Model Photography


Ha ha!  I just realized after typing in the title that this post will likely crop up on a lot of searches having nothing to do with 1/72nd scale aircraft or plastic models...er...never mind.

I've been struggling with photographing my models for the last few months.  Set up the booth and lights, take pictures, then tear down the booth and lights and pack it away.  It wasn't helping with my ability to post here as I would delay taking those photos until I could do a batch.

And then suddenly the quality of the photos was crap.  I mean the lighting was bad, exposure bad, focus poor, depth of field all out of wack.  You name it, it was not coming out well.  I also decided to start putting my builds on line as Works-in-Progress (WIP) and that needed a faster method of photography...too many folks online seemed to be able to quickly take photos (daily) and post them easily on the forums.

So I asked questions.  My biggest hurdle seemed to be hosting the photos.  I could host them here but I'm not sure how long Google will allow that.  I guess, technically, none of us really know how long any of our photos will be hosted given the fine print in the agreements we quickly click through to get on with our lives essentially say the hosting site gets to decide everything unilaterally in the future.  Whenever that future comes.

So I shifted into using my iPhone6 for WIPs and my trusty Canon DSLR (Rebel T3) for the final photos for this blog.  And I started asking for help.  Lots of help.

What have I learned?

Firstly, my background is not quite right.  Mid-blue.  Why mid-blue?  That's the color that came with the portable booth.  Then I realized my white balance was all off.  So I tried using auto white balance but that seemed to make it worse, not better.  Just to my eye, BTW...my wife couldn't see a difference.

I'm looking into a homemade frame made of ??? (PVC pipe from DIY store?) that I can attache a roll of white-ish barrier paper to.  The advantage of the DIY frame is that I can size it for my larger models...the Lancasters, Sunderlands, Liberators and Flying Fortresses.  I won't then be so afraid to build them given I can't photograph them.  Additionally, I can change the background out, if I want.

But until then, I'm watching Paul Budzik's outstanding videos on Photographing Models.  I've already created a gray card for standardizing my white balance for each session / model.

I've set my ISO to 200 to better balance speed and exposure.

I got a remote shutter release to eliminate camera shake.  Okay, turns out the shake is still there from the mirror moving, but I haven't yet figured out how to lock my mirror open.

My f-stop is set to 29 to create a larger depth of field.

I've moved my camera away from the model, and the macro-zoom allows me to frame the subject, capturing enough to allow me to crop it for display on this blog.

I'm still learning, but the photos have already improved.  I still can't move quickly, but it's better.

As for my iPhone6...I'm finding that a strong light on my work surface (already there for modeling) is "good enough" for WIP photos if I position the phone just so.

I'd love to have a dedicated corner of my work room just for photography, but that won't happen.  I'd rather have it for display at this stage.  There is a spot "over there in the other basement room" that would work...but my wife owns that room.

Thanks for looking...

NMF Spitfire

Spitfire F Mk VIII, 307th FS, 31st FG, Italy 1944


This may have been easy, but it still took me 3 months from start to finish!

The Subject


The 31st Fighter Group used Spitfires for hacks during the last year of the war. As I understand it, they were flying P-51 Mustangs and retained a few reverse lend-lease Spitfires for the squadron CO's (or Operations Officer I would presume) to run about the theater when a critical meeting of leaders was needed face-to-face.


"MX" was stripped of paint and unit markings were applied. In my view, it should have been given an aircraft-in-squadron letter or number, but apparently it did not. Maybe the only known photos are pre-application of that letter/number so we are making an assumption that it never had them. Anyway, that is what this subject represents.


I also wonder if the aircraft would have retained it's 20mm cannon. I left them on for this build because it was simpler. If they access to spares to keep the bird flying they probably had access to the appropriate ordnance.

The Model


This is the Hasegawa late Merlin Spitfire kit, in a "U.S. Army Air Force" boxing of the Mk VIII variant. Kit number 00723 from 2004. The sprues are engineered to offer a HF Mk VII, F Mk VIII, or an middle or late F/LF Mk IXc. This particular boxing did not have the VII bits in it, but had everything to build either the VIII or IX. These kits are quite expensive nowadays, unfortunately, as they suffer some inaccuracy and the Eduard Spitfires beat these kits hands down for both detail and accuracy.

