Starting build of Experimental Flying Wing Bomber (XFWB). Not pure flying wing only because has nose section. Is to be 1940-ish proof of concept akin to B-15 & B-19. Combining YB-49 and front of Ki67 because it has matching cross section height to YB-49 and is sleeky. Eliminating jet engines, replacing with puller props. Looking at engine possibilities so that is TBD. Building wing and nose first.
Attached pictures show jets cut out, filling leading edge air intakes, and start of filling openings in wing.
-
Looks promising!
Go, fins, go!

Going to be watching this one very closely Bill :smiley:
-
I love flying wings! Going to be following this one with great interest!
-
Definitely looking forward to this.
-
Thanks all,,, does build simpler than Mega-carrier, still it has nose section fit things to deal with. Plenty PSR.
Figured out different vertical stabilizers. Trying piston engine mounts, for swept wing..... they be asymmetric.
-
Progress --- Basic wing assembled. Doing PSR&R&R.... Three of six engines built. As seen in attached picture am going with four B-24 rudders.
-
I like those rudders.
-
Some possible inspiration - Boeing Flying Wing concepts from the mid 1930s. They are all variations of the same theme and come under the Model 306 designation:

I like those rudders.
Me too! It's almost frightening how well parts that shouldn't belong there work.
Brian da Basher
-
Coming along nicely! :smiley:
-
That Boeing design looks like early B-17 cockpit, DC-3 wings and Allison engines....... Mucho PSR!!!
-
My first thoughts were B-15 ----
-
Those concept drawings ARE INSPIRING. Appreciate your finding-posting them. Sweep is similar to B-35/49. One of you model companies following this topic ?
Was comparing B-49 with built B-17. With careful cutting & PSR B-17 cockpit can be fitted. Used one on PBH-417 build. http://beyondthesprues.com/Forum/index.php?topic=2179.msg30402#msg30402 (http://beyondthesprues.com/Forum/index.php?topic=2179.msg30402#msg30402)
Thanks for your comments.
-
Back at it. Nose glued to wing. Right inboard engine glued. Others taped for picture. Fine tune filing (much as practical) engine to wing mounts. Each engine needs three axis alignment. Then PSR edges of nose and engine mounts.
Inboard prop has 27 inch clearance to nose. Can now see would work with four engines, going with six already prepared for mounting. Stabilizers not glued.
see attached pictures
-
Ooooo! I like ----- :-*
-
Oh yes what a fantastic flying wing, fins!
Looks wonderfully sleek and sharp.
I'd be tempted to call it the Arrowhead.
Brian da Basher
-
That looks amazing! Great work!
-
Looks like she's using Allison V-1710's. Are they going to be modified for high altitude or is she going to be low-altitude?
-
Yes. Those are P-40B engines-cowlings on this Curtiss one only experimental bomber built in 1940, first flying in Spring 1941. Good question and point; supercharger intakes in wing leading edge distanced from exhaust flow would be appropriate for high altitudes.
Became a ten kit bash. YB-49, Ki-67, 2x B-24, 6x P-40B
Now that I see what you see in pictures am encouraged to move along to timely completion. Appreciate the comments !
-
Are you going to give it a yellow (flying) wing scheme?
I'll get me coat.
;D ;D ;D
Brian da Basher
-
That Boeing model 306 (see above) is so beautiful! :-* :-*
-
And this Curtiss flying wing bomber is looking seriously good :smiley:
-
Yes.. very nice
-
Very nice kit bash. The B-24 fins really give it a late 30's early 40's feel.
-
impressive kit bash, and very elegant idea !
-

