    Thank you. yes this kit has been very pleasurable. I'm amazed at just how quickly it is going together too. Today we have made some good progress on the 1 to 1 scale project too. I hope it will be completed soon.

    Thank you too my friend. I have made even more progress. Last night I built some things but the main event was spray painting on some of the basic colors.

    Tom Cleaver (@tcinla)
    Haha... You made me smile with that one about your wallet. I think you will enjoy it if you get one of these. It's been a complete pleasure so far.

    Thank you for the compliments. This kit is fantastic. I have been enjoying every minute of it. When you get yours, be sure to trim off all of the little sprue attachment points. The fit is that precise. I also like to assemble as much as I can before I start painting things. It helped on this kit because some of these parts are very thin, and prone to breaking when you cut them off the tree. The thinner landing gear parts are very fragile so take caution there too. Otherwise it's been smooth sailing.

    Once in a while you get a kit that seems to go together like this one has. So far, so good. No hiccups to mention other than the fragile thin main landing gear parts that take some time to make sure they are free of all the small plastic sprue tree attachment points. Now I need to find some wood to knock on... πŸ˜‰

    This is a very nice kit, and I think you could be right. I have started building one of their Heinkel -111's several years ago, then for some reason it got pushed aside, never to be worked on again. This kit is very similar to their newer He-111 as far as the interior goes. Thanks for stopping by.

    This one has some fragile landing gear parts. It's mainly the secondary bracing for the main gear. Otherwise it has been smooth sailing. As far as installing the landing gear after the engine nacelles are on, I don't think it's possible. I sent you some pictures on this in a text message.

    Please stay tuned everyone, for tonight's update will be a big one !

    Thanks ... πŸ™‚

    OK here we go... Let me start out by saying the colors I have picked for the interior is based on some facts that regard how the Japanese Army painted their aircraft in the late 1930's and early 1940's.

    These color choices may not be 100 percent accurate, but chances are they are very close to how this real plane "could" have looked.

    The clear Blue / Green "Aotake" color was introduced in the mid 1930's as a corrosion inhibitor in the Japanese aviation industry. It was used throughout the war in various places on Japanese airframes. It was a color that changed in appearance, based on exposure to the elements, exposure to engine heat and lubricants, and even on how thick it was sprayed on to begin with. It has been documented as a Blue, Green, or even a Yellow that was translucent in appearance. In most cases, it was a combination of it all.

    I chose to replicate the Aotake look in the bomb bays, inside the main landing gear wells, inside the engine cowlings and on the inside of the cowling cooling flaps.

    I chose to paint the rest of the fuselage interior using a Blue Gray color, similar to that which was specified for use in the crew / passenger compartments in Japanese Army aircraft during the early part of the war.

    These Ki-21 "Sally" aircraft were built by both Mitsubishi and Nakajima. There could have been a difference between the colors used at these two factories. I know there was some differences later on when these same two companies produced the A6M Zero.

    So what you see here is my interpretation of how this plane could have looked.

    Please don't think it is 100 percent accurate, as it may not be. Chances are however, it was very close to this.

    The problem arises when we consider where the Ameiro coating was used on the airframe. Sometimes a more typical green or yellowish green color could have been used too, in the same locations where the Ameiro was used in place of it.

    Enough rambling.

    Lets get on to the model.

    Here is how the Sally looks at the moment...

    Chuck A. Villanueva (@uscusn)
    I assembled the main parts of landing gear, the attempted to place the two main pieces into position while I was holding the engine nacelles in place temporarily. I didn't have any luck doing this.


    The front of the wing spar is where the main gear connects to.

    I could get this main part in place, but I had trouble with adding the retraction mechanism later. There was not enough room to do this. I think we will have to follow the instructions here.

    This is where the retraction strut connects.

    and this is how it looks connected. It is next to impossible to get it all done at the same time, even when the retraction strut is not glued to the main strut assembly.

    So I ended up gluing the main landing gear together, and placed them in position temporarily while the glue set up. These were only held in place by a friction fit, and were removed later for painting.

    This shows how the main gear look like at this point.

    Then I decided to build the rest of the bomb load. These will get painted Black soon, with some stripes added later.

