More Wire Tidying; More Strobe Wiring
More wiring stuff today. I'm tidying up all the wires in the fuselage. Here is the run in the center channel between the two seats. Nope, I don't have a whole lot of wires in here. You can see that I'm using the plastic tie wraps. I'm using two different sizes, one is larger and actually has a whole in the middle of it that fits the countersunk aluminum pop rivets I have perfectly. If I start having problems with these things falling off I'll just pop rivet them on. I'm not putting any of these in any sort of sealed off location.
Here you can see where I tied off the strobe wires. For whatever reason, the strobe kit comes with leads on the power plug. This seems sort of odd to me and there was nothing about it in the documentation. I didn't want to have an unnecessary splice (more potential points of failure) so I removed the pins from the connector and installed new ones.
Unfortunately by doing this I have used all of the male pins. No problem, right? Just use the pins that I have with my other connectors. Nope! They're not the same. Dadgummit...got to find out the part number and order some more of those pins for the strobe power supply. I may just ask around and see if anyone has some of them. Surely someone does.
If you happen to be reading this and you have three male pins you would be willing to part with, please give me a shout.
Also in this area you can see that I have the shields pulled out and I'll be tying them together and grounding it. I know that some people run the shield grounds all the way back to the central grounding location, but the installation instructions for the power supply say "Ground on airframe at power supply ONLY", which is precisely what I aim to do.
One thing I did not get a picture of tonight was the work I did on the aileron trim servo. I removed the d-sub connectors (but left the pins) and put the pins together, put some heatshrink over the individual connections then heatshrunk the whole thing together. I thought this was overall a better maintenance-free approach since it will provide superior vibration isolation for those tiny wires. Many other folks have done this and have been flying for thousands of hours with no problems.
