what i'm having trouble with is getting it to trim.
it want to lean left on takeoff and the trim adjustments dont do much .
It is normal for most (all?) FP helis to want to slide to the left on take-off. That is caused by the ground effect. Watch videos and most pilots don't even try to compensate - they just boost up above ground effect quickly. I like to apply right aerilon for a brief time during take-off to avoid the side slide.
You may also notice a slight tilt to the right while hovering above ground effect. Again, normal. There is an explanation at http://www.helicopterpage.com/html/forces.html
These effects will reverse right or left depending on the direction of the main rotor spin.