    The props were removed from the plastic trees and prepped for painting.
    The engine nacelles were also finished up. I added the oil coolers and air intakes. The fit was spot on.

    The engine front and rear sections were glued together, as were the engine crankcase and ignition harness.


    I used some Molotow chrome, and sprayed it on the bomb bay. I wanted to have a nice shiny base for the upcoming Aotake colors.

    The upper interior of the engine nacelles / landing gear bays received the same Molotow treatment.

    As did the engine cowlings, bomb bay doors, and lower portions of the engine nacelles...

    The propellers were treated this way too.

    Then I mixed up some Clear Blue Tamiya paint. I lightly air brushed some on top of the Molotow. I deliberately didn't try to get a uniform appearance. More on that in a few. The engine nacelle on the right has been given a light coat of Clear Blue.

    The bomb bay doors were given the same...The part on the right side shows the before, while the one on the left is after.

    This shows the upper nacelle / landing gear bays in the same fashion.

    Then it was time to add some Clear Tamiya Yellow. I lightly sprayed this on top of the Clear Blue, making sure I didn't get an even finish. I wanted it to be variegated. This shows the completed lower engine nacelles.









    This shows what adding the Clear Yellow did. It gave it the odd custom mix I was looking for and added some Green hues to the mix.



    The landing gear, engines, and wheel hubs were then painted in a Flat Aluminum color.


    The final touch was to come back a last time and add some Clear Green in a few places. These pictures capture the look I was after. I think this is a very good representation of Aotake.

    This shows how the bomb bay looks. It looks darker because the lighting is not striking it at the same angle as in the other photos. It definitely has a Blue Green look to it.

    Now on to the interior.


    I sprayed the inside of the dorsal gunners position using a Blue Gray color. Oddly enough, WW2 US Navy Blue Gray is a decent match for this !

    The instrument panel was assembled and also painted in Blue Gray.




    as was the rest of the interior.

    I will be adding the small parts and some washes on here soon, so please stay tuned for updates.

    As always, comments are encouraged. Thanks for stopping by.

    So to answer your question about installing the main landing gear after the engine nacelles are on:

    I don't think it is possible. So I deliberately assembled the entire landing gear as the instruction said to do it. They were placed in correct orientation on the wing so they would dry in the right pose.

    Once these parts dried I removed them from the lower wing surface for painting. Now they will go back on, once I paint the compression oleo with Molotow, or wrap it with Ultra Bright Bare Metal Foil. Then the engine nacelles will be added next.

    At this point, the wings will be ready for the camouflage painting. I have done a mock up fit with the wing to fuselage joint. It looks as if it will not need any filler either. Time will tell.

    I am amazed at just how fast this one is going together. I hope it continues to go this well.

    Thanks again everyone, and comments are always welcomed / encouraged.

    Good night ...

    Very good progress, Louis @lgardner
    The aotake looks really nice and the base you used for that defintely helped.
    Very nice start on the interior as well.

    Thank you. I am very pleased with the Aotake and how it looks. I think this is my best attempt yet.

    Spiros Pendedekas (@fiveten)
    Your wait is over my friend. Thank you for the kind words.

    Please stay tuned everyone as I post up the latest progress.

    Hot off the press !


    The wings are almost done. Here are some detail photos showing what they look like at the moment. I also decided to pre paint the Yellow leading edge stripes on the wings now. I did this before installing the engines and nacelles.


    This is a head on view of one engine. I'll likely come back later and do an oil wash on it to make the details pop better. It looks decent as is now though.

    If you look closely, you can make out some of the Aotake color inside the engine cowling.


    This next photos shows the landing gear and the engine. I installed the landing gear as the instructions tell us to do. It went together perfectly this way. No filler was needed on the engine nacelles or cowlings. So far the fit has been spot on.

    I did have to glue the engine nacelles in place behind the engine first. This made a perfect fit. Then after the glue had dried, I pressed down on the rear portion of the nacelle, and the fit was spot on. No gaps or seams needed filling. I did have to take a few swipes with the sanding stick to remove the glue that squished out of the seams.

