    Auto pilot

    Had anyboby put in a S-Tec 20 Auto Pilot? How much did it cost
    installed?

    I am thinking about putting in a auto pilot and was wondering who has
    had them installed and what they thought of it.

    Auto pilot

    In 2000, I installed and S-Tec 30 which has the same capabilities of
    the 20, but is mounted separately from the turn coordinator. I chose
    the 30 over the 20 because it has the ability to track a back-course
    and the most frequently used approach at my home airport (KTPK) is a
    localizer back course. In 2000, it cost about $5,900, including the
    purchase of a new turn coordinator to drive the unit. IN 2005, I had
    the unit upgraded to the 2-axis S-Tec 50 for another 5 grand.

    Many IFR pilots will tell you that they wouldn't fly IFR without an
    autopilot. Now that I've had one for 5 years, I agree wholeheartedly.
    It makes flying long-cross countries less tiring and, more
    importantly, it's an invaluable asset while your hands and mind are
    occupied with approach plates, etc. For years, I debated about
    whether I wanted to spend $5,000 more for altitude hold when it's not
    that difficult to trim our Musketeers and Sundowners to maintain
    fairly level flight, but it's one of those things that I now wonder
    how I ever got along without.

    As for the particular brand, I've been very happy with S-Tec. The
    rate-based autopilot is an added safety measure in case of vacuum
    failure, too. If can choose to fly the autopilot in "stabilized"
    mode, meaning that it will hold the wings level, or track your VOR
    and/or GPS. If you have a DG with heading bug, you can also fly a
    specific heading. Both the 20 and 30 will track a localizer (as I
    mentioned, the 30 will also track a back-course). If you eventually
    upgrade to the 40 or 50, note that both provide altitude hold only,
    not altitude preselect. Nor will they track a glideslope.

    The only complaint I've had is "wing-walk" in "heading-hold." which
    means that there is occassionally a noticable rocking of the wings
    when the autopilot is following the heading bug on my DG. This has
    been corrected, but tends to need periodic adjustment. I'd recommend
    the yoke-disconnect, which allows you to pop off the autopilot with
    the press of a button on the yoke. My S-tec is connected to both #1
    and #2 VORs and to my GPS. While some of my friends flying faster
    airplanes keep trying to get me to install GPSS roll steering which
    anticipates changes in heading of a GPS course, I don't find a need
    for it at 115 kts. When the autopilot is tracking a GPS course with
    the occassional jog (say, I switch headings because I have chosen to
    go direct to an intersection), there's a little bit of hunting for the
    new heading that would probably be more of an issue if I were
    traveling faster (hence the need for GPS roll steering). All in all,
    I'm very happy with the upgrade.

    I believe you are incorrect about the S-Tec 30 having automatic
    back-course capability. The S-Tec 40, 50, 55, 60 and 65 do have this
    capability. Since you mentioned you changed to a STEC 50 that's probably
    when you picked-up the back-course capabilities. The S-Tec 30's
    advantage over the 20 is the 30 has altitude hold - both the 20 and 30
    use the turn coordinator while the 50 also requires a separate unit.

    The installation of my S-Tec 30 ran about $10,000, which included the
    GPSS that interfaces to my Garmin 430.

    David is right. I confused the model number of my S-Tec. I installed
    the 40 (single axis) then later upgraded to the 50 (dual axis). I
    believe the rest of my response is accurate, though.
