Wow, that's neat! The tubing in the kit was unique to that one kit, I wonder how much money MRC lost on that? Still, it's nice to have the designs, just have to make your own mandrels, then roll your own tubes.

If Carl was still around, he might have contracted out custom tubes!

No nose cone in that set. I went ahead and downloaded the MRC sized set which did include the nose cone. At worst I can just scale it to fit in the slicer. But was hoping I wouldn't have to do that.

Just finished up my version of the Trail Blazer. Used basswood on the main fins and built up the second stage fins. Played around with making the fin attachments using my 3d printer. Not to scale but helps give it a scale like appearance. Also made a 3d printed stand. Will be posting the 'accessory kit' to Thingiverse soon.

Made this model originally back in the 90s. Was nice to build it again.
