Both left and right leading edges have been assembled but not yet attached to the main wing spar. We are waiting to attach until after we put in the Duckworks HID light kit. We're waiting on the mail to arrive with the documents that were missing from the light kit and as soon as it gets here Brandi is project leader for lights because shes bright so she'll get along well. In the meantime, it was handy to stack the leading edges under the main wing spars on our wing stand.
