Got this for my son for Christmas and I have to say was dissapointed with it:
The USB cable was not in the box (it is supposed to be included).
On the second flight one of the wheels fell off.
The on/off switch seems very stiff and hard to move.
The helicopter ISN'T gyrco controlled (get a gyro controlled one as you're not constantly having to trim it).
An the throttle stick is weighted and returns to off. I prefer non-weighted ones as you're not constantly having to apply pressure to keep the heli on a hover.
There are better models out there. My brother in law has an almost identical model which appears stronger, more flyable and is gyro controlled. I got myself an S11G which is superb.
