Is that right? a 42 cylinder radial engine?

That's right Carlos, I've got a book on it which I bought from the Historical Aircraft Engine Society when I was a member.  The engine was built in two row, 14 cylinder modules, three modules making the 42 cylinder version.  The idea was so they could have engines of various power just by removing or adding a module, 14, 28, 42, 56 etc. all having a diameter off about 36".  Crankshafts and camshafts were connected with special couplings and it was liquid cooled, and each row of cylinders was lined up exactly in front of one another so the camshafts could be connected.  Amazingly, there one engine in existence, the majority of the book describing how it was restored.

What scale?  I have a 1/72 kit of one in the stash made by Xotic Kits and I believe MPM or Special Hobby do a 1/72 kit too.

Yep, a 42-cylinder liquid-cooled radial.

If you're going with wasp Major aircraft, don't forget the XP-72 from Republic, an evolved derivative of the P-47 (I wonder how it would've done with P-47N wings).

If you're going with wasp Major aircraft, don't forget the KP-72 from Republic, an evolved derivative of the P-47 (I wonder how it would've done with P-47N wings).

Is that XP Evan, not heard of a KP-72.  I've often wondered about the XP-72 with the wings of the P-47N, it's a good possibility it could've happen had the war dragged on into 1946 I think.

Yeah, should've been XP-72.  I'm rather tempted to do that cross-mix as a P-72B version, perhaps with a five-bladed prop to keep from having to go to the extra weight of a contraprop installation.

After seeing a photo of the P-51F (I think) with a five blade prop I think that would have been a real possibility.  When I got my CA-15 I noticed it was about the same size as the XP-72 or Martin Baker MB5 and I had originally fitted a Sea Fury prop and spinner to it, it didn't look out of place.  The CA-15 or the MB5 would be a good candidate for the R-4360 too IMO.

[kitnut617]

They're perfect as they are. 

I didn't say they weren't Lee     It just that the CA-15 was to get R-2800 originally but the supply of engines wasn't ensured so they went with a Griffon, and as the previous Martin Baker aircraft had Napier Sabres, IMO the MB5 was earmarked for the same thing, there's definitely room for it or any of the bigger radials.  I'd like to see some photos of your Centaurus MB5 though.

[elmayerle]

Well, since NAA is verified as having done preliminary layout work on a R2800-powered P-51 version, how about one with a R4360 and an extended rear fuselage (say from the F-82) for wieght and balance purposes?
