B-25R Mitchell
« on: August 26, 2015, 10:29:04 AM »
By the end of World War II, the B-25 Mitchell was still an extremely useful platform, but with higher-performing A-26s in service and B-42s on the horizon, large numbers of B-25s were headed for storage and disposal.  When new hostilities in Europe suddenly heated up, the decision was made to bring the B-25s out of storage and reverse the process.  To make them more effective on the battlefield, North American designed a four-jet engine installation (using Allison J-35s), replacing the Mitchell's two R-2600 radial engines.  Few other changes were made in order to keep the modification and testing program as quick as possible.  The first B-25R flew in June, 1946, and B-25Rs began to enter squadron service in November of that year. 

I got the 1/72 Airfix Mitchell as a prize from a previous GB (thanks, Bill!).  Since I believe in building what I have on hand, I chose that as my starting point.  The Smer Me 262 kits were the cheapest way I could get four jet nacelles.  I am slowly working my way through the design of the engine mount.  I chose to mount the engines in such a way as to preserve the original main landing gear installation, and they needed to project well forward to maintain CG.  I still have a long way to go to make it look reasonable.

This is going to look good! Maybe the US response to the  Russian Sukhoi Su-10. They tried odd engine placements as well as three jet pods.

There is no guarantee but I guess this 4-jet B-25 idea is probably a new winner... :-*
Congratulations (no matter the final result) ;)

Still working on the nacelles - lots of PSR.  Quick photo below shows where I am with that.  In the meantime, I have begun the interior and fuselage assembly.  Bought an airbrush today (my second one ever, and my first in twenty years - I had a very cheap Testor's one in the 90s).  Got it home, hooked it up - could not get it to spray color (or even water).  Can't figure out what's wrong.  It's a Paasche, but the cheapest one they make.  I'm returning it and I'll think about getting a better one.  In the meantime, I guess I'll press on with brush paint and rattlecans for now.

I have been inspired by your idea of a Jet-Mitchell, thanks!
The F-00 (aka B-25ZJ) was a secret fast reco plane, different from your bomber, as being a Twin-Jet-Mitchell, not Jet-Mitchell only:

I second that ---  :)

Now what would you do with the main u/c, I think I would go with something like what an XB-42/43 has, just a bit larger though

I always thought Tophe had something to do with the B-25 in SuckerPunch:

This was like my original plan.  The problem of main landing gear was the reason I changed to an underslung B-45 nacelle type of arrangement.

And B-25/B-45 both came from North American factory, yes? Your model is very possible, so interesting "could have been" thanks! Go on!

Well, it didn't come out quite as nice as I hoped, but I hope y'all like it nevertheless. 

Several version of the B-25 were converted into R-models, including glass-nosed B-25Js, "solid" gun-nosed B-25Js, and even a few 75mm howitzer-armed B-25Hs.  Different versions were given different block numbers.  Shown below is a B-25R-10, converted from a gun-nosed J.  All R-models left the factory in a bare-metal finish, having been stripped of paint at the conversion centers.

Good job at capturing B-25R in styrene :)
With no kits of the conversions available, you done us all a service by building this one.

Oh yes! I like this one a lot! Those engines give it a nice, predatory look and those nose guns sure would pack a punch!

Well done, Acree! It's nice to see you caught B-25 fever!
