I am inerested in making a totaly DIY quadricopter.
I would appreciate your answers to these questions:
Can I use a cellphone battery (or any other battery, like this one, for example this) and attach it to the USB module as power? Should I connect it to the round power jack?
Is it possible to set an ad-hock WiFi network with the appropriate elements?
Is the RAM and ROM enough to place an elaborate program, controlling the flight?
Is there a way to extend the sockets? I mean, add more points of connection?
Are the elements provided by the different makers interchangesable?
