Bob,

The good news is that because you're building an EXPERIMENTAL airplane you
don't "need no stinkin' certification". The bad news is that lightning
doesn't really care and that the holes punched into radomes will be the
holes punched into your ES. A Stormscope is as essential as a turn
coordinator if you want to fly IFR.

I have built the extended range tanks without the speedbrakes. If the brakes
fit forward of the forward spar, it should be ok. If not, you may have to
build a wall around the speedbrakes in a similar manner to the dyke around
the pitot tube in the LIV with extended range tanks.

[Installing speedbrakes into an ES should be very similar to the procedure
used in the IV and IV-P... the pockets need to be located at a BL location
that will position them outboard of the ends of the stab, and about 60%
aft on the chord... on the IV they're located just forward of the rear
spar starting at BL76 and going outboard from there.  I would heartily
recommend a call to the factory to get their input on the exact location
for the ES wing, as it is considerably different than the IV wing.  I hope
this helps...

And regarding lightning protection, I'd suggest that you search the 
archives for "lightning" as there was a lively discussion of the subject 
in the LML about a year ago.
