I used a piece of maple for the rear rail guide with the nut recessed and epoxied into the back of it. The forward rail guide is screwed into the FCR. I'm not sure how far apart these rail guides need to be, but for a 80" rocket they look too close together. Right now they are 15-1/2" apart.
It'll be fine.
My old (now retired) PML Endeavour had 14" between the buttons on ~70" length. Always flew great.

I guess that I should dig out my old Yank 4" IRIS then... Since all the pictures of it in the Yank gallery disappeared with the changeover.
It was a good flier. Handled any K that I could put in it. I didn't glass it, just foamed the fin can.
Yank IRIS instructions . . . PDF's below.
