As far as History of sound and turnaround. Jim has it pretty much
straight. The noise issue was brought up well before turnaround was
introduced. When the noise limits were introduced we started going to
larger props and soft mounts. We were still using the short stroke high
revving engines. I switched from 11x7's to DW 11 x 9 W with a longer
pipe. Same performance, same speed but quieter. My first soft
mounts were hand made. Plates with vinyl grommets that mounted to the
rails in my <st1:City w:st="on"><st1:place w:st="on">Atlanta</st1:place></st1:City>'s.
Dean Pappas gave me the design. Next came the long strokes with even
larger props and even quieter. The long strokes made the switch to
turnaround easier. <br>

reopened as a recreational airpark with sound restrictions (100 db @ 3M) I went
out foe a check before changing anything. I was making over 105 db and during
the check I observed that both the db and tachometer needles moved together
when throttling up and down. Adding a soft mount and lengthening the pipe
around 2" reduced the sound 10 db turning a 12-9 prop. I actually gained

history now. When the turnaround system was added, were't the pattern
folks flying unmuffled (or barely muffled) 2-strokes with high noise levels,
not the now (relatigvely quiet) well muffled 4 strokes? (to say nothing
of the current generation electrics?) There may be some interconnection
/correlation here. Just asking, Dave, not quarreling at all. I've
flown pattern before it was called pattern, when you made up your own sequence,
and did only those maneuvers you wanted to do. Now of coursw, we have a
well established turnaround pattern. (Which, by the way, I prefer.)<o:p></o:p></span></font></p>

style='font-size:12.0pt'>Dave L mentioned the "noise footprint",
but I am not sure that is a major reason (maybe it was?) that we went to
turnaround. I was not heavily involved in pattern at that time. However,
"noise footprint" can be divided into two parts, "noise"
and "footprint". The fact that, as Dave mentioned, some sites in
the NE are starting to fly pattern events again may be due more to the noise
level than the overall flight footprint. So, the turnaround aspect may not be
the saviour in this case as much as the noise reduction itself. Either way,
thanks can go to FAI because that is where the noise reduction
technology came from, and it filtered down to the AMA flyers. IMHO.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 color=black face="Times New Roman"><span
style='font-size:12.0pt'>All that aside, I have always felt, and expressed my
opinion, that the AMA rules and schedules should be geared towards what
is best for the sport of precision aerobatics IN THE USA. I don't think
we should pick schedules for any class, including Masters, with the major
concern of helping prepare our pilots for FAI. FAI is another class, and
if you think about that, here in the <st1:country-region w:st="on"><st1:place
w:st="on">US</st1:place></st1:country-region> it is almost two classes in
itself: Those that fly at national/world level, and those that don't. If someone
is really aspiring to fly at a world level, they will find the FAI class all
by themselves. The fact that we do fly the FAI class at all contests is,
IMHO, all we need to do to help them prepare for world level competitions.
There is no need for us to put an FAI flavor in the Masters sequence,
unless it will benefit pattern flying in general.<o:p></o:p></span></font></p>

<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3 color=black
face="Times New Roman"><span style='font-size:12.0pt'>As I recall, the ONLY
reason AMA is now flying turnaround is because F3A went to a turnaround
format. The "powersthatwere" were concerned that our team would not
have the relevant experience to compete on the world stage. This started a
process of conversion to turnaround by including the FAI pattern and then
expert turnaround in AMA pattern contests.<br>
The pendulum has now swung the other way where the AMA pattern community,
while overly committed to turnaround, rejects the patterns, rules and
concepts of the FAI.<br>
<br>
While I no longer see a need to use the current(or past schedule as we have
already done) F3A pattern as the Masters pattern, I believe it is important
to address whatever is new and challenging in the upcoming F3A patterns and
consider introducing similar elements into the Masters pattern.<br>
<br>
At the other end of the spectrum, I believe that the Sportsman class should
have the turnaround elements removed completely. Perhaps some of the center
maneuvers could be upgraded in difficulty at the same time. The sportsman
flyer needs more focus on learning the maneuvers and where to place them.
Making them fly the box simply insures that they aree not in position to do a
proper center maneuver. This is not intended as a first step in getting rid
of turnaround but rather creating a progression in the learning process.<br>
