In looking over Scott Riese's trim chart modifications I offered a couple of suggestions that I will include in my own modifications, but one thing I felt was noticeable absent was handle spacing in response to the second item, "pitch sensitivity".
I see far too many posts suggesting adding nose weight on your first flight which I feel is absolutely wrong. Set the center of gravity exactly where you feel it should be starting on the first flight. That is the only way you are going to get the trim correct. If you try to trim the plane nose heavy, everythig will be thrown off when you move the CG back to where it should be. (Now "should be" is relative for each individual flyer. But you need to start where you think it should be and the notation on the plan or advice from others gives you some starting point.)
Most beginners want to add nose weight because they think it decreases sensitivity (which it does. And too much can actually make it impossible to turn). That's where handle spacing comes in. Before your first flight, check the amount of sensitivity when you apply normal (for you) control inputs into the handle and adjust accordingly. If you want the plane to be less sensitive, then narrow the spacing for the first flight or two and widen it up as needed. This will keep the inexperienced flyer from overcontrolling, while allowing him to trim the plane properly from the very start. If you start nose heavy, anything you do to trim the plane while in that condition is a waste of time and will need to be done all over again when you get the cg back where it needs to be (if the plane ever lasts long enough for you to do it).
Some have suggested starting with a fully adjustable handle, and then, when they have the plane in trim, making up a handle with a fixed spacing for that plane. That may work for someone like Windy who has vastly superior skills to most of us (excluding a few of the top 5 flyers on this board). But we find ourselves making minor adjustments throughout the year just flying one airplane. And for those of you flying multiple apirplanes, I can't imagine flying each one with a fixed handle spacing. No wonder some people report "that design won't turn". It is not trimmed properly. Having the ability to change the handle spacing in minor increments as needed will vastly improve your flying skills.
And starting with the proper CG will enable you to get that plane in trim and flying correctly much sooner.
