Intruder is correct.
Heres something to try at home:
Go out and tie some lead to the tail of your cessna. Just enough so that the cg is behind the centre of lift. Now wind in a bunch of forward trim and takeoff.
Surprise! It flys - and maybe even lifts off a knot or two early. Now if you are still alive wind the trim back as you accelerate in order to keep the nose down. Thats right - back. Get yourself up to a nice safe altitude if you can for the next bit. Trim the aircraft for level flight. Now reduce power slightly and do not make any pitch inputs. Observe the nose rising as speed reduces. And as the nose rises speed reduces more, causing the nose to rise until...stall! But don't worry; plenty of height to recover. Don't cheat by making any pitch inputs yet! Now as the nose drops observe the speed increase. And observe the tendency for the nose to keep pitching down as speed increases. Try and recover. You'll need to be very hands on.
And that is why all commercially produced, conventional aircraft with ordinary cambered wings always have an allowable cg range that is in front of the centre of lift. Hence always a downforce on the elevator when in stable flight (ie not maneuvering) throughout the allowable flight envelope.
On a canard the reverse is true. Always an upforce when in stable flight . This gives them the advantage of no trim drag. Why aren't they more popular? I don't know.
PS - Don't really try this!
