  1. Which was a problem, because after an hour in hot weather, it smelled like a goat…
  2. Strictly speaking, they weren’t “silver” but were mostly natural metal or painted overall with aluminized lacquer when it became clear that corrosion control on carrier-based natural-metal airplanes was ineffective. Also see https://thanlont.blogspot.com/2009/12/it-seemed-like-good-idea-at-time-vii.html
  3. The split flaps would begin to slowly droop after engine shutdown.
  4. The A4D/A-4 horizontal stabilizer was movable for pitch trim. Nose-up trim (stabilizer leading edge down) was desired at approach speeds. The pilot generally left the stabilizer that way after landing: if I remember correctly, that was desired for post and/or preflight visual access to the stabilizer control mechanism. However, that was too much trim for takeoff and it’s not unusual to see the stabilizer positioned horizontally. Repositioning it also closed the very noticeable gap in the fin underneath the stabilizer to preclude birds from setting up house inside. The gap, by the way, resulted from the addition of the sugar scoop over the aft end of the fuselage above the tailpipe opening. Since the stabilizer is one piece, there is a large opening in the fin to allow its motion for trim. A sheet metal fairing attached to the upper and lower sides of the stabilizer closed the gap, the same as on the AD Skyraider and the A3D Skywarrior. However, when the sugar scoop was added, the bottom of the lower fairing had to be trimmed to clear it and therefore no longer covered the gap through the full range of stabilizer nose-up trim.

  6. I just received the 1/72 kit from Hannants; it's now out of stock but can be back ordered. I was a bit dubious because some 3D pieces I’ve seen are pretty crude, with what looks like “layer” lines. Others are fantastic: one-piece afterburner nozzles that couldn’t be matched with multi-piece injection-molded parts. Even though it was expensive, I took a flyer on the kit because the Blackburn Blackburn that I have in my stash is a Contrails vacuform. How bad could it be? The answer is that it’s a work of art even unbuilt and has assembly features that are modeler-friendly, like multiple pegs to attach the wings and the upper and lower wings on each side are a single unit, connected by the interplane struts. Fantastic cockpit detail, appropriate raised and engraved features: It’s truly stunning. My pictures here of a fuselage half and one set of wings: https://www.tapatalk.com/groups/72nd_aircraft/blackburn-blackburn-t12165.html#p118108
  7. A bit of F4H history - there was no slanted bulkhead in the aft cockpit on which the ejection seat rails were mounted. The aft bulkhead in the aft cockpit was vertical, a vestige from the conversion of the single-seat AH to the two-seat F4H. The compartment behind the pilot (it originally contained the ammo for the cannons that were deleted and some other odds and ends of utility and other systems) was repurposed to cram in a second seat for a radar operator. The ejection seat rails were separate from the bulkhead, slanted like a ladder leaning against a wall. Not worth correcting, of course, particularly in 1/72nd.

  9. I can confirm 72Modeler's observation based on a response from an EA-6B crew member to my specific inquiry. The rear seats are not staggered. The reason that the front seats are staggered in all A-6s was to provide the pilot on the left with a bit more cross-cockpit visibility for see-and-avoid purposes in VFR weather since the bombardier might be otherwise occupied. As to longitudinal positioning of the pilot with respect to the controls and visibility, I'm pretty sure that at least the seat bucket would go up and down and the rudder pedals would move back and forth.
  10. Trivia: Rear cockpit controls were evaluated by the Navy very early on in the F4H program. It basically consisted of the flight controls and an extra instrument or two, that enabled the airplane to be flown from the back but without some critical capability, like brakes if I remember correctly (it's in my F4H-1/F4H-1F/F-4A monograph but I'm away from home). The Navy decided dual controls weren't required (it was considered an easy airplane to fly and there weren't enough instruments in the back seat for instrument proficiency or visibility from the back seat for a safety pilot) but the provisions for them and drawings were used by the Air Force for its F-4s. XT-595 and 6 had throttles in the aft cockpit but no stick or pedals, basically so a pilot or flight test engineer could independently operate the Speys as required for inflight testing.
  11. The front seats of the EA-6B are offset but the rear seats are not.

  13. My in-box review of the kit: http://tailspintopics.blogspot.com/2021/08/lf-models-piasecki-hrp-1.html If anyone builds it before I do (which is almost certain), I’d appreciate a picture of the model and build notes that I can add to this post.
  14. Most of the links in this topic are broken but I did my best with what I found elsewhere: http://tailhooktopics.blogspot.com/2021/08/north-american-ra-5c-flasher-pod.html Additions and corrections are welcome.
  15. A corner reflector provides a much better return than the door, necessary for the position accuracy of the approach guidance: https://en.m.wikipedia.org/wiki/Corner_reflector
  16. For me, the caption on that picture of the ejection seat calls into question the author’s depth of F9F knowledge. That’s a very early Grumman design that almost certainly wasn’t in even the first production F9Fs. See https://tailspintopics.blogspot.com/2016/03/early-us-navy-ejection-seat.html
  17. F3H-2s were initially delivered with the McDonnell seat. Also see https://tailspintopics.blogspot.com/2010/11/f3h-demon.html
  18. No problem; that’s what they are for, no watermarks, etc.
  19. For the rest of the story, go here and scroll down to the bottom: https://tailspintopics.blogspot.com/2018/06/ad-4w-skyraider.html
  20. You see those straight-sided rectangular recesses slanting back from the top of the bulkhead with the large lightening holes in it? The right one appears to have a cup holder to the right of it. Those are where the seat pack parachutes go that the guys in back sit on.
  21. Thanks for the excellent build information. Some more on the airplane and kit here: https://tailspintopics.blogspot.com/2019/08/sword-172-douglas-ad-4w-skyraider.html
  22. Thanks - also see https://tailspintopics.blogspot.com/2011/10/yankee-tractor-rocket-escape-system.html

  24. I made up “snaggers’ too because I was too lazy to look up what they were actually called. The key points are that they did not have an aerodynamic purpose and were only there for a barricade engagement, not one involving the Davis barriers.
