Our club started doing indoor flying this year. It has been a totally new facet of flying for me and I have enjoyed more than I thought. It's a total blast.

I have several of the Air Hogs from Wal-mart and they do work. I also have a Park Zone Citabria that I fly, as well as a Eflite Blade helicopter. Many at our club fly the Citabria, the Park Zone Ember, and the new Park Zone Vapor. All three of these are outstanding indoor fliers. They are all 3 channels and you won't have any problems handling them indoors. We've had people that have never flown before successfully fly them for the first time, they are pretty easy to fly.

Hope this helps
