I'm scratch building a #2007 Iris.

Am I just overlooking it or is there no BNC-50YR available? (balsa equivalent of the PNC-50YR, 4.125" ogive)

I bet Sandman can do either for a fair price.

Yes, this is what I was getting at. For the time and expense, why build a scale model of a poorly-executed kit of a scale model, when you can just build to scale? I agree that the Semroc BNC-50G is a better choice for profile scale than the plastic Estes nose cone. Good luck with the build... I "cloned" a Centuri IRIS kit, but made adjustments and added a few minor details to make it more of a scale model and less of a clone-of-a-kit-of-a-scale-model.

Jeff,
Estes sells that nose cone in the PNC 50 pack. Or I could send you one if you like, just let me know.

There are A TON of kits that used the PNC-50YR nose cone.
Hopefully you may have one, or can acquire a kit to kitbash an Iris.
See attached John Brohm's nose cone reference list, scroll down to pp 20-21.

Thanks! I might have at least one of those. I’ll look when I return from Montreal.