I decided to start WIP stories for each of my kits, which I'll document on the 72nd Scale Aircraft forum instead of here. I will discuss what I've done uniquely about this kit.


I decided to attempt the natural metal finish on this model because I hadn't done one in years and even then it was simply paint the entire model a silver color. Lately I've been building models that required an aluminum paint over either metal or fabric, and some are in the queue that have both fabric and metal painted aluminum...and there is a difference in the tone. So instead of simply painting it all one shade of Aluminum I decided to get some of the recent acrylic metallic paints and give them a try.

In this case, I started with Model Master Aluminum enamel as the base coat. I then masked off areas that I wanted lighter and sprayed them Vallejo White Aluminum. Then I did the same for Vallejo Dark Aluminum. I had no idea "what" would be each shade but I decided to experiment a bit and try to be symmetrical. I knew the cowling got hot so wanted to make it darker, but otherwise kinda let my imagination go. After the White Aluminum I was quite pleased with how it was progressing and frankly if I'd stopped there could have been quite happy. So for the Dark Aluminum I hand painted a few removable panels as well as the cowling. Yuck! Way to contrasty and the look was terrible. After lots of contemplation I did a combination of misting lightly the MM Aluminum enamel over the cowling and then misting it over the entire model to "tone down" the effects. Voila!

Summary



I'm quite pleased with this model. Yes, it's not accurate but frankly the Hasegawa late Merlin Spitfires are extremely easy to build. As a kit they are great, if expensive. I got lucky and acquired mine online as part of a "lot" and got a few of them for about $3 USD apiece. That was nearly 10 years ago and now they fetch well over $30. Not worth it IMO given the much cheaper Airfix IX and the extremely high value for money for the Eduard kits. Since I have them, I'll build them.

Low and slow

Nakajima B5N2 "Kate" torpedo bomber, B1-310, Lt. Joichi Tomonaga, at Midway; 4 June 1942


This is the second half of a "dogfight double" by Airfix that I completed for a theme build focused on "Low and Slow" subjects. I tried the salt weathering method on this one, otherwise it was an OOB build.

The Subject


During the Battle of Midway, on 4 June 1942, a section of Kates attacked the USS YORKTOWN (CV-5). LCDR Jimmy Thach, the CO of VF-3 which was assigned to YORKTOWN, was part of the CAP and attacked the Gates. Tomonaga's Kate was one of those shot down by Thach that day.


B1-310 was one of a group of Kates assigned to Hiryu and participated in the attacks on Pearl Harbor on 7 December, 1941. These Kates were originally (factory) painted in Ameiro, or a caramel gray color overall just like the A6M Zeros and D3A Vals of the typical IJN pre-war carrier air wings. En route to Pearl Harbor the Kates were given a coat of dark green on their upper surfaces to help conceal them from above over the waters of Pearl Harbor. By the time of Midway, survivors were showing wear to the green paint, even though the underlying Ameiro was still holding up well. Factory new B5N2 aircraft by this time were painted green on their upper surfaces, and the paint was well adhered to the airframe, so these examples would appear much more homogenous in their paint schemes.

The Model


I've always wanted this aircraft on my shelf, and while I have an old Hasegawa B5N2 Kate it was made 25+ years ago and reflects not only my knowledge of IJN aircraft schemes but also the available knowledge in the modeling community. In other words, that old kit is in the absolutely wrong colors! I was able to find some photos from Nick Millman who graciously shared them and while it appears that B1-310 does not have any surviving photos, photos of similar B5N2's at the time have survived and indicate a rather natty appearance. This both gives me freedom to weather it as I see fit but also mandates that the ameiro color show through in that natty appearance or it just would not be right.


