1. Solder the Transmitter and Camera

Cut the wires of camera to suitable length and solder them to PDB.
Red wire: Power
Black Wire: GND
Yellow: Signal

Solder the power supply wire and video wire (yellow) of transmitter to PDB.


2. Install OSD

The OSD firmware must be flashed and compatible to the Flight Controller before installation. If you don’t need to install the OSD, please just skip this step.

Solder the pin headers onto PDB.

Install the OSD on PDB. Insert it onto the pin heads and soldered. After secured, cut off the unnecessary length of pins.

3. Install the Buzzer

Pay attention to the positive pole “+” on the buzzer.  It needs to be soldered to the buzzer location on PDB.

Cut off the unnecessary pins.



4. Install ESCs
 
Solder the ESCs onto PDB.


The black wires can be parallel connected to the negative pole “-”.
 
 
5. Install Brushless Motors


The motor’s rotation direction can be changed by changing any two wires.

6. Extension


If the OSD and buzzer are installed, then you’ll need to use the supplied wires to solder onto PDB. Please take notice of wire length.


7. Install Flight Controller

Notice on the flight controller: It doesn’t require for soldering if the ESCs have no BEC. The flight controller can be powered by soldering to “5V” (circled in red).
