darkwombat,
No hovering in the living room until you can do it outside, unless your living room has about a 15' x 15' area with nothing in the way. Still, I wouldn't recommend it.
It's really your call on this one. Where I live just going outside is not an option and I don't have time to just drive somewhere. My flying space looks like the lower first photo. I learned how to hover in this small space and it pays off when you do go outside because with this out side seems like your flying in outer space. There just seems to be so much room. If you can hover in this small space, you can hover anywhere. The dimensions are 8 1/2 feet x 11 feet. Trust me, if you can learn to hover in a small area, it will pay off in the long run. You'll amaze your friends by landing on things such as coffee table, foot rest.
