The Translation May Not be EXACT ! . 

In a certain topic, I talked about special explosives for aerobatics. I could not find the topic, I'll post it here. The dimensional accuracy can be calibrated when printing on the base marks. Success!

Dont Ask Me . Im just the messanger .  . Rockers seem to be common to cord in those parts .

According to eyewitnesses, the aircraft against the backdrop of farting Talochek looked very innovative and provocative.

[Steve Helmick]

The airfoil looks really thin and far too sharp LE to suit Ted. But what do you think the odds are that the F1 driver Sirotkin is related to our Sirotkin?  Steve

Calling It " Moscow 22 ' here

Hello Matt
                      Do you know if there are plans available for that jet styled stunter?
                                                                                                                                        juan

Hello Gordon
                           Thanks but  I`m interested in the Jet Sirotkin designed. I find it real nice and interesting,using the jet pods as wheel pants was a stroke of genius. I have seen a similar design by Mike Stott called the Fantom but I like this jet stunter better.

I read an article on the jet style plane and it said that there were 2 wheels in one pod and one in the other.
(Trike u/c I guess)
Not sure if the 2 wheels were in the inboard or outboard pod. My guess is inboard.

Juan,
I believe it was published in Aeromodeler Magazine sometime in the Mid to late 1960's.  I remember seeing it when I was stationed in Malta.  However it may have just been an article about it with pictures  actually saw the airplane once in Germany (maybe 1967) not sure about dates anymore.
He didn't actually fly it there and the general consensus was that it didn't work very well...Too Heavy!
I saw a couple of his earlier airplanes fly and they were spectacular!
Back in those days it wasn't possible to talk to the Russian fliers very much because they traveled with an Army of Secret Service Guys!

Why I put the Drg in #4 on , its a proper draftsmans drg. rather than artists .
However its the WRONG PLANE . However seems its the same ' series ' ,
so Drg ' adaptable ' perhaps .

Tho as said elsewhere . THE WING NEEDS TO BE THICKER .

As Randy says , there was a wee sketch , in the aeromuddler . back then . ( same year as comp ? )
However our Russian allies may be able to access The Original commie Sketch / drg. it was no doubt purloined from .
A word or warning tho , some dimesioned drgs. are no more than ' Artists Impressions ' and bear little accuracy .

Blowing Up Photocopies , establishing Vanishing Points - Parrallel Lines ( To V.P. ) could enable you to establish a GRID
( with diminising squares both ways ) To get a pretty good approximation . Study the plan in post #4 , go from there .
Assume same rib space & span . For Starters .

Should be possable to access that forum , to ask for Drgs . Eugene Here is a member there .

Check Your PMs Yuan .

That "Moscow 22" is what we know as the Spacehound.  Photo taken in 1964 when Sirotkin won the Worlds.

[Bob Hunt]

Here's a photo of Bob Gialdini and Juri Sirotkin. Not sure where it was taken. That's obviously the model in question that Mr. Sirotkin is holding...

[Lauri Malila]

Found these..

[Scott Richlen]

Doesn't RSM kit the Spacehound?

But that twin-engine jet would be really cool.  We just gots to find the plans!!

[Air Ministry .]

Transfering pictures over from Classic ,





Slightly differant angle .
Wondering if moments / fuse. are basically the same , hasnt alowed for sweep / c g shift . As in Nose Heavy excessively .
Of course if EEE lectrick , that wouldnt appy .

    Hello Matt
                            I sent a message to Yuriy Yatsenko asking for information about the Juri Sirotkin Jet. he kindly replied:

  Dear Juan.
I would like to help you but I have found just photos of this model but not any plan.
I think it was not published never.

Best wishes.
                                                                                           Yuriy Iatsenko

                                                                                                                                                                                               Juan

Is there any bio written on Sirotkin?  Considering his abilities you'd think there would be a lot "out there".

[Steve Helmick]

I tried a search for Juri Sirotkin and didn't find a Wikipedia-type bio. I did find articles or plans for the Space Hound and that ugly elliptical successor, but not the twin jet Merco .49 model. Darn it!

Note that the guy on the right in the first picture is Juhani Kari. I believe I read that Kari has left us, but expect Lauri would know for sure. What I recall was that the Finns were trying to rescue and maybe restore any surviving models. Who doesn't love the "Nakke", and young Juhani's 2nd placing in the '64 WC? But also note that Sirotkin used a low pitch propeller, high rpm run, and we didn't pay much attention.    Steve
 

[Istvan Travnik]

Wow!
The very first photo was made at Budaörs (near Budapest, Hungary) at the 1964 WChs.
This place was our "second home": I flown over there from 1969 to 1990. Then we, modellers were simply kicked off...

Now there is no reason to "revitalize" this circle, since the maximum possible radius up to the street fence is no more than 24.5 meters.

[Scott Richlen]

So, nothing ever turned up on the Sirotkin jet?

[Air Ministry .]

No. Bugger .



Search of appropriate year AEROMODELLOR Mag , England . could be fruitful .

