Nidrah, I agree with everything but your trim example. The way I think about trim adjustments relates to driving a car.

If everything is perfect, you could hold the steering wheel straight and your car would go down the road straight. On the Heli, it hovers perfectly still meaning you don't have to hold one stick in any direction to keep it still (theoretically). But say your car/heli wants to pull to the left continously. In your car, you'd hold the steering wheel a little to the right to counteract that. The beauty with the Tx trim tabs on your Heli Tx is you can actually trim to the right so that the stick could remain centered to "trim out" the tendancy for the heli to pull to the left.

Of course, all these tendancies to pull in any direction or spin should be taken care of as much as possible with blade pitch/tracking and adjustments on the helicopter electronics (like on the Blade CP, the Proportion pot).
