Back-story
In the late 1960s, the Republic of the Netherlands (that's a loooong back story which is in short that after 1945 there isn't any royalty left in the Netherlands) wanted to increase and drastically modernise their ways of controlling their skies, coast lines and territorial waters.
Not just for keeping the country safe but also to relay necessary information to other planes and ships and for better coastal cooperation with the neighbouring countries. Therefor, in 1970 a single secondhand E-1 Tracer was bought from the US Navy to try out the system. Besides being a little aged, the Tracer also was by far not roomy enough for all the needs of the Dutch air forces (Navy included). So in early 1971 aircraft manufacturer Fokker was asked to come up with a plan for an airborne early warning system which also could perform other tasks like coastal patrols, sub hunting and even some meteorological tasks, if necessary.
In 1972 Fokker presented an unusual plan for a prototype. Somewhere underneath all the changes, there was an F-27 Friendship hiding. But the appearane was something radically different. The fuselage in front of the wings was lengthened about three meters. This same length was taken off from the fuselage section behind the wings, so it kind of looked like the wings were placed further back. The tail end of the fuselage was tilting more upward, like cargo planes.
All of this, the longer forward fuselage and the shortened rear, was done to compensate for the weight of a very unusual tail section. The horizontal tail was transformed into a twin tail. The middle vertical tail was completely new in design. It looked like it was placed on the plane backwards. It was unusually large and on top it had a rotating radar dish, about 8,5 meters in diameter.
Inside the plane, the electronics would be state of the art. Dutch company Hollandse Signaal, a daughter of the Philips electronics corporation, was designing new equipment that fit all the needs of the military. Through a rear entrance in the tail, instrument racks could easily be removed and replaced with other equipment.
Although the people involved already knew about the appearance of the plane, the Dutch press was highly surprised. In 1974, when they saw it for real the first time, some even said it couldn't possibly fly. But it taxied to the runway and the new, powerful engines effortlessly made the plane take off. Besides, the big dish had a lift factor that more or less cancelled out its own weight after takeoff, so it practically wasn't there in flight. Impressed by the performance, the military ordered Fokker to proceed and placed an order of four machines for the Dutch air defences.
Noted, the US. was in the final stages of development of their E-3 Sentry, based on the old Boeing 707. But since this still was awaiting results and would be considerably larger in size and price, the Dutch military was very keen on buying these smaller, yet hypermodern AWACS of Fokker. Also, the Dutch government saw a lot of export potential in this aircraft. Fokker spent the next year building and testing the planes. It was approached as a completely new airframe, because of the radically different structure. However, most of the flight characteristics of the trustworthy F-27 still were there and the test trials were completed much quicker than expected.
Since the F-270 Skyguard, as the plan was christened for abroad, was a lot cheaper than an average E-3 Sentry, and could offer significantly more room for equipment than the E-2 Hawkeye, the plane created a market for itself and got a lot of attention at the airshow of Le Bourget in 1975, where the Dutch air force demonstrated the second prototype of the F-270. It still had the agility of the regular F-27 and flew a couple of demos that deeply impressed the military brass that was there. Fokker got its order book filled quite well.
In the early autumn of 1977 the first batch of 3 planes, all sporting the same dark grey-blue livery, was delivered to the Dutch Navy and Air Force. Y-0001 and Y-0002, managed by the naval forces, were stationed at Den Helder and Valkenburg, the two naval airbases along the coast and Y-4709 was flying from Volkel AFB.
This was my first idea:

In the next post, the build report.
The model
Ever since I saw a photo of the magnificent looking An-71 Madcap, I had a weakness for this weird configuration of Dish-On-Tail AWACS. For this model I used an old 1/94 Revell Fokker F-27 kit I bought for just €1,50 in the thrift shop. It already was partially assembled and painted but I could take some parts apart again because the glue used was of the brittle yellowing kind.
(https://i.imgur.com/TfdPPFy.jpg)
(https://i.imgur.com/4mCssUa.jpg)
This is the first model I was going to cut and saw in pieces. I was very curious on how I'd manage. For the tail section I used the tail of a paper model Madcap as a starting point.
The plane's scale, it is the silliest thing. It was mandated by the box. It had to fit in this standard box. So why not 1/94? Being a paper model builder, I was lucky enough to be able to print out parts of models in any scale I desire, so that Madcap tail was not that hard to obtain in 1/94.
(there is a great model of the Antonov in paper.)
(https://i.imgur.com/Rl4mslt.jpg)
With the fuselage temporarily closed with sticky tape, I started hacking away. This was the first time I did a thing like this and I was quite anxious to just mess it all up here.Using a little saw, this eventually was not as hard as I thought. Some sanding and readjusting later and the plane was in three pieces. Nose section, wing section and tail section. The wing section was further cut back to almost the rear ends of the wing root. Then it was sanded so that the tail part would end up pointing slightly upward and the top line over the plane would appear almost straight.