The fuselage is made of balsa. Side panels in the bow - 5 mm thick, in the tail part - 4 mm. The upper and lower halves of the fuselage are dug-out and in the section they have the shape of a semicircle. Motorama - combined design: its power part is made of hornbeam, and tail is made of linden. This design allows you to gain some gain in weight. The nose of the model is quite long - 270 mm. The model has an Acrobat engine (7,0 cm3) designed by the master of sports of the USSR Yevgeny Petrov.

Hood - small, 6-detachable provides access to the engine and to the fuel filler pipe. In the forward part of the fuselage, there is an air channel that goes to the bottom of the fuselage. It has a boss for fixing the nose of the chassis.

In the middle part of the side panels there are openings for the edges of the wing, the flanges of the spar and spikes of the central rocking unit. There are only 2 frames along the entire length of the fuselage, since the fuselage is made of a carrier and a large number of frames is not necessary. The front lug is made of duralumin (D16T) in the form of a thin ring. To the motor torch and to the side panels, the front boss is glued with epoxy resin. Assembly of the whole model is done with the use of cement. (Cement can be prepared by yourself, to do this, it is necessary to dissolve the celluloid in acetone and add a few drops of castor oil to make the glue plastic.)

The wing is assembled directly on the fuselage. The leading edge - whole dolblenaya, bent. The pre-treated edge is steamed in hot water and in this state is bent exactly along the contour of the wing on the slipway. After the balsa is completely dry, the edge is finished. The rear edge is also integral, dug-out. Shelves of the spar are made of small-sectioned pine with variable cross-section; in the central part - 7X4, and at the end - 5x2 mm. Such manufacturing of the side members of the spar is necessary to obtain an even-strength structure. Over the entire span of the wing there are 32 balsa ribs 3 mm thick. The wing is entirely lined with balsa veneer (thickness 3 mm).

In the outer half of the wing is a cargo - 35 g and a wheel with a diameter of 35 mm. The flaps are made of balsa and, due to their small dimensions, have quite sufficient stiffness. Both the flaps and the elevator are suspended on metal split hinges, which is a great convenience when finishing the model. The relative thickness of the wing profile is -14%.

The model uses differential control. With the maximum deviation, the inner flap deviates more than the outer flap by 2 °. This is quite enough for the model to create the necessary tension under the most unfavorable flight conditions. The big difference in the flap deflection is extremely undesirable, since when moving from direct figures to reverse (and vice versa) the model will noticeably sink from wing to wing.

Stabilizer is whole balsa, with a relative profile thickness of 7%. The area of ​​the rudders is 45% of the area of ​​the stabilizer. The handlebars are deflected by 40 °, the flaps by 3 °. The keel is made of balsa plate and is embedded in the upper part of the fuselage. To increase the tension, the rudder is turned to the outside by 10 °

The chassis system is a bicycle type with one bow and one main wheel. Racks of the chassis are made of sheet titanium. The total weight of the racks and wheels is 45 g. The central stand is located 20 mm behind the CG.

The model's tank is made of metal, made of duralumin foil 0.2 mm, glued with epoxy resin, the seams are glued with fiberglass. Its capacity is 120 cm3. Refilling of the tank takes place through the feed tube. The non-removable tank weighs only 15 g (a tin can weigh 70 g).

For the manufacture of the model, it is desirable to use a balsa with a specific gravity of 0.07-0.1 g / cm3.

The surface of the model (especially if the wing is covered with balsa) should be very carefully prepared. First of all, it is necessary to close the pores of balsa. For this purpose, chalk filler or epoxy resin is used. After a careful treatment with sandpaper one time spread with epoxy resin. The resin not only closes the pores of balsa, it still makes the whole structure more rigid. In this case, various deformations are completely eliminated over time.

Then, pile is removed from the surface with fine emery paper. And the whole model is covered with an enamel of medium density three times. Once the enamel is completely dry, the entire surface is covered with a nitro filler. To completely dry putty, you need 1.5-2 weeks. Only after this you can finish the model.

Coloring can be the most diverse, depending on the artistic taste of the modeler. In the process of painting it is necessary to constantly remember that the appearance for the aerobatic model is one of the most important factors. A good finish can almost eliminate all the errors in the manufacture of the frame. Before starting the finish, it is desirable to perform several coloring options for the model. This is convenient to do on sketches in a scale of 1: 10, in order to be able to choose. During painting, it is necessary to remember that stronger tones are superimposed on weaker ones, Otherwise, paint will need much more.

WEIGHT DATA OF THE ELEMENTS OF THE MODEL (in grams)

Motor frame, frames and engine mounts - 55, fuselage sides - 45, front edge - 15, trailing edge - 30, flaps - 20, spar - 30, ribs (32 pcs.) - 28, metal hinges - 8, -120, cargo in the outer wing - 35, upper and lower parts of the fuselage -45, hood - 7, landing gear and wheels - 45, control - 70, stabilizer - 35, keel - 15, cab (plexiglass) - 14, cab equipment - 10, the motor, the screw, the cook - 230, the tank - 15, the primer and the paint 200, the glue for the assembly - 20.
