Republic XF-12 Rainbow

[GeorgeA]

50-60000 feet?

Makes you wonder what the **** kind of air defense threat they were thinking about.

They were ambitious in those days. The original spec for what became the B-36 called for a 45,000 ft ceiling, 450 mph over the target, and a 12,000 mi range — in early 1941.

Apparently PAA failed to keep Jimmy Steward out of the cockpit. Ah, what might have been.

Again, a great video done by Mike Machat.

Adding a minor footnote to this thread.

The RC kit of the XF-12 posted by zbrubaker early in this thread is now out of production and the business has closed down. Through a friend, I was able to locate and obtain one of the kits (actually a semi kit), which are now unobtainium, and hope to add another flying example of this model to the skies someday soon. The Rainbow is, in my opinion, the most beautiful four engine prop aircraft ever created (even allowing for the lovely Connie)

All the pics here in this thread will be a huge help.

I did a micro scale RC XF-12 back around 2005 that used tiny RC equipment and tiny electric motors. The model was 1/72 scale and flew great, even at this tiny size.

To add a bit to the knowledge base. Every drawing I have seen (plus the Anigrand 1/72 scale resin model) has the rear of the engine nacelles shown incorrectly. They are depicted as round when they actually taper to a oval shape, with the long dimension set vertically.
