Scale Bureau 1/48 Yak-9U (P) By Aleksandar Sekularac

Introduction

Zenith of Yakovlev’s “9” family of aircraft – the most numerous and influential lineage in the VVS from 1943 to the end of the war – was achieved with Yak-9U and its all-metal progeny, the Yak-9P. These were the last production fighters with internal combustion engines to come out of the OKB Yakovlev.

The marriage of the aerodynamically improved “9” airframe with the mighty but temperamental Klimov VK-107A 4-valve supercharged V-12 secured unrivaled performance, yet brought along number of complications as well. New powerhouse had notoriety for overheating and loss of oil-pressure, with very poor operational life expectancy. Continuous improvements to the engine and the cooling system, particularly replacing the radiators with more efficient units (OP-728 and OP-726), alleviated some of the issues (by the beginning of 1945), but the engine remained the “mechanic’s-nightmare” throughout the production.

Yak-9U was christened in combat in October 1944, establishing supremacy under all conditions over its common Luftwaffe opponents: Bf-109Gs and FW-190s. 32 machines were delivered for the first time to the 163 IAP for combat trials. In the short period that followed 28 enemy fighters were destroyed in aerial combat for the loss of two Yaks. Broader introduction to service was equally impressive. With the implemented production improvements Yak-9U became more reliable and its performance further enhanced.

In the closing months of the war came the proposal for the heavily armed fighter, the Yak-9UT. Great array of weaponry was tried, firing through the propeller shaft: the ShVAK, B-20, Vya-23, NS-37, and even the super-heavy 57mm anti-armor cannon (ultimately rejected). This version however did not see great numbers, with less than 300 produced.

The post-war, all-metal Yak-9P became a common sight on airports in occupied Germany. “P” also went to serve with many allies of the SSSR after the war, subjected to numerous modifications. It was also thrown in combat in Korea, but soon becoming an underdog to the galloping jet propulsion.

The Kit

The old saying: “what looks well - flies well”, holds true here, and it is only proper that these ultimate Yaks are also the sleekest of them all.

To my knowledge there were no kits of this aircraft type in 1/48 scale until now. So, Scale Bureau from Moscow gets a big bonus right from the start, by tackling this significant and attractive subject, ignored by the mainstream producers. Sometimes this would be enough to recommend the kit as the “only game in town”, but Scale Bureau luckily does not play on the novelty card alone. Not by a long way…

This is an all-resin kit – the qualification sufficient to turn away 80% of otherwise enthusiastic modeler a decade ago. But not today! The comparison of this kit with recent state-of-the-art products from Vector, mainly the 1/48 Lavockin family, is almost inevitable. Indeed, the two are very similar in approach and achievement. Similar, but not the same…

The kit is skillfully cast in mellow-olive resin. Parts are very light, so the finished kit will weigh no more than its injection-cast styrene equivalent would. Truly commendable, this! The surface finish is very good, with almost no imperfections at all, and only selected places needing light sanding to bring them to smoothness. Details are excellent throughout

All main flying surfaces have line-contact casting gates, much like the early Vector kits. Curiously, fuselage halves are free of any casting blocks/gates, and only some thin resin film needs to be cleaned before the assembly.

There is an abundance of well cast details in the cockpit. Instrument panel is made solid, with instrument backs and blank fronts, while instrument faces are supplied all as individual decals. A novel approach in this scale, but the poor resolution of instrument decals renders them little more than black dots (see image at the bottom). I’d personally prefer the perforated resin panel and acetate insert with printed instrument faces.

Some work is needed with the tubular side structure elements in the cockpit. These are cast on a wall of resin, and instructions call for this wall to be removed in-between the tubes, using a scalpel. Instead of the brute force approach that can result in some damage to the resin and/or fingers, I’d advise to simply sand the underside of this block of resin (against a flat surface) until the resin wall becomes see-through thin, at which point it can be removed even with a toothpick.

Excellent work in the cockpit is reflected on all major outer parts as well. The control surfaces are all separate (flap inner structure is sublime), trailing edges straight and sharp, panel lines well defined, exhaust stubs superbly sculpted and hollow, tricky wing-root intakes very clever and elegant (superior solution to Vector’s LaGGs here), landing gear elements precise and proper… in short, it will be a pleasure to build this kit.

