This is a remix of my Micro VTail Quadcopter (http://www.thingiverse.com/thing:1209228)
People was asking for a "regular" quad version of the vtail, this is it.
Download the canopy and feet from the vtail page
The same instructions as for the vtail
UPDATE 151221:
Added a skirt without holes for motor wires since they are unnecessary for the spider config
