Exaclty. There is a book called "Mustang Survivors" and it has a list of the P-51's that are out there. I think they even list the original source of the aircraft, and note that they are either replicas or re-builds of them. I had the book, and sold it, so I need to go to get another one, and check more details.

Mustang Spinners

I recently created an update/modification for the P-51D (bubble top) Mustang.
A new propellor Spinner...based on the Spitfire design.

The D-model spinner has always been a touchy subject.
Its a simplified design...only three actual parts (not including the joiner strips).

If you cut the parts carefully...assemble them cleanly and tightly...and do a little burnishing and shaping,
you can get a pretty good representation of a D-model spinner*.
*First photo...my best attempt at a D-model spinner.

But with only three parts...to keep the assembly as simple as possible...its not a perfect shape.
Its stepped shape is a little awkward, and if you don't achieve good seams, its got a very "paper model" look.



When I updated the B/C model Mustangs, I updated the spinner by resizing the spinner from my Spitfire models.
And I liked the result.
It has a cleaner slope to the curving conical shape.
Following photo is a Mk.III Mustang with a modified spinner from my Spitfire kit.



Recently someone had some trouble with a spinner on a D-Mustang build,
and so I have decided to offer up the same modified Spitfire spinner for the D-model.

I have correctly resized the parts to fit the D-model Mustang kit, and created a single download sheet
of modified spinners in various paint schemes (to match most of my P-51D kits).

The reason I didn't add this spinner originally (to the P-51D kit) is because its a little harder to build.
There are four parts instead of three (to the body of the Spinner)
...giving it a smoother transition of the curved shape.
But that is one extra part to assemble...and two of those parts are much smaller.
Especially the disc at the tip.

But with a little care and patience, it goes together quite nicely.

Download the update sheet at www.papermodelshop.com
...you can find it in the EXTRAS section.

So much better! Great revision Dave.

Thanks Tappi.

To be honest, the existing spinner is much closer to the actual shape of the D-model spinner.
Its the fact that it has only three parts and such an obvious staggered shape
which makes it look a little awkward.

This is an inherent problem with paper models, you need to add so many parts and sections
to get a smoother shape and transition...but then it becomes too difficult to build.

I've always advertised the fact that when designing a part, I always keep the less experienced
builder in mind, and I have a tendency to lean towards build simplification (over technical accuracy).

Anyway, I hope this modification will satisfy a few builders.

Some like smoothness over accuracy, some like ease of build when others might seek all the details as correct as possible. I like your design philosophy, models for the masses so to say. Not too complicated structure, accurate as possible and fairly easy to build. Now that you mentioned the new one does seem to be a tad too long and therefore the original is truer. Am I right?

You got my way of thinking!

No, I would say they are almost exactly the same length.
Pretty close anyway.
Its more about the overall shape and slightly different curve.

The Mustang spinner (real thing) has a slightly longer look to it.
And it depends what Spitfire you look at...some spinners are pointed, some are rounded.
Later model Spits had a more tapered, pointier spinner that is more like the Mustang.

.... finaly i got it, because operamini browser in mobile is blocking mediafire site.
i had to use firefox on my computer... and works fine.
i just noticed that your Mustang III RAF 316/315 Sqrdn (polish)1944, spinner are red n yellow (page8) but the cover pict are all white...

go the spinner mod file, resize it to match my  mustang raf 316 kit.. same size. looks good...  will build it after the marek kit finished.
Thanks Dave...

regards,
Loui

okay, I have NO explanation for this one!

The RAF 315/316 (Polish) Sqdn Mustang MkIII is supposed to have a white spinner.
The cover artwork has a white spinner.
I built this model...from my own kit...and it has a white spinner.



BUT...the final model PDF has a yellow and red spinner.
I didn't know this and I don't know why this is.

I have since fixed the kit and uploaded a replacement.
Obviously you can pull a white spinner from another kit...or from my spinner updates.
But you can also return to me or ecardmodels and get the updated kit.

Do I have gremlins?

I added a second page to this Spinner Modification download.

another 8 Spinners from other P-51D models.
This makes a total of 15 spinners, in various colours and patterns,
which should cover most, if not all, of my P-51D kits.

Anyway, still a single download, but now its two pages.
Hopefully some people will give the alternate spinner a try and show some photos.
Tell me if its better, worse, different?

This is a P51D update....but its more of a future modification.
I don't have immediate plans to update all the older kits with this mod...
but it will definitely be applied to future P51D releases.

I've never been 100% satisified with the way the Windshield attaches to the fuselage on my P51D model.

I admit, its an awkward area to recreate in paper, much like the wing root fairings, with some varying compound angles.
The lower windshield framework (on a real P51D) is part of the upper fuselage...its not a windscreen fastened on top.
After all the parts of the fuselage and windscreen are connected, the seams are filled with putty and paint to smooth it all over.



Its difficult to recreate this assembly without a lot of sectioned parts and pieces, especially at smaller scales.
So the common approach is the make a separate windscreen and fit it on top.



Unfortunately the exact placement of the windscreen (position on the fuselage and vertical angle) is left up to the builder
and can easily vary from build to build.
Even I have fitted a windscreen more than once, getting it into the desired position.

So, I have always wanted to play with this and see if I could come up with something different.
Not necessarily better...there will always be necessary seams and connections in paper models...
but maybe I could eliminate the guesswork of placement and position?

After a couple of tweaks, I came up with a way to fit the existing windscreen flush to the fuselage



I did have to modify the shape of the windscreen a little bit...I also added some lower length.
But the main alteration requires removing a section of the fuselage, and fitting a simple recessed part underneath the opening.
The windscreen now fits into the "hole", making its edges flush with the fuselage edges.
The shape of the opening also dictates the placement, shape and vertical stance of the windscreen.

I'm not the most patient builder, but the fit is quite good.
With some careful trimming and gluing, I think you could improve on this.





So, watch for this "update" to be applied to future D model Mustangs
and if I can find the time, I may modifiy some of the existing kits.
If you are currently building a D model and want to try this mod, just let me know what kit you are working on.
Send me a photo or two (so I can see your progress)...and I'll do up some modified parts for you.

I am working on some more tweaks for the B/C models, and I am going to try a simialr windcsreen modification to those kits.