Construction was straightforward; with the new Airfix kits accuracy is quite good and the engineering is amazing. Unfortunately it really does mean the modeler must follow the instructions as fit is so tight that any mistakes will result in a very poor looking model. After painstakingly painting the cockpit interior all the right colors, I closed up the fuselage and not a thing was visible! The olive green used in the interior (Tamiya XF-71 Cockpit Green) is not dark, but with the small openings it all comes out as just a single dark shade. I did add seat belts from masking tape, painted a bronze green color to give it a solid contrast.

The basic ameiro color is described as "grey poupon" or a "brownish RLM02". Huh? I found a recipe using Humbrol paints that was well like by Nick, specifically 8 parts Hemp (Hu168), 1 part Khaki (Hu159) and 1 part Midstone (Hu225). Since I had Gunze Hemp, and Tamiya Khaki plus my own recipe for Midstone, I tried this mix and it came out to a yellow-brown RLM02, but I didn't want to quibble at this point. My color mixing skills are not yet where I'd like them and while I know I can add some color and get brown, I have enough pots of brown mixed from various shades of other colors. I don't need to risk making another...

After painting the model overall ameiro, I then glued the canopy on, applying Eduard masks (which are nirvana when it comes to painting a canopy like this one!) and then gooped some salt, dampened with some water, onto the top of the model. After it had dried thoroughly (it turned white to confirm it) I sprayed XF-11 IJN Green on the topside. I purposely did not spray it evenly. I also lightly misted the tops of the ailerons, flaps and elevators, and the rudder to ensure they were a different tone, being fabric. After the initial clean up of all the salt I realized one side looked like it had been mistreated so I reapplied the ameiro and salt and tried again. Much better.

The other colors I used were a mix of black and Gunze H77 tire black to get a "blacker blue-black" for the cowling, as Nakajima used a "blacker blue-black" than did Mitsubishi. For the metal interiors such as the cowling and gear bay I first sprayed aluminum and then lightly misted metallic blue. This color should be more green but I'm not prepared to mix up that color.

Decals went on fairly easily with Daco soft and sometimes Daco medium. I had to be patient because initially they didn't behave, but eventually with multiple applications they finally tamed. Then I coated it overall with a misting of micro scale satin to seal everything in.

Summary



This was a very easy build, and I thoroughly enjoyed it. I've got two more as well as the B5N1 with the earlier cowling. I'm looking forward to completing at least one with folded wings.

Space


This is not meant to be a show-n-tell of my hobby room, but a near term dilemma: how to display my models when completed? While I have many shelves, about half of them are filled with my stash. Yes, I could temporarily move them to a hidden closet somewhere, but I'm likely to forget about them. That HAS happened in the past!

So I was over at a friend's house lately and he was describing his philosophy on display: 1/72 goes on a stick, 1/48 on its wheels. But he does not mix scales on the same shelf or even the same cabinet. So as he approaches the same challenge of "where to display and how" his solution is to shift to a "1/72 on its wheels and 1/48 on sticks" approach. His idea is that he can fill in above the 1/48 scale subjects, and fill in below the 1/72 scale. What a brilliant idea!

I've purchased some acrylic rod in 1/8 and 1/4 inch diameters -- this stuff comes in 6 foot lengths! I also have some display stands I've picked up over the years just to have on hand for some projects I had not thought of yet. I now need to start planning for some "in flight" displays. As my Airfix Firefly V shows, one option is to ignore the cockpit and just paint the interior, the other is on my Airfix Spitfire VI, where I found a pilot and gave him a proper uniform.

The likely path forward is a mix of both, obviously, and I think I'll focus on cockpits only in the more modern kits that actually have a cockpit...presuming I have a suitable set of aviators to sit in the seats. Since my collection of kits is made up of about 50/50 old/new kits, that's not going to be that hard. I also have a bag of aircrew in various sizes laying around somewhere...

Sometimes, you just have to take it easy.

Fairey Firefly FR.5, WB351/202/K, HMAS Sydney, RAN, Korea, 1951-52


This was a "free to me" kit found on the spare parts table at a recent club meeting.

The Subject


The Royal Australian Navy had a few Firefly FR.5 aircraft just prior to the Korean war but these were in a modification program to upgrade them to FR.6 standard. So the Royal Navy loaned a few to outfit the RAN carrier HMAS Sydney. WB351/202/K represents just one of these Fireflys.


