Pretty good price.

Just use this calculator ,it considers efficiency and other things, thrust is really dependent on what props you are using, and it is somewhat conservative so you'll be fine. Just looking at your build it looks just fine.

Looking great, where is this at?

How many amps are your motors and ESCs rated for?

I would buy some of Turnigy's areodrive or preferably Turnigy's mutistar motors. What frame and what power distribution?

Haha, I need this frame. I was gonna get some CF tube and sheeting to make frames with, but aluminium is just so easy to work in comparison.

Did not think it would with that bracket tight and that CF tube in haha, weight?

Buy 10x4.7 props instead, more lift and will fly a little better. I'd suggest this battery (or the 4S version if you want to go 4S), or two smaller ones (to use then swap out) if. What type of LEDs you using? Most LED strips are 12v, and a 3s battery is 11.1v - 12.3v, I used regular...

Looks like a great design. Is that a picture, or rendered? Haha, I'd like to se you try to break that. How much flex it have when you twist the arm?

Bout all places that have props will have both, they may go for different names like normal rotation and reversed rotation.

Battery supports 243amps, the motors around 32.5 amps, all checks out on ecalc too, grab some wooden 10x6. http://www.hobbyking.com/hobbyking/store/__1574__265__Hardware_Accessories-Turnigy_Type_E_Cherry.html

Haha, it will cut 1/8 wood, I built in 5 minutes, but the hardest part is getting the power and wire right, it is C shaped like a drill press, and works GREAT for foam ans plastic. Surprisingly easy to make...

What motors are you using and, ESCs, battery? You may be able to use them, they'll provide plenty of lift. getting that pitch I'd suggest wood that is for electric, it is a little cheaper than CF and a will last a lot longer.

I make a lot of my specialty tools xD, like a hot wire cutter, dremmel press (for PCB), and a lot of other things, but this shop is FULL of tools to use, but they are all older and most for wood work and a few different types of welders, bearing presses, and cutting torches for basic steel work.

I was going to make a CNC but then I got into quads, it would not be too hard. And have made a lathe for aluminium outta a drill that is geared really high and a hand grinder. It works PERFECT.

10x5.5? Those are plane type props probably, make sure the motors can handle them and that they won't stall out when you get a little high.

All hobby grade motors should be 3 phase. It does not matter which two wires you switch, any combination of the wires will work. That weight to thrust ratio should be fine, most calculators are fairly conservative on their estimate.
