• 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.…

  • Fuselage gussets

    Today I spent a couple hours putting the forward fuselage gussets in place. They are unique to the -7 vs the -7A. The tri-gear plane rear landing gear are mounted just forward of the center section. Since the -7 is a tail trager, there is a gap here that need to be reinforced using these…

  • Behind the scenes and Wire Harness

    Over the last two weeks I’ve spent many hours working out how much stuff there is left to do. I put together a list of everything I can think of, adding effort estimates to each item and adding time spent. Google sheets has been awesome to organize my to-do list. I’ve completed about 100 hours…

  • Closed out the wings!

    Today I hit a huge milestone! With the help of my fiancée Britney and my friend Mina, we were able to close out the final skin on the wings. With all that’s going on, I was worried that I wouldn’t make much progress on the project, which has turned out to be somewhat true. But…

  • Vertical Power PPS

    This weekend I had a few hours to work on the plane. It’s been a couple months since I’ve spent a good chunk of time on it. I decided to take off the old conventional master and starter contractors. I’ve decided to go with Vertical Power Primary Power System. This is a single unit that…

  • Heat Muff, Exhaust, and Fuel Tubes

    Today I spent a few hours working on the exhaust hangars, heater and the fuel lines. It’s been on my to-do list for a long long time, but I finally marked and drilled the hole in the firewall for the fuel line. I then test fitted the fuel line between the pump and firewall fitting.…

  • Finished closing out first wing

    This weekend my buddy Norio and I spent about three hours closing out the final wing skin. It was a lot of shuffling and checking rivets after bucking them. Once we got the hang of the pattern, it went quicker. Still required maneuvering my arm through tight spaces and rib lightening holes. Here you can…

  • Wing skins

    Tonight my buddy Norio and I spent a couple hours prepping and riveting the final lower wing skin. After testing the fit, we bag prepping to river the inboard rivets. We started with the lower corner of the rear spar and worked our way across towards the wingtip. After riveting the first rivet we checked…
