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 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 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.
