USSR AFV-10 Glider in 1:4 scale

[Walter L.]

Hi Nikolay,

I just looked at Google Maps were you live. It is quite near to Japan....

From the distant view it seems, that not very much people live on your island. Are there other people building airplanes in your neighborhood?

Your construction is of very good quality and with all of these metal parts it is very complex!

I am wondering from where you get all the special materials at "the end of world" (sorry if I have a wrong impression....).

Please report soon about all progresses.

Kind regards
Walter

Hi, Walter,

Yes, indeed the Sakhalin Island is quite far away from the developed areas and Moscow or whatever. However the Island is quite developed and it is enormous business with oil and gas exploration (western and Russian oil and gas companies). A great deal of people lives on the island, for sure, not like in Europe, but it is normal density of population for Russia, as Russia is huge.

I have some time difficulties to buy some materials for hobby, but it is general problem all around the Russia as to buy the cheap hobby materials and electronic parts. All specific materials (balsa, electronic parts and etc) come from abroad. So, it is matter of planning when you do some hobby.

In general, it is delusion about the Far East of Russia, but some cities in this region are quite developed and have the folks who have interest in hobby-modeling.

As to retro-glider modeling I would say, it is not so much folks in Russian hobby society who takes interest in this. But the airplane building hobby is quite developed.

Walter, Ich kann deutsche Sprache verstein und ein wenig schreiben. Die deutsche Sprache ist meine zweite fremde Sprache studierte ich einmal. Wir haben Ski und Snowboarding und weiter.

Vielen Grussen,

Nikolay

Wahnsinn-wie weit unsere Retroplanegemeinde geht.

Ich bin richtig stolz auf unser Forum und dass unser schönes Hobby auf der ganzen Welt so eifrig betrieben wird und wie klein doch die Welt dank Internet geworden ist.
Da kommt doch gleich ein wenig Weihnachtsstimmung auf

Dear Nikolay

As Walter, I was very impressed by the quantity of snow in your region and as Walter I was also looking at Google Earth.
Sakhalin Island? Never heard about these Islands. It is now very cold? I notice very cold in the winter and acceptable temperature in the summer.
And a lot of history. Not always simple during the centuries.
From our side of Europe, we have the impression that you are living on the other side of the world. So far away.
You have good slopes in your region?
Maybe Vincent may organise a future Retroplane in Sakhalin Island?
Good construction and best regards.
Harold

When we built Sakhalin-2 project (Shell) there were so many people from Europe here and still there that they do not want to go back to Europe as they see that Russia and Far East is Indeed marvelous place to be .
We have slopes downhere but I am still in search of finding the good slopes as the most slopes are wild and out of roads, only for off-road cars.

Hi, Gents,

Long time I did not post a progress done for AVF-10 glider model. So, having spent a lot of time I managed to build what I present now.

You may see that I did put all servo under the chair of pilot, and all controls are done like on real glider. That was my idea to adhere to original controls of ailerons and rudders.

I weighted the model and the model weight now is 3 000 gr, the design weight should not exceed 4 200 gr. The wing load should be around 40 gr/sq ds.

There are some things to do like to apply wire-bracing with turnbuckles (80 pc). But the major job is done.

Note: Wire-bracing is not fully installed i used for the time being a rope for trail fitting. Later i will use metal wire-bracings.

See the short move how the remote control works.

Hi Nikolay
Congratulation, beautiful all these détails, pulleys.. great the video, funny the cables in exterior for ailerons

[Anonyme]

Great building Nikolay . I think you will have to verify the electric consumption with all the servos with the movment of all these cables and pulleys. The servos are noisy but I suppose they are digital and that the room makes the sound louder...

Hi Nicolay,

Gorgeous work, happy to follow your building.

I love russian planes as you can see...

Waiting for next pictures,

Yours,

Jean-Paul "Papy Solex"

Gents,

The cables are exterior fitted in the same way as for original model. However there are slight changes I put the upper cable inside the wing structure as to remove the friction of air above the wing. The original one has the upper cable on the exterior surface of wing.

Why so noise, it is explainable, the glider is on garage, there is echo and the cables and wire-bracings are just temporary mounted without proper tensions.

I need to make some improvements still. But the controls work and movable parts are moving as it should be.

[Walter L.]

Very nice!

You made great efforts with details of fittings and other small parts.

Best regards
Walter

A status with construction as of 30.03.2014.

So, almost all major work is done. There are a few things to be yet done.

I started a coat of varnish of some glider parts.

I am in doubts about vanishing the wings parts inside, is it needed to be done or not prior to apply covering?

Nose part is detachable for easy repair in case of crash. The pilot seat is also detachable as to get easy access to servos.

I have faced a problem to buy Diacov 100 - termofilm, there are a few internet sites where Diacov 1000 can be purchased in France, but all of them are in French and they do not have options to deliver the goods in Russia, too me it is strange. What is the problem to sell the product to Russia?

So, who might give advice or help how to buy Diacov 100 from France to Russia. I need around 15 meters with width 0.75 meters of Diacov 1000.

Hi Nikolay, beautiful work
for the fabric, where did you ask to buy it? Weymuller? if they don't want to sold it to Russia I can order it and shipp it to you. Continue in private

[Anonyme]

Great work Nikolay. I think it is not useful to varnish wings inside prior covering...

[Nikolay Lebedev]

Hi, Gents,

i have almost completed the glider.

see the thread and a small movey.

Great Job, nice wood work ,Nikolay

[VincentB]

Hi Nikolay, congratulation, beautiful work, all these détails are for me the most pleasant, especially the spoked wheels. I don't see on the photos, how you made the rims? like me, in steel? or in brass?

[Nikolay Lebedev]

Vincent,

I wanted to place the photos, but I struggled with the requirements to reduce photos to 100 kb and 600x600. Why not to make it automatically in your site:-).

Nikolay

[VincentB]

I could have the system with GD library but the original big file will be hosted on the server and take space disk, so I prefere that everyone resize himself his photos, it's easy and quickly

[Nikolay Lebedev]

Vincent,

Some photos attached below. The wheels I did by the same method as you did, but I did not use hard-soldering because hard-solder temperature soften the spokes. But if we use a soft-soldering the original strength of the spokes remain the same as no effect of high temperature.

Actually to design and construct this model for me was a big challenge but the major job is done and I have to cover the model only.

I will post the pictures of covering process later, say end of July as now I am going to vacation, have some rest.

Hi Nicolay,
It's really wonderful !

[Clifton]

Very nice build. Original Sailplane.

Hi Nikolay,

it is a really impressing glider! So many details like fittings, wires and the wheels.

I am waiting for the - of course positive - informations about the first flight.

Best regards
Walter

[Nikolay Lebedev]

Gents,

So, I completed the glider. Everything is done. The flying weight is around 4800 gr. Charged wing area 46 gr/sq dc. Wing span 3 meters.

Some weight left for balance, but it is almost 30% of the cord (365 mm).

Soon I will try to launch the glider by bungee start. I am afraid to launch it, I spent around one year to build it, so if it crashes, it will be a sad day for me.

In any case I will try to launch it.

P.S. It is my first experience to use Diacov tissue, it is very good and light for application tissue with good adhesion and shrinkage properties.

[VincentB]

Congratulation Niikolay, the covering is clean
would you aging the Diacov with wood tint?

[Nikolay Lebedev]

[GARCIA]

Hello Nikolay. Congratulations for this beautiful construction.
Your Avf-10 flew?

[Greg]

Yes, really nice work, and y wish you many nice flyghts

[bocorvin]

You are doing a great job!
I surely like the detailing.
