The Walkera Ladybird quadrotor can be summed up in one short word: FUN FUN FUN
This is one stunningly enjoyable RTF quadcopter and it is also, from a technical perspective, a brilliant piece of miniaturization.
Perhaps the most amazing thing about this little craft is that it's just as much at home in a 15kph wind as it is, hovering around indoors. It's one of the few RC models you can fly in even the smallest back yard.
After many, many crashes, mine is still going and begging for more punishment.
I would say that anyone thinking of getting into multirotors could do a lot worse than invest a little money on this model.
Unlike many of the RTF coaxial helicopters, this comes with a real man-sized 4-channel transmitter, the Devention 4, on 2.4GHz and the craft itself is totally is unfazed by wind and turbulence.
One of the best products I've seen for 2012. Definitely a big RCModelReviews "thumbs up".
