Description This is a "full bodied" quadcopter design based on the same arms (and other ideas) from the T6 hexacopter. If you're after something a bit simpler then I've also put together amashup of MikeyB's Crossfire 2 and the tubular arms that feature in this quadcopter. Features: completely 3D printable (without support) simple assembly includes a single motor arm or optionally use the coaxial arms from the T6 and create an X8!! strong braced tube section arms with plenty of room to conceal motor wiring designed for a single 3S or 4S battery located right in the center of rotation/thrust with room for up to a 6000mah 3S or 4200mah 4S battery (155 x 50 x 30mm capacity). easy cable routing with beveled cable "tunnels" (and even a few cable tie mounts) plenty of space to mount ESCs - concealed but still well ventilated for cooling - perfect for a 4-in-1 ESC too. top plate is designed for the new Pixhawk flight controller from 3D Robotics - but can easily be tweaked for others RF "invisible" frame - as opposed to carbon fiber or aluminium Frame weight assembled (with bolts) is about 460g and feels really solid! Hover flight time test to come (my 4-in-1 ESCs should be arriving this week ) Sketchup file included so you can make changes to suit yourself Source: http://www.thingiverse.com/thing:261145
