If you can't let go of the stick without starting to climb or descend, you
need it. This is the thing I always had trouble with in sims, especially
with a cheap stick that didn't have trim on it.

Some aircraft like a 152, you could go a long time without trimming.
It's quite easy to hold pitch without even trying. Others are a
bit more demanding. I got to fly a Republic Seabee the other day.
Believe me, you want to retrim that puppy. It takes a lot of force
to hold her when she's out of trim. Other aircraft it's a convenience.

And I can tell you, I got used to the electric trim in the Navion
real fast.
