That's what is great about the KR. You can do just about anything you want.
I've used 1/8" Okome on my fuselage and am very happy with its workability

For the spars you must put the primary grain of the plywood in the vertical.
Plywood comes in 4-foot widths, but you need more than 7-foot width. So,
you need to scarf 2 pieces to get the width and keep the vertical

Woh, now there's something I missed. In all my perusing of the plans and
the build guide I hadn't noticed the floor extending back past the main
spar. I'm at the point of fitting my centre section spars so I'm glad this
came up. KRNet saves the day - again!

There is no 45 degree plywood called out in the KR plans, except the little
gussets around the main and aft spar inside the fuselage (so use scaps of 90
degree turned 45 degrees there), so yes, 90 degree is what you'd order
"would use the 90 degree. Am I correct in this?"
If memory serves the 45 degree plywood is used on wings for torsional strength.
Which is the same reason the KR uses the fiberglass weave on a 45 degree on its
wing. Your 90 degree orientation should be fine.
