  • More Avionics Wiring

    Today I spent a solid chunk of time routing wires. Making wiring harnesses has been one of my the more satisfying parts of the project so far. I started by organizing the firewall forward sensor wires. This bundle contains everything from engine temps, to oil and fuel pressure and the ignition harnesses. These are now…

  • Ignition Harnesses

    Tonight I spent a few hours making my ignition harnesses. My engine uses twin P-Mag ignitions, so I had to make two identical harness. I started by removing the connectors on the ignitions so I can attach the wires. The connectors use a screw-clamp style connection. Here you can see the connector attached to the…

  • Engine Controls Bracket

    Yesterday I spent a few hours making the engine controls bracket. The bracket that comes in the kit is flimsy 0.032 aluminum sheet that is bent so it can attach to the bottom of the panel. I knew I wanted to use something different than the stock bracket, so I made one. Here you can…

  • VPX Wiring #2

    Today I continued with my wiring extravaganza. I didn’t get any new pictures, but I started by beeping out the ELT DIN connector. I originally made the harness a few years ago, and forgot to write down the wire designations. I tested the connector and verified with the specs provided with the ELT and then…

  • Fuselage Wiring

    Today I did a lot of wire organizing in the forward section of the fuselage, under the panel. All of the cables routed from the aft fuselage and under the seats funnels into the center section and routes on the floor up to the panel. Once I organized the rats nest of wires I ended…

  • VPX Installation

    Yesterday I spent most of the day at the hangar cleaning up and working on the installation of the VPX mounting brackets. I started with the rough position of the mounting brackets under the sub panel ribs. This will be the final position of the VPX under the panel. Each corner needed a nut plate…

  • VPX Wiring

    Today I spent a few hours working on the main power harnesses. Since I’m using the Vertical Power VPX, all the power wires connect to a central distribution point including the panel switches. It’s all very straightforward once you have the pins all planned out. Here’s the VPX mounted under the panel (it’s all upside…

  • EMS wiring

    This weekend I spent time working on the main EMS wiring harness. It includes everything for engine monitoring including oil pressure, temperature, fuel flow, fuel pressure, manifold pressure, rpm, etc. It’s quiet extensive. I started by reviewing my wiring diagram that I made, and reviewed the pin out of the EMS D37 connector. I then…

  • Roll Trim System

    This weekend I spent a few hours working on the roll trim system. I’m using the Ray Allen trim system from Vans, so everything is nicely packaged together into its own subsystem. I started out by modifying the plastic block that holds the pivot arm. This needed two holes drilled through it foe the AN3…

  • Wing tank brackets

    This weekend I spent a few hours working on the plane. I wanted to get some specific things done in order to make a little progress towards fitting the wings. I spent the day installing the fuel tank attach bracket to the outside of the fuselage. This required fabricating the internal support bracket and spacers.…
