Quite right Simon, they do on panels to dissipate the energy,
but it is no good as an insulator.
Have you got your Q back in the air yet ? Are you a GU or LS1

Most manufacturers of aircraft these days use Astrostrike LSP,
which is an expanded foil mesh which is laminated between the
layers of composite material.
The modern carbon airliners use glass pads as
insulators for lightning strike, so as the carbon spar is
wrapped in glass, it should be insulated from lightning
stike I would have thought.
Just my 2 new pence worth, (which is also a good coin
for tap testing).

Any Q is faster if it is lighter and
more power is added. Those factors are probably more
important than the airfoil.
VG’s on the GU solve the
rain/contamination problem, but are a pain when trying
to keep the canard clean.
LS-1’s break too, but just outboard
of the fuselage instead of farther out on the wing.
There are several GU’s flying with
O-200’s on them, so I suspect the QAC change from GU to
LS1 was driven more by contamination problems than by
strength issues (despite what was said in the QAC
I am not sure that the speed of GU vs
LS1 has ever been fully resolved, but there are a lot of
fast GU Q’s that have been built with a variety of
engines (Corbin’s is a very fast Q200 and has a GU
canard. Paul Spackman’s Q2 with the GU and Jabiru engine
is/was also very fast). More LS1’s have been built
because of supply, so the sample size is larger and
probably more is known about them because of that.
……The GU will not explode if hit by
lightning, since no carbon fiber.

In my opinion... 1) the GU spar
ends 4 feet from the wing tip. Lots of them break
there on a hard landing. 2) It wasn't designed to
carry an 0-200A (but I don't know what your running
for an engine). 3) if you never fly in the rain your
ok. And I challenge that the GU is faster? The
fastest Q out there is Sam and he's an LS1.
John, PM me. I'm on the q
Facebook group too if that's easier.
Mike, it's faster, and my LS
one is already a little damaged. Plus I'm doing
some fairly major changes and replacing my
firewall already so seems a good time. Faster is
legit the only reason for me wanting the swap. But
I'm open to hearing reasons not to change back and
to keep the LS.

Yup. Located 40
minutes from Salt Lake City on I84.
I'm curious why
you would switch that back.

Anyone or there
have a decent GU canard sitting
around for a Q2? Tossing around
the idea of swapping my LS1 back
to that. Not fully decided as of
yet but if there's one laying
around for the right price that
would save me making a new one it
might twist my arm.
