Yep. Going with a 29mm mount (using an LT-115 series tube). The nearest ring off of erockets that matches the 1.4" diameter of the FSI is the SEM-CR-115-150P at 1.5". But when you do the math off the scale drawings, the narrowest part of the tail cone is 14" which works out to be 1.75" @ 1/8" scale. Its quite perplexing as to why the tail cones are/were made so narrow.

I've come to realize the FSI kit is only semi-scale. I just thought it may be a little closer in scale than it is (the nose cone is perfect). Just one of these things you find out when you nit-pick the details. End the end, I'll probably put it together knowing the fins are a bit undersized as well as the tail cone and appreciate it for what is it - still a **** good looking sounding rocket!
