<DIV><FONT size=2 face=Arial>Hi Guys,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Just thought I'd let everyone know what I've been
up to. I'm sure that most everyone thinks of me as the Blucor guy</FONT></DIV>
<DIV><FONT size=2 face=Arial>and I guess that's what I've become.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Well I decided that I would try to go a little
further and see what I could do with a little more sophistication and
hopefully</FONT></DIV>
<DIV><FONT size=2 face=Arial>somewhat conceal the obvious by a little paint, a
little rounding of the corners, a little fairing of the nose section (not
easy)</FONT></DIV>
<DIV><FONT size=2 face=Arial>maybe a canalyzer, pants, and a touch of
graphics.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>As many of you know, it's extremely difficult to
make paint stick to the mylar film on this stuff, so I decided I'd do a little
</FONT></DIV>
<DIV><FONT size=2 face=Arial>experimenting. We've been using an RC-56 type
adhesive for many of the necessary join operations which really does
stick</FONT></DIV>
<DIV><FONT size=2 face=Arial>to this stuff and being a white substance, I
decided to mix in some color and see how that would work. Well the first
exper-</FONT></DIV>
<DIV><FONT size=2 face=Arial>iment seemed to be pretty effective at 50% of each
so I decided to cut back to about 1/3rd glue and that was still not that
</FONT></DIV>
<DIV><FONT size=2 face=Arial>great, but I decided to use that ratio anyway.
The thing I noticed about this paint/glue mix was that even after a couple of
</FONT></DIV>
<DIV><FONT size=2 face=Arial>days of drying the thing still felt sticky. If you
picked up the plane you couldn't put the buggar down,.....kaaaaah. I
ended</FONT></DIV>
<DIV><FONT size=2 face=Arial>up painting up to a masked line, then painting a
different color up to the other side of the tape then pulling the tape and
filling</FONT></DIV>
<DIV><FONT size=2 face=Arial>the tape gap with film (monokote).</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>I decided to try something different as regards the
force arrangement. My experience thus far has seemed to indicate that
</FONT></DIV>
<DIV><FONT size=2 face=Arial>stuff with wheel pants (fixed gear) appears to
contribute to the dreaded pitch to the belly in K.E. so I decided that I would
</FONT></DIV>
<DIV><FONT size=2 face=Arial>attempt to address the anomoly by placing the
engine thrust line below the center line of the wing and act as an up
pendulum</FONT></DIV>
<DIV><FONT size=2 face=Arial>force pulling to the canopy.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The cheeks are just plastic spoons. There's one
under the chin, open at the front, for additional cooling and the leading
edges</FONT></DIV>
<DIV><FONT size=2 face=Arial>have straws, cut in half longitudinally, and glued
in place for a constant radius, stab included. The fin is cut as one piece
with </FONT></DIV>
<DIV><FONT size=2 face=Arial>the fuse side, so there's no seam where there would
normally be an attachment point. The T-Can, so far, is a press fit so that
</FONT></DIV>
<DIV><FONT size=2 face=Arial>adjustments can be made as needed, but it seems
pretty close, as when I hold it in my hand vertically and advance the
throttle</FONT></DIV>
<DIV><FONT size=2 face=Arial>it gives the sensation that it wants to hover
hands-off. None of my other stuff has done that.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>Well it's been done for a while and I've kinda been
waiting for a relatively calm day and today was IT, so I ambled off
around noon</FONT></DIV>
<DIV><FONT size=2 face=Arial>to the local field for a go. Did my range
check and eye-balled</FONT> <FONT size=2 face=Arial>the surfaces one last
time b/4 christening this new baby. The </FONT></DIV>
<DIV><FONT size=2 face=Arial>Soccer field grass was too high for take-off
so I advanced the throttle 'til I felt it getting light and gave it a soft toss
and it went up</FONT></DIV>
<DIV><FONT size=2 face=Arial>without a hitch. I'd done set-up a few weeks ago so
I just flew a few passes to see what trims were going to be required and I
</FONT></DIV>
<DIV><FONT size=2 face=Arial>ended up with one click of aileron (trim step rate
set at one) and that was it. I was not able to sense any roll or pitch couple in
</FONT></DIV>
<DIV><FONT size=2 face=Arial>both directions, so I was more than satisfied with
that, Buuuuuuuuuuut, for about the first 4 minutes or so I flew this thing very
</FONT></DIV>
<DIV><FONT size=2 face=Arial>slowly. Somewhere right around that time I think I
did a loop and coming down the back side of the loop the ailerons began to
</FONT></DIV>
<DIV><FONT size=2 face=Arial>flutter. I made a few more slow passes and tried a
Stall Turn. The thing fluttered on the downline with no throttle applied. This
</FONT></DIV>
<DIV><FONT size=2 face=Arial>thing flutters more than a Hummingbird. I'm
contemplating putting out some sugar-water for it !!!!!!</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>Now, I've built lots and lots of foamys and have
never had this problem before. What's even more aggravating is that I was
very</FONT></DIV>
<DIV><FONT size=2 face=Arial>meticulous about the surface joints on this bird
and can see nothing obvious that would differentiate this ship from all
those that</FONT></DIV>
<DIV><FONT size=2 face=Arial>have gone before.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>The only difference I can think of is that the
ailerons on this model are about 1/2 the area of my previous models as I was
intending</FONT></DIV>
<DIV><FONT size=2 face=Arial>this plane to have a more precise feel and less of
a 3D type craft. Of course the tip fences were not used B/4 and I'm wondering
if</FONT></DIV>
<DIV><FONT size=2 face=Arial>theres a build-up of turbulance at the outermost
portion of the surface? </FONT></DIV>
<DIV><FONT size=2 face=Arial>The flutter is a very high rate and if not checked
will undoubtedly become destructive.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Any solutions offered will be gratefully
received.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Thanks </FONT></DIV>
