It is understandable how flutter likely took apart the elevator and the

Now we have major failure of components in a jet airliner, Flight 587,

My wife and are going out along with Jerry Shape to PHX, we are all going

they get, up until right before the time of departure and they can get even
better, but I was not waiting that late. We are round

At first a good idea is ridiculed and maligned by those who don't
understand it, slowly it is accepted, so much so that finally it is
embraced as their own! Author unknown.

Bruce and Keith... you both recommended the SIG Ninja. It looks right along
the lines of what I'm looking for. I live in Oregon and the slope winds
here can be strong a lot of the time. With some extra ballast, how does
this plane handle strong winds? What about in times of light lift?
This did stiffen the surfaces to an acceptible level,
but there was still some flex right where the rod bends
45 or 90 degrees. An all carbon rod would be ideal!
Uh.. actually, a carbon rod would be horrible. Unidirectional
carbon has a puny shear modulus compared to steel, even aluminum.
These articles are indeed very interesting. The more I read,
the more it does not make sense. Could the tail coming off,
also cause the engines to fall off? And what about reports
that fire was seen coming out of an engine.
Here's one feasible scenario...
Vertical tail falls off.

Hey Jeff,
Glad to hear there may be another slope addict in the world. Have to say, though, that
your idea about having a bigger ship because
your slope lift is strong is not quite accurate. I fly a 70 oz, 44 wingspan
jet-looking sailplane at my home slope because the slope
lift is so dang
The Sig Nija is a good choice, but reenforce the fues behind the wing.
If you don't I guarantee it will break there.
I also like the Dynaflight Talon a fully built up ship and thus a bit
fragile, but a Fun ship.
I just moved back to San Diego after a 10 year absence, and I am almost
done

Good point, Lincoln. It depends on how nice your slopes (and especially
your landing zones) are. I've seen some slopes in pastures that look like
gold fairways; my usual slopes are rocky, brushy and brambly, and landings
can be thought of as arrival events. To this end, Zagis and wings are
A thought for a gloomy November day:
The sun is always shining, if you have sufficient altitude.

1) Two Meter Duck, $400 wired and trimmed with Airtronics 141 servos in the wings and Airtronics 102s in the fuselage. This sailplane was built by the designer, Troy Lawicki, and has full ballast attachment hardware. It was flown and place well at the Nationals twice. E-mail photo available. ***
No, it's not the Harry Potter movie (although it is quite good). I just
received my 2002 USA F3J Team T-shirt and the art work is the best ever.
I've been buying shirts like this for years - this one's a standout. The
art work even makes it easy to explain just what F3J is. My compliments
The pilots surely had no idea the tail came off, so differential power was
probably never thought of.

Unless it was going slowly wouldn't it be fairly stable? I have lost fins on
plank flying wings and it was only really a problem at low speed. The

Years ago, the Sig Ninja was my first ever slope plane. Epp foam had not yet
made the scene.
The plane flew well and looked good, but the fuselage was extremely weak.
Anything less than a perfect landing resulted in structural damage every
time. A couple of years later there was even an article
I think you're still not getting my point. I don't disagree that that's
the failure mode, it's just that my understanding is that fatigue isn't
supposed to be a problem with composite parts. If you know the history
of the aircraft, then you know if it's been overloaded and whether you
have to
I gave him a ring and it looks like he's gotten out of it. About all he
