Killingholme Posted February 28, 2018 Share Posted February 28, 2018 (edited) Hi all, Does anyone currently sell a detailed aftermarket R-4360 Wasp 'Corncob' engine in 1/72 scale? Will Edited March 2, 2018 by Killingholme Link to comment Share on other sites More sharing options...
John Thompson Posted March 2, 2018 Share Posted March 2, 2018 (edited) I believe Engines and Things did one, but it doesn't appear in their current (January 2018) catalogue. Maybe you can find someone who has it and is willing to part with it if you ask in the right place - good luck!

Killingholme Posted March 2, 2018 Author Share Posted March 2, 2018 Thanks John. That's a lead at least! Will Link to comment Share on other sites More sharing options...
72modeler Posted March 2, 2018 Share Posted March 2, 2018 Will, Engines and Things did a very nice 1/72 resin R-4360- stock number is 72-003. It has all four rows and the accessory section at the rear. I have just one, and I was planning to use it as a master to cast just the crankcase and first row of cylinders, as that is pretty much all you would see behind the prop/spinner of the aircraft that used that engine. Unless you were doing a cutaway or model with the cowling panels removed, you wouldn't have much use for this casting. IIRC, John Adams of Aeroclub also did an R-4360 in white metal, but it just had the crankcase and 1st row. It is the fact that it has seven cylinders in each row as well as a very unique arrangement of the magnetos around the crankcase that seemed to make it so difficult for kit makers, as some cast it with nine cylinders, for example Special Hobby on their F2G's. Anyway, both items are long, long OOP, so I would think they would be hard to find. The Aeroclub R-4360 metal engine front stock number was EP064. You didn't say how many you need or if you need the entire engine casting or just the front, so you might be better served to find one of the Aeroclub engines and use it to make a master to cast as many as you need in resin. I have one of the Aeroclub 4360's but it's earmarked for my F2G-1 Corsair project. Roll Models used to carry the Engines and Things R-4360, but it's no longer listed in their current catalog. Best I can do- sorry! Mike Link to comment Share on other sites More sharing options...

Best I can do- sorry! Mike Cheers Mike, I'm doing a Valom XF-8B, and quite fancied showing off that huge engine. Perhaps I'll just put some effort in to detailing the front row and magnetos on the Valom plastic (which is very crude). Anyway, it looks like the engine installation on the XF-8B had a ducting to push the airflow close to the engine- so not much will be seen of the cylinders themselves- more the crankcase and magnetos: http://www.boeingimages.com/C.aspx?VP3=SearchResult&VBID=2JRSN2PHFPUW1O 1 Link to comment Share on other sites More sharing options...
71chally Posted March 2, 2018 Share Posted March 2, 2018 Don't know about a scale Wasp Major, but a couple of months ago I discovered that there is a real one in storage just two miles down the road from me. It is a thing of beauty! You are right about that ducting covering the tops of the cylinder heads. Link to comment Share on other sites More sharing options...

I still marvel at how Goodyear managed to stuff those into the nose of the F2G-1/2 Corsairs! The aviation history and traditions museum here at Lackland AB used to have a cutaway R-4360 that was motorized....impressive mass of reciprocating parts!

David H Posted March 4, 2018 Share Posted March 4, 2018 I can enthusiastically recommend Graham White's book: "The R-4360- Pratt & Whitney's Major Miracle". Fascinating reading about the engine itself, the planes that used it...and also a good dissertation about how radial engines evolved over the years and the challenges designers faced in order to extract more power from them. -d- Link to comment Share on other sites More sharing options...
Robertone139 Posted March 4, 2018 Share Posted March 4, 2018 That monster weighs 3,200 lbs. I remember well because they had one at the NMNA in Mainside NAS Pensacola when I was training in the TH-57, which maximum gross weight was....3,200 lbs. I have one of the Engines & Things ones BTW.
