Hi Holger, yes it's an Aires cockpit. I thought the fit was pretty good, I was able to make it fit by using sandpaper instead of an industrial grinder. You do have to remove the cockpit rails (where the canopy attaches when closed) from the kit plastic. But that's OK since they are depicted with more detail in the resin.

Sounds good! I purchased the Verlinden Updatekit for Cockpit and gunbay etc. . I hope it will fit as good as the Aires-ones. Your way, painting the "office" is very pleasing to my eye´s. Hang in there, it will surely become as good as your Lightning! Or better...?😉

I try to make each model as good as I can, I don't usually compare them to each other. On this one, I need to replicate the nasty weathering that you see on the F-14s with the TPS camo scheme, but with the addition of special squadron markings that are freshly painted. I think it will be an interesting contrast! I'm going to try to do the weathering primarily with post-shading, so there will be a lot of airbrushing required!

Almost ready for painting! My, what a pig this kit has been. Tons of flash, lots of warping, bad fit, and half a tube of putty (exaggeration)! The moulds have not aged well...

I've added some photos of the fuselage as it comes together. It's easy to see all the filler that I had to use (it's red). I also had to modify the wings, as Hasegawa only made provisions to mount them forward (with slats and flaps down) or with slats and flaps up in the "oversweep" position. By cutting an angle in the slot at the hinge point of the wings, I can now vary from fully swept to oversweep. The photo shows in fully swept position. Methinks it's starting to look like a Tomcat! Anytime, Mate!

Hi Marek, thank you for the link to the article on salt weathering. I would love to give this a try, but I am concerned that in 1:72 scale the salt crystals will be too big (all of the grey planes in the article were 1:32). I wouldn't want an exaggerated effect. But I will have a look at the salt that I have in the cupboard and see how big the crystals are. The results on the Tomcat and Hornet in that article are amazing!

Hi Philip and Holgar, yes I needed that much putty! I was quite disappointed in the fit of the model. I suppose we can blame the flash on moulds that are 20 years old. But my experience working with companies that do injection molding is that the warping comes from taking it out of the mould too quickly. In any event, it is together now and the putty has done its job. I did some painting last night and all of the seams are nice and smooth.

Hello Scalemates!
I've added quite a few more photos to my 1:72 F-14 build that document the salt weathering technique that Marek was so kind to bring to my attention. I think the photos show what was done, essentially you dissolve crystals of salt with warm water all over the model to create a random, patchy "mask" that you then paint over.
Once that is done, the salt is removed and you are left with a paintjob that would be very difficult to make using an airbrush or conventional masking. I then sanded everything with 2000 grit paper, and did a burnt umber wash using oil paints.
Still lots to do - this isn't over yet! Cheers, Bill

Thanks for the comments, mates! Michael, the F-14s from the 70s and for most of the 80s were in the Gull Grey over White scheme. These were glossy paints, and did not seem to weather like the TPS low-visibility scheme where all the paint is matte. I've noticed the same thing with the Phantoms, Corsair IIs, and Skyhawks - the old Gull Grey over White always looked pretty clean, but when they switched to the TPS low visibility schemes they start to look all patchy. Presumably it's a combination of salt spray from the ocean and sunlight that causes this. It's not just the sun, or else the F-15s etc. would also weather that way. But they don't!

Philip - I was scared too. Actually terrified is a better word. But it turned out to be very easy to do. The whole procedure, from wetting down the model and applying the salt, to applying my burnt umber oil wash took about two hours. Cheers, Bill

I've added another photo that shows the current status of my F-14D Felix after the markings have been applied along with a couple of coats of matte varnish. Next up is to do some post-shading and weathering with pastels. The burnt umber effect got amplified with the matte varnish, and now looks a bit too "burnt umbery" for my tastes, so I'll try to tone it down.
@Michael, absolutely true for the USN birds. I don't see that effect much on the USAF planes that use the same colors. There must be something else that causes the USN jets to look so nasty all the time. I figured it was the salt spray, but that's just a guess. Does any of our Scalematers know?

You may notice that the salt weathering effect was reduced from the matte varnish, too. It's still there, but not as noticeable. Hmmmm...

Hi mates, I've uploaded some new pictures taken after having a go with the pastels for the final treatment. I've managed to get rid of the brown tint to the burnt umber (what was I thinking in the first place - LOL) and in the process smoothed the edges between the different colors left by the salt mask. Which is not a problem, I think it looks better!

Thanks, Michael. I wasn't happy with it as it was, the only thing I could try was pastels, and they really did the trick. This was my first time with the salt trick, I think it would be more effective on 1:32 scale kits.

@Guido, don't be afraid to point something out if I've cocked it up. I'm a big boy! I was a bit surprised at how much the matte varnish affected the appearance. It toned down the salt effect, and really amplified the burnt umber. I used the new Alclad Flat, which I like because it seems to dry dead flat. It was the first time I used it over this kind of a wash. But now I know, and I don't have to bin the model! 🙂

Hi Bill, that new Alclad Flat, does it smell as "good" as their metal paints or can you blast it around uncontrolled without poisening yourself and the neighbourhood? Does it need thinning?

@Wilfried, no thinner required. Shoot straight from the bottle after you shake it up really good (the matte agent settles out really fast). Doesn't smell like their metallic colours, but it is a lacquer. Not like their new clear gloss, which is aqueous, and that you don't shake or stir at all.

