Ki-46 III 'Dinah'

The Ki-46 III Kai air defense fighter was developed from the highly successful high altitude reconnaissance aircraft that was given the code name "Dinah" by the Allies. This occurred when China based B-29's began operating at high altitude over Japan. To convert the recon version into a fighter required removing the nose mounted fuel tank and installing two 20 mm cannons in the nose and converting the cockpit to a stepped glazing. In July of 1944 the Army added a 37 mm cannon in the space previously occupied by the upper mid fuel tank. This cannon fired forward and and upward at an angle of 70. Although flown primarily by reconnaissance pilots with little dog fighting training they were none the less successful against the B-29's.

The Kit

The Tamiya Ki-46 comes it a top open two part box with nice artwork on the top. Inside the box there are four plastic bags. All bags contain one sprue except for one which has two identical sprues. One bag contains the clear parts. The parts are molded in a light gray plastic and feature recessed panel and fastener detail. The control surfaces are fixed and the fabric on them is very nicely done. Looking over the main air frame surfaces the only defects I found were some very slight sink marks on the fuselage in the cockpit area where detail is heavy on the inside. These are so light I probably wouldn't try to fix them as they look very much like "oil canning". There is only the very slightest amount of flash on any of the parts. I did find some ejector pin marks, the most obvious were in the usual place inside the gear doors, there are also some in the main gear bays and on the bomb racks. The racks will be covered if you use the bombs and the others are light enough in my opinion to ignore unless you are just anal about such things. I always consider them as representing lightning holes. Although they are one piece castings the engines show a nice level of detail. The interior has a moderate level of detail that should be adequate for most. There are two crew figures included, both identical but are nicely done. All together there are 78 parts molded in gray. See photos below, note that the kit has two of the sprues with the propellers on it and the sprue with the fuselage halves has been show twice to illustrate the interior detail.

The clear parts are reasonably thin and clear although even being bagged separately on piece still had some marks on it. I'm hoping that a little buffing and some Future will take care of the issue. The canopy is made to allow both the pilot and gunners canopy can be posed open. There are a total of 12 clear parts. Se photo below.

The decals provide markings for three aircraft in two different finishes. The decals look thin for Tamiya decals but the instrument panel decal and the large meatballs with white surrounds are badly out of register. See photo below.

After Market Goodies

I plan to use the Eduard Zoom cockpit set [FE 266]to enhance the front office a bit. It has a color instrument panel and other black boxes, items that I always have a tough time pulling off and lots of levers, knobs and other tiny bits to test my vision and hand eye coordination. See photo below. As build time approaches I will most likely seek out a mask set as well.


This is yet another nice kit from Tamiya. If it has a weakness it's in the interior details which the review link posted below goes into in detail about. If the interior issues aren't a make or break deal for you, you should find the kit most enjoyable. Recommend for those of most skill levels.

The Build

Like most builds it starts with the cockpit. This would have been rather quick except for all the PE, I didn't think I would ever get all the levers installed.

Not quite as much to be done in the gunners location.

Once everything was in place the cockpit and gunners area were given a dark wash to add shadows and bring out the detail

The Eduard instrument panel makes the pit look like a jewel ! At this point the fuselage has been joined.

The engines were assembled, I was going to add some wiring but they sit so far back in the cowling it would be difficult to see. Since the cowlings had no bottom side color on them and the fit to the wing was so good I went ahead and painted them.

The wings went together without a fuss.

The wheel wells feature some nice structural detail but are a little shy on anything else.

Wings and tail planes were installed. The wing fit was excellent as was the tail plane fit.

Canopies were masked and installed and give a coat of the interior color. At this time the areas to be yellow were also painted.

Primary colors on top and bottom. Once that had cured the engines were installed.

The decals supplied with the kit were a disappointment. The white surrounds on the Hinomuri were not concentrically opaque which if installed on the dark wing or fuselage would have looked out of register. I replaced those with some from Techmod. These were better but not flexible enough to fit over the aileron actuators without splitting. I had to touch them up where they split. Next the unit marking on the tail started to disintegrate before it loosened fully on the backing and broke apart during application. I managed to save most of it but it resulted in another touch up job. The aircraft numbers were also troublesome. They look OK at a distance but don't stand up to close scrutiny. A sad end to an otherwise nice build. I keep the weathering to minimum as these aircraft were operating from their homeland and not subjected to abuse it would have gotten on a desert island. Anyway, here is the finished product...

This was an enjoyable kit to build, everything fit, very little filler was required and if the decals had been better it would have been near perfect in my book anyway !