RAN aircraft support strikes against North Korean supply lines; I suspect this subject is supposed to represent 1 of the 3 Firefly's that supported the longest helicopter flight at the time. This was the flight of a USN UP-28 Dragonfly on a rescue mission over North Korea; the Firefly's providing escort to "Uncle Peter" which was rescuing a downed crew from a RAN Firefly and returning at their extreme fuel range.

The Model


This is an old kit. Very old...not as old as myself, but it was released in 1966 by Airfix as part of their "red stripe" series. That's about the same time I started modeling. Lots of rivets had to be removed and because the cockpit was sparse and missing some bits (hey, it WAS on the free/parts bin table) I decided to not only close it up but not put anything inside and just put it on the stick with a clouded interior.


I took 3 weekends of 2 hours each weekend to pull this one together. I did ensure alignment, cleaned up the seams and generally focused on fit/finish. I tried 2 new things for this kit: Hataka acrylics and "spinning prop" by simply filling the spinner. For that latter bit I wanted to see how it looked. I kinda like the look...

I had purchased a Hataka set of FAA paints consisting of Interior Grey-Green, Sky Type S, Extra Dark Sea Grey, Dark Slate Grey, Sky Grey and Insignia White. The verdict is still out from on these paints. I frankly like the colors and want them to work. I found these to be too thin to brush paint and too thick to airbrush. The package said they could do both well (first red flag) and the bottles indicate they are airbrush-ready. I had to crank the pressure up to 30 psi and add a drop of thinner to the cup to get it to spray through my Iwata airbrush. I plan to add some self-leveling thinner and experiment a bit before I give up. They covered well and were easily masked.

The kit decals were yellowed and out of register. So I found some roundels in my stash and masked off the stripes. Instead of printing a new set of WB351/202/K black on decal film I decided to try experiment #3...add a thin film of Microscale Decal Film to salvage the original decals. It worked quite well, however even with Microscale's decal set/sol they didn't settle down, so I hit them with a drop of Daco soft and they settled right down. As seen in the photos, they still cracked in a couple of places, but they don't look bad. The yellowing nearly disappeared against the Sky paint, however the camera seems to catch the yellow better than my eye did.

Summary


I had fun with this one. I have another kit in the stash, but overall it looks small compared to say a Spitfire. I would have expected a late war 2 seater to be noticeably bigger. The cowling looks like it could barely fit a Merlin, much less the Griffon they used.

That was easy!

Spitfire LF Mk IXc, MH712/WX*D, No. 302 Squadron, 1944


Too much has been written about this kit already. I figure it's my turn to gush.

The Subject


No. 302 Squadron was one of the first Spitfire squadrons to land at Normandy shortly after the invasion.  MH712 is credited as the mount of Warrant Officer Henryk Dygala, a Polish pilot flying with the RAF.


The timeframe is likely late Summer or early Autumn, as the upper surface recognition stripes of Night/White stripes have been removed per an order issued in late July.  This aircraft also has the later pointed rudder that was likely a recent upgrade as the aircraft was used for bombing as part of 2nd TAF.  Wing bomb racks are installed to carry a 250 lb bomb under each wing.

The Model


This is the Profi-Pack which contains the sprues for a late Mk IXc (but with all the bits for an early F Mk IXc), masks, and PE. Decals for 6 subjects. Enough spares to tart up at least two more Spitfire kits...

The most difficult aspect of these kits is one must follow the instructions to ensure one uses the correct wheel wells, landing gear and fuselage details for the specific variant being built. Order is somewhat important...you certainly can construct the wings before the cockpit bit don't attempt to insert the cockpit bits after closing up the fuselage. And you have to decide early whether the canopy will be open or closed; cockpit door open or closed.

The PE was not really fiddly. This isn't my first attempt at PE but in the past it was all very simple stuff, usually just one or two bits and paint it all after construction. This one is pre-painted and there are quite a bit of items to work with. It was time consuming but looked beautiful once done. Is it worth it? Not for me, as once done the model goes on a shelf and other than me knowing the details are there it's all not too visible. When I showed the model to my wife she didn't "see" any of it until I pointed it out!


