Title: Help me build small FPV Quad.

OK.
My another idea is to desing and build small "around 30cm long maximum" quadrocopter.
1. MUST BE CHEAPEST SETUP POSSIBLE "INCLUDING ALL WE NEED"
2. PROPELLERS MAXIMUM 6" 7"
3 LIPO TO POWER THAT THING WOULD BE 3s or 4s but 1000mAh = silly cheap ! and got 10 of them !
4. FPV ONLY ,camera+VTX ,NO OSD GOPRO ETC:.

help me choose power setup
motors
esc's
props
fc
fpv - i will go 1.2 Lawmate or 5.8 immersion
It's tiny and this build is for bushing my local park :)
don't worry about frame I will create something for that setup.
Special frame to go crazy :) and cheap :)

OK I think to start with these motors
http://www.giantshark.co.uk/product/170677/xyh28-22-1400kv-8a-outrunnner (http://www.giantshark.co.uk/product/170677/xyh28-22-1400kv-8a-outrunnner)
then add
this esc's http://www.giantshark.co.uk/product/168493/hobbywing-flyfun-10amp-esc-speed-controller (http://www.giantshark.co.uk/product/168493/hobbywing-flyfun-10amp-esc-speed-controller)
or http://www.hobbyking.com/hobbyking/store/__28159__TURNIGY_Plush_12amp_2A_BEC_BESC_UK_Warehouse_.html (http://www.hobbyking.com/hobbyking/store/__28159__TURNIGY_Plush_12amp_2A_BEC_BESC_UK_Warehouse_.html)
I know motor need 12amp esc but you never use full power on quad.

NOW ...? what props for that setup ,will go with 3S 1000mAh Lipo.

does it have to be just small or as small as possible?
does it have to be as cheap as possible?
does it have to be a quad?

ok I decide to get :.
D2822/14 1450kv motors + 12Amp turnigy plush ESC's with 8x3.8 electric props -this setup will give me around 400gr thrust each motor at 7amps or 6amps.
so 1.6kg is maximum

now need frame for 8" props ;D light and stiff then work out FY30A and some lightweight frsky receiver for that.

Have to shorten shafts.
Check props for balance.
Flash FY30A - setup.
Bind that tiny frsky receiver and make tiny wires for connections.
Oh and setup ESC's then solder all together.
Hope this one will give me some fun ,because big mammas I got give me headache and shaky legs for now :laugh:

Frame + engines +FY + receiver + props/hubs + 2200mAh 3S Lipo all together weight 775gr.
Shaft to shaft is 42.5mm

Still no idea for legs - must be light as much as possible.