    This is a good picture showing the fit of the nacelle and engine cowling.

    This shows more Aotake and the main landing gear.

    This photo also shows off the exhaust pipe opening.

    This next photo is backed out a little and shows more of the underside of the wing.


    These last two pictures show the wings, and where they are at now as far as paint and assembly.

    I will be working on the interior of the fuselage soon. It shouldn't be too much longer and I can button it up too.

    As always, comments are encouraged.

    Thanks for stopping by.

    Great progress, Louis @lgardner
    I do like the idea to paint the wing edges already, a lot easier to paint them before mounting the nacelles.

    You got busy with this kit so fast I only now had the chance to see your thread Louis!
    Good work so far, and if I may add my two cents regarding the interior cockpit colour I would go for the blue gray shade also.
    The kit looks fairly detailed as it is, good to k ow it’s a pleasure to build.
    Looking forward to your next installements my friend

    For those interested in the proper interior color for the Ki.21, here is some info from Nick Mellman's "Aviation of Japan" site, which I would say is likely pretty accurate:

    "From 1936 the grey-blue paint was to be applied as an overall primer to replace aotake, sometimes with the addition of # 17 Faint Blue colour (Tan Sei shoku - 淑青色) as a middle coat before the grey green # 1 Ash Green colour (Hai Ryoku shoku - 灰緑色) was applied to external surfaces in top coats, sanded and polished. The whole interior, including the cockpit, was to be painted the grey blue colour and this was introduced with the Ki-15, Ki-21 and Ki-27. In practice this continued for the cockpit into the war years, certainly for early production Ki-61, whereas aotake continued to be applied to other parts of the interior. When the application of aotake to interior surfaces was discontinued in early 1943 in order to to speed production cockpits began to be painted in other colours in a more haphazard manner, including the # 1 grey green and another darker grey green paint similar to that used for Hayate propellers."

    "... the grey-blue # 3 Ash Indigo colour (Hai Ran shoku - 灰藍色) is similar to FS 36118 Gunship Gray, ANA 603."

    That sounds pretty close to the painting instructions I have been reading since my kit showed up earlier this afternoon.

    There is also this statement from a poster at LSP that the color is "similar to USN Intermediate Blue."

    FWIW

    Thanks for stopping by. yes this kit is a very straightforward build. Follow the instructions, and you shouldn't have too much trouble. I did deviate some, by not installing the ammo drums and other various bits on the sidewalls of the fuselage when they called for it. You can add them later with some care.

    Your color information looks just like what I saw earlier, when I started doing the research on this particular type of aircraft. Nick Millman has a TON of great information available on his website. I have had correspondence with him in the past, and he seems like a good fellow. He definitely knows his stuff when it comes to this. I hope to see your "Sally" soon. What scheme are you doing your in ?

    John vd Biggelaar (@johnb)
    Thanks for the kind words. Yes it was a whole lot easier to go ahead and paint the yellow leading edges now.

    Pedro L. Rocha (@holzhamer)
    Yes sir, this one is a great building model. It has gone together exceptionally fast too, which was not expected. I have been very busy with working on our home. A simple paint job turned into a major repair. Nothing is ever easy it seems. So I have not had too much bench time lately. So I have been making sure that it counts when I'm able to get some time available. Yes the Blue Gray color I used is very close to the original shade that was used on the interior. I found some really cool photos of a twin engine Japanese plane that was recovered from a lake a few years ago. It had the colors well preserved, and what I saw looked very close to what I have done here. I did something very similar, when I built up my 1/48 Fine Molds Ki-10 "Perry" biplane fighter. I used the same (or very close) colors when I built a pair of Hasegawa Ki-27 "Nate's". There is ample evidence out there this is very close to what it looked like.

    Only to have a working time machine. πŸ˜‰

    Thank you my friend !

    George R Blair Jr (@gblair)
    Thank you very much. Yes this kit is definitely one of their better ones. I was also very impressed with how things fit on their He-111 models. I have started one of their Do-17Z's, and it too seems to be a good one for building.

    Please stand by everyone, as I have made some good progress last night and tonight. I'll be posting the update with some pictures in just a few.

    Thanks !
