Let's see what is it that you are experiencing. Before flight with the
plane sitting on level ground (at least as much as you can tell). Is the
ball centered? As you taxi and make small heading changes, does the ball
move freely in the raceway? In the practice area. Slow to 60 Kts, pitch
up and add full power, maintain 60 kts. You should immediately notice the
ball go right and you will need right rudder to center the ball. Keep the
plane from changing heading. Be sure to keep the wings level. Now notice
as you enter into a left turn, you DO NOT need to step on the left rudder
(you only maintain enough left rudder pressure to keep slack out of the
cable system) until you have released all the pressure from the right
rudder, then as you increase bank further you can add left rudder. In fact
you MIGHT not need left rudder at all. Keep the ball centered all the time.
Is that what you are seeing?

Now, In a glide situation, things should be more symmetrical. Lower the
nose, reduce power to say 1200 rpm, maintain 60 kts. As you bank right and
left the rudder pressures required to keep the ball centered each way should
be about the same. Do you see this effect? Please report if you know, or
try it the next time you go out.

Except when the control system is misrigged like a plane I flew
recently. In order to get a coordinated turn, I had to give "top"
rudder in a turn. That's wrong.

Is that the one in which I suggested a broken rudder bar spring?
Anything come of that?

Yeah, I think so. Another person also emailed me private and said the
same.

The chief pilot and other instructors at the FBO got an email from me.
Never heard anything back. Maybe they checked it out and decided I was
wrong; or maybe I found a problem and they don't want to comment on it
in a traceable way. I think I'll switch to their 172, rather than fly
that 150.

On the other hand maybe they have fixed it and I just don't know about
it.
