Blackie, I may be wrong on this but I'm gonna give it a shot. To get your heli trimmed in, set your trim sliders to mid position except the throttle. It should be set all the way down. These trim sliders allow you to make minor adjustments to your servos. Example: one servo is a little twitchy, moving on its own (you can hear this), you would then set the trim to add a little more/little less power to the servo to 'trim it' out.
Second, you need to be sure your swash plate is level to the main drive gear, with servos on. Front and side measurements are required to get it right. I'm sure you know to balance your blades.
Once you got that correct, starter up and see what she does after you get out of the rotor wash. If she leans left all the time, then you need to extend the left control arm on the swash plate 1/2 turn at a time. To my understanding, you should also move the right one the opposite direction if you need more adjustment. In other words, try to keep the adjustments as equal as possible. If the 1/2 turn didn't do enough on the left, a 1/2 turn on the right would be the next step. If it drifts right then just do the opposite. Same goes for the forward/reverse pitch. Only one servo arm here. Again, 1/2 turns until it's close to steady. You will always have some inputs, no getting around that.
The trim on your throttle does not adjust head speed in relation to pitch. It actually adds a micro amount of throttle, as if you moved the stick that hair amount. I think your bird is collective pitch, that means pitch is automatically added as you increase throttle, you'll see your swash plate move down as you increase throttle, adding pitch to the blades. I believe this is also adjustable by shortening/lenghtening the pitch control arms but I'm not at all sure about that.

If I'm wrong here now would be a good time for a pro to step in and straighten us noobs out!!!
