I received for Christmas the Naval Fighters #41 on the Grumman  F-111B. I
have been thinking about building a model of one for several years and
recently bought a 1/72 Hasegawa FB-111A to form the basis of the model.
The book covers the subject in wonderful detail though........... there are
a couple of points that I need clarification on, the first is probably quite
easy while the second will be fairly hard.

1) When the aircraft 152714 & 152715 were built the length of the nose was
increased and part of the fuselage reprofiled slightly, not a problem as a
drawing is provided in 1/72 on page 54. My question is, when the cockpit was
bulged upwards and the windshield angle increased, did the lower edges of
the cockpit glazing raised or left where it was?

2) Under the heading of Carrier Suitability on page 47, the book details the
changes made to the production aircraft 152714 & 152715 such as the changes
to the nose and on page 48 states that "The main landing gear installation
was changed to move the wheels eight inches farther aft...."
Can anyone tell me if the whole main undercarriage bay was moved or what
changes were made to effect the eight inch movement of the wheels?

Thanks in advance

     How good/acceptable is the '60s Revell TFX kit that would do
either? That thing has a very special place in my heart! I still have
the USAF one I built 30+ years ago & about 15 years ago got another I
did as the USN version.

You might want to see if you can pick up the old Revell TFX kit.  It had an
extended nose, different wing tips, etc.  They are usually pretty cheap and
could be bashed with the Hasegawa.  I wouldn't use it as a reference guide
though. . .  It may be correct, but back in those days they didn't change
the molds for slight variations so you can't count on the kit.

I think you missed the point Kurt. I am wanting to produce a production
example, the old Revell kit is of the earlier machines which did vary from
aircraft to aircraft. The Navy Fighters book does give a review of the
Revell kit and I would rather use the Hasegawa kit as it has the extended
wings and has air intakes near to the ones the last two airframes used.

There were NO production variants of the F-111B. Are you working
something hypothetical?
The Collector - 09 Jan 2006 15:50 GMT
There were actually TWO different versions of the F-111B built, as
weird as that may sound.

The last couple airframes of the prototype lot included some notable
changes.  The radomes were somewhat rounded on the underside near the
front somewhat similar to long nosed USAF types.  Most notable, but not
particularly obvious, is that the cockpit was actually raised a few
inches resulting in a different canopy profile.  All of this info is
included in Tommy Thomason's Naval Fighters #41 F-111B book (which I
don't happen to have in front of me at the moment ;^).

The B model was actually a modified F-111A that was in the TDT&E
program. The B model had the longer wings of the FB-111 but the nose,
landing gear and engines were different IIRC. The B also had the pods
next to the engines ending in points rather than cut off as on the
later versions. The F-111 wingspan was 63 feet and the FB-111 was 70
feet. The nose/radome difference is obvious. The B used the P-12
varient of the engine that had more power. Tail nubmers were
151970,151973 and 151974.

In 1/72 scale, Revell made two kits: H-208 and 5804. H-208 contained
parts for both A and B models.

Back around 1999, FOX 3 Studios (Gerald Asher) had an F-111B conversion
kit out for the Monogram 1/48 scale kit, IIRC. HTH

Somebody is always detailing some esoteric stuff like this over at
rec.aviation.military  --  so I recommend that you post this over there.
