Hubsan x4 frame

This is a replacement frame for a hubsan x4, I hope to print and test over next couple of days. still need to design a top cover.
battery will need to be held in place with rubber band or velcro until I think of a better way :)
update: new version uploaded, this has been designed to mount the control board on the bottom, I have printed it in pla with .3 fill and weighs just under 10grams, could be made lighter.
update: added some more channels for motor wires, made motor holders a little bigger and changed board mount hole location a little.
26/6/13 : tested out today, little heavier than standard but still flies ok, need a couple of small screws for the circuit board. wires were not quite as long as I was hoping so could not use the grooves.
new version 1.6 uploaded, should be a bit lighter, few bits missing to save weight, not printed yet.
