    Does anyone have a recommendation for a shop in or around Texas that could help me with
    overhauling an Lycoming IO-320? I'd like to do most of the actual disassembly / assembly myself
    so I'm looking f...

    Congratulations Hardegg. I'm thinking of using Four Winds for my Pitts transition training
    sometime in the not-to-distant future. Let us know what your experiences are and welcome to the

    Very sad and a little bit too close to home.My brother watched it happen. Busy pattern, setting
    sun, no radio in the Luscombe, hiigh wing climbing into the low wing. My sister-in-law is a bit
    freaked ...

    That makes sense, and that relay does the switching. Any idea what the capacitor does between
    the relay and the voltage regulator?The capacitor is there as a noise filter as well as kind of
    an energy ...

    I think that a lot of airplanes have switches that turn off the alternator before they turn off
    the master/battery contactor. It's probably a moot point with the SD-8, and I realize that I'm
    picking n...

    I don't think your battery contactor wiring is going to work. Typically the (+) side of the
    contactor solenoid is connected internally and you ground the coil to energize the solenoid.
    There are two p...

    I used a toggle switch for starting in my RV-7. I love it. Will do it for the Pitts as well.
    The hard part is finding one that matches the rest of the switches. I think I found mine at
    Newark Electron...

    Life has been kicking me in the teeth lately. Finally got around to sticking an inspection
    camera in the wings. Everything looks pretty good to me. I don't know that much about wood but
    it's not rotti...

    I've had a battery tender like this one... into my PC680 for 10 years. I'm on my second
    battery but I really didn't need to change the first one I just do because electricity is
    pretty important in m...

    I don't think that you can set the RPM. The SD-8 is a permanent magnet alternator. It will
    generate higher voltages at higher RPM. The voltage regulator will need a certain voltage above
    the set-point...
