Well, the truth is that mechanical aptitude is a must for this hobby. If you are to be successful, you must carefully study the construction of your helicopter, and understand the flight principles that make it work. Redvtr pretty much sums the whole thing up. You can also do this: unplug your motor, and then advance the throttle from zero to full. If you observe the blades of your helicopter, the leading edge of the blade will tilt up, and you will have positive pitch. Moving the throttle down should make the leading edge go down. If this isn't what happens, then you need to flip the forward/rev switch for that channel on your transmitter, to reverse the direction of the pitch control servo. Get this right and then plug the motor back in. When we talk about a pitch curve, it is in reference to how the blade pitch is mixed with throttle. Look on your control for settings like starting point of pitch, and pitch moving range. These two things are absolutely critical. A helicopter capable of 3d flight (like yours) can usually pitch its blades 10 deg positive and 10 deg. negative. The starting point of pitch determines what the pitch is at zero throttle. The pitch moving range control determines how much pitch can be achieved in either direction. The beginner should adjust these settings so that at 50-60% throttle, the helicopter can lift itself off the ground. Your starting point of pitch should be perfectly flat, so that there is no up or down thrust at zero throttle. As you get better, you will want to adjust it so that your starting point of pitch is slightly negative, so that you can make powered descents. I don't reccomend this for the newbie because if you get scared and advance your throttle down too fast, you might end up slamming your model into the ground under force. Hope this helps.
