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.
Ok, good. I'll leave it as is.

There's some great info and documentation in that thread. Thank you for posting that.
