Fun.
I purchased a bunch of remote controlled "flying saucers" for Christmas presents. They were less than $8 each counting freight, and could fly for a few minutes. You can control the speed with a little hand controller, and the trick is to keep it off the floor and ceiling.
Really a hoot. Took one outside and flew it up about 40 feet and lost it in a tree. Decided not to get it.
