herman- you're on the right track. The stock TX is designed to use the throttle trim at the bottom of the curve. This is because you will rarely if ever go 100% negative, but you will positive. This gives you more room to add head speed on idle up if you need it because it will add positive pitch. Keep in mind though that you may have to readjust the swash if it was originally set up with the trim centered. A lot of folks recommend setting the swash levels in idle up so it's already adjusted for it. I haven't reset my swash since before I read that, but I need to change my main shaft so I'll likely do it then (daggone trees anyway).

Mark- I do a full minute hands off .............every time I crash, usually while holding my stomach laughing.