I finished this baby last night - tonight I will set up the photo booth and take some new pictures. I think it came out pretty good - although I personally don't care for models with extreme weathering (unless it's a tank).
This was the first time I put a crew in an airplane - imagine that! Do you know how difficult it is to paint a five o'clock shadow on a 1:72 pilot figure? I used figures from a company in Belgium, PJ Productions maybe? They are very nice indeed!
Plus, I had to scratchbuild a US flag. Really a different job for me, starting with the salt! Cheers, Bill

OK guys!! I've uploaded the pictures of the finished model. Quite a few of them, too! I hope you like the way I posed the model - it represents what was typical at the end of an air show performance. The F-14 would "bow to the crowd" by "kneeling" on its front gear, and the RIO would wave an American flag. I love that stance when the F-14 compresses its front strut, it looks like a cat ready to pounce! Enjoy!

The configuration, you see is as a "showact" at special days. Judging from the nozzles with enough thrust to let the frontgear "collapse".!

The reason that you usually see one exhaust nozzle closed and one open when the F-14 is parked is because they shut down one engine when taxiing after landing. So they just need to remember which side to stick the flag out of of. 🙂

I've seen pix where the left side is closed, some with the right side closed, some with both closed, and some with both open! But the left side does seem to be the most common. I suspect they shut down the one that gave them the most trouble during the flight! 🙂

OK, here is the "official answer" (it's the same for both TF-30 and GE-110 engines:
The Tomcat has a "weight on wheels" switch and a "weight off wheels" switch. When weight is "on wheels" (on deck) the nozzles are commanded open to reduce thrust produced by the engines to keep from blowing over ground personnel. When the weight is "off wheels" (airborne) the nozzles will close any time when being in "basic engine" from idle to military power (highest thrust without selecting afterburner) and will open up as afterburner is staged. This feature gives added thrust at idle when being airborne. The switches are mechanically operated by the main landing gear scissors assemblies, but need electrical power to function. When electrical power is taken off the jet completely, the aircraft will default to the weight off wheels condition where the nozzles close so that if there happened to be a total electrical failure airborne you would still have the same amount of thrust at idle that you always do airborne.
When the engine is shut down, the starboard engine is always shut down first. The reason why is because there is a bidirectional pump that has to be checked to ensure that if the starboard engine is lost in flight, the flight side hydraulics will still operate. Once it is ensured that it is working the bidirectional pump will be secured and the flight side hydraulics will go to zero and the afterburner fuel control on that side will no longer be powered because of the lack of hydraulics. Since the weight on wheels switch is still receiving power from the left generator, the starboard nozzle will be trapped open. When the port engine is secured the left generator drops off-line at approximately 55%, however the combined side hydraulics will still operate at 3000 psi for a short period of time as the engine continues to wind down. When the port engine is secured (power off) the nozzle closes because of loss of electrical power and residual fuel pressure through the fuel control to the nozzle actuator.

So my model shows the engines at idle (both nozzles fully open). Highest thrust without reheat is with the nozzles closed (this causes the exhaust gas to speed up to fit through the smaller opening - like a rocket nozzle).

Once it is ensured that it is working the bidirectional pump will be secured and the flight side hydraulics will go to zero and the afterburner fuel control on that side will no longer be powered because of the lack of hydraulics. Since the weight on wheels switch is still receiving power from the left generator, the starboard nozzle will be trapped open. When the port engine is secured the left generator drops off-line at approximately 55%, however the combined side hydraulics will still operate at 3000 psi for a short period of time as the engine continues to wind down. When the port engine is secured (power off) the nozzle closes because of loss of electrical power and residual fuel pressure through the fuel control to the nozzle actuator."
Ok, thats a good explenation for that question!🙂🙂🙂Intersting to hear, that this is general for ALL versions!

I love the F-14 so much, but there are still so many questions and "walkarounds" to make...

It becomes more and more obvious why these machines are so expensive...
Thankfully they do not scale down the prices of the kits to the same amount. Imagine a 1 Billion Dollar plane in 48th scale would cost you 20833333 Dollars... augh !
I wouldn't have a stash of a few hundred kits and probably collect cigar bands or other useless junk
Anyway, thanks for your explanation Bill ! 🙂

Hi Scalemates! My salty Tomcat model received the most votes in the Britmodeller F-14 Group Build! Woo hoo! I won a set of USN Squadron patches. Many thanks to the nice folks on Britmodeller who donated the prizes!

I could not imagine what salt use will bring on a plane ( i mostly build Tanks,whitewashes with Salt are often).But now i know it.
Grrrrrreat!Congrats,too!!!

I don't know, let's see...Wiki says the F-14D is 19.1m long. Multiply by 1,000 and you get 19,100mm. Divide by 72 and the answer is 265mm. That's my answer and I'm sticking to it! (Divide by 25.4 for inches - about 10.5) 🙂

This is so cool. I like teh F-14 anyway. I like the pilots with the American flag. Nice little detail.

Thanks @Christian W - I added the pilots and flag after I saw a photo taken after an airshow performance where the crew displayed the flag and lowered the front gear as a "bow" to the crowd. When I saw the photo I said I gotta do that!

Album info
This is for a GB on Britmodeller, and I'm going to finish this kit in VF-31 markings for 2006, either the CAG bird or the CO bird. I'm using the Hasegawa F-14D kit, plus the Aires resin cockpit set. For now, that's all the aftermarket, but there is always the possibility that I may add something else.
