<DIV>Ed,</DIV>
<DIV> </DIV>
<DIV>I took a quick look at the 2003 Nationals results for Masters and
FAI. Looks like 1st place in Masters was a 2C, and 5 of the top 10 in
Masters were 2Cs. FAI was won by a YS4C, and 4 of the top ten were
2Cs. If memory serves me correctly, all 6 of the 4C fliers are sponsored
by YS and one of the 2C fliers might be sponsored.</DIV>
<DIV> </DIV>
<DIV>I've been flying FAI for 5 seasons and used 3 different 2C setups and
don't feel that I am missing out on a warm fuzzy feeling. Maybe that is
because my 2C is cheaper, vibrates less, requires less maintenance, and
is more reliable than a 4C (parts is parts). And I've not yet found a
140DZ or 160DZ (w/ 30% nitro) with enough power to spin the prop I am
running on my 2C (w/ 20% nitro) - and yes, my 2C has plenty of torque and a
linear throttle. Oh yes, it is also quieter and uses less fuel per
flight than a 140/160DZ.</DIV>
<DIV> </DIV>
<DIV>4Cs became very popular in pattern when the rules changed to allow a
4C to have 2x the displacement of the 2C and YS very successfully exploited
that rule change and designed and produced some very powerful competition
4Cs. Had it not been for that rule change, I doubt the 4C would
have ever even become popular in pattern. As the current rules do not
give an advantage to a 2C or 4C, the 2Cs will return to dominance - unless
the electrics take over first.</DIV>
<DIV> </DIV>
<DIV>But then again, as others have pointed out, some pattern guys just like
to buy the most expensive toys and spend endless hours
tinkering..............</DIV>

<DIV>Yamada the company that makes YS motors is dedicated to the support of
F3A (pattern on the international scene).</DIV>
<DIV> </DIV>
<DIV>The main reason YS motors dominate is because of their performance. The
problem is there are limited sizes of motors....The YS 160DZ is now the
biggest motor produced. It can fly about a 13lb plane and still have enough
power to hover it. So a 100" IMAC model just isn't in the realm of the YS
motor. If YS made a 100cc gas motor man alive would everybody want one. Mr.
Yamada knows how to make Horsepower!</DIV>
<DIV> </DIV>
<DIV>It is my understanding that Mr. Yamada used to work at Honda back in
the old days when the small Honda motors were revolutionary in motor cycles,
smaller compact cars and so on.</DIV>
<DIV> </DIV>
<DIV>As for Fun fly planes the YS 63 is probably the ultimate power plant
for any 46 sized model. Its got tremendous power and without a weight
problem. The Flip 3D's, Madness, and other 3D funfly planes like the Hover
Cobra, Magic, Razor, and UCD 46 are perfect models for the 63</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>I have seen YS 140Sport,s and 140L's run scale models up to 15-17lbs
and depending on the plane it will fly them but you will not have the extra
power.</DIV>
<DIV> </DIV>
<DIV>Now Heli's YS has a good foothold with the different motors they offer
including a 91 4stroke Heli motor.</DIV>
<DIV> </DIV>
<DIV>YS engines are probably the best model motors produced today. </DIV>
<DIV> </DIV>
<DIV>I can choose any motor I want to run and I choose the YS motors above
others because of the quality and performance. Here in recent years the
2cycle motors have taken a foothold in the lower classes of pattern flying.
They make tons of power and tend to give a less experienced flyer a
warm fuzzy feeling. They will make good power on 15% nitro and even not
setup correctly they will make big power....I have run them from the OS EFI,
to the Webra with mixture control carbs. With other in between.</DIV>
<DIV> </DIV>
<DIV>I prefer the YS 4 strokes because they perform better. So the main
reason YS dominates Pattern and not other forms is because they focus on
pattern models and pattern type setups. Because of this focus the motors do
the job the best....The bigger models just will have to wait for YS to
produce bigger motors if ever.</DIV>

<DIV> Ok, time for another newbie question: it seems to me
from the discussion and contest results and a few copies of the K factor
that Kane gave me at the D4 contest last year that pattern pilots prefer
YS engines, yet YS engines don't seem to dominate in other kinds of
flying(IMAC, scale, fun fly, etc). Um, why?</DIV>
