Ya I dont know how to use "friends" either. it just said that i need to be friends with you to leave u a message. That is alot of X6's. I just made the launch ramp for mine, but still have to put a hook on the plane, and get a bungee cord. Where is your hook located? I have read that 50% between nose and cg is a good start point. Then adjust from there. what size batteries do you have? What motor/esc are u using? I am using a tacon bigfoot 15 900kv 2826, 50A esc, 4400 80c 4S battery, and 10X4.5 prop at the moment. Waiting on a 10X6 foldong prop and a 11X8 folding. I know that is too much for my motor and esc, but I am looking for max flight times, not sporty flying. 

Once I get mine dialed in and it flies a perfect grid, I am going to either put a nex5r in the front for mapping, or 2 canon sx260hs in the wings for ndvi. I dont always have someone with me, so i need to get that bungee system working. I want to get cameras on this thing asap and start making some money!