Construction was quite straightforward. The plastic is crisp and hard, takes Tamiya extra thin cement well and it was no time at all I was ready for seam cleanup. Very little seam cleanup really. Mostly from my own mistakes. With more care on future builds of Eduard Spitfires they'll be cleaner.

Painting was typical for me and involved Tamiya paints, all airbrushed. First the White, then masked and followed by the Sky band, then the Ocean Grey, mask with maskol and then Dark Green. Pulled it all off, masked again and then the Medium Sea Grey. Pulled that mask off and then masked the Night stripes. Finally the Yellow leading edges. Cleanup where needed and after a long weekend the painting was finished.

Decals took,longer but were equally a breeze. They settled down with Daco Soft on a clear coating of Future. Wrapped it all up with a coating of clear satin and a model was in the done column.

Summary


A few modelers online have complained this kit is over-engineered and hence a difficult build.  I did not find that to be the case, but then again readers here will note that I like to tackle limited run kits occasionally and they certainly require me to focus a bit more on fit.

I do believe this is yet another kit that requires the modeler to follow the instructions.  Certainly until a few are under one's belt.  Just knowing which bits are needed for the sub variant requires some focus.  


I've got quite a few more of these kits. Royal Class, Mk XVI Profipack, Aussie Eight and at least 6 sets of overtrees. It's an enjoyable build, just enough to do to keep it interesting, but not enough challenges to want to shift it to the shelf of doom.

Where is my winning season?


Failures

Edit: I added photos as proof!

0-2...I've now binned two models after putting in quite a few hours trying to make a model out of them.  That's not like me, I typically keep at it until it's tamed and at least looks like something I'd put on my shelf.  Never a competition winner, but then again I don't build for competition; only myself.

The first one was a TBD-1.  Limited run kit from AZModel, the detail isn't bad and I've built some of their other kits, so figured it wouldn't be too bad.  I even bought a PE set for it that was pre-painted as a way to give a larger PE set a try.  I'd read a couple of online reviews that panned the kit, but that was mainly due to accuracy, not build-ability.

After getting the cockpit in and getting the fuselage together, which required effort but nothing I'd not seen in other limited run kits, I tackled the wings.  No much of a problem except one wing was slightly off in size as compared to the other.  I compared it to both the fuselage and the old Airfix kit (noted for shape accuracy) and it turned out the larger wing was in error.  Huzza! It's easier to remove than to add.

When it came time to marry the wing to the fuselage...not even close.  The problem was thickness, not chord (which was the earlier error I'd fixed).  I mucked with it for a week, and finally decided the only fix is to cannibalize the wing from the Airfix kit and conduct some major surgery...the wing break down is not even similar between the two kits.

After a week of evenings I gave up.  Nothing was coming together and the "shapes" just kept getting worse.  Not to mention fit.

The second kit was a SOC-3.  The Hasegawa kit.  I've build one about 20 years ago but it was before my rigging skills were developed.  Still on the shelf albeit in the "damaged" area due to moves; I may need to repair it just to feel good.

The problems are of my own making as they just don't seem to be challenges I should not be able to overcome.  One is short-shot struts.  I've got plenty of strut material and have scratched struts before so I'm not concerned with it, but haven't gotten that far.  The other is installing a resin AM cockpit.  It's a beautiful set, made for the SOC-3 and can even backdate the kit to a SOC-1 (slightly different IP).  My issue: I can't get it to fit.

Carving, sanding, even used a motor tool (low speed battery powered) and as the dust accumulates the space to fit it does not.  It does not help that the fuselage is warped.

To be fair, I have not actually binned them.  They are boxed and put away for a future attempt when my attitude is better...and if a better kit hits the market in the meantime they WILL get binned.  Life is too short...

So I'm rethinking my modeling objectives for 2017...after only 6 weeks!  I should work on easier kits and only have that one difficult (aka long term) kit in the queue, while all the others are simple and satisfying.  Hence, I've just finished a rather quick build of the Eduard IX, a simple build of an Airfix Firefly V, and started 2 Hasegawa VIII kits coupled with a comparison build against the Eduard VIII.  All easy, quick, and very enjoyable.

