Hi Bruce;
That is the "big" Cosmic Wind that Testors put out, and I have one hanging in my basement also. They had another one that was smaller that is of great interest, as it is EXACTLY the same as the Cosmic Wind that Cox put out, only difference is the engine mounts. All parts interchange. I figured this out after picking up examples of both. I know this was discussed a bit on the Cox Engine Forum as to which came first and how and why this happened., but I would have to search that out to reacquaint myself with the details. Makes me wish Wild Bill Netziband was still around to ask about this, as he was working for Testors at that time I believe, and I don't remember if Larry Renger knows anything about it. The small one looks cool, but is made of a softer plastic and is deformed easy. The bigger version looks just as good and looks like it would fly better. If I ever run into another one, it would be a candidate to fly. I run into the engines from them still attached to the firewall, and what is unusual about that is that the is a 3/8" nut and bolt added to it for balance weight! That just looks like something Wild Bill would do, a simple solution to a simple problem, just run down to the Hardware Store for some nuts and bolts, and hole in the firewall and you are good to go!
Type at you later,
Dan McEntee
