• 4 Arms
  • 13mm×10mm aluminium (cheap-ish from B&Q): Can run wires inside. Or,
  • 25mm+ would allow us to also put the speed controllers inside.
• flat top piece for holding electronics
• something to cover the electronics
• flat bottom piece for holding camera mount
• Landing struts (with enough clearance for a camera mount)

• 4× rotors, 2 of them counter-rotating.
  • 2 blade http://www.toddsmodels.com/product_p/epp1045.htm
  • 3 blade http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=5248 http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=5250

Arms would be able to pivot around a central joint, similar to a pair of scissors.

one long arm would go all the way through, 2 other arms would be hinged to the top & bottom plate, with pins to lock in place.
