I finally had no excuse to delay starting the elevator pushrod instalation. I have been very weary about cutting into the fusalage for the pushrod exit and have been doing everything else I could before tackling this.

Although I know that people have had minimal problems with the DEPS system from Central Hobbies or something similar I have a mental block about using the .07 carbon fiber rods. I had decided to use .125 carbon tubes instead. They are a bit stiffer and should require less supporting structure. The fuse exit structure was an issue however and what I finally used was different from what I planned on from the beginning.

I decided to mount the pushrod before mounting the servo or horns. That way the horns could be mounted at the proper distance from the fuse rather than trying to line up the pushrods with a pre-existing horn. The pushrod could also be made parellel to the stab and the servo mounted at the proper height in the fuse.

I started by marking the center line of the stabs and measuring down front and back the distance to where ther horn connection would be. That way the pushrod is parallel to the stab. By continuing this line foward I have the pushrod exit line and height at the sevo arm connection as well.

Using a straight edge from the center of the servo area as pictured in Troy Newman's DEPS installation article I found the the pushrod should exit right at the rear former which I also marked. (not shown in picture)
