 I have used this often in the past to connect elevators, rudders and
 ailerons:  http://www.aircraftspruce.com/catalog/elpages/copperbraid.php
 
 Put on some quality terminals and make sure you are getting good contact
 directly to the carbon.  I am including a pic of an elevator that I
 connected to the wing skin.  You want the ground strap to be long enough to
 allow full movement and have it run somewhere where it won't bind with
 anything.  On the elevators, we connected to the fuselage on the joggle of
 the inspection plate cover (countersunk #10 screw with a locking ms nut).  I
 can't remember exactly how the strap connected to the elevator, maybe
 someone else will chime in here, but I believe we just put a counter sink
 screw through the lower skin (before paint).
 
 Just as note: on carbon structures, resistence from the static wick to bare
 carbon on the front of the plane (the cowl joggle for instance) can be as
 low as a few ohms!
 
 Have Fun
