If you really want to dive into scale details, I have yet to see a model F-16 with this antenna.

Your F-16 isn't a model. You figured out a way to miniaturize a real one.

John,

The larger wing on the Viper was with the A/B model blocks 5, 10, 15, and 20's. It was 21.5 inches longer than all C/D block 25, 30/32's, CG/DG block 40/42's, CJ/DJ block 50/52's. That wing was 31.0 feet for a wing span.
Do you have a reference for that info? Working at LM Fort Worth with folks that worked early and late model F-16 Flight Test, I asked and cannot find anyone that knows anything about a larger wing (apart from the XL). The big tail & big inlet mods are well known, but nothing on a 'big wing'. The 'beer can' or 'Donkies D*ck' RWR antenna was one visible wing mod, starting at Block 30D


From F-16.net

Externally, the F-16C is almost identical to the F-16A. The only significant external difference is the introduction on the F-16C of an enlarged triangular base or "island" on the rear fuselage leading up to the vertical fin, with a small blade antenna protruding upward from it.

Now, if you were modeling a scale Block 40/42 jet, you could measure the landing gear length
The undercarriage legs were made longer in order to provide more adequate clearance for the two underfuselage LANTIRN pods, and were beefed up to handle the increased weight. The aircraft also has bulged landing gear doors to accommodate the larger wheels and tires, and the landing lights were moved to the nose gear doors.

On further internet research, I think the difference in reported span of the F-16 is due to measuring the span with or without the wingtip missiles.

Whilst none of the list below is a formal declaration of information (from the web, so must be true), and there are slight variations in the numbers, I think the consensus is there;

Wingspan for all F-16 variants from initial A model onwards (excluding XL) was;

Without tip missiles: 31'0"
With tip missiles: 32'8" - 32'9.5" (missile type not specified)

The basic wing size appears to be constant across all variants.

F-16.net

F-16A/B Dimensions: wingspan 32 feet 9 1/2 inches, length 49 feet 3 1/2 inches, height 16 feet 8 1/2 inches, wing area 300 square feet.
F-16C/D Block 25 Dimensions: wingspan 31 feet 0 inches, length 49 feet 4 inches, height 16 feet 8 1/2 inches, wing area 300 square feet.
F-16C/D Block 30/32 Dimensions: wingspan 31 feet 0 inches, length 49 feet 4 inches, height 16 feet 8 1/2 inches, wing area 300 square feet.
F-16C/D Block 40/42 Dimensions: wingspan 31 feet 0 inches, length 49 feet 4 inches, height 16 feet 8 1/2 inches, wing area 300 square feet.
F-16C/D Block 50/52 Dimensions: wingspan 31 feet 0 inches, length 49 feet 4 inches, height 16 feet 8 1/2 inches, wing area 300 square feet.

Af.mil
Wingspan: 32 feet, 8 inches (9.8 meters)
Length: 49 feet, 5 inches (14.8 meters)
Height: 16 feet (4.8 meters)

sky-flash.com

F-16 A: Wing span: 10,01 m.(over missiles)

http://www.iaf.org.il/645-en/IAF.aspx

Wingspan - 9.45 meters, With missiles - 10 meters.
Length - 14.93 meters.
Height - 5.10 meters

Good point about contacting SM regarding the F16 reference they used.
David what do you make your scale parts out of? I know 3D printing seems popular but can get heavy. Could you share some detail pics of your F16?
Thanks

​​​​​​Levi you can get good results with 3D Printing as long as you can get good models for 3D Printing (i.e. hollow vs solid). They come out rough, but you can prime and sand and get good results. At the scale you want, weight is not an issue for small parts such as pitos, antenna, scoops. The only difficult part to make would be a thin fin base for A models if that's what you have.

Which bird exactly do you want to make?

Also, I think the different wing profiles may be due to a manufacturer error. I know that SM and FEJ wings on their small F-16s are sport scale to give them better performance, perhaps they carried the error to some of the large scale molds?

In any case, use Peter's as a reference 😁
id bet he's is more accurate than Lockheed's.

Umm,, I don't think you can get any more exact accurate information than what this man just shared.

As I stated I copied from F-16.net. I never had any idea they were different. I wondered later on after talking with Dave Evans if it wasn't just that they measured with Missiles on the A/B model. From what I have seen over the years the only real accurate F-16 came out of the Netherlands many years ago.It was a Block 25 I believe, or possibly 32. Cannot remember it has been so long. I remember the first 42's I worked and after an accident on landing of a bird strike having to replace a left main gear door, rigging that stinking little follow up door was a pain in the ass!! Still the greatest jet ever. Also would have been nice if they could have got the ECM package to work in the vertical! I hated ECM pods! lol

Not an expert myself. The drawing file name suggests block_30 but that is all I know.
Does the pic mean anything to anyone? Note the date.

The green line next to shoe is of course not the hinge line but the panel line. The LEF hinge-line is forward of that, albeit rather faint since the fit is so good.

Thanks for that Peter. Your info matches in with the diagram in the previous post that measured the opposite angle at 39.9deg, forming the total angle at 90deg.

Some good posts and info in this thread. Thanks to all my question has been answered.
