Micro indoor Quadcopter

This quadcopter was inspired by the Micro 105 FPV Quadcopter created by punkkills (http://www.thingiverse.com/thing:1221911)
The cam mount is built on the frame and designed a motor bracket so the motor would't fall off when crahsed.
Light weight, low battery, AUW 58.2g with 1s 500mah battery.
Note: the motor bracket might not work with 2S battery if you use PLA to print it, 2S can make the 8520 motor very hot and it could melt the PLA.

The motor bracket on photos is not same as mount i uploaded, these brackets was bought but i redesign the new bracket to make it printable, and it works as good as these bought brackets (i tested)
Note: There is a located pin on the bracket, make sure it fits to the hole on frame.
The motor bracket must print horizontally, so it would have tenacity and won't break when you mount the motor.
