<DIV>This is very interesting. I have always ran YS motors, and have just
recently started flying Webras..... when Merle Hyde suggested his "A" Mount, I
bought it, but questioned the lack of a nose ring.....I haven't been able to
tell a difference, but was interested in your findings. </DIV>
<DIV>Thanks for the info!</DIV>

<DIV><SPAN class=883230603-02012004> I
have a video of a YS/hydemount combo on a test rig "snaking" a little as
it spooled up to full rpm. Interestingly enough the spinner was holding its
position pretty well and the rear of the engine was gently gyrating.
</SPAN></DIV>
<DIV><SPAN class=883230603-02012004></SPAN> </DIV>
<DIV><SPAN class=883230603-02012004>In the air the I have tried blipping
the gas and a few other things with both types of engines. I was very
interested in seeing if the lack of nose ring would make any difference.
I ran the Mintor 1.70 with and without a nose -ring. I could not tell any
difference in flight behavior.</SPAN></DIV>
<DIV><SPAN class=883230603-02012004></SPAN> </DIV>
<DIV><SPAN class=883230603-02012004>What I did see was lower battery
consumption without a nose-ring. I think that it was due to the lack of
the engine touching the sides and passing on vibration near the
cowl.</SPAN></DIV>
<DIV><SPAN class=883230603-02012004></SPAN> </DIV>
<DIV><SPAN class=883230603-02012004>A very loose nose-ring is probably a
solution to catching extreme load gyrations and gyroscopic twisting
of the prop disc on heading changes. We tend to have tight nose-rings
that somewhat defeat the point of having a soft-mount in the first
place. </SPAN></DIV>

<DIV>Have you experienced any "searching" by these motors on this

<DIV><SPAN class=159125700-02012004>Nat, That's a big question.
</SPAN></DIV>
<DIV><SPAN class=159125700-02012004></SPAN> </DIV>
<DIV><SPAN class=159125700-02012004>Just got back to our hotel after a day
at the beach - actually the flying field. My wife went shopping and I went
flying. 181 is now my magic number of months that I have flown an RC plane
at least once in a month. Feels good to get it done on 1/1/2004
and I just know that there is bound to be cold weather waiting for us
up north.</SPAN></DIV>
<DIV><SPAN class=159125700-02012004></SPAN> </DIV>
<DIV><SPAN class=159125700-02012004>I am running with "A"
type Hydemounts on all of my big (1.40-1.70) 2-c's. Some of which are
actually stiffer than usual. Anything I have flown without an iso-mount has
shown high frequency vibration damage such as horn-bolts snapping etc. With
the big four-bangers we also had to deal with a lot of "shake" dampening as
well. The 2-c's run a lot smoother and as such shake a lot less. So far I
have found that 2-c's present less problems in the area of isolation. They
are definitely smoother at full rpm. At very low rpm they will bump around
as much as any other engine of that size.</SPAN></DIV>
<DIV><SPAN class=159125700-02012004></SPAN> </DIV>
<DIV><SPAN class=159125700-02012004>Hope that answers your
question.</SPAN></DIV>
<DIV><SPAN class=159125700-02012004></SPAN> </DIV>
<DIV><SPAN class=159125700-02012004>Off to the new air and space museum in
near Dulles VA tomorrow.</SPAN></DIV>

<DIV>Eric you have flown far more airplanes than than most. I, for one,
would appreciate your opinion regarding selection of motor mounts. Do 2
strokes present more problems in getting good top and bottom isolalation
? Happy New Year

you made it into 2004. FAI pilots will be flying P-05 and maybe unknowns
and F-05. Masters pilots will probably be flying their schedule for the
last time. Intermediate pilots will still be exiting down-wind, but
may get a snap to do in 2005. A lot depends upon how progressive our AMA
committee sees our future.</SPAN></SPAN></DIV>

a force in pattern but the 4-c's will fight back with cubes!. Electric
power will continue to tempt us in in a most tantalizingly
expensive manner. New pattern plane designs will help us fly better
and make it as hard as ever for judges to separate us. New servos will
give us more rudder power and better resolution to amplify our skills and
of course our errors.</SPAN></SPAN></DIV>
