What you make your quad from depends very much on what you have available and what tools you have.
Quads have been made using everything from wooden dowels through to hi-tech composite carbon tubes and frames.
There is also the option of buying a pre-made frame, some of these are very nice and can reduce the time it takes to get your quad into the air by quite a bit of time.
As you'll have seen in my latest video, I purchased a composite frame from China but I've also welded up an aluminum one.
The simplest DIY would be to use aluminum tubing and plywood plates.
It's interesting to note that most of the people around here who are doing FPV with multi-rotors have chosen the tricopter or Y6 layout for such activities. They seem more stable as a camera platform than the quads -- probably because, in forward flight, all the props are operating in "clean air" whereas with a quad, there may be some interaction between the front and rear props on each side.
