Brief Description:  Trim Servo Re-Do

I really just hated the way I installed the trim servo power/indicator cable. I orginally ran it through the manual cable route and quickly learned that the cable would be a close neighbor to the trim servo jack-screw. It would have only been a matter of time before the jack screw munched through the cable and made my trim inop or run-away.

So, I sat and stewed and brainstomed about it. Once I had a plan I call Van's Aircraft tech support and discussed it with Gus. He gave me the nod and I installed it the way I show in these pics. The routing this way is far better since the wire enters the elevator almost adjacent to the trim servo pigtail. No binding, rubbing, sharp bends, etc--very clean. I like clean. I'm going to remove the snap bushing shown in Pic2, since it's too small to pass my inline connector through. I'll probably enlarge the hole and split a rubber grommet for this passthrough.

Pic3 shows the wire in relation to the vertical stabilizer. I still need to install the inline connector and lock it down and beefup the insulation to handle some chaffing at the cable ring.
