X-35A JSF - In-Progress

Back in 2007, I built the Panda F-35 JSF kit. At that time, it was the only 1/48 scale kit of any F-35. I jumped in and had a great time building it. It was so good that I took 3rd Place in the 1/48 Single Engine Jet category at the San Antonio contest back in February 2010. (I was pretty proud of myself, considering I wasn’t going to take it.)

At the time the production aircraft starting rolling off the assembly line and I painted it like the first F-35A - AA-01 (with some artistic license). I knew the Panda kit was closer to a prototype than it was to the production aircraft.

Fast forward seven years…I picked up the X-35B USAF boxing of this kit (which should say X-35A USAF). I thought now would be a good time to build this kit as the demonstrator. I remember the kit being very well fitting and easy to put together. This seems to be no different.

I started doing research and pulling all the pictures I could find online of the demonstrator aircraft. Remember that “simple build” remark above…well, not so much. I don’t know where Panda got their information to produce this kit. While this kit looks like the early JSF, there’s a lot wrong. (BTW, the 1/72 Italeri X-35 kit is just as wrong as this one - it makes sense, since Panda scaled up the Italeri kit)

The kit is the X-35B with the Lift Fan doors, except with a straight engine nozzle. The “USMC” boxing does come with the 90 degree nozzle and the STOVL decal sheet.

After researching the aircraft and studying the kit here’s what I have found…
*The entire bottom of the fuselage is wrong. The X-35 aircraft, X-35A/B and X-35C, have a smooth belly. This kit is pure conjecture. It possibly resembles the full scale mock-up.
*The vertical stabs are set too far inboard.
*The cockpit is purely fictional. The ejection seat isn’t representative of the aircraft seat.
*The intakes are squared off at the bottom. They should have an angle going aft. (Look at the intakes on my earlier build above, they are unmodified)
*The exhaust nozzle is wrong. It should have smooth “turkey feathers”.
*The gear doors are completely wrong for the demonstrator. They possibly copied the mock-up here.
*The nose landing gear should be an F-15 nose strut and wheel.
*The aft engine section should be straight where the exhaust nozzle is sticking out. None of the angles should be there. Once again, I suspect they referenced the mock-up.
*No air data probe for the nose radome.
*Various antennas, vents, inlets and exhausts are missing.

There’s more…but I stop here. Most if this is easily corrected. The struggle is the aircraft belly. I think I am going to leave it as is. It would take a lot of Milliput to correct it, not to mention getting the contours right. Some things, I think are okay just as they are. Besides, once it’s done, there will be no denying what it is whether I fix the belly or not.

In-progress pics…
Cockpit - I painted the cockpit and main instrument panel neutral gray. I picked out the details with flat black and flat red. Since this model will be in-flight, most will be hidden anyway due to the pilot figure. The ejection seat was cannibalized from the Tamiya 1/48 A-10 kit since it’s incorrect for that kit. The pilot is a mix of Hasegawa pilot parts. The center pedestal of the MIP had to be narrowed to allow the pilot to fit.


Bottom
The intakes should be modified and angled aft.

Top
Some of the panel lines are wrong. Fill those in and re-scribe new ones. Also, various stiffener plates are missing as well. Vertical stabs were moved 2mm outboard.

Overall
The air data probe was cannibalized from the 1/48 Academy F-111E kit and modified to match the aircraft.

Exhaust
The exhaust nozzle should be smooth all the way around and not have the angles that are represented in the kit. These were filled in multiple times until smooth.

Canopy and Cockpit
At the upper aft center line of the cockpit there is a tab sticking out and a notch cut into the frame. These shouldn’t be here. The tab was removed by sanding it smooth. The canopy notch was filled in by gluing in a piece of styrene and sanded to match the contour of the frame. The canopy frame on the centerline, upper aft, needs to be corrected as it follows the contours of the notch. It was sanded to follow a straight canopy railing per the actual aircraft.

Reworked some of the panel lines…since all of them are wrong. I did begin to re-scribe, but I wasn’t happy with the results so I filled everything I did and sanded it smooth. I like this look much better.

The actual aircraft has various intake scoops and exhausts. Minus the main engine exhaust nozzle, ALL of them are missing.

Here is the actual aircraft:

I really don’t know what that forward intake actually does, but it’s gotta be there.

