80's I was flying an MK Arrow copy running the traditional 11-7 1/2 Rev-Up (couldn't
get a D-W) on a piped OS 61-VF tuned conservatively to between 13500 – 14000 RPM
on the ground. One of the clubs I belonged to closed for a year due to a noise
complaint. When it 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 performance, burned about half the fuel and a glow plug would last half
the summer. <o:p></o:p></span></font></span></p>

for a bit of 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.)</span></font><font color=black><span style='color:black;

style='font-size:12.0pt;color:black'>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.</span></font><font color=black><span style='color:black;

style='font-size:12.0pt;color:black'>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 US 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.</span></font><font

<div id=yiv1158923941>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>