Now I need to photograph them and get them posted!

Resurrecting an old pile of plastic

Spitfire PR Mk IC (PR Mk III), P9385/76, Nr 8 Operational Training Unit, 1940-41


While looking for a "training" Spitfire I realized I had the remnants of my "bash a Va out of the Tamiya V/I kits" sitting in my junk box.

The Subject


I won't repeat the story of the Photo Reconnaissance Spitfires but in short, just as the war started the two PR IA (modified Mk I fighters) were used from French airfields to look at German forces during the "phony war" period.  Both were modified to PR IB (longer focal lengths) standard and then to PR IC (same cameras differently configured, more fuel) as now they had to operate from England.



During this timeframe the Photographic Development Unit (not yet designated the PRU) was experimenting with color to better "hide" the unarmed PR Spitfires.  Sky, camotint Blue (later aka PRU Blue) and camotint Pink were tested.  I've read that grey, white and purple were also tested, but no documentation such as letters or photos can confirm this that I'm aware of as I would certainly create those schemes as well.


The PR 1C was a modified F Mk I airframe; the guns were removed and the fighter (armored) windscreen was replaced by the curved PR windscreen.  The canopy was also replaced by the PR canopy with the teardrop "bubbles" on each side to aid in seeing the target.

In order to gain more range, two fuel tanks were added.  One under the port wing in a fairing and the other behind the pilot.  Because oil consumption demanded a larger oil tank the chin was enlarged under the engine to make room.

The cameras were in a fairing under the starboard wing to offset the fuel tank on the port side.

The radio was removed to save weight.

This particular subject is a PR 1C operated by Number 8 Operational Training Unit.  It was used to train potential PRU pilots in the steady use of the Spitfire, flying straight and normal in the face of attacks to ensure mission completion.

The Model


This kit started as the Tamiya Spitfire Vb.  I had attempted a modification to the wings to convert it to a Spitfire Ib.  I gave up when AZ Model released their Ib kit and threw the bits into my spares box as it was fairly crude looking.  When I decided to add another PR Spitfire to my shelf I pulled it back out.

The fuselage was essentially complete; the wings had major divots and waves where I'd attempted to sand, cut, fit and make the wing appear to be a "b" wing with fabric ailerons.  I sanded down the bumps and filled and sanded some more, filling and sanding some more (forget how many times I did this) and eventually had a smooth wing top and bottom and enough of the rib detail on the ailerons to call it "done."

I then pulled my Pavla PR 1C/G resin conversion set out and after a bit more cleanup attached the resin fuel tank, camera fairing and chin fairing.  Some primer and additional cleanup required and then I re-scribed panel lines on the PR wing.


The most difficult bit was the canopy and windscreen.  Until this point construction/conversion was really just "basic modeling skills".  I had to put some brainpower to the canopy and windscreen, because while the Pavla set is designed for the Tamiya kit, it did not fit.  The rear portion was too wide and the windscreen is shaped a bit odd.  Luckily the windscreen/canopy is separate from the rear fuselage cover.

My solution was to trim and sand the rear bit until it "fit" with a bit of imagination.  If I squeezed it, the hight met the fuselage spine and the width match the fuselage sides.  Glueing was done via a combination of super glue and Gator's Grip acrylic glue.  I glued one side with Gator's Grip, then after 24 hours of curing carefully squeezed the glazing until it all matched and then added superglue to affix it.  After an hour of curing I then added more Gator's Grip via a wet paintbrush (being water soluble until cured it can be wicked into some important areas).  Giving it a good 48 hours to cure, I then wet sanded it lightly until it was smooth, and then polished it until it was crystal clear.

Now for the obvious issue: fogging.  I coated the clear bits with Future/Klear and let that cure before I started and then "hoped" it would not fog.  It didn't!

