Cabito, did you do any initial set up when you got it before flying? Do also realize, "stable flight" w/ micro helis is a relative term

You should balance your main rotors, tail rotor and the whole heli should be balanced when your flight packs are in. If you have not done these things, search the forums and you will get hundreds of posts on how and what to do. Balancing will make a big difference.
