Hi All
I think I am qualified to comment on this one with a degree in forestry and
a diploma in Timber technology!
If it came from a reputable source the spruce you will be using for your KR
will have been kiln dried, as long you keep the timber dry it will not get
infected with fungi.

Sharing this which seems to speak to the issue, although I still have more to
learn: (It's a PDF which can be saved)

I have a Mustang 2 with the big flap that extends all the way under the
fusalage essentially making that portion a split flap. The Nanchang
CJ-6 also uses this configuration. I can say that it is very effective
on the Mustang 2. Like the KR, it does not have a lot of span on the
center section
If you buy your spruce from Wicks or Aircraft Spruce you shouldn't have
any problems.

Hi All, an A friend of mine (and aluminum experimental builder), mentioned
some spruce fungus issue that if not caught can be disastrous. Is this an issue
with the materials, and if so how to inspect/avoid/prevent?
Thanks
At the risk of making a fool of myself, I bet he's confusing diseases of
living trees with lumber/wood preservation and protection.
Fungus can attack most any unprotected or ignored wood or wooden
product, so some sort of protection is required for longevity. Varnish
was the old standby but now
Here's a Jack Cox article on Randy Hebron's KR-1 taildragger with full
span flaps and spoilers. If the link is broken just take the space out.
