It's a Syma S107. Very stable and easy to fly. Got it from Amazon for 32.00 shipped. The only bad side is 40 minutes of charging for 5 minutes of flight. The cats were freaked at first but now pay it little mind.
I reccomend opening the remote and unhooking the spring on the left joy stick that controls vertical movement. I find that it's easier to control with less up/down corrections and easier to hover. There is one screw in the charge cable compartment. In less than five minutes you'll be good to go, and you can easily change back if you don't like the great results.
