Trumpeter 1/48 A3D Forward Fuselage

Kursad of Caracal Models posted pictures of the new Trumpeter kit on the ARC discussion forum: http://s362974870.onlinehome.us/forums/air/index.php?showtopic=264255&st=0

A few of the details on the forward fuselage seem a bit off to me:


Here is a photo of the forward fuselage of KA-3B Bureau Number 142244 showing the location of the ATM exhaust ports and the aft end of the IFR fairing.


The questioned raised rectangles on the belly are associated with the bomb-bay anti-buffet fence. It proved necessary to keep the bombs from rattling around in the bomb bay after release rather than dropping cleanly away. It was normally, but not always, extended when the bomb bay doors were open.
For some reason, there is a version of the fence without the outboard separated "finger". The oval opening is at the center line of the fence. On the left side there is a raised exhaust vent on the outer surface of the fence but I don't have a good picture of it at the moment.

Hopefully the Trumpeter kit includes a separate fence that fits over the raised rectangles.

Note also that the most outboard rectangular opening is there to expose the catapult hook well.

Here is a picture of the right side of a Bomber forward fuselage that illustrates a couple of nuances. It has both the early sextant opening on the right side of the canopy and the later "bubble" on the left side, which is not common. There are a couple of long narrow external patches on the lower side of the fuselage (the skin wrinkled noticeably there on the catapult stroke; you can see evidence of it here).

 The "button" on the tip of the nose was a sensor that provided total temperature to the "bomb director system".

Compare the picture above with one of a TA-3B, which was a Version, the nickname give to non-bombers.
That should provide some insight into the difficulty of establishing the correct configuration for a particular A3D, be it Bomber or Version. For a more detailed synopsis, see http://tailspintopics.blogspot.com/2010/09/mighty-skywarrior.html

More later, maybe...
