The pre-sheeted Alcyone has tow strips about a quarter inch wide that
run out behind the spar -- they're perfectly placed to cut into them
when you cut pockets for servos (rather than relying on the original
cable and torque rod setup). The wing should be strong enough for any

You wouldn't put it on the bias on the spar, you would use prepreg on
the spar.
The bias is for the wing.

Veronica,
Yep, it's true. Carb.com is telling me they won't have any in stock
until September at the earliest. Wick's Aircraft Supply or Aircraft

Carbon fiber dust is a very bad substance to get into your lungs. When you
cut it with a dremel you should, at a minimum, be wearing a filter that
prevents the dust from entering your lungs. At best, you should be doing it
in an environment that doesn't leave the dust
