Hi Misos,
very nice plane. Only, rather boring for its painting, apart for some prototype.

Good work, Misos.
Please, check the shadow on the rear of the nacelle: if the outlet flap has a corner in light, it has to project shadow somewhere.
Besides I would darken a bit in front of the inlet, because it intercepts part of the diffused light from the rear.

Hi Massimo,
thank for comment. I added  a bit darker area/shadow in front of nacelle. Almost whole rear part of the gondola is in the shadow. So a little shadow from the open outlet flap is whithin a big shadow from the wing. At least in my interpretation.
Plus I added a little shadow beneath exhaust pipe. I replaced the corrected picture in my previous post.

Hi Misos,
imho, if a thing is lightened by the sun, it has to project its shadow somewhere. If the flap is within the shadow of the wing, it can't have direct sunlight.

Hi Massimo,
I have to admit that you are right. So outlet flap is closed now, picture is corrected and replaced. Wink
Thanx again.

This is Yak-2:


And this is Yak-4:

Hi Misos,
a strange characteristic of these planes: I can't understand how the hood of the pilot opens. I think that it has to be  removed by the ground crew.

Hi Misos,
good profile as usual.
The photos show some bomb racks under the wings.

Hi Massimo,
Thank you for comment. I do not have picture or drawing that shows exact shapes, dimensions and position of the bomb rack on Yak-4. And that rack was apparently removable. All line drawings I have found are without it. So let's say that my profile shows that plane before the rack was added.

Hi Misos,
the profile is nice but IMHO, fundamentally wrongLips Sealed

the profile you made, conveys an idea that there was a 3-colour, green-dark green-black, camouflage scheme. Such a scheme definitively did not exist!
Yak-2 your profile represents was painted strictly in accordance with the June 1941 scheme in 2-colour black-green scheme:



Plane probably belonged to 514 rap, photos were made in summer 1941





I don't know why black fuselage bands look lighter on some photos - photographic material, lighting conditions, fuselage  could be dusty and nose could be wet...

Hi KL,
basicaly I agree with you - official scheme was black & green.
Here are another photos of the same plane I have found on web:







I havea to admit that camo on the plane (front & middle sides of the fuselage, wings, engine gondoles and vertical stabilizers) quite well fit to official camouflage template. However, the black is missing around the horizontal stabilizer root. Fabric on the rear left side of the fuselage is missing, we can only guess whether black was also there or not.

My original interpretation was that originally dark green (AIIz?) plane was for some repainted in the filed conditions to the new scheme, but black either poorly covered or it was mixed with new AMT-4 green to get enough paint or something like that. Those photos are usually dated to summer/july 1941 - time when Soviets at the fronts had completly diffrent problems from looking for perfect black.
Where is that color scheme from, please? The fuselage star is missing there - same like on that Yak-4. AFAIK there should be two red stars - on the rear fuselage side and on the tail.
However, if we suppose that plane was camouflaged already in the factory/PARB and different dark shades are only matter of light conditions and/or optical illusion then, of course, there should be only two colors - green (AMT-4) and black.

EDIT:
Here is reworked version to fit official NKAP template:

Hi Misos,
that was a quick correction!!!  Smiley

Drawing is from original 18th Army documents, thanks to Misha Timin.

Photos were definitively made in summer 1941, plane belonged to 314 rap, it was camouflaged in field (not in factory).

Camouflage orders were issued on June 20, AFAIK location of stars was regulated few days/weeks later...

Hi Misos,
I think that the painting of the blades has to be revised, As it is now, it seems metal partially oversprayed with black. The photos show it somewhat different, at least on the rear that had its outer 3/4 painted black in factory. the upper blade of the profile should show its back.
