but i want to make it autonomous using APM FC. Is it possible to make it autonomous by just changing the Flight controller board by APM 2.8?? Is firmware available on ardupilot official site compatible with APM 2.8?
Yes, it should be straight forward.
Just check the manufacturers compatibility of the APM2.8 which I am assuming is a clone Pixhawk.
The APM2.6 was the last 3DR branded 8 bit controller and it still works well using the 3.2.1 version of the Arducopter firmware and will do autonomous stuff.
The new 32 bit processors are in the Pixhawk and its derivatives.
Just be careful as there has been a lot of Chinese cloning going on of both versions.
