Mikoyan, Gurevich, Yakovlev and Tichonravov were the Soviet pioneers in this area.

Models of early soviet jets in 1/72 scale covered:

1. Bereznjak Isajev BI-1
2. Tikhonravov I-302P 
3. Mikoyan Gurevich Mig-9
4. Mikoyan Gurevich I-270   [on page 2]
5. Yakovlev Jak-17  [on page 2]
6. Yakovlev Jak-23 [on page 2]

The Eastern Express kit (no. 72203 ) in 1/72 scale has about 40 short run injection plastic parts and it is a very small model. The kit was I believed originally issued by VES model , Voronez from Biela, Russia and the Pioneer kit is probably the same mold. Accuracy seems to be quite good, a plane is in the Monino museum.
The surface detail is very fine with nice engraving with lots of small detail but it is short-run plastic. Cleaning up and filling tiny gaps with putty is required and a very fine hands as the model measures only 9 x 10 cm. It's box is very large, at least 8 kits could be in it! The decals are not very good. Instructions are nice with history details in English also of this aircraft. 

The tiny canopy is clear but one piece. The kit gets you  a neat model and some extra options can be made for which parts are supplied. You get also a set of skis.
I selected the version with the tip mounted engines. 

Interior colours are probably ghost grey with a green seat cushions. 
===================
The "ramjet' pods were fitted to the wing tips; these were fitted on the sixth BI-1 according to the instructions.

Gear attached and the "end plates" to the stabilizer. The cockpit is very small but some nice details are provided in the kit. Cockpit was added with some white glue to fill the small gaps.

A very nice special model to the collection.
 

The Amodel (kit no 7220) in 1/72 scale has about 15 parts and is short-run. It represents the flown test glider. It is a limited edition short run kit and needs some parts cleaning up. 
For the single plane, the red-stars are provided as decals.

You will need some obvious filling and putty in areas.  The wing-fuselage joint needs considerable filling with putty but otherwise the kit was made straight out of the box. There is hardly any detail in the cockpit but it is very small. The painting of the canopy frames is challenging, use painted decal cut in strips here. Also, the gunports were drilled out.

Lower view with legs attached. I drilled two holes to receive the gear legs.

Some details from card and strip were added to the small cockpit.

Colours applied were upper green of Humbrol 105 and the lower surfaces Humbrol 65 light blue.
The cockpit did not fit very well, some white glue was used to close gaps. Two metal pins from a paperclip ("gun simulation? ) were added to the nose.
A wire antenna completed the model.

Modifications to initial Mig-9: 
I-301T/«FT» - The I-301/I-301T - Mig-9L: was a two-seat trainer development of the MiG-9. Two built. 
I-305 - Version of the MiG-9 with two Lyulka TR-1 engines. One built. 
MiG-9F/I-307 - A development of MiG-9 with two RD-21 engines. 
MiG-9FR/I-308 - The recco modification of MiG-9. Two RD-21 engines. 

The Mig-9 was replaced by the much better MiG-15.

Amodel (kit no 7206) in 1/72 scale has issued a model of this little jet and it is short run which requires some cleaning up of the plastic parts. 
[ NOTE: later on , Amodel issued an updated MiG-9 kit, no. 7299 ]

About 40 parts and a small decalsheet for a 1950 and 1958 Mig-9 are included and a Chinese Mig-9 are included. The basic plane is light grey. 
Wingspan and length accuracy of the model is quite good and it looks like a Mig-9.

The trailing edges of the flying surfaces of wing and stabilizers needs thinning them. I merely sanded the areas here and this results in a much better appearance

                     a large gap is on the lower end of the tail

There is some detail in the basic cockpit with a tub and seat. It is very small and not much can be seen later on. Panels are engraved but a bit rough. With some work a nice little model can be made. Putty is required at the joints and especially at the wing roots. I strengthened the wing-fuselage joint with some small metal pins with holes drilled in the appropriate locations.
I also replaced the pitottubes and gunbarrel.

The Mig-9 got as all other models a grey base coat. It was discovered that there is some plastic shrinkage ("irregularities") op the upper wings and the fuselage spine needs some extra sanding.

Final colour used was  an overall grey coat of light grey using Humbrol 128. It was decided to put a cover on the intake to added some colour and to mask the very rough model intake. 

It was found later that the cockpit glass had a step at the windshield. A small thin piece of card to have a smoother step. 

Only the red stars and the number were used of the decals. Cutt out the stars with scissors to remove decal film. Fine stencilling was simulated with some red paint applied with a tooth pick.

Unfortunately to prevent tail sitting, a very thin metal wire was required below the exhaust area.
A wire antenne and gun nozzles were added as well as a pitot tube on the right wing leading edge.
