This tiny  Micro-Quad features an integrated PCB frame, Simply bolt on the motors then solder your choice of 6amp ESC directly to the frame!

An integrated power distribution system is also included making for one of the neatest electronics installs around. All mounting hardware and frame components are included in the kit. All you will require to have this little monster in the air is four Turnigy T1811-2900kv motors, four 6Amp ESCs, a set of 5x3 Micro-quad props (2 Clock wise and 2 counter clockwise) an 800mah 2s 7.4v Lipoly battery, a HobbyKing Multi-rotor control board and your own transmitter and receiver (Tx/Rx).

Light weight design.
Integrated PCB for component installation.
Included a full set of frame and mounting hardware. 

Flying Weight: 145g (not including RX and battery)
Width: 250 mm
Height: 85 mm

Available from Hobbyking for US$ 14.99:

Now that is a clever idea, that is flipping obvious. Well done HK.

very nice. And the hole in the middle looks just perfect for poking a camera through and performing some optical flow. Thanks for making me spend my money!

That's pretty neat.  Sure is small.  I added up the price for the frame, the V3 board, 4 of the Turnigy ESC's, 4 motors, and 48 propellers, came to $125 or something.  Not bad.

How well do those HK boards fly?  I wonder if it's possible to reflash them with some kind of stripped down version of Arducopter?

Looking forward to reading about this once someone builds one.

Cool but this has been available for months:

I wonder why these laser cut frames are usually designed so that the engine strut is very wide. Wide engine strut blocks the downwash of the rotor and reduces efficient lift. Why not increase the strut height dimension and reduce the width as thin as possible so that the air flow wouldn't be interrupted by the struts so much?

Veikko: Mostly price related. Thicker plates cost more and take longer to cut. But I would not worry. Propeller blades has close to no lift at the base. Most of the lift comes from the outer 2/3's of the blade.

Appears the PCB microquad is the hot item (from researchers to consumers) currently...

Not bad at all: HK comes through again with a reasonable design and hobby price. Sure it likely could fall apart after 2 crashes, but still.

I'm wondering what phenolic grade they are using, cause you [really] can't laser cut nor waterjet cut G9->11 and G3-8 burns or melts easily on the laser. 3-axis CNC could be what's happening here and it's just easier to cut bigger shapes.
