RE: Osiris Kudos
Hey Mark,
I bought the Hacker outrunner and CC Ice 100 as recommended by 3d Hobbies and I'm using my 5s 4900 to 5350 mah lipos for power. The long battery tray makes cg easy to reproduce with different batteries. For me having it balance just behind the former right in front of the wing tube is the "right" CG.
