trasnsition. Something as seemingly minor as changing from an APC
"Pattern" prop to an E series can make a huge difference. Going electric
will make you truely believe in experimenting with different props.</FONT></DIV>

<DIV><FONT size=2>Any higher performance engine will have higher maintenance

part of the deal.</FONT></DIV>

<DIV><FONT size=2>OS FS and Magnum RFS 4-strokes are great for
reliability. YS gives more power for the same displacement. Getting
that extra power comes at a price... and its not just the sticker when you buy
the engine. You can "detune" the engine using lower nitro and not asking
it to produce the same power and increase the time between needing valve
adjustment or other maintenance... but then you may as well have gotten the OS
or Magnum.</FONT></DIV>

<DIV> In the last 3 years I've gone from YS DZ140 to OS 160 back to
a YS DZ160 and now AXI Electric. I've pretty much decided to stay E at
this point as things are going pretty well at this point. As far as what I
think about YS. I think if your going IC then for my money YS is the best.
They are far from perfect but when they work they are impressive. I've come to
think of them as high performance engines on a race car. They are pushing the
limits and they are going to have expected failures. Just as a high
performance Electric setup does. Its just part of the deal. YS engines are
awesome performers. When I had the OS I always felt that I was leaving
something on the table from a performance standpoint. But hey its just my
opinion.</DIV>

<DIV>I'm losing sleep trying to determine whether to put a YS in the
Integral I ordered or if I should stick to the OS140.</DIV>
<DIV> </DIV>
<DIV>The last time I ran YS was 8 years ago. I got frustrated with the
various maintenance, gaskets, diaphrams, rings, bearings, falme outs and
header failures that seemed to be a natural part of the YS experience. I
switched to OS and never had a reliability problem again.</DIV>
<DIV> </DIV>
<DIV>However, I flew a 160 powered aircraft recently and imediately noticed
the difference in speed control, torque etc that makes the YS the easier
engine to fly the sequences.</DIV>
<DIV> </DIV>
<DIV>What's the typical maintenece on a modern YS?</DIV>
<DIV> </DIV>
<DIV>Flights per plug, flights between valve adjustment, pump
adjustments/replacements, bearings, gaskets etc.</DIV>
<DIV> </DIV>
<DIV>And what's the cost of the 170?</DIV>
<DIV> </DIV>
<DIV>Any advice will be welcomed.</DIV>
