AMK will release a MiG-31!


Recommended Posts

Fabulous looking model, it will certainly grace my shelves, and for that level of detail I am not going to moan at 100 dollars - look how much aftermarket details make 'normal' kits cost.

Two questions though, firstly will the instructions define how much weight (if any) will be required, or dare we hope include a shaped weight?

Not sure if it is a tail sitter yet. If so, we will make it clear.

Secondly, I note that either side of the cockpit is a small fairing that goes to the engine splitter plates, and these have what look like deep sink marks on the upper surface - are these moulding marks or are they representative of some feature that is there on the real aircraft?

Cheers, guys, looking forward to seeing this

Good eyes! It is sink mark. Those are just testing samples, and it won't appear in the final plastics. :D/> :D/>

Thanks, Sio, I hope you didn't think it was a criticism!

It must be difficult to prevent in certain areas, and is something we are all used to dealing with. I suppose a pair of related questions concern moulding / cooling flaws in the transparent parts (didn't Airfix recently have an issue with this?) and the dreaded ejector pin marks. Have the transparencies been test moulded yet, and are there any details of how the ejector pin marks are being mitigated?

I'm pretty confident seeing the rest of the attention to detail that they won't be an issue, but it would be great to hear about the thinking behind any design details on this

Thanks again!

No. It is not a criticism.

To minimise the ejector pins marks is hard to explain, or can say a combination of design and mould technology. :D :D

Layout of the ejector pins is a systematic thing or more an art of the engineer thing (based on expérience and educated guess) ?

Sio, I have just been back and forth through all the photos, and the more I look the more I am impressed with the technical side of this kit. I can't claim to know the MiG-31 in any detail so will leave the accuracy comments to the guys who do. But further to my comment about ejector pin marks, what few I can see are either in irrelevant areas or really subdued, the latter being in the engine intake trunking / landing gear bay areas - are those as-moulded or have they been lightly dressed? I hope the landing gears doors look as good as that!

Another question I have concerns the full engine assembly - do you have to make all that detail and then have to hide it away in the inside so that they support the compressor inlet and turbine rear faces / afterburner augmenter tube? It seems such a shame, they look like the basis for a kit in themselves, and beautifully rendered.

Very impressed, you should look at a MiG-25 next.....please! Or maybe an SR-71.......

Ohoh! Guys,

You want me to make a lesson here for kit design and production?

That is lots of work for me! :D :D

Since I haven't seen any mention of the 'plain' MiG-31 variant being announced by AMK, are there any external differences between a MiG-31 01DZ (standard MiG-31 fitted with a refueling probe - not sure when these were first introduced?) and a MiG-31B? I presume those would be minor if any, so I hope Begemot offers some MiG-31 01DZ decals.

First will be MiG-31BM\BSM decal:

Yes, as say Berkut - it will be aftermarket decals from Begemot.

Which decal will be in box of AMK model - i'm don't know, but at my look so comprehensive decal - its too much for producer, cost of this decal will be to expencive, its will increase cost of model.

i'm looking forward for this new Begemot decal set as wellsmile.gif...and, as i plan to buy more than one of those upcoming AMK1/48 mig-31, i'm pretty sure i'll wish to use Begemot decals on one of them, at least!

Test shot being built here: http://ipmsnymburk.com/forum/viewtema.php?ID_tema=38975&page_d=0&idp_d=0&idc_d=1&show_html=

Google translating the captions...

http://ipmsnymburk.com/forum/pictforclanek/1443721657.JPG Parts fit very well thanks to rectangular alignment pins, which fit into a slot in their counterpart. Assemblies are already dry and a little Tamiya Extra Thin was enough to fill the seams.

http://ipmsnymburk.com/forum/pictforclanek/1443721701.JPG Because I am building without instructions, I made a dumb mistake. The part has to be turned so the cone points backwards. Fortunately I realized this and was able to remove the part and reattach it properly.

http://ipmsnymburk.com/forum/pictforclanek/1443721728.JPG This part is molded separately. It fits perfectly.

http://ipmsnymburk.com/forum/pictforclanek/1443721748.JPG Cockpit tub is insterted into the one-piece nose section from the rear.

http://ipmsnymburk.com/forum/pictforclanek/1443721773.JPG Wheel hubs are separate = a good thing for painting hubs and tires. Hubs fit perfectly into the tires. You have to clean up all traces of of the attachment point on the joint. (tree stumps but it must be machined = remove feeder heads on the center joint.). Personally, I would prefer to see whole tires because the joint will need some sanding and filler.

http://ipmsnymburk.com/forum/pictforclanek/1443721793.JPG Nose cone fit is excellent, alignment is done with a tab which is inserted into a groove in the forward fuselage.

http://ipmsnymburk.com/forum/pictforclanek/1443721858.JPG Here you can see how the wing joins the fuselage. I have intentionally spread the assembly apart in order to see how it is broken down.

http://ipmsnymburk.com/forum/pictforclanek/1443721878.JPG View the inside of the fuselage from the rear before gluing the upper parts of the engine.

http://ipmsnymburk.com/forum/pictforclanek/1443721901.JPG And again - nose locating pins fit into the rectangular hole.

http://ipmsnymburk.com/forum/pictforclanek/1443721927.JPG ... and underneath the rails on the sides of the nose landing gear well. It fits ... However, again as you know what :-)

http://ipmsnymburk.com/forum/pictforclanek/1443721946.JPG Air intakes are made from 4 pieces. Here they are fitted to the fuselage without the use of glue.

http://ipmsnymburk.com/forum/pictforclanek/1443721996.JPG Join between upper fuselage and wing to lower 'box' is here.

http://ipmsnymburk.com/forum/pictforclanek/1443722030.JPG This part is affixed to the hole and fits very well.

http://ipmsnymburk.com/forum/pictforclanek/1443722065.JPG Exhausts attached without the use of glue. Perfect fit? Perfect fit!

http://ipmsnymburk.com/forum/pictforclanek/1443878997.JPG I had to push here to get the contact surfaces to touch each other. Attachment of the "fin" to the fuselage is again without the slightest gap.

http://ipmsnymburk.com/forum/pictforclanek/1443879052.JPG The tops of the "fins" are interesting. They have different engraved details; the left has rivets but the right does not.
