I have the new HK KK2 hard case. Are you talking about the procedure where you power on the DX8, push the throttle full, then hit the 1 and 4 button at the same time?Calibrate them all together if your FC allows it or individually direct on your RX if it doesn't.
What FC you using?

Worked great...motors are humming. I was having trouble with my KK2 "Hard Case". I kept trying ACC calibration and it always failed. It said Acc Z "Not Ok" Well I have seen many posts about the same thing. Well here is the problem. Of course you point the arrow forward, BUT it seemed natural to install the board arrow forward and label up. I flipped the board over with the label down. Bingo! problem solved. I'm telling you all this in case anybody asks.Thats it.
Hold 1 and 4 as you power up the quad (PROPS OFF FOR SAFETY)
Keep holding them and bring throttle down etc.
Best to have someone help as you need too many hands.
