Yes, I never have finished my Nike Hercule CAD Model Build, but I'm easily sidetracked. Had an urge to look at the Nike Ajax, and I'm pretty happy with how it's going so far... I'll be able to re-use much of the Nike motor that I had finished for the Hercules. Really pleased with the way the tunnels came out. The only complex item left to do is the interstage. It was interesting to find out, that according to the Bennett drawing, the tunnels are different sizes.
