Those planes are WAY too big to be flown indoors. It's not even all that easy to fly a plane the size of the E-Flite Extra in a small soccer field. If you want a truly indoor plane, go with either an Ember or a Vapor.

If you're talking about inside of a basketball court, any foamy up to about 16oz (Charger CR-1 is my suggestion) is going to be fine.
