Instructions

1/ Start off by building your quadcoper frame, once assembled mount a motor on each arm.


2/ solder the motor wires on to the ESC wires and cable tie the wires to the arm


3/ Add an XT60 connector to the end of the esc and remove the red conductor from the 3 pin connector and isolate.



4/ now you need to make a harness to go from 1 female XT60 connector (that plugs into your battery) out to 4  male XT60 connectors (for the speed controllers)

5/ plug this into your speed controllers and thread the female XT60 through the frame of the quad to the bottom where the battery will mount.

6/ fit your KK board and plug the motors in as shown below

7/ Now connect your RX to the inputs of the quadcopter

8/ If you got your board from Hobbyking then it is flashed to fly + config, you can re flash using the optional programmer to fly x config but be warned there is a bug with the v4.7 firmware that causes motor 4 to have a big deadband in the throttle response so you might want to flash with v2.5 as I did, you can download the firmware from http://www.kkmulticopter.kr/multicopter/firmware/FlyCam_XCopter_v2_5.zip

I would recommend Lazyzero's flash tool available free (you can donate) form http://www.lazyzero.de/en/modellbau/kkmulticopterflashtool

9/ Set your esc throttle range up 

you may have difficulties programming all at once but the procedure should be

9/ a/ Remove props

    b/ Turn on TX and set throttle to max

    c/ Turn YAW adjust to min

    d/ Connect battery to KK board and esc's 

    e/ ESC's will beep the double beep (beep-beep) once they double beep smoothly bring throttle to zero                              and the esc's will beep once.

    f/ Disconnect battery.

    g/ Set YAW pot back to 50%



you should now be ready to fly :-) 



If you haven flown any models before I recommend you get a simulator as they are not expensive and much cheaper than repairing the quad :-)

10/ You will need to adjust the pots to get the sensitivity correct, turn the pots up until the quad oscillates then turn it down a little. This will give most stable flight.

11/ Each time you fly you will probably need to adjust the trim.



Happy flying :-)
