The R-1535 series had a diameter of just over 44 inches, the diameter of the R-2800 series varied from
52 inches up to 53 inches.
Installed length of the R-1535 series varied from 53.25 inches up to 55 inches. Installed length of
the R-2800 series varied from around 75 inches up to over 100, depending on supercharger set up, etc.

So a diameter increase of 8 to 9 inches and a length increase of at least 22 inches.

From an appearance standpoint, the F7F would probably be the best basis for how to cowl the R-2800 on a developed Model 24.

For a different approach, how about F-80 or T-33 style tip tanks?  For that matter, I still think the stretched center nacelle of the "Lightning Swordfish" testbed would look good  with a radar nose and the canopy from the T-33.

"Lightning Swordfish" testbed

What's that Evan ?  I can't find anything about it ---  and it sounds very interesting

Like this?


The downside of this one is the lack of visibility the turboprops cause. I should have moved the cockpit forwards and up. Oh well.

Well, actually the laminar-flow test was a cab-on over the basic P-38 wing.  The ""Swordfish" started out as a P-38 with a stretched center nacelle.  I understand that the improved fineness ratio actually helped performance a bit.

The stretch I was thinking of involved the crew nacelle, not the engines, but the relocated cockpit of the "Swordfish" would help with visibility in this case.  Of course, for really good visibility, you could put the pilot where the student pilot sat in the trainers the Italians converted; the student sat right above the nose landing gear trunnion and I'm sure this encouraged smooth landings.

Now that's motivation!  ;)
Something that was nice when I was scratching this beast up was that the T-33 fuselage pretty much dropped right onto the P-38 pod without much effort. Seems the basic shape was pretty close. Coming from the same company, I shouldn't have been surprised, but I was.
Stretching the pod should then be faily easy, merely use a donor T-33! :)

*shrug* SO, what do  you do?  Me, I'm going after a F-94C to do a cross with.  The early-model ones without the mid-span rocket pods are cheaper, though I might also grab a Heller F-94B for the mid-span gun pods.

I'll just build it anyway and get a Sword kit or two as well, anyway.

I know the feeling, I had hunted for ages to find a Griffin vacuform kit of it and found one a year or so ago.  It might get used instead and I'll just build the Sword one OOB.

EDIT:  at Hannants right now and just ordered one.  I had the item in my 'Watch' list and an email arrived this morning saying it was on the shelf now, along with the Harrier T.2 and T.4 which I also ordered ----  ;)

Well, it took 20 years to complete the Turbo/Super Lightning. Now I'll have to start over again, this time using the SeaStar as the cockpit section. I'll let y'all know in 2033 if I ever got it done! :o

Random Idea:  P-38 with prone pilot.  In other words, take a droop snoot P-38 (see below) and remove the standard cockpit altogether.  Maybe give the now prone pilot a periscopic sight (ala the Ar234) to see behind.  Maybe say this is a high speed recon version.

Quick question - how different externally are the P-38J and P-38L (in terms of what would be noticeable in 1/72)?

I don't think there was much externally different between the pair...at leat visual and especially in 1/72 scale.  Others may know more here though.

About the only thing I can think of is that the "L" was the first to use zero-length rocket launchers...though that is only an issue if you fit such.

The biggies for the 'L compared with the 'J were:

- Port wing leading edge landing light (retractable underwing light on 'Js).

- Mid-chord dive recovery flaps

- Underwing fuel pump fairing (for revised fuel tankage).

Two R-1535 Twin Wasp Jr.
Span: 54 ft
Length: 34 ft 6 in


I was thinking about this version and I was wondering how well it would have handled itself during shipboard landings?  The tail hook would had to have gone at the end of the fuselage, IE about the middle of the plane.  That alone makes me think it would have issues.

http://www.aircraftresourcecenter.com/rh/articles.php?id=6580
The builder of this one indicates it would have had serious arrested landing issues as well but I have no idea whether his conclusions are based at all on facts or just fiction.

Thoughts?

Would the slightly upturned tail booms on the proposed float plane version have helped at all maybe?  Seems like it would need an awfully long hook and have to come in at a relatively shallow angle VS other carrier aircraft; problems???

Regarding the carrier Lightning.
How about extending the rear of the cockpit nacelle, say 5-6ft or so, or in line with the radiator ducts, allowing either an extended hook, so, the angle between hook & deck is lessened along with any stresses, or shift the hook further back so the hinge line is behind the cockpit & attached to the bulkhead & covered by a fairing?

Does that help?