Here’s my solution:

I used Evergreen square tubing cut down and thinned. The separator is was glued with CA and sanded to match.
(Sorry for the blurry pic)

Placed on the model:

Cockpit Aft Section

Actual aircraft

Scratchbuilt aft canopy support

Aft Fuselage - Engine section - Actual aircraft
Doubler strip

Model
Added doubler strip

Left Side
Added Exhaust vents

Right Side
APU Exhaust deflector

Looking pretty danged good so far. Keep it comin"!

I really like the mods!

Not an attractive aircraft at all… Very nice work on the mods! I think filling the panel lines is wise, as in reality those would detract from the actual aircraft’s stealth abilities. I wonder if the 1/48 Italri kit needs all these mods as well? Can you post a link to where you are finding all this info?

@stikpusher

I didn’t know Italeri had a 1/48 scale kit of the X-35. I had the 1/72 scale kit, and it’s just as wrong as this one and needs all the same mods.

As far as references, Google is my best friend. the jsf.mil website also has some really nice high resolution photos of both demonstrators, X-35A/B and the X-35C. I did find a couple of Flickr albums where folks have taken phots of the X-35A/B at the NASM, those were very helpful.

Thanks for that info Steve. I have been looking at the JSF website just a few moments ago. Photos on there tend to be more of the B & C variants from my quick look thru there. Or at least on f35.com. I will take a look at that jsf.mil site later on here. Yes Italeri has a 1/48 kit of this bird. I dont know for certain, but offhand I suspect that it is a scaled up version of their 1/72 kit. I picked up mine in 2005, so I bet that it is lacking many new details.

Oops, scratch that 1/48 JSF being Italeri, it’s Revell Germany. I just pulled mine out of my stash to take a look.

The Revell kit is the Panda molds. Although, the Revell kit has the weapons bays. The Panda “F-35 NATO Fighter” boxing has the weapons bays. If doing an X-plane, those would have to be closed.

The decals in the Revell boxing are better than the original Panda offering.

FYI, the X-35A and the X-35B are the same aircraft. when the USAF was finished with their part of the test program, the lift fan was installed. The X-35A became the X-35B STOVL. The X-35C is the same basic airframe as the X-35A, but with a larger wing and horizontal stab area.

So I have learned since my last post. Now I am trying to see how much difference there is between the X-35A/B and the F-35A/B.

There’s quite a bit of difference between the two. The F-35 looks a little more refined for the mission. The X-35 definiately looks like a prototype to me.

Here’s a good comparison: SOURCE: CODEONE magazine - Lockheed-Martin

This pic is wrong, the APU Exhaust should be on the right side of the aircraft, not the left.

So basically the only actual option to make with this kit is the Edwards AFB flight test bird, with the mods you have made. Not the other options for projected operational JSFs.

Correct. If you want a production F-35A or F-35B, the two kits offered by Kitty Hawk kit is the way to go in 1/48.

Academy and Italeri just released their 1/72 versions, with the Academy being the nicer of the two. Hopefully Academy will produce a 1/48 kit…

I picked the Panda model about 7 years ago and I’ve just now gotten around to working on it. I kinda made a what if squadron marking. I’ll see if I can get a picture posted tomorrow of it.

Thanks for the enlightnement here Steve. FM, I would love to see your build here. There is a bug in my head about this build now… I picked up the R/G kit for 50% off back in '05 and it has been sitting in my stash languishing. I really wanted to do an operatinal bird (no more Sgt Yorks for me thank you) and was waiting for them to go into service before uilding it. But now armed with this knowledge, and I found that I have some very good reference on the original JSF X-planes in my library.

@falconmod: I would like to see your build as well.

@stikpusher: there’s a lot more mods that need to be done, but where how far do you go…when mine is done, it will be a decent representation of the X-35A, not an accurate representation. It will look good sitting on a desk or in the display case. That’s what I’m going for with this build.

Sgt. York!

My brother was assigned as a test engineer on the DIVAD program. As a mater of fact, his data was the data that was sent to then SecDef Weinberger to get the program cancelled!

Well I am not one who has to have the latest most accurate kit. A Monogram TBD dressed up with scratch work and generic PE will suit me over a Great Walls kit of the same subject :wink: So it is your bothers fault that my Sgt York build is a “what if”? LOL! I bought the Tamiya 1/35 kit when it was a new release (our PX was well stocked with Tamiya modern armor kits), and built it up in a nice USAEUR MERDC scheme, to match the rest of my collection at that time. But it never came to pass. I still have it, nearly 30 years later now.

If it isn’t too late, check the helmet on the pilot, the new F-35 ones are NUTS!
