No shooting this time... this puppy is unarmed. But there don't seem to be many of these around on SP, and it's such a beautiful plane.

The Republic XF-12 Rainbow was a four-engine, all-metal prototype reconnaissance aircraft designed by the Republic Aviation Company in the late 1940's. Like most large aircraft of the era, it used radial engines—in this case, the Pratt & Whitney R-4360 Wasp Major. The original requirement for the aircraft came in 1943 from the USAAC Air Technical Service Command, stationed at Wright Field. They wanted a reconnaissance aircraft which could do 400 mph at 40,000 ft, and had a range of 4,000 nmi. Its primary objective was for high-speed overflights of the Japanese homeland and key enemy installations.

Unfortunately, only two prototypes were built before the project was cancelled. By the time the plane was ready, the war was over and there was a surplus of both Boeing B-29 Superfortress and B-50 types to meet the long-range photo-reconnaissance requirement until the far more capable Boeing RB-47 Stratojet was brought into service. The B-29's and B-50's gave the U.S. Air Force less costly "off the shelf" options.

Had the XF-12 Rainbow been available in 1944, it almost inevitably would have been ordered in quantity... but as it was, the XF-12 disappeared into oblivion, despite its graceful lines and high performance. The Rainbow remains the ultimate expression of multi-engine, piston-powered aircraft design. Its high speed, near-perfect streamlined form, and neatly cowled engines make it a design classic, often unappreciated, and not very well known. The XF-12 was the fastest, four engine pure piston-powered aircraft of its day, and the only one ever to exceed 450 mph in level flight.

So, for my 1234-build; the F-12 as its production models would probably have looked in their reconnaissance livery.

Since it's a recon plane, there are very few special controls; AG1 for the lights, and that's about it. All the rest is standard (VTOL down for flaps, Trim for trim)...

Enjoy!