The wings were modernised with an early type of winglet. I don't really know whether it would have made any difference in real life but I thought it would look good. I knew Fokker was experimenting with winglets in the late 70s so I thought let's just go for it. The winglets originally were the stabilos of an 1/72 Bell X-1. The horizontal tail of the F-270 got vertical end tails added. Leftovers from a 1/48 Grumman F4F Skyrocket. I cut them off a bit to blend them in better and sanded away the visible ribbing.
(https://i.imgur.com/CQRJf1a.jpg)
I initially was hoping to find some modern 1/96 Hercules-y propellers online to make a modernised, upgraded version, but of course 1/96 already is a deviant scale size, let alone 1/94. So no success in that and I left it like it was.
(https://i.imgur.com/TG9Xnge.jpg)
(https://i.imgur.com/6ZWaRFo.jpg)
The tail end and the wing section went together and of course needed a lot of putty-sandpaper-putty-sandpaper work to become smooth and seamless. The transition from wing to hull was extra tricky because of the short distance and slight change in curvature in the hull. I then made a new scratch-built extension to go between the front end and the wing section. Two bulkheads, small strips of plastic placed as staves of a barrel glued around the two. Then a layer of thin plastic sheet over the top to make the hull smooth again. It sure needed a lot of sanding, puttying and sanding after I glued it to the wing section. Lots of hours later it finally started to look like I wanted.

(https://i.imgur.com/WA9Rpab.jpg)
The cabin section was filled with white Milliput. Very old putty. Ancient, I might say. It was close to unusable. I put it in my microwave on defrost for a few seconds to make it kneadable again. (sparks!) But in the end it wouldn't harden any more. Oh well. It didn't matter anyway, I used it to put extra weight in the nose section (by adding a large nut I had laying around) and to seal it all off. The windows in the fuselage had to be covered with something I already had in mind but now really came in handy.
(https://i.imgur.com/f9sbSSZ.jpg)
(https://i.imgur.com/K37TfZk.jpg)
Now then, the tail. I hacked off the unnecessary bits and pieces. I placed a brass rod at the location I wanted the rotating axle to be. Secured it into place with thin plastic.
I took the Antonov tail, which I printed out on regular paper. After a quick fit, I redrew the outlines to fit the base of the tail section better. After a couple of fits, I had the desired shape and cut it out of plastic. I had some of the original 1/96 Revell Saturn V skins still in my spares box (I used stiffer and unprinted plastic for the Saturn) and this was flexible enough, it seemed. I also carved some panel lines in the tail to make it look more interesting.
(https://i.imgur.com/W9YJhzs.jpg)
(the upper part of the stabilo opening in the tail needed to be lower (that is what I meant with 'top lager' in Dutch.)
(https://i.imgur.com/Dz3fNF7.jpg)
(https://i.imgur.com/IKYytaq.jpg)
Fitting, readjusting, fitting, tinker tinker, and then I glued it to the tail section. The fit was almost perfect. The transition to the fuselage in front of the tail took some trial and error in paper before I cut the definitive shape out and glued it to the rest. Then of course, again, primer, putty, sanding to get rid of the seam between the tail and the fuselage. In the end I solved this by glueing a thin strip alongside the tail's bottom. it looked cool enough so I left it there as is.

(Look! I made a helicopter! (-; )

test fit of wings etc.
The cabin part was carefully lined out and glued to the rest of the fuselage. Again the tiresome sanding process began. I lost the windows in the process, they were damaged by the sanding. I'll try to replace them with krystal klear windows later.

And then there was the quest for a dish. I tried to make it by using the tested paper model method of flat cone-shaped rings but it was a real pain in the butt to get it right. Then after some rummaging I found the plastic screen of an old wind-up alarm clock I already had disassembled for the sprockets. The glass was lens-shaped an had the perfect diameter. Yay! I used a more thorough type of glue to stick it to the plastic base circle and with a couple of thin strips of Evergreen styrene around the outside and some sanding it started to look the part.
It now is too dark to get good pictures, so I'll leave that up to tomorrow and thereafter.
Hope you like it so far!

