This video demonstrates how to use the auto trim feature with your APM 2.5 board. I'm running ArduCopter firmware version 2.8.1 and the auto trim works really well. This has helped me get my flight stabilization dialed in and almost as tight as my Naza. It's a great feature if you don't really know how to manually configure your PID settings (I don't yet).

If you are going to auto trim your APM board make sure you do it in a windless environment. Also, make sure you've successfully hovered your quadcopter and verified it flies properly before you auto trim.