;D ;D ;D
Brian da Basher
Oh yeah. A paint scheme similar to this:
(https://imodeler.com/uploads/2013/04/015.jpg)
-
looking good
-
Thanks for gracious comments contributions. Being late prewar thinking color will be much like AAC 1938 spec rust brown (have the paint) with star & meatball insignia. Akin to attached B-17 picture but it is light olive drab. Late 30's early 40's feel as Frank3k said. Though am open to color suggestions.
Do intend to use yellow wing scheme on something early-mid 1930s. B-10 looks great. Seen that yellow with both blue and green fuselage.
Since am posting,,, here is increment of progress pictures.
Four engines attached. Some fussing to get them close enough eyeball aligned in all axis. God must have made Testors glue slow drying so you can make adjustments - very thoughtful.
Decided use OOB wing fences. Stabilizers to be removed and B-24 ones pushed forward to contact fence. Simulated that with stabilizers pushed forward alongside fences for photo.
Revell B-24D stabilizers have lot of sizable rivets. Will sand smooth to match wing.
-
This build just gets better and better with each update!
I like the way it's all coming together and the look of those engines as well as the fins (hehehehe) and rudders!
Brian da Basher
-
The asymmetrical look of your XFWB with three engines on one side and just one on the other would certainly have elicited an excited response from Tophe if he were to see this.
-
After number of oopses all six engines are on. Taking on big bomber look. With wingspan of 172 feet compared to B-29 of 141 feet needs six engines.
see attached
-
Wow that looks like a million bucks!
It couldn't have been easy getting all those engines aligned.
You're really pulling out all the stops on this fantastic build!
Brian da Basher
-
I am inspired by this project. Onward!
-
impressive indeed, a beautiful idea to have these 6 engines
-
Will go with a OD green over grey or NMF in keeping with the experimental idea?
This is such a “Wish I had thought of that!” project!
-
This is such a “Wish I had thought of that!” project!
Concour totally, now all the engines are on its looking awesome
Mog
>^-.-^<
-
Seems some of you have same interest in XFWB that I do - Thanks.
Now doing PSR on engine mounts. Finding Mr. White Putty works well.
Have cans of Krylon Brown Boots satin. Is like AAC 1938 spec rust brown (period correct). Considering it as top color with gray underside. Have time to change that.
-
... With wingspan of 172 feet compared to B-29 of 141 feet needs six engines.
And damned if they don't just look good! :smiley:
-
Thank you - six engines works for me as well. XFWB is progressing. Many iterations of PSR appear to be done. Primer white is on. Spots redone and now ready for underside gray. See how that goes.
Stabilizers painted "Brown Boots" satin. Starting props, thatz 18 tips to paint both sides - ulp.
-
Share some more pictures of the WIP, please! :)
-
Share some more pictures of the WIP, please! :)
Seconded! :smiley:
-
WIP pictures attached. Undecided what color(s) to paint top. Brown, Olive, Gray, Other in either one tone or two tone. Suggestions ?
After study of P-40 pictures decided for props -- red spinner, black blades, yellow tips
-
:icon_alabanza:
Great work
-
Beautiful!! Grey underside with two-tone, brown and light blue, camouflage on upper surfaces?
-
Here are two relative size pictures. Helps me to see unsure size models this way.
-
Can't go wrong with a classic olive drab upper (with medium green mottle and edge painting?) and neutral grey undersides.
-
Really great build you've got going Bill, makes me want to do one myself ---- :-* :-* :-*
-
That's going to be a stunner.
I'm almost sorry to suggest you go with a modified bare metal and yellow wings scheme for a pre-war look?
-
Beautiful!!
+1 8)
Grey underside with two-tone, brown and light blue, camouflage on upper surfaces?
Is that a historic scheme? If so, I can't remember seeing it anywhere, do you have a reference I can look up, Evan? ???
-
Not a historical scheme, just one I thought would look good. ;)
-
There was this P-47 scheme
-
A bare metal finish wouldn’t be bad, either...
-
That's quite an inter-continental experimental flying wing bomber you've got there!
I enjoyed seeing it next to the B-17.
Brian da Basher
-
You guys are great for chiming in regarding colors. Appreciated - Thanks.
Have another B-49 mostly assembled that found at swap meet. Did test paint with Krylon Italian Olive satin. Is perfect, will go with it. Now that colors picked can move along with build !
-
Your flying wing is looking soooo good.
Mog
>^-.-^<
-
Not a historical scheme, just one I thought would look good. ;)
:smiley:
-
I flexed a bit o' google-fu and I can see it!
The markings will looks fantastic against that Krylon Italian Olive.
Sounds like a solid choice!
Brian da Basher
-
Did paint top of wing Italian Olive. Looks so bombery to me. Two places paint demons raised hell. When dry will attack those.
-
Looks great! :-*
-
Back to building XFWB. After MUCH PSR & PSR "wing" is built and painted. Attached vertical stabilizers. Leaves clear parts, landing gear, props, guns, decals to do.
see attached
-
impressive !
-
:smiley:
-
Wow. In the underside view, the engines look almost liked podded jets.

