Hey Gene, I would like to add to what Dayhead and Gluehand mentioned. I too need to be able to fly inside. And an actual "Living Room" flyer that does not require a monster living room with a 30' celieng either but a low level capable plane that can fly low circuits in an actual living room complete with walls and a tv. lol
If I may suggest Slebetman's Portable Plane.
It is a little mini-stick type plane with removeable wings & tailfeathers and fits in a small box. Rubber powered and he has posted vids of it in action. Incl'g one in a small room. I plan on building one as well.
You can also find plans for itty bitty's such as the various little mini-sticks at Hip Pockets Builders Forum.
This forum is mainly rubber powered planes and building. They have an indoor area as well. I saw a few mini-stick plans in the gallery.
Hope this all helps. I for one am going to check out the Room Flyer that Gluehand linked in.
I'll be watching to see what you build.
