Questions?? 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;
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;
hobbyking . com/hobbyking/...dProduct=65171
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!

What i did was flash over my board to the latest minsoo version in xcopter. The wire color for the reciever is white ,red,black on the board then the third is the same sequence but colors are vertical. Calibrate esc over and it should work. For me it didnt so i did them one by one...that worked. Gudluck
