The cloth is placed on the mylar and wet out on the mylar, not on the
balsa. It's a lot easier to wet out that way with an appropriate amount
of epoxy. If you wet things out on the balsa, the wood will soak up a
lot of excess epoxy and you will end up with a very heavy tail. The
only thing you will wet out on the balsa will be the leading edge if you
want the glass wrapped around the LE. That step is necessary for foam
cores, but you really won't need to do that on a solid balsa stab.

I'm planning to vacuum bag some fiberglass cloth over some balsa v tails I'm
preparing for the Shrike I recently acquired. I want to do the v tail with
fiberglass because I feel it would make it a bit more durable. I have the
basic vacuum bagging system from ACP with the vacuum bag, Mylar, mold
release, etc. How do I go about it in prepping the balsa tail and
fiberglass cloth? Do I go ahead and trim the cloth to as close to the size
of the v tail pieces, wet the cloth out, lay it on the balsa, then stick it
in the bag with the Mylar sheet over the balsa/cloth pieces? I would really
appreciate some experienced insight on the process.
Aloha to all on RCSE.
