This is a V-tail quadcopter that I designed on Sketchup and created on a Solidoodle 3D printer. The arms are held on with Dubro servo mount screws. I used 1804 2300kv DYS motors, KK2 mini control board, Favourite 6A 4-in-1 ESC, 6 channel micro receiver, and Nano-tech 950mah 2S battery. I have had good luck with the 4-in-1 ESC. It fits right under the control board very neatly and the single power plug cuts down on the wiring. The wiring from the ESC's to the receiver is a little tricky, but it was worth the trouble. There is adequate room on each motor mount arm for individual ESC's, if you decide to go that way. For FPV flying there is a camera mount in front and also an area on top of the rear mount for the FPV Transmitter. The Carbon Fiber tube is 12mm in diameter. The tube length is 248mm or 9.75 inches. I'd like to say that there was some scientific method used to arrive at this length, but it's actually a 19.5" Carbon tube cut in half. Here is the link to Thingiverse where you can download the files to print one.
