Sorry about the mis-information. I dug a book on glider instruction to
verify that the stall-spin condition I referred to occurs from skids, 
not slips. The "under the bottom" on final is the situation I was trying
to reference.

As for 40 degree flaps blanking the tail, I was told that by 2 instructors
(I flew with with 5 instructors in 4 years before I got my ticket...) that
this condition occurred and was the reason for limiting 152's to 30 degrees
max. I can't find anything in the manuals either but I'll keep looking.

I was alos told that a 150 cannot climb with 40 degrees flaps down. I have
had the experiance of having the flaps go to full down on takeoff. The limit
switches were bad and I had set the flaps for 10 degrees for short field
takeoff. The instr. was with me (he's not the one that warned me) and noticed
that we weren't climbing- from looking outside by the way. We had enough
altitude to do a 180 and land on the same runway. We were weren't climbing
well at all, but we were climbing. It was fairly close to "std day" conditions
so I cannot account for it due to den alt. 

I've tended to believe all of my instructors, but they do differ a lot on
theory and practice. The gent who rents his 150 to me these days has been
flying more than 40 years, and refuses to use more than 20 degrees flaps
on approach (his tires...) and instructed me to (biennial) use long low
approaches with power. He called my high, gliding, incremental flap 
patterns "Aeronca landings". So now I end up with a high approach and only
20 degrees flaps and usually have to slip the plane a lot to get it down.
I may not appear too proficient but it sure is fun!
