82Whitey51 Posted March 2, 2017 Share Posted March 2, 2017 Here's a few interesting photos of A-4s Note the angle of the tank fins...and the lack of tank fins. Not something we typically see, especially on models; Photos from this web site...jammed full of great reference shots; http://www.agc-art.com/idobata/joyful.cgi?pg=0 Quote Link to post Share on other sites
Rex Posted March 3, 2017 Share Posted March 3, 2017 (edited) The fins attached in only certain places on the tanks. The empty slots you sometimes see are the unused fin attachment points. There were Eight fin attachment points per tank. It appears that this was done with the sway braces, tightening them to be canted out slightly, maybe something to do with that Walleye? As for no fins, that was also used a lot, and there was also a variation with two fins angled up (or was it down?). (that last one is much rarer to see, though) Just general info,,,,using the tank to get up on the wing was okay,,,,,,,,using the fins was very much NOT okay, lol. PS, note that camera on the front of the centerline pylon on AK-210. Edited March 3, 2017 by Rex Quote Link to post Share on other sites
Rex Posted March 3, 2017 Share Posted March 3, 2017 dang, did it again that should be "eight tail to tank attachments", with Four fin attachment slots. Quote Link to post Share on other sites

Right, so the "tail cone" section of the tank can be rotated around to configure the fin angles I'm thinking? But the lugs are in one place only? Like the S-3 configuration typically is in an "X" pattern, were as the A-6/EA-6B has a single fin on the lower side straight down so I imagine the fin attach point are at four points opposite each other. I'm still trying to find info on if it's the Walleye that dictates the fin angle on the A-4 above. Quote Link to post Share on other sites

Maybe these are the 400 Gallon tanks? They basically look the same but are (of course) more bulky and therefore had to be canted outward because of the main landing gear doors?

Rex Posted March 3, 2017 Share Posted March 3, 2017 I looked around at some of the photos in the books. It seems that the cant was done even on A-4Bs that had nothing on the centerline. So, my thought that it had to do with the Walleye doesn't apply. Most of the time the fins were straight across, though. The last time I mentioned the 400 gallon tanks on the wings, it was pointed out to me that they were only used on the centerline on Skyhawks. (Ginter's drawing was in error) I thought I remembered A-4M "Supertanker", sort of like the late KA-6D, but I guess I was wrong about that. And you have it spot on, Whitey,,,,,,,,,four places to attach fins, but, the pylon lugs are in a fixed position. So, the tail cone is rotatable, to allow changing for different aircraft types, or different tail cones. (smooth tails with no points and no fins were more common in pics than the canted mounting with two fins) I'm glad you posted that pic, Whitey,,,,,,,,it gives another variation for a Scooter model. (and I need as many variations as I can find) A modeler better make sure to have a pic with an entry form, though,,,,,,,,I am sure that will be seen as "model part mis-alignment" at a show.

Best regards, Jens Hmmm...speaking of MLG doors...where are they? Look at the photo again. Shouldn't they be in view, butted up against the tank?? I see the doors for the struts...but I don't see MLG doors. Edited March 3, 2017 by 82Whitey51 Quote Link to post Share on other sites
Finn Posted March 3, 2017 Share Posted March 3, 2017 This one looks to have a 400gal tank on the c/l: for the wing tank fins, i think the pylons are slightly canted out, therefore the fins at the back would be slightly angled. Of course other pics do show them level or otherwise so the adjustments of the crutch pad swaybraces would effect the angle. Jari Quote Link to post Share on other sites
Rex Posted March 3, 2017 Share Posted March 3, 2017 yeah, Whitey, good eye. They should be out there almost banging on the tanks. It is strange enough seeing a Willy Lover carrying a Walleye. That pic has all kinds of cool things going on, eh? Quote Link to post Share on other sites
Finn Posted March 3, 2017 Share Posted March 3, 2017 The doors are there, just look closer and you can see them. Speaking of Walleyes, here is another Marine A-4 with one out on a combat mission: http://a4skyhawk.us/content/buno-150121-vma-223-wp-24 probablyy a Mk-83 on the other side for balance.

Rex Posted March 3, 2017 Share Posted March 3, 2017 It could also be a pair of Walleyes, like the VA-212 photos. They were carried both ways, and also on the centerline with fuel tanks. Regarding the doors, he means in the WL photo,,,,,,I can see the backdrop is unbroken between the tank and the small doors. But I don't see the large door. In your photo, yes, we see the tree outlined by the door shape. And after squinting longer at the WL photo,,,,,,those sure look like "fat tanks", unless there is some shape distortion going on caused by photo angle. Quote Link to post Share on other sites
Finn Posted March 3, 2017 Share Posted March 3, 2017 In the WL pic if you look between the left tank and the main gear strut you can see the back of the door edge, on the right side there should be daylight between the tank and the pylon, aside from the plumbing from the tank to the a/c.

Rex Posted March 3, 2017 Share Posted March 3, 2017 yep, I see it now,,,,,,,,you're right. Thanks for pointing it out,,,,,,,,but, once seen, that rear door edge is impossible to miss when you scroll down and back up. (hah, funny what you can see when it is pointed out, eh?)

Oh yeah...and you can see it's reflection in the port side tank too. Quote Link to post Share on other sites
