This build started out as a salvage of a BlueskyRC Hex. One motor and esc gave up on me and landed in a tree. broke a few booms on the crash to the ground. So I started looking through the Flite Test Store for my next victim. The BlueSkyRC hex was a great kit but Hexes=more potential failures so I started to think simpler, TRI-copter? Found the Bat Bone kit then started immediately complicating it, LOL. List of parts, two Bat Bones frame kits, 2 straight motor mount kits 13-370, 4 booms cut to 168 mm, two 1/2"x28 1/2" booms glued side by side with clear Gorilla Glue, 4 Suppo BL-2208/14 motors (will upgrade later), ESC's HW 30A, Ardupilot Mega 2.6 controller, Fr sky TFR6-A (home made 90degree antenna booms) RX Futaba 8fg TX, Fatshark 250mw video TX, 2x 2200 mah 3s Lipo, and two 6" servo extensions. Im sure I missed some odds and ends velcro ext. I started building it today but I hope to fly it tomorrow weather permitting. It measures 450mm center to center of the prop nuts. The CG is just in front of the rear Bat Bone frame dead center of the Ardupilot with the gopro on. I have a Finwing 390 Pan & Tilt for the gopro, going to remove the pan.
