Hi Sulman, after reading this article: http://www.simhq.com/_air13/air_428a.html I have found that a combination of "hold-trim -> turn -> release-trim" and what I call "progressive maneuver trimming" works very well for stability and quick response situations. My technique for progressive maneuver trimming is: from any current stable flight attitude(ie: the ground, a hover, or forward flight) to begin by holding the trim and moving the controls to achieve a new attitude in the direction desired and then release the trim and watch that the heli continues as expected. As soon as I notice the the flight path is starting to "wander" I hold the trim, adjust the controls and again release the trim. This is continued constantly as the variables change. For example: If at a hover and I want to begin forward movement, I hold the trim, push the nose forward to 15 degrees, and release the trim. Once picking up speed the heli will start to veer. I then hold the trim and adjust slightly and release the trim. Its like saying "hold this until I say otherwise," but the advantage is that the corrections stay minor and flight is kept smooth. I can always use direct stick input on top of the trim if I need it immediately. You can also do this in turns. Hold the trim, start the bank, and release the trim. As the turn progresses and the wind direct and speed change adjust the trim again or just use the stick to keep what you're looking for. Once you are getting to the heading you want hold the trim, level out and release the trim again. It will start to feel much more relaxed with time and practice. As for hold-trim -> full-maneuver -> release-trim: Since holding trim stops all auto-input, if I need to leave in a hurry I can hold it down indefinitely, though it rarely seems necessary to do that. I can see the danger, hold the trim and start very quickly way from the unwanted situation, and release the trim to continue in that direction. This is a much more gross movement "go-right-now" technique. The thing to remember is that trim holds attitude for the variables at the time set. The further way from those variables you get the more unstable the trimmer changes are going to seem. If you trimmed at takeoff with a crosswind, full tank, and all weapons. When you get to the target area and have launched a few missiles the original trim isn't going to mean the same thing, specially if you aren't facing the wind the same way.
