We've got some but it will take a few days I think to find where the pics were archived.

These below though I took when I was coming up with an idea on how to make a much better fixture.  The bolt hole I'm measuring is one of four where the wing gets bolted to four corresponding lugs sticking out the bottom of the fuselage.

Incidently, how the aircraft comes apart is almost how Airfix has the way the kit gets assembled, I found that very interesting.
Four bolts tying the wing to the fuselage?  Interesting!!  Both the P-51 and the Learjet are set up that same way.

If there was any others Evan, I didn't see them, or I don't remember where they were.  The wing was all in one piece, there was a notch in the bottom of the fuselage which had a flat surface at the top with four lugs hanging down from it. The flat surface was also the top of the wheel bay.  I was shown some 'special' material bolts which were used for the bolt-up and I had a couple new ones made which were a bit longer as I used a 1" thick steel plate to span from one bolt hole to the other (that you can see in the top photo). We then cut some slots in the flat surface through to the engine tunnel above it so that additional steel plate could protrude though and get welded to the main steel plate, these were then bolted to the ends of the pipe which came through the engine tunnels from the rear.

Oh, I have no trouble believing it because, as I said, I do know of other aircraft done the same way.  Considering that one of the fathers of the Mustang, Edgar Schmued was also involved with the N-156, it doesn't seem surprising at all.

Random idea:  Netherlands F-5E in WW2 markings with these Roundels:

Persian Independence Air Force markings?

Iran = Persia and vice versa, also the population of Iran is over 60% Persian and they are the
dominant ethnicity in all ways ... so from whom are they claiming independence?

Or are you positing a Persia that was conquered and remained under the control of the Ottoman, Mughal
or Russian Empire?

1/32 T-38 would make into cool 1/72 transport !
But there aint one far as I know.

It would be a rebel force against the current administration(s) found in that land.   The F-20 would be pitted against the indigenous F-5 derivative that's been developed.  (whatever that aircraft is called, I don't remember its name at the moment).   

Or it would be a force against a greatly enlarged Khemed that a much older Tintin would cover.   Khemed would have a swept wing MiG-21F and the Persians  the F-5E/F.

Rather than the N-156NN, it likely would've been a later design development, the N-251B which had a raised cockpit compared to the N-156 and increased wing area.

Do you happen to have a line drawing for this?

(Assuming it doesn't have anything to do with the first post in this thread...... by mentioning N-156NN again I am looking for a CVE-compatible fighter jet......)

Unfortunately, I didn't borrow and copy that brochure when I had the chance (co-worker on a classified program there had it and getting things in and out was a pain at times).

Regarding a 1/48 T-38, didn't Fujimi do one?

Given the similarity between the T-38A and the F-5B, I'd expect it to be AFV Club along with all their other F-5 kits.

Am I the only one who thinks that naval concept looks a bit like the outcome if an F-5 knocked up an Su-25 Frogfoot?

X-29 with F-20A cockpit and nose with vectoring LO nozzle on a F414.  Four or six underwing stores points with pylons shaped to avoid the moving portions of the wing.

Great concept, Evan. And very doable. Please, refresh my understanding: "moving portions of the wing" as in control surfaces, or as in parts that don't flex inflight?. And what's the shape of that 2-D nozzle?, I know I've seen it, but can't precisely find it.

The X-29 has a flex wing wherein the forward and aft sections of the wing flex as flaps etc. to improve performance; the intention would be for the pylons to not interfere with that.  The pylons would attach to the fixedm iddle portion of the wing and be shaped to miss  the maximum deflections of the flexing parts.

Basically, I'm thinking of a GE equivalent of the combined AVEN and LOAN programs (both of which used P&W engines).  I'm certain GE has similar efforts and I'd wager that the F136 used at least the LOAN aspect.  you'd mainly end up with s trimmed rear edge of the nozzle much like what is on the F-35's nozzle and the nozzle would be a "glossy metallic black" in color, showing the "special coatings" applied.

Would it suffice to attach pylons with reduced area, like an F-16's external wing stations?. Aligned with the wing centerline, lenghtwise?. 3 to four such is ok?

So, are you describing a serrated trailing edge version of the F-16 VISTA?. Of course, in F-404 size?

Ok, I found it:


That, along with the tigershark nose and cockpit/canopy change should give the X-29 a very menacing look. Beautiful!

I'd have to look at a X-29 kit to see what good references there are; let me get back to you on that.

Yes, a serrated trailing edge nozzle fit to the F404 or F414 (same engine envelopes, so one should replace the other).  I'm thinking three stores stations per wing, likely with drop tanks on two and the other four for armament.

When If I finally get round to building my operational X-29, I want to modify the main landing gear doors to allow a centreline pylon for a tank or ECM pod.



This is how it would look. Kinda.

That makes sense, a bi-fold door hinged outboard as opposed to an inboard hinge.  I'd have to look at the kit to see how feasible it would be.  Still, with the MLG trunnions where they are, I'm not sure how large a store you could carry on the centerline.
