Don,

As far as I know, #7 was #4 after being sold and repainted. #4 (the most famous and most-modeled) was red or brownish-red with cream trim. Mike Helsel of the Dallas/Ft. Worth area consistently used this color scheme on his "old" Formula One racing models for 20 years or so. (Mike also happens to hold the AMA record for the "old" F1 at 1:04 or so, a record which ought to stand for some time since the event is no longer flown. )

My prototype Cosmic Wind, pictured on my remedial Web site, has the correct base color (blue) and the correct race number (#7) and registration number (N20C, same as when it was the red #4) ... but I took some liberties with the color scheme. Apparently the new owner succumbed to temporary insanity and painted it solid blue without the trademark "minnow stripe" down the side of the fuselage like on the red, green, and gold Cosmic Winds. I corrected that oversight on my model. (Another )

BTW, I'm told that one of the Cosmic Winds was actually entered in an International Aerobatic Club contest, once, back in the '60s or '70s. So it would be legal for IMAC. And that's good because the darn thing does terrific akro. Spectators sometimes ask me if it's a Chipmunk or CAP.
