For a carbon fiber airframe, with all the pieces electrically bonded together, I can see how wicks on the TE's could keep static charge density down over large areas, but I can't see how on the ES they will do anything but dissipate a little charge over a very confined, local area. The conductivity and dielectric of an e-glass composite is probably not very different from air, and as we all know from shuffling our feet on a carpet in the winter, we need to get very close to that doorknob, maybe a millimeter or so, before the charge dissipates (Yikes!). Am I missing something here, or are the folks buying wicks for e-glass frames wasting a lot of money?
