quadcopter FPV gear payload?

I dont know much about quadcopters but Im interested in getting one for the following reasons but mainly because that they should be more stable compared to my heli and be more of a joy to fly. Ive been eyeing this frame and was wondering about the kind of FPV kit it could carry. Could it lift and fly well with an an FPV setup with an RVOSD + go pro HD camera or can it not handle a great deal of weight? I know this depends on the setup you have so lets just say it would have the best motor + esc setup suitable for this application because that is what I would get.

If anyone has this frame it would be great to know the kind of weight it can handle. Also I know this is just a frame but Im mainly reffering size of the quadcopter and the kit that would you normally have on it to get it to fly and be suitable for FPV.

thanks in advance

If you translate German you can read that the frame itself has 250 grams, and there are two recommendations for engine sets, for up to 700 grams, and over.

Motoren: Bis 700g Abfluggewicht: E-Sky EK5-0002, ROXXY 2824-34 (oder Motoren mit vergleichbaren Werten)
Ab 700g Abfluggewicht: E-Sky EK5-0003, AXI 2217-16, AXI 2217-20 (oder Motoren mit vergleichbaren Werten)

For tricopters fitted with three 2217-20 there is no problem to lift 500 grams payload, so for a quad you have even more.

which quadrokopter plattform do you plan to choose ? If you plan to use a Mikrokopter you can have a payload of about 300-400g with the standart Setup. If you want more you have to go for more engines or different blc because the standart MK BLC can handle only about 12 amps.

As already mentioned I dont really know anything about quadcopters but its something Im getting more interested in. What are my choices?

Also what does BLC stand for?

I thought thats what it stood for but it was just a guess I havent come across BLC at all ESC is used much more I guess.

Can anyone refer me to a thread on how to quadcopters work and what I need to set up one?

I was looking at the mikrokopter electronics and its a lot of money. I think I'd have to spend about 800 just for the quadcopter without the fpv kit I'm also wanting to get am I right?

There are many many many designs out there. For price, you can look at ones users on this forum home built, or go for a less popular, just emerging company.

I'm myself building a KapteinKUK quadcopter. http://www.kkmulticopter.com/ for under 50USD for the controller board.

What is the feedback on that controller board though?

Also this is a noob question but Im trying to work out how the quadcopter moves in any direction and can pivot? How would it do that the motors dont tilt so all I can think of is when the user inputs forward cyclic the front motors power reduces compared to the backs causing it to tilt forward and thus move forward? lol

Are they easy to control or not? (Im a heli flyer)

That board has great feedback, as long as you can solder. However you can buy ready built boards for a little extra.
To yaw and pivot, it lowers a motors speed relative to the others.
From what I read, it should feel almost like a FP heli.
