Hi folks,

What about a 4 engined, stretched B-25?  Very crude rendition below:

Needs more tail (vertical and horizontal) just to keep things in proportion.  What about the gun nose version with four engines?  Might be able to carry a pair of 75mm cannons instead of one.

I like the look of it. Maybe too hard to keep the tricycle landing gear, though. I know "Rita", the giant Japanese 4-engined bomber, still had a nosewheel, but for some reason in your drawing it looks like it would have to be a tail-dragger.

>Needs more tail <

Hey, EVERYONE could use a little more tail!  :slow:

Crude side view:



A bit like an Four engined American AW Albemarle maybe...

First off, a real-life prototype, the North American NA-148 Executive Transport. I had trouble finding good reference for this aircraft as there are few Mitchell resources actually dealing with the subject.


And now, let's take a walk on the whif side... When Japan declared war to the U.S. in December 1941, North American Aviation figured it would be good to develop a medium-size, single-tail transport using the NA-40 Mitchell as a basis. They built a single prototype of the NA-86 Battlewagon and sent it to U.S.A.A.F. for trials. However, there were already plenty of Douglas DC-3s, and NAA's production capacity was needed elsewhere, with the Mustang and Mitchell. The Battlewagon was therefore rejected and returned to NAA, which cannibalized the airframe for Mitchell spare parts.

NOTE: the real-life NA-86 is unknown, one in a handful of so-called "charge numbers" that has not been identified by researchers; that's why I chose to use it for this imaginary aircraft, even though the number most certainly corresponded to a real project at the time.



Finally, the North American XB-25T Twin Mitchellwas done more for the laughs, really, as a gift to Tophe.

Bristol Hercules engines and suitable props
rather round vertical twin tails
Horizontal tail has significantly greater sweep and chord.
Side blisters and rear turret removed.
Conventional rather than tricycle gear.
RAF markings

The executive transport version or the "Battlewagon" is quite plausible (look at the distinct family ties between the DB-7/A-20 and the DC-5 (what few of them were made).  -chuckle-  I'd go one bit farther on the executive transport and put a private lounge back where the tail gunner would be on the bomber.

The 4-engined bird looks nice and I suspect all four engines forward of the CG would do wonders to make the tricycle gear work.

How about an uprated version with R3350s in place of R2800s?

Perhaps an "early" version looking more like a scaled up NA-40 with the glass nose and the big clear canopy?

Yes, it's an attempt to make a Mitchell take on Albamarle characteristics.

Several years back there was a Monogram 1/48 Mitchell that was converted to a turboprop ASW tail dragger on display at the Seattle Spring Show.   I swore there was going to be a time where I did a chop/channel job on the same kit.   ;D

That does not sound like a pretty conversion.  The B-25 always looked so modern.  I don't think giving it an Albemarle makeover and tail dragger configuration is going to do kind things to a B-25, aesthetically.  BTW, Daryl, I'd love to see a picture of that conversion for this thread if you can find one.

Cheers,

Logan

It would indeed be aesthetically a retrograde step.   :-)   But then again, many aircraft based whiffs regress when the knife hits the styrene.   It's just tough to pull off a cosmetic enhancement.
I'll see what I can do.   It will have to be pencil and paper as I have no pixel based capabilities or skills regretably.
On the other hand, I ordered in enough Mitchells so I can also do a version of the Battlewagon shown above.  That should be a step forward aesthetically methinks.   


Cheers,
Daryl J.

I remember seeing that what-if B-25 on the table at the Seattle show.  Painted up in a dark grey with red stars.  The builder did an excellent job of converting it to the tail dragger configuration.

Jeffry, that's the one.    MAD boom out the nose too if I recall correctly.

I thought the MAD boom was mounted aft.  Do not recall much sticking out of the front of the model save for the normal nose.  I recall someone mentioning in polite and casual conversation later about the model in question and that they had overheard someone telling their girlfriend/wife/daughter that as a pilot they had encountered that very same aircraft while flying in what ever branch of service they were in.  Not putting too much into that statement but it was amusing to hear at the time.

That's correct.   Wish dig. photography was available then, I'd have had a bunch of photos of it. 


Some years back someone on Hyperscale showed a 1/72 Hasegawa B-25 missing all aft turrets in SEA Vietnam paint.   That was cool too.

I was looking through my Detail and Scale volume on the B-25 earlier today and I suddenly got an idea!

Take the floats off of this and add them to a PBJ-1J!


Perfect for when those island bases don't exist or are out of commission.

Now that's an idea ---  :)  And you can buy a conversion set of those floats in 1/72

This DC-3 (C-47C) still exists and was at a Fly-In a few years ago.

Perfect for when those island bases don't exist or are out of commission.


That's the same as what I had in mind when I built this.

I remember that one Kitnut; friggin awesome!  Where can you get those floats and who makes them?  Are they atrociously expensive?  I have an old 1/72 B-25 in the stash.  Guess I'll add this version to this list since the floats exist.  Would look neat loading a torpedo from a barge while anchored alongisde a small dock.   Mmmmmm I'm really liking this idea  8)

C-47 float conversion can be got at the Big H'

http://www.hannants.co.uk/product/RVHP72094

The floats I used for my 1/72 scale Nottingham came from a 1/24 Trumpeter Spitfire Floatplane

Here's a couple of other pics of the C-47 floats used in a couple of projects
