Hi all ,
I want to make a quad rotor... have gone through all post available here about quad rotor.
Now i want to ask would it be beneficial to use ArduPilot for the place of Gyros ,mixers and all that...
and if yes ... what is the best option available for me...
I got a source of a ArduPilot here  ... tell me if i need any thing else..
thanks..
