This is a replica of the fist Soviet all-metal plane ever. One of the first Soviet passenger planes. And the second plane designed by Andrey Nikolaevich Tupolev, a famous Soviet aircraft designer. He was my namesake, because my name is Andrey Nikolayevich too:) Just a beautiful and sophisticated plane! Finally, I’m a fan of old aircraft.
So, I had quite a bunch of good reasons to build a semi-replica…
Scale: 1:10. I used what I considered my traditional ceiling-ruler-adhesive-tape technology featuring plastic reinforcement. A sort of nano-project with the use of all so rare materials:)
Here are pics that show the building process. And a couple of comments.
I glued in reinforcement, which I had cut out of a plastic ruler, and lined the nose section with glass for equipment.
I made hings out of paperclips and pieces of aluminum cans.
Cocktail tubes serve as guides for pull rods.
The layer of glass in the nose section.
The frame and angle braces of the landing gear are made of bamboo sticks.
Horns are made from a plastic angle.
For a more true-to-life appearance I covered the wheels with thin plastic. Looks almost great!
Let the pilot test it. Looks like he feels well in there :)
My dummy engine.
Here is the three-cylinder "Donkey":).
This is the output product...
I all but forgot about this one..
Takeoff weight:
Wingspan: 1000 mm.
Length: 750 mm.
Weight: 515 g.
Well, what was the end of it? Strangely enough, it didn’t fly well enough. Yes, it is a high-wing plane built according to a classical scheme… What could have gone wrong? When I push on the throttle, it wing-rocks; release throttle – it goes smooth and steady. You can see that in the video. I did a 20% alignment, but it was ditto. Could that have been due to the beautiful and sophisticated landing gear? Those are actually two little wings getting into the prop stream. Haven’t quite figured it out so far. Any ideas? I’ll be happy to listen to my hobbymates’ advice and suggestions.
Let’s think it over and teach it to fly properly!
Thanks for reading.
Yours faithfully,

This is the translated version. You can read the original Russian article here.
I also made this aircraft model http://forum.rcdesign.ru/f82/thread282559.html # post3432736
this is the lack of vertical tail area.
the fact of the matter is that the focus is very much model vreperi vertical area, and such are destabilizatorami square (it's not only refers to the horizontal plane, but vertical).
and stabilizirueŝej vertical plane (focus models). I advise you to increase the area of Kiel at 15% or add podfûzelâžnyj comb.
this plane too suffered the disadvantage of roadholding.
a lack of impact not only on the course, but also on the roll resistance.
Good flights with a cut!
success!
I have noticed that not kapotirovala model, you moved the chassis forward.
and wheels are also destabilizing planes. Increase in Kiel (preferably tall) will solve the problem.
by the way lack of stability can be checked without alteration, attach the tape as on bojcovkah.
If the lack of directional stability manifests as a pendulum with lateral sliding. When this offset CD on the transverse axis leads to roll.
Andrew, can't even zoom in Kiel, you can glue the aerodynamic ridges at the bottom of the stabilizer. They can be made of transparent plastic, bottles).
Still, I almost forgot, this is not a "classic" high-wing and longitudinal triplane.
when calculating the PGO bottom, simply put-centering will be configured over the front.

1/are the normal exhibitors? I have a èleronah 90х60.
2/kabančinki on the èleronah stand at the very edge at the other end of the aileron great burdock. Starts at high speed dejstvat′ bending moment, when stick èkleronov-bend in the other direction and begins to swing. In short there is hardness transfer efforts on the entire surface of the aileron.
Need pylons to rearrange around otrienitruâs′ centered on the square. Or strengthen the rear edge of the aileron. Or move the stick smoothly and gently.
I'm on their penoletah don't vykosa-and so everything is normal. Zal′nikah on do-in order-to power keg hanging evenly without rotating.
It would still be on the ground, drive better on asphalt show straight rides. And where lurch.
Here are-so pure imperičeski ...
good luck!
complete the repair, while in no time. You for building fat plûsiŝe!
are you going to build a DB-a! ... If Yes, then keep your eyes peeled! What scale? This is the same huge 4-x motor airplane!. Success in the works!
scale approx. 1/24. Now span (3D drawing) 1695mm, length 1000 mm
model is built around "these engines:
here is that as long as goes:
with start doing according to drawings with INET, now over on new photos
