e-Century Hummingbird - Swift > Is my heli tail heavy?

I balance my heli according to the manual by holding the paddle stick and check the skid is level. I have done that many times and actually put the battery slightly more forward to make it slightly head heavy. By when I fly the bird it has a tendency to fly with the tail lower (the boom not pararel to the ground). Everytime I try to hover it will move backward. If I try to compesate it with elevator if fly forward. I have a stock setup and I already pushed the battery close to the end of the stick just enough space for the small tubing to hold the battery.

If the skids and the tail boom are parallel with the ground when you hold it by the flybar, then it is balanced and that is not your problem. A heli is inherantly unstable, and will never hover hands off, but if it always flys backward when you have it several feet in the air, then your problem is trim. Try taking it up a few feet, see which direction it trys to move, then land and adjust your trims. Keep doing this until you get it trimmed. If when it is flying backward, you compensate with the elevator, and it starts going forward, then you are overcontrolling. If your transmitter has exponential or adjustable travel volume, you can adjust them to make it less sensitive, but mostly it just takes a lot of practice.

Balance

I am suppose the balance it's okay, I need to trim the heli better. I have travel adjustment and set at 80% on all except throttle. No exponential on my radio. I am not very discipline with my learning I like to try to hover it by trying to adjust left, right, forawrd, backward etc. Maybe I should spend sometime trimming it even though I did that many times already. Thanks.
