The new Parkzone Cessna Centurion 210 micro RTF plane flies very very well in small spaces. Other choices for backyard flying could include the Parkzone Slo-V, the GWS Pico Tiger Moth, GWS Slow Stick, GWS Pico Stick, or GWS Pico J3 Cub.

Remember that these small lightweight flyers aren't well suited to breezy conditions (notice I didn't even say "windy," merely breezy conditions will splatter them) and you will want to be choosy as to when to fly them.

A number of skilled RC pilots I know still purchase Air Hogs planes from Target and Wal-Mart to fly indoors or to throw around the back yard. They can be a good way to horse around when you can't head out to the flying field.
