There may be a difference between the kit and the ARF that could account for the fact that I have room for the battery. My battery is a flat, four across configuration, but you probably assumed that. If I remember correctly, the tray for the fuel tank had a rectangular hole cut in it. I was able, with a little "convincing", to slip the foamed and "baggied" battery through the hole so that it would sit wedged between the bottom nose sheeting and the fuel tank floor. Of course, I may be thinking of another plane , but I'm 90% sure of this. I'll confirm when I do my "bow to stern" check later tonight.

You say the outlet is "spinning" around? Are you saying that sometimes it points up, sometimes points down, etc ...?
