Go here and start reading! This is the best explananation that I have seen in a long time. It was written by a newbie while he was doing his research to get into helicopters. About a year later, he revised the publication and made it even better.

short answer is that there is a trim tab under the right stick, move that tab to the right a notch or two.

Any heli with a tail rotor will try to drift.
In most model helis the tail rotor thrust to the right to compensate for motor/engine torque. One of Newtons laws come into play here.
"For every action there is an equal and opposite reaction"
The right thrust will try to push the entire heli to the left.
Using the trim switch you can attempt to correct for this by adding right aileron trim.
I try to make mechnical adjustments my self to keep the trim switches as close to center as I can.
The mechanical adjustments are screwing the ball links in or out on the servo to swashplate connections. On the ailerons on most helis with 3 servo CCPM setups I try to keep the aileron and pitch servos even by making one turn in on one for every turn out on the other.
By doing this I can keep my swashplate level with the elevator and avoid changing collective pitch settings.
As Rafael23cc said, do some reading and find out more about how your heli works. It will serve you well in the future.

I'm not saying my answer is better but it was a simple question and I gave him the simple answer, I'm not saying it was a better one or that what you said was wrong. Please don't get on my back for answering the question he asked.

I understand that but no where in your post did you actually answer his question. You gave him links to learn more himself, I answered his immediate needs. He got everything he needed. If you had not posted the info you did then I would have answered in more detail....

Would damaged blades(just the ends) add to the severity of the problem? Thanks

It may throw them out of balance and cause more problems down the road, including just plane coming apart and flying at high speed into the nearest object, maybe you.
The blades for that heli are really inexpensive, I would replace them ASAP. Your heli will run smoother and not wear as as quickly.

I replaced the blades and found that the problem got better but was still there. I read that there is more turbelance in the air closer to the ground than at like 6 feet. Could turbelance be causing this? Thanks

If you are only running like 1 or 2 feet from the ground, then yes it could. Most heli's that size need to be about 3 feet up before they leave ground effect.

Yes I was running it close to the ground and I took it up to like 5 or 6 feet and it seemed more stable but then I crashed it because I don't know how to fly one. My tail boom( i think thats what it is called) came loose and swivels even when it is not off the ground yet should I just ca glue it back into place? If the blades are chopped up at the end can I still use them because if i switch them again I will just ruin another set. I am using the foam blades with carbon fiber rods for reinforcement and the plastic shrink wrap type stuff on the outside. Thanks

I Ca'd mine when it loosened.
Not only is the air more turbulent near the ground but if you are flying indoors the wash will bounce of of the walls and have an effect.
About 1-1/2' to 2' off the ground should be plenty to get out of ground effect.
I normally like to hover at about knee to waist high.
