As far as I know (I was a flight test engineer on the F-4K/M program and only arrived at McDonnell in time for the first flight of the F-4K) BAC was simply a subcontractor for the aft fuselage and had little if anything to do with its design and the integration of the Spey into the fuselage. My understanding is that the Brits wanted their Phantom to have 50% UK content. Since the airframe, engine, and avionics were each about 33% of the production cost, that was accomplished by BAC providing the aft fuselage, Rolls Royce the engines, and some odds and ends of substituted avionics (I've read that Ferranti was to produce the radar under license to Westinghouse but I don't know if that actually happened). The transition of the F3H Demon to the AH-1 to the F4H-1 is an oversimplification but there's an excellent monograph available on that if I do say so myself (to say more might get me banned again by an overzealous admin).

I have provided information on request to several kit makers. Only one ever asked me to review the test shots: they never asked again for even information (none have asked me to look at the kit instructions except for markings illustrations; a few times I got a chance to look at the initial drawings before creation of the master model/tool).

Strictly speaking, the Sparrow came first. The F4H Phantom was the still-borne, single-seat AH modified to accommodate four of them along with a 600-gallon bespoke center-line tank to meet the time-on-station requirement:

There's a pretty good drawing of the underside of the wing showing the flaps here: https://tailspintopics.blogspot.com/2021/06/mcdonnell-f2h-banshee-stores-pylons.html -

There shouldn't be a gap between the engine fairing and the tail pipe (also note the flaps): -

Yes - it's an AJ. -
A Sabre Dead-End: the F-86C/YF-93A
Tailspin Turtle replied to Sabrejet's topic in Work in Progress - Aircraft
The best inlet for pressure recovery at the inlet itself is one in the nose but that requires that the duct go around the cockpit and there are losses associated with a long duct. Simple side inlets increase the frontal area (drag) and ingest low energy boundary layer air that reduces pressure recovery. The NACA "flush" inlet was very clever in that the shape generates vortices that cause the boundary layer to spill out over the edge of the inlet. Nevertheless, as the F-93 proved, overall it was not as effective as an air intake for jet engines as a side inlet with boundary layer removal. It is, however, a go-to inlet for smaller volumes of air intake requirements and really looks racy. It was successful, or at least adequate to the task, on one airplane application, the air intake for the jet engine in the aft fuselage of the AJ Savage. One of its benefits in this instance was that it could easily be closed when the jet engine was not needed. -
Thanks - I have now found that page. Direct link provides the same URL that I stumbled on by opening the image in a new tab.

Thanks - I haven't seen that page. It makes sense.

test: If I remember correctly, on Imgur itself, I opened the image "in a new tab", copied the link on that, used it in "Insert" button, and here it is. This is the URL that was copied from the Imgur web site: https://imgur.com/9hzKsLR The difference was that in the new tab, "imgur" became "i.imgur" and ".jpg" was added to the end of the URL copied from the Imgur web site.

https://imgur.com/9hzKsLR I'm pretty sure that I did what you said, but it doesn't make a difference in the appearance when posted.

I've gotten the URL from Imgur (it's my model and the image uploaded is from my computer) but it turns pink when I try to add it to a post using "Insert image from URL". https://imgur.com/a/c3QsoDm

I thought that the deep panel lines would be off putting but they aren't when the model is surrounded by others on the shelf.- 33 replies

I've done some photo research looking for pictures of the A4D/A-4 speed brake well. As Steve notes, actually finding one with the speed brake even cracked (except when in the process of landing on a carrier) is rare. However, the surprising result in the ones I did find of that era (but not that particular cruise, much less airplane) was that the well was definitely light gull grey, not white, although the actuator body was white and the inside of the speed brake itself was red. It didn't seem to be quite the same color grey, maybe a little reddish (hydraulic fluid?).

I taught aerobatics once upon a time and had an airshow waiver for altitude. The entry speed looked adequate and so did the pull-up. The roll looked OK initially, maybe a little slow and not quite as nose up when inverted as I'd want, until just past inverted, when the roll rate seemed to slow excessively and the nose dropped precipitously. He reportedly performed the same maneuver the day before with no drama. Others suspect a control restriction resulting from an object in the cockpit being displaced when inverted.

A-1E, A-1H centerline backwards facing hook
Tailspin Turtle replied to 72modeler's topic in Aircraft Cold War
There's a picture of the torpedo nose cap here, not to be confused with the plywood barrel that stayed on the torpedo until it hit the water. https://tailspintopics.blogspot.com/2010/01/us-navy-aerial-torpedoes-in-world-war.html One of the functions of the barrel was drag so the torpedo didn't gain too much speed before it hit the water. The function of the cap was to reduce the drag of the torpedo until it was dropped. -
Royal Navy Corsair with added new Questions.

There may not be any USN aircraft cards marked F4U-4C, but for sure there was a Corsair, at least briefly, marked F4U-4C: https://thanlont.blogspot.com/2014/03/navy-aircraft-designation-suffixes-redux.html- 57 replies

P-51 red L-shaped flap stencil - one or both sides?
Tailspin Turtle replied to Phantome's topic in Aircraft WWII
Maybe. My guess was that it allowed the Navy equivalent of a crew chief to warm a piston engine up and then exit from one side while the pilot had climbed up on the other (note, however, that later Corsairs only had boarding provisions from the right side). But it took a while to standardize on the left-side, possibly influenced by those who rode horses. See https://thanlont.blogspot.com/2015/10/carrier-based-airplane-self-boarding.html -

That is the Douglas-developed low drag tank that was introduced after the Korean War. Also see http://tailspintopics.blogspot.com/2016/09/things-under-wings-post-war-external.html
