Subject: FORSALE: Dumas 38 Scarab KV.


I have a Dumas 38 Scarab KV boat.  It is about 55 inches long. and is
totaly built by an experienced boat builder, but has never seen the
water.  It is set up for two engines and has two sets of running
hardware.  From Tower, this boat kit costs $230 and each running
hardware set costs $65.  The total kit price for this boat is $360.
I would like to sell it for $350.

Interested?  E-mail me.

This is correct.  Also the engine cannot have a pipe.  I heard somewhere

I am nearly finished with a 1/12 scale P-51D that I have scratch built from 
MAN plans.  BTW this kit is now avail by Miniture Aircraft with its rival Bf-
109 counterpart.  Kits run about $52 US.  As yet I have to find someone to 
fly with.  Big mistake is I have put to much time into this bird to let it 
go into combat I'm afraid.

I was thinking of buying a Sig Ninja as a second slope plane, my first
being a Bobcat that is a little under the weather
after a failed attempt at an inside loop.  Any pros or cons on this
kit?  Will it take regular servos?  Any other recommendations for a not-too-expensive intermediate slope plane?

Also, I noticed a plane, a Sig Samuri, in the shop that I could not find
in any 8-month-old ads or catalogs.  Is this a new plane?  Just wondering,
but it's a little over my price range.

My knowledge of French is minixcule, at best.  However, I think I 
understand that he has a Tucano kit, new in box, .40-.45 size, for
800 French Francs.  If I could convert to $US, I might be real

I spent 16 months building mine.  Not because it was hard to build, but
because I built three other planes at the same time.  :)
I don't have any complaints about the kit.  Great Planes makes the best
kits I've ever built.  Actually, there are some things I would change.
I'll explain those in a minute.
The one thing I've noticed with Great Planes kits is that they tend to
be heavy, so watch the weight.
I must admit that it was the best looking plane I've built yet.  Unfortunately,
it didn't survive the first flight.  I let someone more experienced than
me take it up for the first time.  Slight crosswind from the left.  It
comes of the ground and starts doing a perfect Dutch roll.  I start yelling
at the pilot, but before he can gain control it hits, wing tip first.
The wing was fine, but it tore of the cabin area of the fuselage.
After much soul searching and questioning the meaning of life, I determined
that the pilot pulled it off the ground too soon.  With the short tail
moment and the flat wing, it should be a snappy model.  It will be rebuilt,
but with a stronger structure holding the wing on.
So go for it.  It builds into a really nice looking plane.

I've watched some ninjas flying out at the ski slope near here and they
are certainly agile gliders.  You may find it is a bit of a handful and
they don't fly well without steady lift.

Well, true.. 

Perhaps theres something about Clark Y type foils that makes them
behave like flat plates with an aggle of attack? Perhaps the true 
angle of attack should be measured from the point where the wing 
produces no lift. So "zero" AoA isn't really zero?

Note that Bernoulli's priciple does apply to a flat plate - I'm sure
that if you stick it in a wind tunnel you'd see air above the plate 
move faster than that below when its at a positive AoA.

I heard an ugly rumor that Lubbock may not be the 93 Nats site after all,
apparently due to some problem with getting FAA permissions concerning use
of portions of active airport areas for the event. This seems to be
fourth-handed information, so it might be completely corrupted and
confused by now.

Does anyone know the actual facts?

Sure it does.

Even a flat airfoil exhibits lift at certain angles of attack, again because
the dynamic pressure of the air above the wing is lower than that below 
the wing.

(Of course, some part of my brain intuitively tells me that this lift is
equal to the action/reaction lift. There may be no "extra" Bernoulli
lift with symmetrical or flat airfoils.)

Well, you can use Bernoulli or Action/ Reaction to explain lift. Primarily,
they are different aspects of the same mechanism. For certain airfoil shapes,
there's some additional non-Reaction lift that takes place, too.

So you can't discard Bernoulli. A plane flies not only because it displaces
air downward (eg Action/Reaction) but also because of the lowered air pressure
above the wing (Bernoulli).

Doesn't that depend on lots of factors, like the air density & such?

We have 7 RR`s in our club. Most people build em stock and have a great 
time. I wanted to be different so I lengthend the tail 5 inches and put 
a V-tail on it. It suits my sense of asthetics better. I have A-R-E control
via the V-tail mixing. Three micro servos. Its really kool to do climbing 
rolling zooms off the high start or winch (yes we do winch them too! :) )
and the ailerons are very sensitive on the hill too ... can do most
anything you want with it.  The price is right but you also get what you
pay for ... the wood was of varying quality and hardness .. nothing tooo
terrible but some may need to be replaced.  A fun airplane and worth your

    Joe, I'll take a wild leap and assume you are from the Seattle area (you
have an ID with BOEING in it).  If you can contact someone who has built a
Dodgson Design flyers that work for Boeing, the only ones that I know for
sure are the Pugh family (Jim, Sandy, and their son Dave). The best thing
to keep in mind is make SURE when you glue, glass, or epoxy to the glass
fuse, that you have roughed up the surface and then cleaned (with acetone
or an equally obnoxious thinner.
  Anyone else have a better way? please post, I would be interested

I was planning to go to the Lubbock NATS as I have gone to 4 other NATS 
in the past.  BUT if they have it in Lawrenceville AGAIN!!! for the THIRD
TIME!!!  Then they can count me out.  Come on guys!!!  No one that I know 
of likes to go back to the same old place year after year after year....

Can someone PLEASE get OFFICIAL word that the nats are not in Lubbock????
Rumors only tend to make people irate!  I for one hope the rumor is
wrong.  I am tired of Lawrenceville!!!
