There's no room to move the battery back,unless I put it behind the servo tray,wich would be aft of the trailing edge,and I'm not sure I can get my fingers back in there to work with it.The servo tray was pre-glued in by the factory,so I had no choice in where it was located.Seems really cramped in there.Kinda hard to picture what you are suggesting.Are your batteries located behind the trailing edge of the wing,in the back side of the fuse?