Glorious! Keep going :thumbsup:
What a brilliant idea. And looking good too.
That's looking REALLY good, and totally bizarre as well. :thumbsup: ;D
That looks really good :thumbsup:

Great idea, on several occasions I have used the 1/72 Hasegawa Grumman E-2A Hawkeye rotodome fixed atop of the vertical tail fin of a C-130, C-160 , BAe Nimrod and Breguet Br.1150 Atlantic. Through trial and error I have come to the conclusion that a metal pin is needed, to slot into a drilled hole in the vertical tail fin to fix the rotodome in position as it will break off if moved.
Great work!
Interesting. Looking forward to the rest. F27 doesn't get enough model time IMHO. :thumbsup:
Interesting idea.
The fin does look a bit oversized (compared to e.g. the wing root).

And that also is correct. But it adds to the grotesque look I wanted to achieve. It had to be almost ridiculous. Besides, with the rotodome (thanks for the right terminology, McColm!) on top, it already looks a little bit more in shape, yet still bizarre.
Thanks for all the kind words, folks! I like this kind of destroying of a perfectly good little kit a lot. This actually adds some creativity into plastic model building. Something I have always found lacking in just OOB building with even lots of after market detail sets. It just costs more than 10 times as much as paper modeling. Two new rattle cans, putty, the percentage of leftover paint I still had, the percentage of all the plastic doodads I added from other kits... But I still enjoy myself a lot! ;D
I'm speechless with wonder and want.
The rotodome is ready. I used, like I already wrote, the glass of an old alarm clock. I am not sure if it really glass, it was glueable, anyway.
I used some styrene strip for the rounding of the outer rim of the dome. Lots and lots of sanding, primer and sanding. I had to take all the old primer off and re-primer the dome when I finally sprayed the dark blue colour on it, because every scratch in the primer layer would have been visible.
(https://i.imgur.com/tQSR3Du.jpg)
(https://i.imgur.com/zTbmlzt.jpg)
Like McColm said, I had to use a long piece of brass rod for the dome (and I already incorporated a brass tube in the tail) but I discoveredeither the tail or the angle of the brass tube wasn't straight and when the dome rotated, it left a gap at the back of the tail. Not nice. I improvised a small tail extension. That did the trick.
(https://i.imgur.com/jNyopSB.jpg)
I of course took care to line out the extra extension with the tail. But not yet on this picture.
(https://i.imgur.com/VaYdKbN.jpg)
A quick test with the dome on the tail and the wheels loosely inserted in their slots, showed the F-270 wasn't tail heavy. Great!
(https://i.imgur.com/5V57Yxz.jpg)
(https://i.imgur.com/0dY8B0H.jpg)
Now it's time for the last doodads and H-tail extensions. I am working on the decals and with this dark blue colour I am intending to use I think the black lettering won't be visible. Time to order a white letter decal sheet, I think...
I'm chuffed to bits that you have taken my advice, great build so far :thumbsup:
Well, just in time before the festive days ahead of us, here's the final chapter in the build of the F-270. The rotodome went all right. (McColm, although yoy were chuffed and all, I already had made the full struture of the 9 cm long brass tube and inserting rod for the dome before I posted here...) I still question the material the dome is made of; whether it's glass or perspex of some sort, I don't know. It isn't heavy anyway so, that is nice. The 270 is no tailsitter.
After some experiments on test models, I decided to do the belly in flat Tamiya sky grey, but that meant I had to do it with a hairy stick. Oh well. A teeny tiny little bit thinned with water and it got on all right. The top was Tamiya AS-8 (US) Navy Blue from a rattle can. The wing's leading edges were given a black layer of paint.

Up next, the decals. I used all sorts of bits and pieces left over from previous builds in several different scales. I used a couple of black square patches to serve as dielectric panels (?). I also found a couple of red lines to become the warning lines for the propellers. The plane might be a bit menacingly dark but I decided to give it the full colour decals and signage, no toned-down greyish ones. Oh, and I used krystal klear to replace the destroyed plastic windows in the fuselage. I was a little sceptic at first but when it dried, I was very happy with the result. They really are nice little transparent windows now.

The Skyguard's belly in sky grey. The long pod under the belly also has a nice white line running over it. To do whatever such a white line is capable of in such a position on a plane like that. It's very handy. No, really, it is. Ask the pilots. They know. I think.

Grr. An angry looking military City Hopper with a dish on its overgrown tail.

There's this little story next to the cabin window. It seems to be a very funny one but it it too small for me to read. There is also one on the other side. That too is illegible. I guess it's the scale.
(https://i.imgur.com/dhLdoO2.jpg)
Some more detail shots.
(https://i.imgur.com/BqIy2cR.jpg)
There's a couple of doodads and whatchamecallits underneath the wing. Measuring or detecting stuff, I suppose. Air, Smells, Ingenuity, Humor, Measles, Dog hair, Ambiance, Pockmarkedness, maybe some of it, maybe all of them, who knows what these spying planes actually measure? Quality?

