Using Trumpeter P-47N engine for my Hasegawa P-47M hope it works

[oyoy5]

The Hasegawa M engine is incorrect per references and does not have the turtle shaped magnetos and trumpeters engine for the N looks closer and more detailed.

Or use the Vector engine:

You're correct that the Hasegawa M kit engine does not have the correct ignition system.  Having said that, the R-2800-57 (P-47M) does not use the GE turtleback ignition system, it uses the Bendix-Scintilla dual magneto system.  Substantial differences between the two.

The P-47N used the R-2800-47, 73, or 77.  The 47M used the R-2800-57 engine, as mentioned by Juggernut, however, so did the XP-47N. Most people alive could not tell  the R-2800 engines apart, you’d be safe using anyone, besides, the mechanics probably replaced bad engines with anything they could get their grimy paws on. But if you are picky, you might check out Engines and Things. They make great resin engines in 1/72, 1/48, and 1/32.

According to my reference, the following engines were used by the P-47N model:

 

P-47N-1-RE         R-2800-57

P-47N-5-RE         R-2800-57

P-47N-15-RE      R-2800-73

P-47N-20-RE      R-2800-73 or -77

P-47N-20-RA      R-2800-73 or -77

P-47N-25-RE      R-2800-73, -77, or -81

 

EDIT:  All the above engines are C series engines (bolted, circular prop reduction gearcase)

 

R-2800-57 equipped with Bendix-Scintilla DF18LN dual magneto ignition system

R-2800-73 equipped with General Electric magneto system (turtleback) ignition system

R-2800-77 equipped with Bendix-Scintilla DF18LN dual magneto ignition system

R-2800-81 equipped with General Electric magneto system (turtleback) ignition system

You didn’t mention the XP-47N, which did use the same engine as the P-47M. The three engines installed into the production P-47N were the 47, not 57 as used in the M, 73, and 77. I did forget the 81.

Another option i found is ordering the magneto parts sprue from the Tamiya Corsair, they look to be correct for the P-47M or at least close

Can you provide me a source for the use of the R-2800-47?  My reference does not list that engine as being used in the P-47N but does list the R-2800-57 (yes, the same engine as the M) in the first production examples of the P-47N (-1-RE and -5-RE).  As an FYI, the R-2800-47 is a B series engine with the bullet shaped prop reduction gearcase....All production P-47M's and N's had C series engines in them.

 

Other references that indicate that the P-47N's used the R-2800-57 (at least):

yes, the distributors from the F4U-1D (and also those in the F4U-1A later engine) are correct for the R-2800-57 engine.  You'll want to get the dual magneto as well as the one that comes in the Hasegawa kit is poorly rendered; very poorly.  Tamiya's on the other hand, is an absolute gem.

[Fred Jack]

It is listed in the catalog of engines released by Engines and Things. They state the 57 as being used for both the 47M and the prototype N. Right now I’m about 500 miles from my reference library, so I went on line.
