“I’d have to pin his head to the panel.”

One of my favorite lines from The Road Warrior, or Mad Max 2, as everybody but us yankees calls it. To paraphrase a little green guy with a mean spin kick, “always in motion, is the panel.” When I started this adventure, I knew I wanted glass instead of steam. I’m a visual effects dork, I grew up on MFD’s and synthetic vision in movies, like the display in Snake’s glider in Escape from New York, or in the dropship in ‘Aliens,’ both of which were done by painting the edges of foam core terrain slices with fluorescent paint and filming them under blacklight to make them look like computer images. There’s also the HITS in Bladerunner, which is pretty much the only way I’d trust the average Angeleno driver in my airspace, even in 2019. That’s only 10 years from now, by the way. Fast forward to present and there’s a tall stack of options to choose from; BMA, Dynon, MGL, Grand Rapids, Tru-Trak, the list is long and distinguished. At first I was all about the EFIS-One from Blue Mountain Avionics. It was my first synVis option.. The Dynon was a good replacement for the steam gauges, but the BMA had some eye-popping features and seemed like a better option to me. At least it seemed like a better option to the ‘me’ in the alternate universe where I have unlimited amounts of money. 14k, ouch. The Grand Rapids stuff is cool, but also expensive, and the screen’s not big enough. If this is going to be my main info feed for flight ops, I don’t want to squint at it. So along comes MGL. The Enigma was intriguing, but it wasn’t big enough, and I was about to blow it off entirely, except for the price point, which is great for what the unit does. Then MGL came out with their Odyssey. 10.4″ of daylight-readable synthetic-vision, programmable-screen goodness. And the price is defiinitely right. for about 6k, I get synthetic terrain, HITS, moving map, WAAS/RAIM GPS, engine monitoring, all the probes and sensors necessary, and it talks to the Garmin SL30 for radio NAV ops. Not only that, it drives Trio autopilot servos. MGL also has their own COMM, which fits in a standard 3.5″ instrument hole, and communicates with the EFIS via proprietary link over a nice tidy CAT5 cable. They are supposed to be releasing a NAV radio companion to this unit, which is fully SL30 compatible. Oh, and it talks to the ZAON PCAS products as well, and it won’t be long before it will display traffic threats in the synVis.
Daydreaming about this is fine, and the whole “what if your fancy gear packs up at night in IMC” question is answered this way: I’ll be flying day-VFR most of the time. Like 99% of the time. I will probably put a second EFIS in there, probably a secondhand Dynon D10 just in case the Odyssey goes south, but I expect it to function as designed just shy of all the time. I would like to get my IFR ticket in this aircraft, and at that point, I will install TSO’d equipment as required. Until that time, I’m going to be quite content with the current mission of regional cross-country VFR and local hops. How hard is it to get to wine country from SMO anyway? Not very.

All my tubes and wires, careful notes…

2 hours.
I suppose I knew better than buying a tubing bender on ebay for twelve bucks and a flaring tool for about fifteen. The tubing bender gouges the hell out of the tubing, and the flare tool die scores the tubing where it grips. So let’s see: Stress risers in aluminum tubing, check. High pressure fuel, check. Inside the cabin, check. Near electrical devices, check. Boo. Hiss. Ordered the Imperial 3-size tubing bender and the nice rol-air (not the $600 one) tool off Spruce this morning.. dammit.. that’s what I forgot. the spring tubing bender. Maybe I can live without it. We’ll see.
Anyway, I got some extra tubing, and went back out to begin the process of mounting the vertical stabilizer. Not sure if I mentioned it before, but the two main longerons and the aft deck stuck out past F-712 about 1/16″, enough to keep the VS from laying flat on F-712. This morning I filed down the offending metal and cut off the 5/8″ from the forward spar to make it friendly with the F-781 mount plate. I drilled the mount plate to the HS forward spar and bolted it in, temporarily. This is where it sits until I can get the VS aligned to vertical and drill the holes in the VS/F-712 sandwich. I need to get this done so I can make the elevator push tube and elevator stops constructed. At that point, I’ll do the control column, and once I’m convinced that rigging the aircraft is actually possible, i’ll put the emp back in the attic until final assembly. I’m also rapidly approaching the singularity point of painting the interior. Before this happens, I should probably figure out what I’m going to do about autopilot servos. I haven’t closed the wings yet either, which is also relevant for that issue, so there’s going to be a prying open of the wallet in the near future. I’m saving that for later, when I know for a fact that all the wiring has been run and won’t need anything new for a long long time.