But, what type is this model exactly representing? To answer this question I had to do a bit of research and school myself on nuances of Yakovlev’s late-war design evolution. As usual with all things VVS, one finds all sorts of vague, ambiguous and contradictory claims, but after a while it is possible to distil some sense out of it.

The biggest point of contention was the shape of wingtips. Beginning with Yak-9M and ending with Yak-9P there were three distinct wingtip shapes (see attached image) and the kit definitely represents the final one. The standard Yak-9U wingtip (the middle of the three) is very hard do discern on photographs and can be easily confused with the rounder -9P wingtip, particularly from a shallow angle (due to the similar arrangement of the nav-light bulbs). Never the less, the two were different!

Scale Bureau kit therefore offers the Yak-9P wing, but without visible panel lines associated with the all-metal Yak-9P construction. Stern fuselage halves are also smooth, as on the wooden Yak-9U.

So here’s my finding:

• This kit is closest to the very early series Yak-9P – built with the wooden fuselage (as on Yak-9U) and the metal wing. Still, there are no panel lines on the wing in the kit.

• The kit can be easily converted into the standard Yak-9P, by scribing appropriate panels on the rear fuselage and the wing, rearranging small scoops on the engine cowling (provided as separate small parts in the kit) and - if required - cutting out a window for the Plexiglas cover behind the cockpit and using some acetate to replicate it (not present on all Yak-9Ps however). This said, I wouldn’t object much to a modeler who forgoes the paneling work altogether for the -9P variant, as all the additional panels are practically invisible on available photographs, in contrast to the patently rough and very visible engine cowling panels on these Yaks.

• To build proper Yak-9U however one would have to modify the wing-tips (not necessarily a trivial task). To make this kit complete, and support the claims that this is indeed the Yak-9U, Scale Bureau would need to include alternative wing tips for the -9U version While they’re at it, why not make the bullet-like gun camera as well? This accessory is seen on many Yak-9U/Ps in front of the windscreen (not mandatory, but a very handy piece it would be).

OK then, with this topic absorbed, all other kit elements look accurate against available references. Without a doubt this is the most authentic representative of Yak’s “9” pedigree in 1/48 scale (ICM kits have many geometric problems in comparison).

As previously mentioned, the decals are provided for Yak-9U and -9P types, on two extensive sheets made by Begeomot (one for each). The camouflage instructions are given only for the Yak-9U however. To anybody interested in available -9P variants, I’d recommend getting Mushroom Model Publications “Yak-9U & P” book, where large scale color profiles exist for all the aircraft from these two sheets.

The available choice is as follows:

1. Yak-9U SSSR, “Vahtangovets”, 29th GvIAP, winter ‘44-’45 - Karelia
2. Yak-9U SSSR, 6th GvIAP, 1944 – Black Sea Fleet
3. Yak-9U SSSR, G.A. Baevski (19 victories), March 1945 - Germany
4. Yak-9U SSSR, 3rd AE, 43rd IAP, May 1945 - East Prussia
5. Yak-9P SSSR, Maj. Viktor Kalashnikov (15 victories), 291st IAP, 1946 - Germany
6. Yak-9P Yugoslavia, “white 34”
7. Yak-9P Poland, “white 211”
8. Yak-9P North Korea, “red 3”
9. Yak-9P North Korea, “black 32”, 1950 -Kimpo
10. Yak-9P same aircraft, but with American insignia and number T2-3002
11. Yak-9P PR China Airforce, “white 35”

Conclusion

What more could you want?

This is a first-rate kit that will build with ease in a very unique and most handsome model. Actually, the only issue baring it from across-the-board excellence is previously mentioned wing-tip affair.

This is also a mightily impressive premier for Scale Bureau. Makes me look in anticipation for further releases from this company…

To my knowledge Scale Bureau does not have international distributors yet, so I cannot comment on the price and availability of this kit. I am however convinced that it won’t take long for the hobby-stores worldwide to add this kit to the inventory. It definitely deserves it!
