that motor. Repeat for all motors and ESCs.

Don't secure the ESCs to the frame until you have confirmed that each motor spins
in the direction specified in the diagram above (see motor setup instructions at
