I can't recall on my Edge (same one you just bought), but I believe it was somewhere around 5.5". I'll have to confirm. I calculated it out to be 27% MAC, and also have tried flying it at 31% MAC which was REALLY tail heavy. Check out the manual from another plane like the Sukhoi or Yak as they have the Edge's CG at the end of it as well. The plane WILL come out tail heavy, so do all you can to keep everything up front. Check out our build thread and my big flight report on the plane for more details. You're gonna love it! Crash likes it more than his Extreme Flight Yak 88"! lol
