To avoid magnetic coupling, Bob Nuckolls recommends separating the “fat” wires from the “skinny” wires (The AeroElectric Connection, Chapter 16). The fattest wire penetrating the firewall o ...

Has anyone drilled a hole in the forward wall of the right side gear tower in line with the firewall hole shown in OP-35 to route the power wire from the firewall-mounted battery into the avionics b ...

Next question. I am looking at potential ADSB-In antenna locations. My comm. antenna will be just aft of the front spar on the left side with the X-ponder antenna just forward of the F-807 bulkhea ...

Back at it after a long layoff. Working on electrical/avionics and I am in way over my head. Bear with me-I expect this will be the first of many posts.
Planned system for day/night VFR is VP-X ...

I am looking for a DG, not for my –8 project, but for my t/d Colt that is helping me keep the rust off while I am building. Would prefer the old AN style as that is what went belly up. Replacing ...

Any pictures of Skyview installations available? I’m in the process of locating components (with mock-ups) and looking at wire routing options. Especially interested in the EMS sensor cables rou ...

Thanks to all for the feedback regarding sources for the subject hardware. Guess I should not be so quick to grab the ACS catalog when a trip to Home Depot or Lowes works just as well or better. A ...

Dynon, and I am sure all other manufacturers, specify non-magnetic attach hardware. I am thinking AN3C bolts with MS 21044 locknuts, but not sure if these are truly non-magnetic. Some stainless is ...

Responses to my comm. radio installation question opened up a new path. As a result (thanks, Robin), I am now looking at a dual Garmin GTR 200 installation on the upper left side of the panel. Ho ...

A personal preference issue: On my instrument panel layout, I have been showing a SL-40 located on the vertical centerline below a Dynon D1000 display, however, a trial fit of a mock-up at this loc ...

Now that I am seriously looking at what will be required to install the Matco parking brake unit and route an actuator cable, I am wondering if it is worth the time and effort. Pros and cons?

After many hours and several feet of scrap, I am finished bending fuel lines and moving on to brake lines. Wondering if flex hoses would be a viable option to the hard lines inside the fuselage. I ...

I am looking for advice on the best way to bend this line. The instructions are not very helpful. At least I have only one line through the gear tower to bend as I am going with a carbureted engin ...

Seems to me the fuel vent line design leaves a lot to be desired when it comes to installation and maintenance. In researching problems/solutions with these, I came across references to the coiled ...

I would like some feedback on this subject as it is one of the loose ends in planning my electrical system. I have settled on AeroLED for the position lights/strobes, but am having difficulty sorti ...

Are there any RV8 builders within a 100 mile or so radius of Grants Pass, OR? I’m at a stage where it would be helpful if I could look at other projects and exchange info with other builders in a ...

I’ve cut out each gear tower lower web in my QB fuselage and plan to install 0.063 thick covers, but a bit different from what I have seen. I am curious as to whether anyone else has done this an ...

Are there any guidelines I can use to size doubler panels for the antenna installations? Can’t find anything in AC43-13 except standard rivet spacing. For the bent-whip comm antenna, I have chos ...

Has anyone installed automotive-style vents for fresh air and/or heat? If so, I’d like feedback on what kind and source. I think they would be a functional improvement over the standard eyeball v ...

I’m looking for feedback on adding wire routing holes to F-806B and F-807A. Specifically, I could use an additional set on the right side so that I can route the transponder antenna cable under th ...
