I just wanted to let everyone know the Kickstarter for the Game of Drones combat tough quadcopter airframe is in it's final 24 hours. They are already funded and actually very close to their 50K target. Check out the videos, pretty impressive. I have been flying quadcopters for a while now and I am excited to get a frame I can beat around with much more. I wish this frame was out when I was learning to do flips with the quadcopter - me the gang at the office have a stock of F450 arms and we've gone through them. I am excited to get us setup with a few of these to get some fun combat going on. Especially now that DJI is dealing with some legal issues, not sure how easy stocking the F450 arms will be. If your a beginner this would be a nice frame to let you focus on flying and lower your worry about crashing. Check it out here is a link: Game of Drones Kickstarter
