Scott & Tanya Card RV9A build log (N4822C)

Still at it. I’ve still been cleaning up and finalizing a bunch of wiring runs and details (anti-chaffing) in the center floor in prep for installing the rudder pedals. I also did even more trimming on center tunnel cover for the wire bundle transitions. I removed the instrument panel and got it painted. It looks pretty good. I sprayed it with basic rustoleum gray then baked it in front of a couple of space heaters. I glued the pitot tubing to the floor in a couple of places and secured it with adel clamps up the left side fuel vent line. Also, the parking brake cable is secured. Lastly, I got the pedals in place. That was quite a trick but possible. Now I’m just finishing up securing the brake hoses. Then I think the instrument panel will go back in for the “final” time. That should be exciting.

 

  

  

  

  

  

  

  

  

  

  

  

  

  

 

I’ve been working diligently to clean up and finalize all of my wiring bundles. I’ve been wrapping some stuff with silicone tape, replacing temporary (oversized) adel clamps with the final correctly sized clamps with final bolt attachment (not fun at all). I’ve been resolving minor routing conflicts, etc., etc.. All very small, very time consuming details to get from the wiring “process” to the flying state. I’m also taking a small step back to fabricate brackets to secure the rear of the radio stack to the sub panel. This is a bit of a trick since the screw holes in the trays land dead center of the sub panel, so the angle to put the screws through for attachment has to be secured with spacers away from the sub panel.

I also got the nylon screws that secure the magnetometer installed.

 

  

  

  

  

  

  

 

I’m working on completing the remaining unswitched audio input signals into the audio panel from the AOA, EFIS, and EIS. I tested the AOA signal for the first time. I decided it was a bit too loud. There is a very small POT on the CPU board for the AOA that adjusts the output gain. So, I opened up the case and adjusted it. There is currently no audio output from the EFIS but the wire is there and there is a note in the documentation that it may be used in future software releases and that its output gain will be adjustable in the settings menu. So I will be connecting it to the audio panel. There is also an audio out from the EIS that sounds an intermittent tone when a warning limit is exceeded. I tested it out but decided that the tone was just too annoying in addition to the flashing big red light. I won’t be attaching the EIS audio out.
