Does anyone have anything on the Straight-Wing mock up for F-86? TIA

No it was different - the only similarity was the straight wings.

Nope. The FJ-1 was NA-134, the XP-86 was NA-140. The straight-wing XP-86 apparently was NA-136 [it wasn't*]. Actually this was discussed recently in another thread. Are you sure there was a mock-up, anyway? Here's an illustration, which I suspect is a later composition, not an original NAA illustration:

I saw a mockup picture of the airplane in question and it had MX-673 on its nose.

From "Wings of Fame" Volume 10 Page 38:

"The straight-wing project proceeded as far as a wooden mock-up of the left wing and fuselage, complete with dummy J-35 engine. It was unveiled at Inglewood in June 1945"

Justo, you've been posting without citing sources again

The pic can be found from this source:

I think that you will find, under closer analysis, that the Squadron/Signal "XP-86" drawing is much closer to representing a FJ Fury than an XP-86.

This is also what I thought, but until we get a proper NA-136 straight-wing XP-86 profile, I guess that's the closest we're going to get...

The XFJ-1 had the same wing-mounted dive brakes as the XP-86. This was changed for production to the fuselage-mounted brakes, reportedly due to a roll-control incident on a test flight following a jam of the wing-mounted brakes on one side. The FJ-1 engine was also removed through the top of the fuselage rather than removing the aft fuselage, apparently to minimize the deck space required for an engine change.

Hey Stargazer and Pometablava - a little off topic, but do you have any profile drawings of the TF-86 two-seater trainer variant of the Sabre, which NAA built as a single prototype????



Regards
Pioneer

There is a topic on this very forum with lots of pics and a profile drawing:

I for am glad they abandoned the straight wing concept. Otherwise we would have never gotten these beauties.

Scans from:
Evolution of the F-86, By Morgan (Mac) Blair
AIAA Evolution of Aircraft Wing Design Symposium, March 18, 1980.

Figure 5 shows the P-51H, XFJ-1, and original XP-86.

Figure 11 shows the initial wind tunnel configuration with alternate wings with aspect ratios of 5 and 6; and unswept tail.

Figure 13 shows further refinement; fuselage cross section has been revised.

Figure 18 shows the relationships between the wings of the North American fighters.

I recently acquired a number of NAA Columbus FJ Fury photos and amongst them was this photo of the XFJ-1. I'm posting it for the sake of completeness/comparison on the topic since the production FJ-1 differed in detail.

Enjoy the Day! Mark

The designation NA-136 did NOT apply to the straight-wing XP-86 project as previously suggested.

Forum member Steve Pace reveals the allocation of that designation here:
http://www.secretprojects.co.uk/forum/index.php/topic,665.msg171934.html#msg171934

I have edited my posts and apologize for the wrong assumption.

Does anyone have, or know where to find, dimensions and drawings of the North American NA.140, the later F-86 Sabre, only with straight wings? Thanks in advance!
A SPF thread


Thanks for the clue !

The recent Hatchette bookazine on the F-86 has a lovely-sized three-view of the straight-winged proposal along with mock-up pictures and a picture of a desk model. It also has a three-view of an intermediate swept wing study that retains the straight tail surfaces.

Would anyone be interested in a 1/72 kit of the straight wing NA.140 version?
I, for one, would. Been looking at crossing bits from a F-86A and a FJ-1 as the starting point for modeling one; a kit would be simpler.

Thanks for your input! I'm putting together our latest production list and your feedback really helps!

A single photo of the straight wing XP-86 appears on page 6 of "WARBIRDTECH Series: North American F-86 SabreJet DAY FIGHTERS, Volume 3. The caption reads: The only known photo of the XP-86 straight wing design at mock-up, which was unveiled at Inglewood in June 1945. Only the left side of the mock-up was finished and inspected on June 20, 1945. Although the XP-86 never went beyond the mock-up stage, its Navy cousin, the XFJ-1 Fury went into full production, becoming the first operational jet fighter for the Navy. (NAA)"
