Question KKmulticopter V5.5 - need calibration help

Hello all,

Im building my first 3D printed quad X copter from scratch and I'm nearly done
However, I cannot figure out how to properly setup my KKmulticopter V5.5 black board flight controller;
http://www.amazon.com/docooler-KKmul.../dp/B006U9KX2K (not sure what the 1-3 split servo cable is for)

When I power up the Tx and quadcopter, arm the FC and begin to throttle up, only 3 motors begin to spin. The 4th motor only begins to kick in at about 75% throttle.
This happens to whatever motor/ESC is plugged into the #4 motor output on the FC.
Ive tested and confirmed each motor/ESC works as expected when plugged directly into my Rx. The FC is properly orientated, facing forward.
I followed the steps to calibrate the throttle range; yaw pot to 0%, full throttle, power on the system, wait for the flashing lights and bring the throttle back to 0%, hear the multitone beeps, power off and reset the yaw pot. When I do these individually, motors/ESCs 1,2 and 3 give the proper multitone beep when calibrating the throttle range, but motor/ESC output #4 only gives one solid, short beep.

It appears that the board and electronics are working, just not properly calibrated.

I followed the instructions listed in the comments and what documentation I could find to get the drivers, GUI, and firmware. I used lazyzero's KKmulticopter Flashtool to install v4.7 X copter firmware (by KapteinKuk) on the flight controller.

These are the motors and ESCs I am using;
https://www.hobbyking.com/hobbyking/...dProduct=65171
https://www.hobbyking.com/hobbyking/...dProduct=64410
with a Futaba 7CAP Tx (I did make sure to reverse the throttle for Futaba)
Going to KKmulticopter.com (printed on back of the board) brings you to a dead website.

Is there something I am missing or doing wrong?
Any help would be greatly appreciated!

Many have had similar experiences.....try this link and follow the additional threads.......it's a good starting point:

Much luck with it....the firmware up-dates are continously being modified, that's a good indication you'll be pulling your hair out for some time to come.......

Thanks for the link. Looks like others were having similar issues. I have the recommended firmware loader, maybe more tinkering with that will produce something.
