Ta152C-1 Revisited

Recommended Posts

Hi Guys,

 

Pull up your armchairs for another long saga.  I finally finished the 1/32 scale PCM Ta-152C-1 kit earlier this year and it left me excited but disappointed as well, I just knew it was wrong in so many ways. So I've pulled out the second kit intending to tart it up a bit.  The basic kit will get a lot of rebuilt parts like guns, bits of undercarriage, things like that, some basic engineering to actually get the plastic to line up and then the big problem: The wings!

 

the cockpit during a test fit.  I thinned the seat a few years ago along with another 8 D-9 kit seat.  The usual plastic strips to align and locate the fuselage halves - no pins on the kit at all.

Some rudimentary research and a lot of guesses and here's the lower and upper wing changes I thought would be necessary.

At this point its too late to make suggestions!  This is the underside.

And the topside.

Underwing after scribing, filling, sanding and swearing a lot!

Part one done. Hope you like it so far

Here's part two.

 

The undercarriage on the PCM kit is fragile with poorly defined locations and fixings. Some points were drilled and 0.4mm brass wire pins added to locate things a bit better. Here are the actuators with drilled eye ends to fit on the pinned main legs.

The pivot posts on the spar were drilled and more 0.4mm rod superglued into place

Something like this?

One thing i realised was the radiator cowling was wrong and decided to do something about it.  The flaps overlap with small triangles - PCM has them in the correct locations but they are recessed and the should be proud.  Once you know this and look at all the photos again it becomes bloody obvious. No point in looking at the H as its a completely different radiator, cowling etc,

 

Radiator cowling assembled from the kit.  You can see the recessed triangles.

I added thin plasticard triangles that are just slightly raised.  They look thick because I've drawn a marker pen across each "Open" side so I didn't sand down the wrong part.

Very nice... not often do you see Ta152C build!  Are you sure the cowling triangles are raised?  I thought they were slightly recessed.  The photo is of a Ta152H-0...

OK.  Some basic facts.  That's a Jumo 213 with an annular radiator.  It came as a complete power egg with radiator and cowlings as a piece part.  190D series had a circular radiator.  The Ta152C series ran a DB 603 engine with a completely different radiator.  Still annular but the whole assembly is different.  The cooling gills are overlapping, visible in photos of 600 series in museums and if you look carefully at published photos is really obvious when you know what your looking at.  I haven't uploaded any from my iPhone to Flickr yet though.

 More tomfoolery with the Ta, this time the tail.  PCM gives plain butt joints, flat plastic to plastic for tailplanes to fuselage.  Not good!

My fix was to drill the airframe end of the joint with a couple of holes from the outside.  Then using a lot of skill and cunning (you won't say it so I will!) held the tail plane in the correct position and drilled back thru the holes into the flat end of the said tail plane. shove in some plastic rod, in this case 1.5 mmfrom Evergreen and we have a fairly secure tail plane.

Only a few minutes work but well worth the effort.

Hi Guys,

 

When it comes to the cowling, I spent a lot of time online and going thru books to see what is really there. I had assistance from Steve McCready in Australia and I'm going to use some of his photo revisions here.

 

Drawing from Hitchcock's book, Eagle Pubs.

A DB600 series cowling in a museum,  clearly showing the triangular overlaps.

Steve McCready's take on the above.  This makes sense now.

Another DB600 series engine.  The overlaying triangles are pretty clearly shown here.

Now have a look at this with fresh eyes.

Here's my modified cowling with gill 5 having two triangles.52155192865_4d56bf3491_b.jpg

 

Top view.  I still need to engrave lines for gills 1 and 10 just outboard of the gun troughs.

So that's the justifications for making the cowling the way I have.  If you've got better information, share it but don't waste time with pictures of the Jumo 213 and the Ta152H, it just isn't the same animal.

 

Regards,

 

Bruce Crosby

Thanks for the very detailed  explanation Bruce, much appreciated  - looking good.

 

@Thunnus I think the tone of Bruce’s response to your picture shouldn’t be construed as rude - he just knows what he’s talking about.

Not to jump in the middle, but its certainly possible to be both.