Indeed. Gives me an idea for turboprops on something...
Splendid looking job!
-
Wow!!
-
*whistles* Beautiful!!

"Gob-Smacked" :icon_alabanza:
-
Oh, that is awesome!
-
Thanks all for your positive comments. First time to build one of AMT flying wing kits. By working on it can see various kit-bash concepts.
Similar builds could use C-130(H/J) engines or go turbojet/turbofan as 1950s-60s-70s.... versions. Instead of consuming six P-40B kits. Update stabilizers accordingly.
-
;D
-
Wow. In the underside view, the engines look almost liked podded jets.
Hail HYDRA.
-
Just read through this thread, simply inspirational work 8) 8) 8) 8)
Like the other members I can't wait to see the finished product :smiley: ;)
-
Following being flooded and bozo contractor from hell and fitting in build time on two 1/1 cars did more on Experimental Flying Wing Bomber. OOB main landing gear and parts bin nose gear. Rudder decals. Props taped on to get effect.
Progress pictures attached.

Coming along nicely! :smiley:

That is a beauty! I can just see the news article - "Newly discovered Boeing Flying wing from the late 30s!"
-
:smiley:
-
Nice to get more done. Final steps can progress faster than "involved" basic building. Interesting thought that it could be newly discovered locked in unused hanger since WW2. Am looking forward to finishing so you and I can see what XFWB really looked like. Will move on to Brian Perri memorial build after this.
Thanks for your interest and comments.
attached picture with 1/72 108 ft. gunboat and from rear.
-
That works. Nice job
-
After series of interruptions back at building. Was going to glue props in fixed position. Jeff recommended removable props to protect blades during storage/transport. Came up with three nested prop shafts per engine design resulting in removable and spinning props. Is more build steps but worth it. At least is easier than installing the engines. Hope to have more pictures in a bit.
Cheers
-
That is one beauty of a build. Inspirational, even.
-
Bill is now on Skype as a solution to the "social distancing" problem so I was able to view his WIP on my computer and that compelled me to make the suggestion for the propellers. Makes perfect sense to try and protect the fragile bits when transporting the model any great distance
-
Another winning suggestion from Fontaine Consulting Group, Ltd!
-
I have a bunch of those little soft-flexible bushings left over from several armor model kits and from spare parts acquired at past model shows and have often wanted to just toss the things out but could never go through with the action as I felt that at some point in the future they might be needed. Well the need never actually arrived but in past discussions with other modelers at the last model show I attended in Seattle the topic came up about broken propellers on models getting transported to and from the shows and the bright idea light bulb got brighter upon realizing I had a potential solution to the problem with those same soft-flexible bushings that I still had at home. The suggestion was well received but that was the last show attended since the social distancing so I have no idea if it was ever implemented by the modeler I had been conversing with. Hopefully Bill's solution will see the problem addressed with his own version.
When you think about it, the whole concept of a removable propeller held on by a flexible bushing of some kind makes perfect sense in that you can still have a propeller that turns but also a propeller that can be removed without breaking the thing for storage or transport to distant events.
-
Anyway back to the topic under discussion.
Bill managed to create a very impressive subject with this project.
-
Mods for removable-turning props are finished. Ki67 canopy with its opening panels bit of bugger. Using super fine sanding pads to clear glue smears. Will do differently on second try.
-
After mix of more interruptions and procrastinations am back at it. Estimate is 90% done. Been way toooo long.
Then bit of model room clutter reduction and do 46' GB.
-
Calling XFWB done. Though are last tidbits to do. Shine on decals is annoyance. You guys know what will dull them ?
So many parts not intended to fit together makes for lot of figuring and build difficulties.
Can now cleanup and start next build.
See attached pictures.
-
More pictures attached.
-
Well, she got there in the end! ;)
Great job, Bill! She looks perfect! :smiley: 8)
-
Oh, that is a stunner! Great concept and even better execution.
-
Shine on decals is annoyance. You guys know what will dull them ?
It's what happens when decals are put on flat/satin paint Bill. I used to not put my decals on my models just for that very reason. The solution is clear glossing the paint before placing the decals, then use a clear flat afterwards. The downside to that is when you clear gloss it, it will give the paint a 'wet' look, which doesn't revert back to the same flat look as before when you apply clear flat afterwards.
But I have to say that your model is very inspiring ---- wonderful build :smiley: :smiley: :smiley:
-
impressive !
-
That's gorgeous! The tail gunner looks great!
You don't have to gloss the whole plane - just the area where the decal goes. You can kill to birds with one stone by painting the decal area with Future and applying the decal before the Future dries. It will suck the decal into the surface (and into panel lines) you can the flat coat the area or the whole plane.
You can also see what Will Pattison does in this video (https://www.youtube.com/watch?v=cmMnYbNfYJA) - he applies a decal to 499 grit sandpaper. He also has several videos on decals (https://www.youtube.com/user/barpfoto/search?query=decal) that are worth watching.
-
That is epic! Excellent build (and the removable props are dead clever) :smiley:
The Hiryu nose is quite distinctive. With the B-26 (?) nose cap, the Ki-67 forward fuselage is totally unrecognizable! And very US-looking :smiley:
-
:smiley:
Any chance of an underneath photo?
-
Thanks so much for your encouraging comments :icon_alabanza: At this point don't recall where concept inspiration came from.
Been right for between the wars GB as Curtiss and Northrup experimental bomber project. First flight July 1940.
Looked at various kits for nose section. Ki67 was best fit with B-26 nose cap and B-24 canopy making it generic. Find that scouting for parts that work is half the fun.
Was hoping to find white 'U.S. ARMY' decal for top and use black one on bottom as done on B-10.
Underside needs landing gear doors finished and decals. Can send picture when that is done. Look forward to clearing table for next build.
-
that is so, so, so good.
Well done :icon_alabanza:
-
Wow.
-
Interesting thought that it could be newly discovered locked in unused hanger since WW2.
That would be one hell of a book shelf box display - spray down with adhesive, coat with 'dust'. Mount it on a circular base fixed to an old record player. LED lights as needed. Add some scratchy-head 72nd scale 21st century warehouse guys, tarp-covered stacks of boxes under the wings.

