Mitsubishi R1M3 Kumorigachi (Broken Cloud)

[Bungle]

Now there was an experimental aircraft late in 1945 for the Japanese Navy, the Yokosuka R2Y1 Keiun (Beautiful Cloud). Like the experimental Heinkel He 119, the R2Y1  used  two engines to drive a single propeller. It also resembled the proposed Messerschmitt Me 509 and included a tricycle undercarriage.

In another thread I decided to turn the JoHan A6M2 Zero into a jet interceptor by adding the wings from the Revell ME P-1099. In doing so I had a pair of Zero wings and a P-1099 fuselage. Now that's temptation and as I fiddled around I thought.... it's a Keiun !

So here is my homage to the Tokyo'46 and Luft'46 What-ifs the Mitsubishi R1M3 Kumorigachi (Broken Cloud)

First off - the kit itself (at the top)

I've started the cockpit - its a two seater with pilot / other geezer back to back.. (bottom)

And here its in the fuselage

Here's the fuselage and wings

And the wings glued on (like with the Zero they are the same)

Finally (For the moment) I've added a couple of air scopes and exhausts plus I needed to extend the nose so I could get a prop spinner to fit.

This will be a good pair with your A6M12, yes, all inverted into a what-if couple, congratulations...

Great build, concept and name.

Interesting 

[PACOPEPE]

Very interesting japanese whif.

I chose one of the jet version of the keiun; with the engines inside the fuselage, and some modifications: one jet engine, swept wings and "T" tail. Is the "Yokosuka R2Y3". I put it as mother of the Kayaba Katsuodori (mistel). I´m going finish the combo next days.




How do you distribute the engines?.

Looking very cool so far

I like the concept. Is the fuselage wide enough for, perhaps, a Japanese version of the twinned DB-606 or DB 610, using the license-built Kawasaki or Aichi engines? Thus TWO rows of exhausts, etc? That would give it more power, presumably.

If conventionally-powered, the propshaft would have to be right between the pilot's legs, or, in whiff-land, below his legs and "geared" up to the propeller center at the front of the plane.

Ah but I'm thinking single engine with two contra-rotating props  (only because I can't find any matching exhausts in the spares box)

Well what's wrong with having something hot and throbbing between your legs ? Couldn't the pilot ride side saddle ??

The nose extension has lowered the center of the prop so it will run whiff beneath the cockpit.

The turbopro version of the Fw Flitzer (do a search, there's a drawing elsewhere on the site) has the extension shaft for the prop running beneath the cockpit and entering a gearbox to drive the prop.

Nothing "wrong" at all, but it seems to me that in your pilot's compartment the propshaft would have been "visible" and literally right between his legs---there is seemingly no room in your cockpit for that, unless my sense of parallax betrays me. That is, to my parallax vision of the pics you have displayed, if you put a ruler on an extension of the center of the "prop" back toward the engine, the line would run RIGHT UNDER (or through) the flat part of the pilot's seat and shaft and/or housing would be "visible".

[Bungle]>The nose extension has lowered the center of the prop so it will run whiff beneath the cockpit.<

OK, maybe my parallax DID betray me. Then there is the nosewheel bay that might "prevent" a "low" shaft into a proposed gearbox.

There ya go---RW "whiffers" got there first!! I hope there is room to squeeze it all in!!  Really I do!

>Ah but I'm thinking single engine with two contra-rotating props (only because I can't find any matching exhausts in the spares box)<

Yes, I have often had to match the enginerering to parts on hand! But I'm SURE that myself or others here would be glad to donate another pair of similar exhausts (or a set of four from something else) for such a good cause! Those exhausts LOOK like a Bf-109 set, or maybe Fw 190D. Name the plane and brand of model and you should be able to get a match for the "down low" exhausts *IF* you want to go that route.

But most of all, it's YOUR route for whatever pleases YOU, not me!

Sequoiaranger : Your comments are truly noted and I tip my hat (that's not me in RussC's picture - Slim Pickens, I believe, there's nothing Slim about me !) to you. I think the exhaust were from the KP S-199 so bf-109 is probably a very good spot.

I gave the kit a liberal splashing of Tamiya IJA Grey and added some logs. Not sure if the following photos will help in curing your parallax symptons

Still like the idea of the pilot riding side saddle.

I now see that the forward fuselage is "fatter" than I had first thought, but here are my thoughts:



The dark line I drew shows what I think to be the "thrustline" of the engine and "propshaft" to the center of the prop/spinner opening. To me, the line is high enough to be "seen" inside the cockpit, therefore my comment about "seeing" the propshaft right under the pilot's seat. The line also seems to line up approximately to where the crankshaft of the engine would be.  But, it seems to me that a "gearbox" at the front of the engine, and a similar gearbox (simple two-gear transfers, both) in the nose would allow the "shaft" to run forward a bit lower than the "line" I drew, and *PERHAPS* (the whiff-world being more forgiving than the RW) the propshaft could JUST FIT between the bottom of the cockpit and the top of the nosewheel-well!!! "Problem" solved!!  

Let me look in my extensive "spares" bin to see if I have a similar set of exhausts. If so (or you get some from someone else) I might recommend the second set RIGHT UNDER the trailing edge of the wing (lined up vertically with the top set).

If you are useing two boxes of gears to shift the prop shaft lower you could also shift it sideways as well
