I didn't see BJ's Etude pictures until today. My CG ended up at 275mm as well. I started out 0.6 degrees on my incident and will try 0.5 at some time to see if that make any difference. It flies so well it really isn't an issue now. After 24 flights I'm still impressed how it flies each time out. I'm flying 7 minutes with 2 - Zippy Compact 25C 5000 mAh batteries and landing with 37 to 40% left in the packs.
