3DR Y6 - Spinning in place! Help!

A buddy and I just finished up his 3DR Y6 build and we've hit a massive roadblock that we can't seem to overcome. 

The Y6 WILL lift off but immediately start "UFOing" either to the left or the right, it differs each time we lift it off. 

The prop direction has been checked 16 million times so its not that.

We've had this issue with our old KK 1.5 "blackboards" and when this happened you needed to do a stick command to reverse the gyro for yaw.

We've seen many threads about people talking about reversing channel 4, but this isn't an RC input issue that's reversed, its the gyro being reversed and compensating the wrong direction, setting the Y6 into a uncontrollable spin.

Anyone have any ideas? Reversing gyro directions is pretty easy on the old KK board but apparently not even discussed with the APM 2.5.

    Six things to check (or re-check):

    1) Motor order

    2) Motor direction

    3) Prop type (pusher/puller)

    4) Props are right-side up

    5) APM facing the right way

    6) Correct code (Y6) loaded
