2100 is for when you're level (i.e. before you're abeam the numbers) and
trimming the airplane. Once you're abeam the numbers, you bring the power
back to something that gives you the rate of descent you'd like (and where
the previous posters point holds true... do get too fussy, look out thte
window at the airplane entering the pattern on an extended base or a long
final), put in your flaps, and slow to approach speed. Also keep in mind
that the actual power setting may vary from airplane to airplane.

Good luck,

I have to try your method. Maybe I can get my pattern flying without
'thinking' at all. Right now it is semi-smooth but completely not
mindless.

In a Warrior-II, 152 or 172P with just an instructor and a student,
setting 2100 RPM on downwind, and trimming for hands off flight seems to
set the airplane up for a normal approach speed when using 20-deg of
flaps, and the short-field approach speed with 30-deg of flaps.

Are you sure about the RPM? The method I've been taught is
drop the RPM to 1600-1700 (weight depending) when abeam the
numbers and throw in one notch flaps and pitch for 90 KIAS.
On base, 2 notches of flaps and pitch for 80 KIAS
and on final 3 notches and pitch for 70 KIAS. At 2100 RPM,
I'd still a few hundred feet off the ground.
