Real pilots don't need no stinking flaps.  For fun, find some

Paul is right, good practice for when the electrics go out.

I learned to fly in a Schwitzer 2-32 glider.  Spoilers are used to

control

rate of decent and sometimes they are not enough. Slips are

required at

times,  plus slips are just plain FUN. BTHW I would like to use

slips more

often in a C150, but they are not approved with full flaps. Most

of the time

I use full flaps, so no slips most of the time.

Do it anyway Monty at altitude so you can become familiar with how it
behaves. The 172 bucks a bit more with full flaps than the 182. Never
tried it in a 150.

Monty must have one of those "modern" C150s.  All mine have 40 deg
flaps, which is really nice when you are trying to get into a very short
field. (Guess how I know)   But not quite so nice if you attempt a
go-around with full flaps (40deg).   The pitch up is amazing with full
power!  So if 'full flaps' is 30 deg, like the later C150s, I agree -

use 'em.

For the 40 deg models, reserve the last 10 deg for when you are sure
you really want it, cause the thing will barely climb with 40 deg flaps
and the pitchup from trimmed/idle/60 mph  to full power is impressive.

Apparently the huge flaps can blank the tail in a slip, leading to
exciting things happening too close to the ground.

My instructor pointed this out to me: the 150 stall speed between 20 and
40 degrees of flaps is only *1* MPH!  And for that go-around, those
extra 20 degrees hurt enormously.  That's why he teaches everyone to
only use 20 degrees max.  I learned in a 172 but recently got checked
out in the 150; that's when I found out.  Makes perfect sense to me.  He
also said the 150 just barely will climb with 40 degrees of flaps; if it
is near fully loaded, it won't climb at all!

All true, but sometimes you need the extra drag, like in an engine failure
landing in a short field, and you need to drop in steeply to avoid an
overshoot.  My normal C150 landing use 20 deg, but I practice with
40 occasionally.
