I have had this heli now for about 2 weeks. It is amazing and loads of fun to play with. Quite difficult to operate, but with practice it gets easier.
One comment is the amount that the helicopter needs to be "trimmed". The majority of the time in flight (for me) is spent trying to get the heli not to spin. Once you get that right, it's quite easy to fly.
The throttle is also spring loaded, so once released all power is taken away, which too makes it tricky to fly it.
The heli is quite robust, and have hit the ceiling, walls, doors and even the telly a couple of times without breaking. It will break if you are not careful, but it can withstand most of the normal training accidents you would expect.
Don't even think of flying it outside - you will most likely lose it. It is so susceptable to wind that if someone walks by when it is in flight, you can see the heli getting blown around.
All in all, a great toy, would definitely recommend it.
