That's cool that a Cosmic Wind was entered in an aerobatic contest.
About the real planes ... I heard that the #7 was built from parts from the Minnow plus parts from 2 others that had been started. Or that may be the Ballerina story ... can't remember for sure.
It's funny that you mentioned that #7 was all blue because I came across a picture of it somewhere and almost didn't recognize it as a CW until I looked closer.
BTW, additional CW's have been built ... one was up for sale in one of the GA plane mags a while back ... it had a Lyc 0-320 in it though.

It is probably the one that was entered in the akro contests.
Now I want one of your planes ... didn't you say you have molds for the fuselage now?
