Hi John; No, it wasn't Udet.

Good try, tho'

And I heard the record had been broken more recently. I was told it was a woman, but not Patty Wagstaff, so I'm glad to be better informed on the subject.

I wouldn't fly a plane that can't complete an outside loop. Even my Aeronca Champ would do it, given enough altitude and speed at the entrance, and it has a flat-bottom wing!

AstroHog; Try a larger circle (you'll need lots of altitude). The larger circle will allow you to build up enough speed on the downside to climb back up. Also, the larger circle will keep the angle of attack small, and avoid the "roll-out."

On the otherhand, I suspect the records were set in airplanes that could do very small loops at slow speed, using lots of power to complete, but not exposing the pilot to as much negative Gs as large, fast ones.

Would you believe the old record was over 100? Oh, my aching eardrums!