Painting.  How to mimic that PRU Pink color, which is really just a dusty off white with a hint of pink to it?  I started by priming the model in Tamiya gray primer (on purpose, instead of white primer).  I then pre-shaded to provide some depth, using a red brown shade.  Then I began layering on the thinned Tamiya white paint (XF-2) that had two drops of red (XF-7) added to the 15ml tin.  After each layer, I put the model under different lighting (natural, sunlight, fluorescent) and repeating layering until I could just see the Pink.

With a blue background and fluorescent lighting, it's white.  The red completely washes out including the pre-shading, resulting in a very flat and white model.  But the depth of the color remains so it looks sort of "natural".  In sunlight it looks washed out but dirty and in natural lighting against a white background the red shows up and it's definitely a Pink Spitfire.

Decals are from the Model Alliance sheet on Merlin PR Spitfires.  Now out of print but can sometimes be found via shows or online auction sites.

Summary


I'm quite happy with how it turned out, especially the paint scheme.  I want to do one more pink PR Spitfire, the FR IXc which is what most people model.

Imperial Japanese Army Air Forces Trainer

Tachikawa Ki-55 Type 99 Advanced Trainer


While at MarauderCon 2016 decided to pick this kit up.  Only cost me a fiver and it was well worth it!

The Subject


The Ki-55 was a demilitarized variant of the Ki-36 light bomber.  Essentially the bomb racks and bombing windows were removed, and a second set of controls were put in the rear.  As I understand the history (and I don't know that much!) the IJAAF needed a trainer, and the Ki-36 was a good means of getting one with little development effort.


The Model


The kit had 30 parts and given it's from 1983 unexpectedly the panel lines were all finely recessed.  Construction was very straightforward and only took a weekend to get it primed and ready for paint.


I chatted with Nick Millman regarding the orange color, and his advice was to start with a color like RAF Trainer Yellow (Humbrol 24) and add RAF Middlestone (Humbrol 224) until it had a "khaki orange" tint to it.  It turned out I had those two colors and quickly had a shade that was not quite orange, but definitely no longer khaki.  With that in my mind I then mixed some Tamiya paints as I prefer working with those.


I also decided to take some license with the "cocoa brown" color recommended by Fujimi for the cowling and landing gear covers.  Instead of a brown shade I used a blue-black cowling color that all other Japanese aircraft of that period had.  My own opinion is the "cocoa" color came from the heating of the cowling from the engine.

For the interior I added masking tape lap straps for the seats, otherwise a simple interior olive green paint.  The small instrument panel I painted black.

Decals are simply 4 Hinomarus, the "trainer" character on the tail and the unit marking on the cowling.  Very easy albeit the Hinomarus were a bit pernicious and one cracked on me.  I was able to sort it on the wing and when it dried I couldn't see the damage.

Summary


Chatting wth Nick I learned quite a bit about Japanese orange colors.  Navy and Army were quite different, with the Army color more like a khaki.  I also learned quite a bit about trainers in general that I'd known existed, but never thought to investigate.

Upgunning the Spitfire

Spitfire Mk I, R6776/QVoH, 19 Squadron, F/S George Unwin, September 1940



The cannon armed Mk I has always intrigued me, so when I discovered the story, I had to model one.

The Subject


Soon after the Spitfire began production, the Air Ministry was keen on adding cannons to the Spitfire.  The reason was simple: all the other nations were showing off their new fighters with cannons!  Actually most only had mock ups of cannons, or larger caliber (12.7mm or .50 inch) machine guns.  Most still had basic rifle caliber guns as did the Spitfire and Hurricane.  Up until the Battle of Britain even Fighter Command was cool towards cannons, viewing the 8 x .303 inch guns sufficient to their needs.



The Air Ministry however continued to pursue the cannon.  The 5th production Spitfire, K9791, was removed from production and used for mock ups; based on this L1007 was then modified to allow for 2 x 20mm cannon; all 8 guns being removed.  This was as early as 1938; actual modfication and testing ensued into 1940, 30 aircraft being modified and fitted with the new armament.  The modification could be viewed as simply new wings (to some degree that's initially all it was) with a switch for the cannon on the control column.  The operational use required much more development to get the cannons to work properly and not jam.



