Static than Lancair's other offerings. To wit, the entire skin is carbon
fiber, including the tail, rudder and cowling -- save for the last 18 inches
of wing tip, which is E-Glass and contains the nav antenna (in both wing tips
if you have an early kit, in one tip for later ones). I plan to use 2 wicks
on each outboard flying surface for a total of 10 (my old Skymaster had 27
and still immediately lost the Loran upon entering any precip).

Using a simple Ohmmeter, I find I am getting about 25-30 Ohms per foot of
separation on the Legacy skin. Of course, it is hard to get solid readings
with probes but they are solid if probed on metal fastened to the skin, such
as rivets holding nutplates. I find the same resistance between epoxied
fuselage halves, so the continuity is good, but the resistance is high (not
as high as E-Glass). The elevators, rudder, ailerons, flaps and cowling wil
be bonded to the fuselage and the braided ground line running at the trailing
edges of the wings, H-stab and V-stab.

The wick mounts and other skin to braid connections will be epoxied with a
flox made of finely chopped (minced, diced?) carbon cloth and Jeffco.

Any comments would be appreciated.
