Whoops again!  I searched for a suitable engine in the roughly 1000 hp range but smaller than the V-1710 and found nothing (how I missed the Continental, I don't know).  I came up with 1430 by determining the displacement of a ten-cylinder version of the V-1710 and rounding to the nearest 10.  Oh well, that's what happens when I get in a hurry.

Love the AVG version! And, since none of those 'Hyper' engines really panned out, your V-1430 would have to be a step up from the IV-1430  ;)

I agree!

Although I do find the radial version easy to get used to as well.  :)

Glad you like them!  How do you feel about the jet version?

The XP-12S is a hoot! Asbestos flying boots for the test pilot though  ;)

Beautiful but I have to ask exactly where the jet engine exhaust is.  Is it in carefully placed locations around the cowling (much as Focke Wulf did for the FW-190TL) or is it beneath the aircraft as on the Yak-15?

The jet pipe seems in the tail, engineer, like on a Mirage III.

I wonder if he meant that the methods used by the Fw-190TL and Yak-15 might be more straight-forward than having to re-arrange internal components to accommodate the tail jet pipe.

Quite.  Either seems preferable to toasted (or over-toasted) pilot.

I originally drew the Yak 15-style exhaust, but it was really ugly and ungainly to me.  Since this is really "just for fun," and that picture was "no fun" for me, I abandoned it and went with this one.  Of course I know it is pretty impractical, but it looks nice (at least to me)!

With a titanium pilot, it is very practical, and pretty and fun, all the best :)

Then one more vote for Fw-190TL-type installation, if you want to make another jet version (after Googling it a bit, it does seem to me the method that messes with the original look the least).  ;)

Well, OK, if you insist:
The XP-12S was totally unsuitable for squadron service due to uncontrollable cockpit heat, plus the overcrowded cockpit.  The aircraft was, however, extremely maneuverable, and the five service test versions (YP-12S, later re-designated YF-12S), were sent to Fürstenfeldbruck AB, Germany where, after brief testing, they were used to form an aerobatic team, the Skyblazers, which eventually became the official aerobatic team of the US Air Forces in Europe (USAFE).  The three-aircraft team flew the YP-12S for only one airshow season in 1949 before they were replaced by F-84G aircraft. 
Meanwhile, an improved version was developed which used design features gleaned from documents captured from the Focke-Wulf company in Germany.  This version, the P-12T, was only slightly more successful - though it solved the heat and crowding problems, it was still very short ranged and had a slow top-speed for the day. 
Shown below are a Skyblazers YF-12S and a test XP-12T.

I would have thought the XP-12T prefers a T-tail, but the flame trace seems to show this is safe like that. :)

Hmmm .... the T-tail from the Ta 183 Huckebein would look awfully nice (and maintain the Focke-Wulf connection). An XP-12T-2 perhaps?

YF-12S and XP-12T are some fine imagineering, paint and all  :-*
They do look airworthy and either money worthy to build after a major lottery win.

I can imagine a centrifugal flow turbojet in the XP-12T...... and it feels awesome!  :-*

OK... seems a little crazy to me, but here is the XF-12T-2 with Huckebein-style tail, as well as the XF-12T-3 with further modernization.  In 1948, Boeing finally gave up on the biplane configuration and created a monoplane version, the XF-92 (I have included the original P-12E starting point to illustrate the extent of development [LOL]).