Variation on that theme -> https://www.youtube.com/watch?v=LBilqHbV_Wo (https://www.youtube.com/watch?v=LBilqHbV_Wo)
If my googlefu works, wingspan is just under 16"?
Clear lucite display boxes, made to order https://www.shoppopdisplays.com/CS001/5-sided-clear-acrylic-box-custom-size.html?v=19050&gclid=CjwKCAjwgviIBhBkEiwA10D2j-ja-EQDUC_euEgyWDjUaM3ZPmcHzjIgZrjFO78bOwAlg0WDbSW30hoCPjUQAvD_BwE (https://www.shoppopdisplays.com/CS001/5-sided-clear-acrylic-box-custom-size.html?v=19050&gclid=CjwKCAjwgviIBhBkEiwA10D2j-ja-EQDUC_euEgyWDjUaM3ZPmcHzjIgZrjFO78bOwAlg0WDbSW30hoCPjUQAvD_BwE)

Appreciate the interest and comments. Wingspan is 28.5 inches. Kinda large.
Found in old hanger diorama with convincing as possible backstory is interesting.
Took some in the sun pictures which show true colors.
-
Wingspan is 28.5 inches.
Oops. That's quite a difference.
It's like it needs it's own display stand. This is 29.5" for $50.

Could probably raise the black circular base easier than finding someone to bend ya three curved pieces of lexan for the sides.

Planning to take some models to Museum of Flight show this weekend. First show for XFWB.
Drafting attached as XFWB placard. Read good to you ?
Idea is to make it sound factual/plausible. Someone might try looking it up (probably not).
Those who know better enjoy the tongue in cheek write up.
While back showed C-47H with placard and saw one guy take it as the real deal.

Once again, for the record - this is a really neat build.
-
Thank you :icon_alabanza:
Must report today at Museum of Fight model show XFWB had a guy punching away on smart phone trying unsuccessfully to find history/documentation about it. I let him know it is kit-bash fiction.

Very nice , even the story bout the guy who started research … you should have a 20 year old mobile phone to give him instead of his modern touchscreen .
