I trained with all that stuff except for that AFS system that we tried (we being my instructor and me) but did not like it at all. So, we just never connected it. As for the other stuff, it did no harm nor did it do any good. After I solo'ed, I took it off. No big deal, just a little trim adjustment in the elevator and it was fine. I seem to recall that it did cause the plane to come in a tad steeper, or maybe that is vice-versa, not sure, that was a while back.

Bottom line, if you don't have it on, no big deal.. I wouldn't waste any time with any of that stuff. Just put the engine and radio in there and get your instructor to help you learn to fly.
