I spent most of my afternoon tracking down parts to fix the latest problem with a vehicle, so I didn't spend much time with the plane. I started out by organizing and tightening down all of the terminal block screws. It's definitely a lot bulkier than it would be if I just used one of those circular connectors to tie the wing and fuselage wiring together, but the terminal blocks are simple and inexpensive and future modifications will be easy.
One thing I don't love is how thick the clear heat shrink tubing over the labels is. It looks good, but when you have a bunch of wires together and the labels are all in about the same place, the diameter of the bundle really changes and makes for a messy look. I'll get over it though. I glued a small cable mount to the floor to hold the wires down and forward before they go up and through the first rib hole. The aileron pushrod will come through this area, so it needs to be able to keep clear of anything that could bind on it.
The design of where the wire holes go in the ribs isn't well thought out. Right in the middle of two of the holes is the control column mount. A lot of people drill brand new holes at the bottom of the ribs a few inches back from the spar, but I decided to keep the original holes and bend the wires around the mount. It obviously wouldn't take long for the sharp edges of the mount to chew through the wires, so 3D printing to the rescue again!
In 5 minutes I had designed a couple of plastic pieces to slip over the edge of the mount (just glued in place with Goop - basically contact cement on steroids. It's amazingly strong once it cures for a few days). I love that 5 minutes of CAD work and an hour of printing gave me a solution that kept me from having to drill a bunch of new holes in the ribs. I didn't get any pictures of these in place, but I think they'll work fine. I wrapped a little silicone tape over the wires where they cross the plastic as well. I designed a little lip in the top and bottom to make sure the wires didn't migrate over the plastic and onto the aluminum mount.
