Inboard profile from same PDF appears to depict N336-7

After going over the same document, I think that the caption looks more like N336-2. What do you think?

I think so.

There's a vestigial dot between the dash and the 2 that *might* be the traces of a 1, in which case its N336-12 (which would make sense)
 
From my collection looking a bit aged... but cool design.

So the ATS design designation is N333-14. Nice!

We have


N333-14 - ATS, horizontal tail planes, AllysonCA's model
N336-12 - VATOL, single tail
N340 - no details
N3xx-14 - ATS, horizontal tail planes, in BillRo's photo of a model. Possibly N333-14?
N3xx - Twin tail VATOL design in BillRo's artist's impression.

I don't think the NASA Langley design is related though, Pyhrric Victory

The Saab design had good high AOA performance too. The main objections were difficulty of placing a second seat without disrupting airflow into the inlet, and possible problems with combined high AOA and yaw.

That would be my concern in general - I suspect one could make an inlet that worked well at high-AOA, but I find it very difficult to believe you could make one that worked at high AoA *and* a reasonable degree of yaw. All those images show straight-line AoA, which is great until you start to get near the stall boundaries.