Luckily, I also found a decal of a door in my stash. Convenient, to say the least. The thorough sanding kind of erased the outlines of the originally present door and I am not that good a scriber guy. This decal will do fine. Yes, it tore in two when I applied it. I tried to 'repair' it as good as possible and it is just on these larger than life pics that you can see it. This is the only decal that had a little silvering but not that obviously present. I used micro set and - sol for the allpying of the decals.
(https://i.imgur.com/aJQVNh2.jpg)
So there you have it. I might re-visit this thread in the not-so-distant future to add a planned big decal on the dome. I first have to print them, and I am not that good in getting these self-made decals off of the carrying paper. It takes loads of patience and careful fiddling. We'll see. This is the result for now.
Like I said, normally, just building a plastic model kit doesn't do much to me creativity-wise, but reshaping it like this is actually a lot of fun. Just a tad expensive if you don't do it regularly and you have to buy new paint.
I hope you like the end result. I do, actually.
Cheers and have a nice time the coming couple of days!
That's absolutely bonkers, and magnificent as well. :thumbsup: :thumbsup:
The Tornado has some serious competition for the 'Mighty Fin' title there. ;D
Great build :thumbsup:
Fantastic.
:thumbsup:
Just a thought, maybe for the next one, but with a tail mounted radar like this would it not be possible to use the radome housing at the horizontal stabiliser?
Make it more of a broad oval with elevators at the back and fins on the end?
Turned out very nice indeed. Another great F27. I might copy your idea in 1/72 as I have a spare Friendship waiting at the moment. :thumbsup:
Oh that has come out well :thumbsup:
Thanks for all the nice comments, folks!

Hi Zenrat, your suggestion actually is a nice what-if idea. But I based my configuration on the An-71 (https://www.google.nl/search?client=firefox-b-ab&dcr=0&biw=1295&bih=658&tbm=isch&sa=1&ei=k_RAWof7E9HUwAKrz5_QDg&q=An-71+madcap&oq=An-71+madcap&gs_l=psy-ab.3..0i19k1.17370.25226.0.25512.14.14.0.0.0.0.89.804.14.14.0....0...1c.1.64.psy-ab..0.7.443...0j0i67k1j0i8i30k1j0i24k1.0.ztXWrrBMVa4) Madcap, which actually has this exact tail and its horizontal stabs just where they ought to be. If you look at all the other pancake carriers like the E-1 (https://www.google.nl/search?q=E-1+Tracer&client=firefox-b-ab&dcr=0&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiM-uDomaXYAhXMhrQKHZGNC_AQ_AUICigB&biw=1295&bih=658&dpr=2) Tracer, E-2 (https://www.google.nl/search?client=firefox-b-ab&dcr=0&biw=1295&bih=658&tbm=isch&sa=1&ei=IvRAWoLBOYOlwQLxrq_IDg&q=e-2+hawkeye&oq=E-2+ha&gs_l=psy-ab.3.0.0i19k1l4j0i5i30i19k1l2.86621.87306.0.88313.4.4.0.0.0.0.71.247.4.4.0....0...1c.1.64.psy-ab..0.4.245...0j0i30k1j0i30i19k1j0i8i30i19k1.0.3u61IpXoDGE) Hawkeye and E-3 (https://www.google.nl/search?client=firefox-b-ab&dcr=0&biw=1295&bih=658&tbm=isch&sa=1&ei=fPRAWo-dBMXTwAKm_46wDg&q=e-3+sentry&oq=e-3+sen&gs_l=psy-ab.3.0.0i19k1l5j0i30i19k1j0i5i30i19k1j0i30i19k1.20772.21434.0.22610.5.5.0.0.0.0.84.324.5.5.0....0...1c.1.64.psy-ab..0.5.322...0i8i30i19k1j0i8i10i30i19k1.0.zOwLf-eHtY4) Sentry, they all have kept their stabilos. I presume that the rotation of the dish is one factor, the E1 had an internal rotating radar and it still had quite a large horizontal tail, supporting part of the dish. It also might be just a little too much extra stress on the dome, to double up as an effective tail. I assume it had to be kept ultra light and therefore quite thin. It also would be housing the mechs for the tail movement, which might interfere with the radar reception. Fact is , the lift factor kind of cancels out its own weight in flight.
Oh, yeah! like it very much i've got to admit.. :wub:
Very madcap like yet very original with those gasturbines! Glorous!

I really like this, military turbo props are a favourite of mine and this is brilliant.
