hmm, well, to reply to the message about getting what I paid for: this thing wasn't exactly cheap. Only the heli itself cost $550 + I had to buy a receiver, a transmitter and the batteries (one battery costs $90). So it isn't that cheap crap that people mention here. So for absolutely everything I paid something like $1200 (if converting to USD) (I got a good transmitter for $400 and 2 batteries).

And it says on the label: RTF Version and says, that servos, gyro, brushless motor and this voltage controller thing for the the motor are installed. Basically the only missing part on the heli is the receiver and battery + plus blades and a lot of some small parts which I don't know how to put together...

What the manual does say, is that I have to check the blade balance for vibrations and so forth, but how do I get it to the state where I can balance the blades I don't know...

Too bad I will have to go through absolutely every manual over there, I have expected something more comprehensive.
