That's the exact setup I've been running. I've only flown it in stabilize mode so far (running 3 6s 5000mah batteries) as I am waiting for an APM 2.5 case right now before trying out the other modes. However, it was very stable for me in stabilize with the default settings.

Can you post some pics of your APM installation? The flight looked very smooth.
Here is my S900 Clone setup with apm 2.5 rctimer clone. Next I will be adding FPV.
