Ardupilot

I have been looking into making a multirotor or a plane, and I have heard about ardupilot. I just need some general information, such as what board it uses, how to wire one up, or if it is a replacement for a regular flight controller. Thanks!

Lots of information about that here:-

One more thing. Does the Ardupilot Mega require an Arduino Mega?
