    Worth consideration for Phase 1 Testing

    I don't know if this is a Regional Thing, but the San Francisco FSDO will NOT approve a Phase 1 testing area with a Class B, C, OR (and this is what I didn't know) D airspace at the center. So no towered airports as your home base for your testing. I'm not sure how long this has been policy...

    Garmin Data Link configuration

    Has anyone that isn't a dealer gotten the downloaded configuration tool to work? You connect to the unit with a USB-B cable and you can, in theory at least, twiddle settings like your N-number. I can't get it to work. I have a query in to Garmin, but I wondered what the Hive Mind knows...

    Pitot static plumbing

    I had a professional come and do my pitot-static/Mode C checks today, and we had to chase leaks at the Dynon Air Data unit. He says this is not uncommon on Experimentals that use the push to connect fittings for plastic tubing, and he greatly prefers the Nylo-Seal stuff. As it turns out, my...

    Current Sensing for an Alternator-Dependent airplane

    Now that I have two electronic ignitions, and NO self-generating magneto-like ignitions on my Aerovee Sonex, I'm a little concerned about my SINGLE 20 amp permanent magnet alternator (we will argue some other time about whether this was a good idea, I had my reasons, but I DO NOT advocate...

    Chuggers-alt Group Bob Hoover files?

    R.S. "Bob" Hoover, aka Veeduber, has been dead over a decade, and I still miss him. I'm trying to collect all the files from the old Yahoo Groups Chuggers-alt Group that disappeared when Yahoo killed that business line. I've got a few of the original DeltaCad source files, and I have several...

    "Surfboard" wings with carbon rod spars?

    Would this work? Build a Rutan style "surfboard" wing with hot wired solid cores but use "graphlite" pultruded rods instead of flagged Uni for the spars?

    Don't do this

    Aluminum road signs get hit and mangled regularly in my region, and there is a temptation to grab a chunk of whatever tiny bit remains flat, chopping it out of the wreckage with a cordless jigsaw, as it's at least .080 thick, of a very corrosion resistant 5000 series alloy, but you're depriving...

    A Fellow Traveler in Bad Life Choices

    http://www.youtube.com/@benbeames First, he built his own Lotus Indy Car "tribute". Then, he built a GT-40 replica that is lighter than the originals by a lot. With little money, and few tools, starting in a dog run side yard at a beach house in Santa Cruz. He seems like a genuinely nice guy...

    Earbuds with Headsets

    This looks like a really good idea DCH pdf | cep-usa Comparable levels of noise reduction to ANR without the complications. Has anyone "homebuilt" a similar solution? It looks like the kits from CEP are over $200. I wonder if a set of $25 earplug earbuds and some parts from Digi-Key would do...

    Powering an electronic ignition

    Should the coil pack be "always on", powered from the hot lead of the battery ahead of the master solenoid, OR on whenever the master is on (no switch), OR on it's own switch downstream of the master, OR on it's own switch upstream of the master? The control box gets switched, for sure. This...

    Curtis Fuel Drain Valve O-Ring size?

    They say they are not overhaul worthy, and I bought a new one, but really? How hard could it be to put a new O-ring on one? Anyone know the size? This is for a 1/8" NPT in a gascolator.

    Has anyone heard tell of an L.D. Brown near Needles, CA? P-38 replica

    According to William Wynne, the Corvair Guy, about 20 years ago he was just about done with a "a perfect 66% scale P-38 Lighting, powered by two Corvairs." "The quality of the work was astounding, he had first built plugs, then hard molds, and only then bagged parts out of the molds. The...

    Flat wrap sheet metal wheel pants?

    Leeon Davis, Morry Hummel, Steve Wittman built and used them, but I can't find decent pictures or drawings or "How To" information. I have ideas, but I'd like to make use of "Prior Art".

    CB Performance bolt together rocker shaft kits

    ...the shafts come with the circumferential grooves Veeduber (R.S.Hoover) advocated to increase oil flow to the valve train. http://bobhooversblog.blogspot.com/2007/05/hvx-mods.html The associated shim kit had enough shims to allow me to get the spacing and clearances I wanted. With the...

    Parts For Sale V-Twin Engine Development Project in NoCal for little or no money

    Deep in the early part of the pandemic, I was bored, and so I started a project to mess around with an industrial V-twin. Subsequent to that, I bought a 98% complete Sonex that is sucking up all my free money and time, so progress on the V-Twin is stalled. Here's what I've got: An assembled...
