<DIV><FONT face=Arial size=2>A comment about "mileage" is in order. I
don't want to upset anyone because they may use a different prop/throttle
management technique. My style is a slower-paced presentation, although I
tend to stay out near 150 or so, and the three blade is a very efficient setup
in my package. It has very good braking, yet accellerates well - - - for
me.</FONT></DIV>
<DIV><FONT face=Arial size=2> Other motors have different
mileage, and different techniques of throttle management, so perhaps it wasn't
fair to make the mileage comparison. The DZ that I observed, however,
seemed to use quite a bit MORE 30% Heli Cool Power than my 15% Cool Power, so I
thought I should include that in the spreadsheet.</FONT></DIV>

<DIV><FONT face=Arial color=#0000ff size=2><SPAN
class=560521004-16092004> Interesting comparison. Some people will always
favor the 4-stroke because they have a different feel but it's interesting to
see the fuel consumption. I was worried about this. Up to now the biggest
motor I have been flying is an OS .61 Long Stroke. It eats fuel at a pretty
good rate. From what you're showing, it looks like the 1.60 will actually get
better mileage. I'm assuming this is because you don't need to fly it at full
throttle all the time. I'm surprised at the big difference between the 1.60
and the YS. My small 4-strokes (.40 - .46) get much better mileage than their
2-stroke equivalents. I have an Enya .46 4-stroke in an Ace 4-40 that flies
well over 10 minutes on a 6oz. tank whereas a .40 2-stroke would need at least
an 8oz. tank. If you can get 8 minutes out of less than 7oz. of fuel with the
1.60, you must be doing something right. It looks like I should be happy with
my new motor next season...</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2>Had some questions from the last contest, so
decided to do a little spreadsheet. Just comparing operation of the YS
1.40 DZ to the OS 1.60 (performance being roughly equal, according to
feedback I've received from observers of my setup).</FONT></DIV>
