trim control vs airspeed.

Walter:
This confuses me.
You say that you do not have to change trim settings when you change
throttle settings.
Can you tell me what happens when you pull the power back from cruse? Does
the aircraft begin a descent and hold to the prior level cruse airspeed?
Or does it require you to push the nose over after you close the throttle?

If yours is not stable in pitch, you may need to adjust your elevator trim
slightly. With mine it is completely hands free, unless fuel/pax really
unbalanced, or non cruise flap setting. Can even fly feet off the rudder,
with the right power setting. My flap setting though, does change the roll
stability, I assume because of the prop wash, with full flaperons instead of
separate ailerons on the Rebel.

I actually like the near neutral stability in roll and pitch. I can take my
hands off the stick, to get a map, or sunglasses, and it will stay in
whatever attitude I had it. Also nice in steeper turns with little stick
pressure.

The only time I really have to pay attention to stability and rudder use, is
when I haul the canoe with Wayne's canoe loader. I am getting used to that
now, but it can be a little unnerving in turbulence.

I also really like not having to adjust my elevator trim every time I change
flap or throttle setting like in some airplanes.

I guess all airplanes are a little different, and there are compromises, but
sometimes it is just preference or what you are used to.
