There isn’t a super-convenient way to route pitch trim and magnetometer wires into the empennage, so I improvised…<\/p>\n

Here’s the pitch trim servo wire exiting through a lightening hole in the fuse rear deck.<\/p>\n

\"Routing<\/a><\/p>\n

I liberally applied adhesive zip-tie mounts to the rear deck and glued a small piece of aluminum angle to the rear spar with 3M 4000 marine cement (easier than riveting) to hold another zip tie.<\/p>\n

\"Pitch<\/a>The black material is self-closing anti-chafe wire bundling I found at McMaster-Carr. The plans call for running trim wires along the front of the left elevator and into the trim servo bay. I think this is better than running wire through the existing manual trim cable holes as repeated elevator movement over time slightly twists the cable rather than bending it – much better from a wire fatigue\/failure perspective.<\/p>\n

\"Routing<\/a><\/p>\n

You’ll see in this picture how the trim servo cable is routed into the left elevator and why some support is necessary where the cable crosses the HS rear spar.<\/p>\n

\"Pitch<\/a><\/p>\n

And here’s the wired trim servo ready to be stuffed into the elevator. It’s slightly tricky to route the cable so it doesn’t interfere with the servo’s jack screw, but I think I’ve managed to get everything done correctly.<\/p>\n","protected":false},"excerpt":{"rendered":"
