    Get extra motors,  my luck has been 1 of 4 have quality issuse.  I would also use 2 of the 3000 mha lipos together.  11 x 4.7 prop should work nicely.  The Turnigy 9x is an awesome radio just don't plug the battery in the wrong way or it will destroy if self.

    Those ESCs do not have a BEC(battery elimination circuit) -a voltage regulator to feed 5v to your Rx(receiver) and APM. So you will need to add a BEC to your list.

    Those motors have a Kv rating of 1100, which means the motor will turn 1100 RPM for every volt that is given to it, so 14.8v =16,280 RPM. I think that is a bit fast for large 12"+ props, You might want to look for a slower Kv motor. Big props spinning slowly are going to be quieter with good lift and stability, that's nice for hauling a camera system, and more pleasant to be around also.

    You definitely want more amp/hours in your battery pack with such a large power system, like the others have said.

    Hi Mark,

    The Radio is OK, 8 Channels with low price and a lot of possible 'hacks' to improve it

    The motor seems very oversized, and the 3300 Lipo will be empty shortly after starting.

    If you realy need so much power, I would suggest a 6600mAh Turnigy nano LIPO, 

    but be warned this quadro will have a lot power (600W per propeller), nothing for a beginner.

    if you are a first time quadcopter builder why not just buy a proven kit on jdrones.com ?
    this is they easiest way to get you started and the staff there is really nice. They have hand picked the right combination of parts to ensure they work great plus they have the best customer services and most of us around here will be able to assist you because that is also what we use.
    anyhow, have a look on the store.
    For Lipo, you want the highest amps possible but also the weight is important... I fly nanotech 3300 and it's really nice.
    the radio, go for that one, it's what we mostly use. search around here and you will see a lot of tweaks you can do to it.
