SOLD – Navaid Wing Leveler

Some Documents I gathered:

Removed as part of move to iEFIS autopilot:

Navaid Wing Leveler head
Navaid roll servo


Here is a better face shot. Looks like rate of turn is adjustable and the bar graph at the top indicates against a set of markers.






I finally got around to removing the servo, which was under the passenger seat. It looks like the original installer modified the removable cover slightly. I’m assuming that was to make it fit in a tight area as the remove ‘notch’ is right in alignment with the seat support rib.



The internals were not affected & seem OK, it was working when last used. I can set up & test on the bench & take video if you want.


I found the original wiring harness, which will come with the package.

    Hi, Bill,
    Following you on the MGL forum. Thanks for all you’re doing there. I hope someday, when the time comes, to have MGL for my EFIS. Not there yet.
    Question on the Navaid wing-leveler: Does it have an indication of bank (or turn) on the display? I’m looking for a wing leveler that can be used as a back-up “turn & bank”. Will the Navaid unit do this?

    Hi Jim,
    I’m pretty sure it just has the bubble indicator; but your asking reminded me that I have more documentation on it:

    I’ll add that to the page (if I can).

    I take back what I said. I found & uploaded the manual. It looks like it has a marker type display for standard rate of turn, etc.

    Hi, Bill,
    Thanks for making the documents available on the listing. From the looks of the manual, it does give a turn indication, which is what I’m wanting. Further questions: 1. Does it use a rotating gyro or MEMS? 2. What will you take for the system (head and servo)?

  5. 5 On May 30th, 2013, Bill said:

    I am pretty sure it is pre-MEMs and is a mechanical gyro (but not absolutely). I have seen these older systems selling in the hundreds of dollars, so how about $300 plus shipping. Much lower than that I’ll just keep it for a spare wing leveler.

    Hi, Bill,

    How about $300 and you ship it? Cheapest way, of course. I’m not in any hurry. Alternatively, if we could meet somewhere, that could work. Where are you located? I’m in Augusta, GA. I have a cousin who spends his winters in Mesa, AZ. Is that near you?

    Hi, Bill,

    One further question. Does the gyro require a vacuum connection, or is it electrical?

    No vacuum, it is electrical. Still thinking about the offer.

    What do you estimate the shipping to run?

    Is your offer of May 30 (5 above) still good? I’ll pay $300 and shipping.
