Roll Servo & OAT Wiring

Not much to report today, aside from tidying up some wiring.  I routed the roll servo wiring up to the corrugated tubing and pulled it through.


On the left wing, I finally made use of the hole in the spar flange that is supposed to be used for Van's homemade pitot tube.  Since I went with a pitot tube that looks like it belongs in this century, I had the hole to either fill or use.  Luckily it's the right size for the outside air temperature probe.  I put the probe in place (loosely - it'll have to be pulled away a bit to paint) and pulled the wires through.  I haven't been able to figure out a super clean way to punch through the tubing, so my method of choice is simply a rough cut hole and RTV to hold things in place.  It's kind of odd - the instructions for the OAT wiring say that if you need to make the wire longer or shorter, cut it in the middle and splice more wire in.  The wires come pre-crimped to some tiny molex connectors that connect to the ADAHRS module, so I'm assuming the instructions are there because most people don't have crimpers that tiny to deal with putting new pins on.  The wire is barely long enough to reach the fuselage, so I'll definitely have to extend it.
