This American design from the 1930's also had leading edge slots! One of a kind for weird modelers?

STUKA DIVE BOMER

Yikes! Flicka, looking at that sketch, I think the aileron and the wing are acting as a two element airfoil. That might explain why this design is so stable at low speed, it's producing just gobs of lift. I'll bet that when you do try them as flaperons, the McCessna will be able to fly so slow it'll look like it's standing still.

Just finishing my next weird model. Hope this unorthodox model flies with electric power? 100 years and counting!

I gotta see that one fly!!!
What the dimensions, etc?
What is the construction and covering out of???

-Q.

Hi,

According to Reynolds, the slower we fly the thicker the boundary layer becomes.
That's why the Junker's type ailerons should be more effective with models flying slow.

It took a post from Sweden to explain my unorthodox designing. Adam, "tack"!

Do keep in mind that the separate aileron installation is going to be heavier (up to twice when using solid trailing edges) than the conventional aileron installation. What you are doing is duplicating the trailing edge structure twice (kinda) (always use weasel words if necessary).

Loss of effeciveness with an aileron that was reasonablely sized to start with can always be made up by a slight increase in deflection or just holding in a deflection for a longer time. Most airplanes, expecially man carrying ones, fly upright, level, for long periods of time. The deflection of an aileron is a rare occurance and for just a few degrees at a time. In that respect a conventional integrated aileron is just as good.

It is difficult to sing the praises of the McCessna installation unless you have models with and without that aileron installation. Then a reasonable statement can be made as to the gains or losses of that design.

It is interesting that in a design where the airplane's good aileron response is really a prime factor, namely the aerobatic airplanes, that the conventional aileron is always chosen.

In all of the airplanes I have worked on in which flap aerodynamic effectiveness was given prime importance and structure had to produce the design regardless of difficulty the conventional double to triple slatted flap was always chosen, not the Junkers type of flap.

In initial design of an airplane you have to look at what is most important for your particular use and see if the trade offs are worth it.

Ben,
You have got a point since the risk of extra weight and the complexity of assembly may counteract the goal, especially with very small models.
And since most R/C radios today have dual-rate facility, the R/C pilot may choose larger throws angles during slower flights and smaller ones when flying fast.
Anyway, it may be an interesting area to explore for those who like to experiment…

Flicka5,
"Flicka" means "girl" in Swedish, are you a "Flicka" from Sweden?!
As for your "tack" I should say "välkommen"!

Vänliga hälsningar,

You still have not answered my question from another posting? What year was this picture taken?

Adam: flicka is my kat's name and so named because she loves Lutfisk. I like your web page. Are all those models in your gallery yours?

Hi!

That's a funny name for a cat (kat).
No, unfortunately the models shown are not mine, I've just taken some pictures during several shows in Sweden and other places in Europe.
I'm not a scale modeller, but I like to see them…
I've just flown some trainer models so far.

And thanks for appreciating my site, I'm also learning how to control HTML code…

Cheers,

On the photo, beats me, I was but a small child when it was taken, actually maylbe not a child yet. I would guess in the late 30's to very early 40's.

I can't give the exact date but I would bet that it is before June 1, 1937. If I am not mistaken, the plane is a Piper J-2.

Adam: since my kat named Flicka loves Lutfisk, does that make her Swedish or just hungry?

Ben: since you are from Purdue, thought you would know the history of Amelia Earhart at Purdue, hence my question.

Lightfoot: the Earhart pic. at Purdue must be before '37 because isn't that the year she disappeared? The guy in the black suit on right along with Earhart and others attached was the Dean/Pres. of PU during the 30's.

Well, I guess that makes her just hungry…
A "real" Swede enjoys the taste of "surströmming" which may be translated as "fermented Baltic herring".
Have you ever tasted it? That's delicious…

Hälsningar/Cheers,

Adam: Is that fermented herring like "Sill" (pickeled herring)that we eat with lots of "Glogg" inbetween. We don't let the kat get into the Glogg because it makes her funny! Picture is of my relative greeting me in Stockholm!

My reasoning behind the date, June 1, 1937, was simple:

Amelia Earhart was in the picture.

Amelia Earhart took off on her final adventure on June 1, 1937 never to be seen again in the U.S.

The picture had to be taken prior to June 1, 1937.

Just simple logic, after recognizing Amelia Earhart of course.

Lightfoot: your reasoning makes sense to me. Earhart image at Purdue airport with PU football player attached

Hej.

Oh no, surströmming is much more exciting, though pickled sill is also tasty.
There's only one drawback (as with everything), one needs to be really tough to keep breathing after opening the can… you have to be a "real" Norrlander to stand it...
Kidding aside:
I have to advise that very few appreciate the smell of the fermented herring. One may say that it tastes better than it smells…

I agree, glögg is not good for a kat even though she is a Flicka.

Hälsningar/Cheers,

Hi again,

I guess I just forgot to comment the picture you attached showing your relative greeting you in Stockholm.
Your picture is very interesting because we seldom see "real" Vikings in Scandinavian nowadays.
They have probably extinguished themselves since they rather died young in combat than old and sick at home.
By dying in combat they would join their gods in Valhalla…

For more detailed descriptions you might consider reading their history at:

Adam: confession time as I took the image of the Viking warrior "axeually" in Oslo, dockside. However, had been in Stockholm a few days before so close enough? See real attached image from Stockholm. Have some knowledge of the Viking exploits as have seen all the blond/blue eyed people in St. Petersburg and the Viking fortress guarding the Russian harbor there. Also know that the Vikings invaded the Italian peninsula but sacked the wrong city thinking it was Rome. Also, everyone knows that Leif Erikson discovered N. America way before Columbus and the only failure was their plundering of Paris but not burning it to the ground! They were a tough bunch but finally got religion to mend their ways and stay home.

Hi,

Your picture shows a replica of a Viking boat built by some enthusiasts here in Sweden.
Unlike the original, this one is motor powered and is often used to transport tourists around the Stockholm's archipelago.
I'm not sure whether it 's exactly like the vessels used by Leif Ericson though…
A Viking boat replica was built and sailed down to Seville (Spain) where she sunk during Mediterranean's hard weather, just before she reached the Spanish arbour (all onboard were rescued).
That caused some people to wonder whether the Viking sailboats were seaworthy enough to cross the rough waters of the North Atlantic…

Cheers,

Adam: their ships must have been very seaworthy as no other explanation as to how my ancestors ended up in N. America a long time before Columbus. Swedish P36 attached:
