XF-85 Goblin in 1/72 scale using the MPM kit : kit review & building report
After the second world war the US Air Force continued to rely on large bombers and with the new Cold War, the giant Convair B-36 bomber was developed. It was thought that it needed a self carried defensive parasite fighter. McDonnell expressed interest to develop a small jet driven parasite fighter that was to be carried in s section of the B-36 bomb bay. Two prototypes were built and tested in 1948. To be carried with a B-36 bomber due to its folding wings, it could be entirely stored in a fuselage bay. Flight tests with a B-29 showed that the idea had a lot of practical difficulties such as a lack of fighter performance against possible enemy opponents as wel as docking difficulties and landing on a fixed runway was in fact not possible as it had no gear. The fight tests were quickly stopped after a crash landing on Muroc dry lake and the project cancelled.

"no, no, I wanted air in the tyres, not the fuselage.... "
|In 1/72 scale there is a model from
(kit no. 72042). It was bought for only 5 Euro's at a swap market. It has
about 30 short run parts but after some clean up with sand paper are not
bad at all and the fit is reasonably good. Some etched metal parts are
provided as well.
A vacuform canopy is provided and also a transport dolly for manoeuvring in the ground. The plane itself has no landing gear. The Propagteam printed decals are OK.
All parts were separated from their
sprues and cleaned up. Assembly is per kit instructions and straight forward.
The parts F1 and F2 seemed optional wing tips fitted later on during testing.
The overall colour is metal and the
II method was used here with ALC-105 "polished aluminium". This
requires first a base caot of gloss black, which was airbrushed with a
couple of extra gloss coats of Johnson Future
The interior of the XF-85 cockpit and hook bay in front of the windshield was painted interior green with black instruments and details. The pilot seat got some straps and painted medium grey with a green head rest. The canopy and wind screen fit was OK, closing the gaps with white glue. The few decals went on smoothly. A pitot tube at the wing tip was added made from a metal needle. Finally, the whole model got a sealing Johnson Future coat airbrushed on to it.
I found out too late that the canopy
can not really be set open. That would need cutting out the windshield
as well from the vacuform shape as well as its base uselage-frame, part
of which is in the transparant part. So you better to set the closed canopy
in place, fill the gaps and paint it silver. (it would be nice to do this
in the same colour as the ALCLAD).
The Propagteam printed decals of the kit are very thin, and each decal applied by sliding it off is backing paper after being soaked in water. The decals went on without problems.
The ground dolly was also assembled
and it requires some filling and sanding to get a nice result. I made the
dolly colour yellow but probably it should be black, being dark (black)
on pictures. I added some rods to get a correct 'sit" of the model on the
Now... I still have the large 1/72 Monogram B-36 kit.... put were to put it after finishing this big bird?
