As intended, and after a lot of jostling of 3-views, the wing is under construction.

Great work as always Milton! Love your taste in aircraft (old radials) I know this will be another top notch much needed aircraft.
Milton, I was just wondering. Would there be any chance of including a version with the larger prop boss (as in the painting of a B-26 buzzing the Jap carrier)? Not sure if the painting is accurate, in terms of the boss, or even if that type of boss was ever used on production aircraft but it sure looks more streamlined and menacing to me. Of course, it could just be me. I never liked P-47s with skinny prop bosses. I always thought the bigger boss looked more aesthetic.
Here's hoping,
Taff
EDIT: Having just watched "WINGS: The B-26 Marauder" on YouTube it appears the larger prop boss/cover was certainly used on early variants.
The grass is always greener on the other side...
But, it's just as hard to mow!
Hi Taff, thanks for your interest in the B-26. The early B-26A's and initial B-26B-MA had the spinners. Beginning with the B-26B-1, a lot of improvements were made, and the large propeller spinners were permanently removed to improve engine cooling and reduce maintenance. See HERE.
If I do a short wing/tail version, it will include those spinners. Doing the early version, unfortunately, calls for significant changes in the fuselage, wings, tails, gear, some glass, gun arrangement and so really would be a different model along with a faster flight model. We'll have to see how things go before I commit to reworking it all, but I know there is significant interest in that model, me included.

I apologize for the bad link in the previous post; now corrected.
Maty, agreed, fast and careful attention to takeoff and landing speeds. Those early birds suffered from bad prop governors, distributors, and one other issue that eludes me at the moment, plus inexperienced pilots and maintenance crews. The experienced guys in the Pacific loved these early Marauders and thought they got a bad rap ... which they did. The AAF also ruined the model's performance with its changing role and added weight over its original design philosophy. Much the same happened to the Vultee XP-54 in its changed role topped by engine requirements that were not met by two different manufacturers.
Well, lost all wing progress today due to my inattention to details. :-)
Started out on the wings, got one about half done with ailerons and trim tab finished when I realized some errors on the 3-views, all of them regarding flaps.
The Marauder has split, slotted flaps inboard and outboard of the nacelles on the long wing variants.
All my 3-views show slotted flaps but not split flaps.
This was on top of some 3-views showing a conventional airfoil versus the symmetrical NACA 0017. Invested a lot of time trying to find the NACA 0017-64 and it was no where to be found. So I improvised creating the bottom curve to match the top curve. Went to measure my vertical distances at the root and tip and they were off across the whole wing.
Was not happy with all of that so I scrapped the wing to start over. Still trying to find the airfoil drawing before I restart. Anybody have access to the NACA 0017 and 0010, I would appreciate the help. LOL Such is life; I knew this morning that today wasn't a good modeling day; nothing seemed to go right. :-)

Milton, are you sure about the split flaps? From everything I've seen, the short wing Marauders had the split slotted flaps while the long winged seemed to have Martin's own take on Fowler Flaps, rather similar in design to the Mariner, with double hinges on each arm to push it aft and rotate it:
P.S. Forgot I had this flight manual as well, for the long wing version:
http://1.airwar.z8.ru/transfer/manual/[aviation]%20-%20[manuals]%20-%20B-26%20Pilot%20Training%20Manual.pdf
Lists incidence of the airfoils, control surface limits and has some nice illustrations
No I am not; am still researching, but your post is heartening. :-) Gives me more confidence that the 3-views have validity.
Okay, just now found 4 different reference pics and one cutaway that validate your statement. Thanks for that refreshing morning slap in the face. :-) I am awake again.
Also had a copy of that training pdf from another source. Thank you so much. With that resolved and the air foil (thank you Duckie), I can proceed.
That looks nice as well Steve.
I am trying to reconcile the height differences from the previously posted pics.
The 0017 is 17% thickness compared to the chord length. This one looks "fat". :-) Although, when you count the grid squares, and divide by the height squares, it seems to work out.

Not sure quite how to let you know about this interesting 50 minute documentary. This is on Yuo Tube. The first part is about it's development, and if you haven't seen it (which I doubt!) there might be bits that interest some here !
This aircraft will be stupendous, and all power to your elbow, Milton; no more early morning slaps, though !

LOL Andy, I have seen that video but your link points to the B-52.
Here is the correct link posted by Bjoern above.

Anyone have wing info on root and tip chord length for the B-C models? I cannot find that anywhere.
From the drawings, the root appears to be 158" and 27" high at apex which comes in at 17% but not sure how close that is. I have nothing on the tip length.
Milton, I can't vouch for the sources. They were pretty well buried in the WWW but, according to the site and doc titles, they are from aeronautical engineering houses and are abstracts submitted for current (at the time they were submitted) projects. As far as I could tell, one was for a hydro foil design, and the other was for an aft fuselage stub wing mount for some kind of turbo-fan powered business jet.
Like Sgt. Schultz, "I know KNOOOW NUHTHINK!" I was just searching for "NACA 0017 airfoil" and turned these up hoping they might be helpful.

Okay, once I got my act together (thanks to all of you), it took only a few hours to knock out the wings.
Now on to the engines.
Some cleanup here on the gun pods and wing fit to the fuselage now done.
Looks Fantastic!!!
