Hey leventor,

It's normal for a heli to want to slide to the left on takeoff, which is caused by the tail-rotor, blowing the whole heli to the side while compensating for the torque of the main rotor. Once you're in the air and in a stable hover, you'll notice that the heli will lean to the right slightly to compensate for this effect. From my experience with it, it's best to trim the heli out for a stable hover and compensate for the drift on takeoff and landing. Put a training-gear on and try increasing throttle gradually, while trying to compensate for the drift. At some point, the left side of the training-gear / skids will get off the ground first, followed by the right one, and it'll take off into an angled hover. It only took me a couple of takeoffs to learn to do this automatically. A big home-made training-gear (about 2x the width of the main rotor) helped a lot in giving me the confidence to try my first liftoff without beeing afraid of tipping it over. :-) I now use a much smaller stock training-gear, which is actually slightly shorter than the main rotor.

Note that I have a T-Rex 450X, which is appearantly one of the more stable heli's in it's class, due to it's size and weight. It usually lifts off quite effortlessly, with very little ground-effect.
