Just st wondering about Hasegawa P-47 kits

[Reuben L. Hernandez]

Been seeing OYOY5 request thread  about trying to get a M model.

 

Was just wondering other then the tail filet and I believe the crankcase what are the visual differences between the kits? 

 

Thanks

The P-47M is just a late Block P-47D with a more powerful C-series R-2800 engine that had a distinct bolted crankcase.  If you look at the Hasegawa P-47D-30/40 and P-47M kits, the only difference is the crankcase sprue.

Things like the tail fillet and underwing compressibility flaps were also late D model features, not M specific features.

 

Not really clear why the M model has such mythic status.  Only 133 were built, it was only used by the 56th FG (the only P-47 group in the ETO by that time- almost everyone else swapped to Mustangs), and although mainly developed to counter the V-1, by the time it entered service most of the V-1 sites had been overrun and the threat was minimal.  It was a hot rod, to be sure, but as far as effectiveness, it was probably most useful as a springboard to the long-range P-47N.

It probably has to do with the  decal sheet in the 'M'  boxing. Only thing not in any other boxing.

I don’t think the C-series crankcase in an any other boxing either.  It’s on its own mini-sprue and wouldn’t be applicable to any of the other boxings.

Must be the mystique of the 56th FG and the unusual paint schemes

So, what I'm reading is that if the crankcase difference is hidden inside the cowling then there is no real issue painting a D up as an M?

It’s not all that hidden.  The different crankcase is pretty noticeable when viewed from the front, I think.  It’s fairly big, too big to be hidden by the prop, and usually painted gray so it stands out against the much darker engine.  How important the difference is up the the modeler.

 

This is is a standard B series R-2800 with the bullet shaped crankcase.

This is the C series with the fatter cylindrical crankcase with the heavy bolting

Another option is to look for a resin engine with the other crankcase... 

[mhorina]

Vector made a resin WW II engine series that included the P&W R-2800 type B/C (late) .  It contains the bolted crankcase. It is Vector # 32-002

Sorry for the error ,corrected by Dave Williams, in my earlier post'

I believe Cutting Edge did, too.

Great thread!  I am much more greatly edgamacated.

Techmod set 32012 has 56th DG decals. So, with that set and a resin engine, building a M is easy. 

[Rick Griewski]

Excellent, I have the engine and now I just need to buy the decals.  I built this variant  in 1/48 scale many years ago.  The color sceme is one of my favorites along with the checkered cowls.
