Kaos mentioned stepping on the ball which is, as I mentioned earlier, an important element of the maneuver. I thought I'd add that if your CFI covers the instruments, there won't be a ball to look at so make sure you watch for the subtle movements (yawing) of the spinner in relation to the horizon and correct them with...rudder.

Also, to clarify, I think Kaos meant that the stalling speed could be as high as 90 kts in a clean config. It's been a while since I've flown a Cessna but 90 kts seems kind of high in a clean config and 45 degrees bank. Perhaps that may be more accurate for 60 degrees bank.

Which if you're comfortable, may not be a bad idea to try (WITH FLAPS)! If you can get good at controlling your altitude in a 50-60 degree bank, 45 will be a lot easier! Don't try it as a solo student pilot. Ask your instructor to demonstrate a few at 60 degrees and then decide if you'd like to try one. A 60 degree bank turn is not required training for the Private but it is a very effective learning tool. You're instructor should already realize the importance of teaching or at least demonstrating maneuvers above and beyond what is required. Teaching only the bare minimums is not fair to the student.
