Make sure your swasplate is level. That is probably the cause. First start by unplugging the motors. Then plug the battery in and go to half throttle and flip the switch on the top right of the transmitter towards you. Then you will probably see that the swashplate isn't level. Most likely you will need to lengthen the pushrod on the LEFT side of the helicopter looking from the back. And it is the pushrod on the outside of the swashplate.
The top right switch is the idle up switch. That adjusts the pitch and throttle curves, so you get negative pitch below half stick and the throttle also starts to increase below half stick. That is when the switch is torwards you. Then when it is away the throttle curve is linear and there isn't that much negative pitch.
The rotary knob in front of the idle up switch is for the gain on an external gyro.
Don't worry about the servo reversing switchs as those should already be in the right spot.
The four sliding switches by the sticks are called the trim. I now realize those aren't stated in the manual. The bottom left one is for the rudder. Move it right and the rudder will want to go to the right more. The one to the right of the throttle stick is for the throttle trim. You need that at the very bottom when you plug the battery in or it won't arm. If you increase that you will get more throttle. The one to the left of the right stick is the elevator trim. If you push it forward the helicopter will want to tip forward more. Then the one right below the right stick is the aileron trim. Move that to the right and the helicopter will want to tilt more to the right. This is the one you could move more to the right to keep it from drifting. But you should keep most of those in the center and do mechanical adjustments instead.
I can't remember what the top left rotary switch does, but it should affect either pitch or throttle curve in idle up mode.
Hope that helps.

So are you saying it is still drifting after that? Then are your blades tracking in the same plane? And are your flybar paddles parallel to the flybar cage? Do the links move freely and not stick on anything? After all that and it still drifts just add some right aileron trim and that should get rid of the drifting.
When the motors are unpluged and you move the throttle up does the swashplate tilt to the left?

Sorry but I don't think I told the problem right the first time. It is drifting to the left and forward but it is also spinning counter-clockwise very slowly. I'm not sure if I still have to adjust the same things thought. Thanks

I still think the swashplate isn't level because those are all the symptoms of one. It doesn't take much movement in the swashplate to cause a change in how the helicopter flies. Try shortening the back right servo pushrod a half a turn or a full one and see how that goes because it sounds like the front of the swash is tilting down and left. For the rotating try turning the propotional potentiometer clockwise a little at a time on the 3in1. It doesn't take much of the potentiometer to affect the rudder.

Yes, that could affect it big time. If that circle part of the training gear is under the mainshaft that should help and moving the battery back. You can hold the helicopter by the flybar with the blades parallel to the boom and see which way the helicopter tilts. And no telling how much the damaged blades are affecting the flight.
