The pictures keep looking the same from day to day, but I promise that it's the picture of progress! More head scratching and many hours just standing and staring led me to do a little more shifting of wires in the front center tunnel. The driving force in all of this thought and moving things around is to try to minimize parallel runs of certain wires with each other, the worst offender being the transponder coax. From what I've gathered, it's an extremely potent system, and if there is going to be interference, it's going to come from the transponder. The RG400 coax is double shielded and really should be fine keeping in/out any interference, but occasionally people still have problems with it. The RV is so small that I can only do so much though.
As best as I can tell, I'm done with the run going up the left side of the tunnel. I re-zip tied the wire bundle for the 50th time and put some spiral wrap on it to give a layer of protection between the wire and the floor. The right side bundle is all ready to finish up, minus one last group of wires from the ELT. I'm waiting on some shielded wire to arrive to finish that ELT/GPS connection, then I'll be all done with wiring to the panel.
My first approach to attaching the flap position sensor clevis to the flap control arm was to just use a small piece of aluminum held by a single adel clamp and bolt. That was probably a fine approach given that the position sensor requires very little force to move, but I didn't like the fact that the piece of aluminum could potentially rotate around the bolt if anything loosened up. I remade this piece (that the position sensor clevis attaches to) so that it is now held rigid by a second adel clamp. Now there's no way it could rotate around the aft bolt and cause erroneous flap sensor readings even if the bolt loosened up.
I think I finally landed on how I will route the static line up to the ADAHRS. I'm just going to zip tie it to the canopy latch teleflex cable to take it from the longeron up to the top skin and ADAHRS. The teleflex cable is relatively rigid, but will still vibrate, so I want a way to hold the ends of the static tube as it enters the T (the T is in place to also allow the static line to go up to the panel for the G5). I made a mount that the T bolts to, and extended it to also have a snap bushing. The mount will be riveted to the longeron. Even with vibration along the teleflex cable, the snap bushing should isolate the T connection enough...I think. My other option was to put the T further aft and run the static line up a bulkhead then forward to the ADAHRS. There was nothing wrong with that approach, I just had to choose one.
