Upon relooking at the diagram rather than the description, there
appears to be a 2of 4 going up and a 2of 4 coming back down. So no
knife edge corner.<br>
Note there is no downgrade for different radii. :)<br>

From the rulebook. 94-95. Actually describes both 1/2 roll and 1/4
roll<br>

From an AAM article in 1969. I never saw anyone fly this maneuver
in 1969 or for many years afterwards and it was optional. Picture
seems to be pretty clear that it was intended to be a rolling
loop, not a loop with a quick 1/2 roll every 90 degrees or some
such. Same article also refers to an FAI rolling circle, for which
I can find no definition.<br>

<p class="MsoNormal">Advanced and Masters are not our entry
classes and should not affect future participation. Those
new to pattern should begin in either Sportsman or
Intermediate depending on skill level. When a flyer feels he
is ready to move up, he will try flying the next class in
practice. If it is too difficult to even see a way to fly
that sequence reasonably, then that pilot was not ready to
move up and should stay in his current class another year
(or more). We do not lose people because they stayed in
their current class, we lose them because they moved up when
not ready and find they are outclassed without the vision,
coordination, time to practice (or name your reason) to be
competitive. Not competitive for winning, just competitive.
<br>
Both Masters and Advanced can, and probably will be, changed
next year. Any substantial problems can be addressed then.
Many have tested these sequences. All have have flown them
successfully, if not always happily. We can go on and on
about ugly maneuvers, difficulty levels and dislike of
change but that happens every cycle. <br>
<br>
Just for comparison here are Advanced and Masters from 20
years ago. Overall both appear somewhat easier than the
current sequences we are flying but not a lot. Total
KFactors are a bit lower. Also we are flying many of the
same maneuvers. I hope you noticed the knife edge top of the
cobra in masters. If you go back even further you can find a
two roll loop in the days before retracts...<br>
