The instructions on the routing of the elevator servo wires at the tail section is a little vague. First, are they secured to the inside of the elevator leading edge skin? After coming out there, it looks to me like going over the rear stabilizer spar would be the best way? However, without drilling a hole in that spar to secure them, how could they be secured over that spar so they wouldn't be just laying there? If you put the wires under the spar, the connector would really be in a confined space. Thanks
