haven't seen an RCSE post since about 2:00pm.
Was there anything of interest?

I'm tired, and my brain has stopped working.
How do I connect a 5 cell pack that has 4 cells in a standard "Flat Pack"
configuration, with a 5th cell sticking straight out from the midpoint of
the last cell (pointing into the nose).
Is there a website that would illustrate this? I'm simply
I've got a GP Spirit 100 in the box that I plan to build this summer. Are
there any web sites out there that have hints/tips/bashing instructions to
make this a better plane?

Somewhere around the beginning of the year, I set out to do some
systems design, analysis, and optimization work on the F3J/B toys.
The first order of business was to do some airfoil analysis and
design. For familiarization and training, I decided to attack HLG.
I broke down the HLG design into
I'm finally slowing down, and staying in one place for a couple of days...
Did a quick scan of the legion of email on RCSE from the past couple of
weeks, and have some thoughts to pass on. First is on the mecca of
hand launch, the soiree at Poway last weekend. The second is on the
launch
Sorry about the very delayed response on this one, I've been
away from my email for quite some time now.
The now old launch height thread kind of reminds me of the
early threads on DS. I remember the initial posts that I got in
response to my first DS posts. Most of which had comments
that
There are many ways to install a spoiler in wings. Most that I have use
1" trailing edge stock you pick up at a hobby shop. You need enough to
cover a span about 3 or 4 ribs worth. I like my spoilers to stand up 90
deg. To get this you need to put a 1/4" X 1/4" peace of balsa behind the
spar.
Hmmm...

Somehow I think you got taken... UNLESS there is another explanation for
this curiously composed email. Next time, you might want to try using
punctuation, capitalization and grammar checker.
Well, I un-soldered
my fingers from the battery, stepped back and thought about it a little
more. Turns out my polarity diagram was right, I just didn't follow it :-)
It's close to 3 AM,
and finally, my plane is ready to practice at Torrey this afternoon. Got

Wing loading formula - the nonscientific way - no need to use
a Cray or similar :-)!
Basically it is just weight through wing area -
if the wing is tapered, you have to
project a root rib on the centre line
(if the wing doesn't pass
right through, that is):
For a rectangular wing area is
Bummer, I wasted a wish cuz I come to find out that there are so many good
things to say about the Stratos (From ShredAir) that it will easily fill the
RC Soaring Digest article.
This is a truly competiton designed sailplane. While it looks like just
another Euro-Clone V tailed Moldy
Think about it, you are still using 10 pounds of pull from the rubber, but
now it has to lift up 2.5 times as much rubber 2.5 times higher (center of
mass of rubber). That's where a lot of the lifting power is being lost.

fractional difference in calculated launch height is
With my GL, I started "highstarting" with a Dynaflite 2M
Upstart and then graduated to an NSP Standard Hi-start
Upstart has 30' of latex and 200' of line with a tension
of 7 pounds. The Hi-start has 100' of latex and 400'

I spent 6.5 hours today flying a new Stratos SL. The performance of this F3J
sailplane was astonishing. From the first flight at 12:30 PM to the last
flight at 6:30 PM this plane would not come down until I asked kindly and
then it always landed within 5 ft of me. The stability of the landing

was just getting ready to x off line when your message came up.

You're right. My numbers were off if one had to buy everything new and used
Ultracote instead of tape. Our club bought several Boomerangs at the same
time so we all got a small price break. That estimate was secondary to to
main point of my reply to the original. From the perspective of someone
Flew my #1 plane for the 2000 world championships today!
It was one of the three identical PSYKOS I am taking to Greece,
...and it is the stuff of dreams. A real planform! Actual computer-

It's red-white and blue molded, blended
I look forward to seeing the launches and loops at Visalia this year. You
always amaze me.
