Ok, so not very original, but its my take on a Quadcopter design, i have used ø12 carbon fiber tube for the arms every thing else is either 3D printer or laser Cut. Has a Go Pro Mount its runs on Ardupilot. IMPORTANT! After having quite a big crash today due to the carbon fiber tube twisting, please ensure you drill and pin a cross hole through the motor mount, and through the top-lower deck mounts to prevent any rotation of the tubing!