The g forces during aerial combat flexed the wings of the Spitfire and while not an issue with the .303 guns, it turned out to be a major issue with the 20mm cannon.  For starters, the cannon had to be rotated to ensure they would fit with minimal bulges above and below the wings.  Then the problem of the drum remaining tight as it connected to the breech had to be solved, and finally what to do with the excess gasses and links/cartridges as it fired.

Ultimately these were solved into 1941 and to ensure reliability as a gun platform 4 of the .303 machine guns were re-installed for a 2 x 20mm plus 4 x .303in configuration.  This became the "b" wing configuration, the "a" wing being the 8 x .303 inch Brownings.  Due to the weight of the armament, the higher power of the Merlin 45 was preferred in the Mk V, so all Mk I and Mk II cannon armed fighters that remained in the inventory were upgraded to the Mk V standard, or reverted back to the "a" wing.

This particular subject is one of the first 30 conversions to the Mk I, which had only the 2 x 20mm cannon installed; the Brownings being removed due to weight.  No 19 Squadron, RAF was converted to the cannon armed Mk I in the Summer of 1940, at the height of the Battle of Britain.  Unfortunately, due to the regular jamming of the cannon they rarely got off more than a few rounds before having to retire from the fight due to an inability to fire their weapons!  While they continued to score kills, they were very frustrated and at the time had many of the most experienced and higher scoring aces.  They quickly reverted back to the Mk Ia but by the time they completed the transition to get back into the fight, the BoB was essentially over for the day fighter phase, the Germans having shifted their incursions to the night time.

Wing Commander George "Grumpy" Unwin, DSO, DFM & Bar, was a Flight Sergeant during the Battles of France and Britain, having shot down 14 enemy during his initial combat service.  The subject of this build was his aircraft during September, 1940.

The Model


This is the AZModel limited run "Spitfire Mk Ib" kit.  It is the same set of sprues as their Mk IIb, Vb and VI boxings, with the only difference being the instructions and decals.  All only offer the externally armored canopy and unfortunately only offer the later Mk III (aka Mk V) round oil cooler.  To properly model a Mk I or II from this kit an earlier Merlin III oil cooler (semi-circular) has to be sourced.

While technically a limited run kit, AZModel has done a great job of making their kits assemble like a main stream kit.  Flash was non existent and all the parts fit perfectly.  No slots or tabs are present for attaching parts, so care must be taken with alignment, but they do attach well.  I had zero issues with construction.

I sourced the earlier Mk I oil cooler from an Airfix Mk I that I had converted to a Va.  It fit perfectly into the location on the wing underside.



Painting was straight forward for this scheme:
  • Dark Earth -- Vallejo Model Color 70-921 English Uniform;
  • Dark Green -- Tamiya XF-81
  • Sky -- Hataka A026
  • Night -- Tamiya XF-69

The new paint I tried was Hataka's version of Sky. Not bad, it's a bit less intense than other paint makers' Sky and I like the color, however it doesn't brush well (likely I've not figured the right balance of thinner, retarder and flow improver). It airbrushed okay but I need to thin it a bit more which means I need to, you guessed it, find the right balance of thinner, retarder and flow improver.

I used the kit decals, but I have to say they turned out to be a bit translucent, and inconsistent.  The small sheet of stencils where dark and went on perfectly and the carrier disappears under a coat of setting solution.  However the markings, while the proper color, seemed "off" and upon closer inspection (ok, via my magnifiers) I could see the dots from the silk screen printing.  I applied them anyway and some looked ok and of course at arm's length (my standard) they looked just fine.  They also had a filmy residue that didn't seem to want to come off, but luckily when it dried it dried clear.  Ultimately the decals did not silver, so it looks ok but do not meet the quality of the rest of this build. Ah well, done and dusted.

Summary


I enjoyed this build and during construction decided to buy a few more in the Vb boxings.  Now they are hard to find but AZModel released a more modern set of sprues in their Admiral line and I hope to make one soon.  They say they will also release these with the later internally armored windscreen, and then I can begin easily modeling the later Mk Vb subjects.



Thanks for looking...
