Really glad to help.
2 really great projects I'm watching from the grandstands - the A-20 and B-26.

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.
One more a little more detailed.
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.lemonadedrinker

Hi,
[h=1]B26 Marauder | The Most Advanced Mid-Range Bomber[/h]
Weapon Documentaries
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.

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.
Steve
No problem Steve. I am using the earlier versions you posted; seems to match up closely with what I had and the numbers prove out. Thank you
You're quite welcome. Let me know if I can be of further assistance. As for the wing root and tip length, I don't really know, but the museum should be able to send you some blueprints that list those, since the ones they gave me for the Super Marauder did.No I am not; am still researching, but your post is heartening.

Looks Fantastic!!!
Thank you Sir; it is starting to take shape. We just need to get some R-2800's on this bad boy 'cause she is one pitiful glider.
Building these engines from scratch by necessity. It is painstakingly slow since there is no real 3-view help on these engines aside from general size .... Requires a lot of picture reference and do and redo. This represents 5 hours work but things are starting to look right on the cowling. Just getting started on this and much to do.

Just an update on cowling and intakes progress. I think I have it pretty close now. Chunked in some props at the appropriate size (13.5') to see if it could stand up to scrutiny.
Now on to the nacelles ...

I must've been asleep against a log cabin the woods. I swear I didn't see this thread. I love the Marauder. It is an aircraft they called a Widow Maker but proved itself over and over again in combat scenarios. It was tough and would bring it's crew home under some terrible situations. I think the early Marauder had some flight and landing issues that were addressed by lengthening the wings and reinforcing the landing gear. Thanks Milton...this is gonna be awesome.

Milton sorry I'm late to this post, but the b-26 is my favorite bomber and I am flying most of your planes. So I thought I'd try to be helpful. I have B-26 drawings from KOKU-FAN Magazine I could give you. There's 1 three view and 6 profiles. Don't know if I'm too late ,but they are available.
Thanks for the B-26.
