Hi and welcome to the new world of r helicopter. If your using the stock transmitter, what you need to do is put all the trims inthe center except for the throttle trim, and make sure your swashplate is level. There's a video here from nuttcaze on how to setup your helis. Keep in mind though that not only your swashplate is level, you need to make sure that your servos are also in 90 degrees position . This way you'll have enough throw on both pitch. It would be better to watch nuttcazes video on how to setup this specific heli. Good luck
