Radial Engined P-51R in 1/72 scale
« on: October 09, 2014, 06:08:24 AM »
The British Purchasing Commission was rightly thrilled with North American's NA-73X prototype, but a shortage of unobtanium, which was a critical component in both Allison and Merlin engine crankshaft timing rocker joints, put availability of these famous engines in jeopardy. Huge teams of scientists, metallurgists and chemists tackled the problem on both sides of the Atlantic to no avail.



Fortunately, the new Packard Chumpion 18 twin-row radial engine used commonasdirtium in its crankshaft timing rocker joints and production of the 15.83 jigawatt powerplant was assured in the new Packard Packing Works in Park City. North American went back to the drawing board. Thus the P-51R (R for radial) Stopgap was born.









The wicked fast and incredibly powerful new fighter outperformed even the most optimistic estimates during flight trials and both the R.A.F. and the U.S. Army Air Force placed large orders.









This would prove fortunate indeed. Not because the P-51R would win the air war, but because it helped win the propaganda war.



The famous "Keep 'em Flying!" poster would cause record levels of war bond sales and arms production. Today no museum worthy of the name fails to have one of these iconic works in its collection.



The poster featured the P-51R Stopgap flown by Lt. Col. Clarence Clearance, C.O. of the 235th Fighter Group based at Whatley Manor, Wiltshire. While this unit failed to ever see combat due to maintenance issues, its contribution to the inevitable Allied victory is incalculable.



No P-51Rs remain airworthy today and only a handful of airframes are left, but the famous poster is still seen on T-shirts and on college dorm room walls worldwide.

This all started innocently enough with the P-51 kit from the 1/72 Accurate Miniatures Air Combat Legends P-40/P-51 Bonus Pack kit.



Isn't that box art something? Really hits you where you live, don't it?

The P-51 kit is pretty basic, but one can make a very respectable model out of it. One with patience, talent & skill that is. Mine, well it has wings and a propeller. Speaking of wings, this P-51 kit is an oddball because it has elements of both a P-51 Mustang and an A-36 Apache in it. Most is pure Mustang, but the wing armament is four large holes which to me mean 20 m.m. cannons, typically found on the A-36. If one was masochistic enough to scratch dive brakes in 1/72, they could end up with a believable Apache out of it.

Right off the bat, I knew this one wasn't going to be OOB by a long shot. First off, I had to get rid of that ugly, drag-inducing belly scoop.





Yikes! Just look at that gaping hole! Fortunately, some card stock came to the rescue.



Next, time to amputate the now useless Packard Merlin. What good would it be with defective crankshaft timing rocker joints anyway? Mr Razor-saw, front and center!



Now, what to replace it with? An Amiot cowl & prop looked nice and a spare engine shaved down a little was a decent fit.



Wow that prop really looks winky! No help found in the bag of loose props, so I need to dress this one up a little. I found some styrene nubs that looked a little like counter-weights if you've had a few too many martinis and I added a new prop tip made from sprue.



Looks passable with a little paint.



Speaking of paint, here's the P-51R Stopgap all painted up, before decals. It was brush-painted by hand with acrylics, Model Masters OD and Dark Ghost Gray mostly. Poly-Scale Soviet Green was substituted for zinc chromate on the inside of the cowl.













Decals were leftovers from the decal dungeon. Those neat 1943 red-surround stars-and-bars come from a diminishing sheet by Eagle Strike.





Oh hey, did I mention that this kit comes with all the bells and whistles? No, not really, but there was a stand.



And here's a few shots of the P-51R Stopgap on that stand. You can practically feel the propwash, can't you?





I had a lot of fun on this project which took me three days to build. Don't get me wrong, while this kit is pretty simple, it builds up nice and no putty was needed. I did use a little white glue around the canopy, but that's it.





I hope you enjoyed the P-51R and reading a little more forgotten history.

I'll admit, this looks awesome.
Good job streamlining the rest of the fuselage.
The Radial engine makes for quite a drastic change for the Mustang!

Awesome job, Brian; complete with your usual enjoyable back story.  On a slightly more serious note, the four holes were for the 4x.50 cal. machine guns the P-51B/C carried; it wasn't until the redesign for the P-51D that they went to six machine guns there.  The real problem with unobtanium is that it's refined from costemfortune ore which is expensive to obtain.

Inline to radial conversion is smooth.  Don't look tacked on.  You have touch for such bashing :)
While doing that, a bit F6F appearance snuck in.

Not to mention that the raw costemfortune ore is often contaminated by Administratium... ;)

Hello? Am I still on Earth? No, it seems I am in Heaven in the clouds, with this wonderful P-51R model (of Brian) that cannot "exist" down there, so... here Above I may reveal the next step in the Mustang radial family: the liquid-cooled radials that were top-top-secret...

(Thanks again Brian for the inspiration...)

You have an outstanding talent for extrapolating and improving on designs, Tophe and I'm glad I could inspire you.

It'd be fun to see what kind of concepts we'd get discussing ideas.
