The Cutting Edge 1/72 conversion I have of this was missing the inner nacelles, thanks to Greg I can now reproduce a pair and place the extra air intakes they have in their correct locations.  Then I just need to build it -----  :-X

There is a 1/48 conversion for sale on eBay right now.  It has been there for weeks/months now...guess why?

Boeing Model 413 which was one of the early explorations for what became the B-47. (Looks like a -29 to me though!)

Thought about a KG-200 B-29 .... Superfort shot down in European theatre or salvaged by Japan & sent across ....

B-29 with B-46 nacelles?   I think these nacelles are larger, though, so 1/100 B-29 with 1/72 B-46 nacelles?

Very tempted to build one of these.   BTW, here is the more detailed photo with caption:

Suppose the R3350 had been a bit more troublesome and the USAAF had gong with the W3420-powered B-39 (Allison had be this time debugged the engine design); how would the aircraft have evolved?  Would that huge Lycoming liquid-cooled radial (XR7755) have been used in developed versions?

Looking thru stash box of B-29 kits found three smaller (non 1/72) kits each their own scale.
Passing this along as FYI for you potential B-29 kitbashers.
> Academy-Minicraft   1/144   yep!
> Testors  1/130   picture attached
> Revell   ~1/118   picture attached   This kit usually advertised as 1/135, well it aint.  Measured fuselage and wing.  Come up with 117-120ish scale numbers.

Strewth, that was the second plastic kit I ever built, back in the mid 50s! I was in an RAF hospital and one of the other patients had the B-29 kit and wanted to build it as an RAF Washington, but camouflaged! So I offered to do it for him and it came out pretty good. It seems I started in the Whiff business at an early age. :)

Just loved the one I saw down at the Yuma Airshow (even got to see it flying two days later), one of my favorite aircraft and at least two of the 1/72 kits I have will be Washington B.1's

Odd thought hit me, how does the Centaurus compare with the R3350?  I'm thinking of a Washington B.1A or B.2 with Centaurus engines and 5-bladed props.

Well, the Vickers Type 'C' was to have six contra-prop Centaurus engines and it was nearly as big as a B-36, so four on a B-29 would very easily be possible.  The nacelles were very similar to the B-29's too --  I would say just a change of engine in the B-29 nacelle and you could call it good-to-go ---  :)  According to Wiki, there's only 1/2" difference in diameter of the two engines.

SIX Centauruses (Centaurii?)?

Just think of the oil trail behind the aircraft, someone would surely design a detector so they could find it without using their radar! :)

how does the Centaurus compare with the R3350?

From Wikipedia (so take it as you will):

R-3350-C18-BA:

Length: 76.26 in (1,930 mm)
Diameter: 55.78 in (1,420 mm)
Dry weight: 2,670 lb (1,212 kg)
Power output: 2,200 hp at 2,800 rpm (takeoff power)

Centaurus VII:

Diameter: 55.3 in (1,405 mm)
Dry weight: 2,695 lb (1,223 kg)
Power output: 2,520 hp (1,880 kW) at 2,700 rpm

Seems potentially like a good match.  Maybe do a Licence production version for either the UK or the Commonwealth?  Maybe a good selection for a RAAF ASW B-29 instead of the Lincoln Mk.31 - ditch the Turbo-superchargers if operating most of the time at low level.  Put a Mad boom out the back.

Which makes me wonder, how feasible would a "Double Centaurus" four-row radial be for an alternate B-50 powerplant?  Or perhaps a re-engining of BOAC's Stratocruisers?

Tails on bottom two B-29 look right for Rolls-Royce AE 2100D3 with 6-blade props powered B-29.

Evidently Bristol did work on a 28-cylinder design that used Centaurus pots, much the same way the
R-4360 was developed using R-2800 pots.

When my Dad was a crew chief on Hastings and Beverleys he used to say that a Centaurus had 10 more litres capacity, 1000 more horsepower and a million more oil leaks than a Hercules. I dread to think what a DOUBLE Centaurus would leak like!
