    N85AE Now has a Uavionix EchoUAT and SkyFYX-EXT installed in the pilot side
    wingtip.

    Like Bruce, first test flight had some red flags, which turned out to be the
    transponder threshold adjustment needing to be adjusted. Uavionix replied to
    my email for support on a Sunday morning after I emailed on Saturday night
    and by noon Sunday I was able to complete another test flight and it was
    completely clean.

    The threshold adjust is done from the app you set it up with, they have an
    advanced settings page which is accessible fairly easily. There is a doc on
    their website which details using it. Essentially you just sit in the plane, and
    see if your transponder light is flashing (indicating it's being hit by radar) and
    you adjust the threshold a little bit at a time until you see the app indicating
    pressure altitude. After which it should be close if not completely set.

    I took the supplied antenna and rather than create a ground plane, I modified
    it as the below image indicates with some copper wire (The four radials are
    inside the wingtip and the antenna protrudes from the bottom). I've had no
    issues with reception, and my test results were clean.

    Should be interesting to see how the Garmin lawsuit against uAvionix shakes out.

    I just saw that, too. How disappointing.

    I can take a look, I think I have some. Honestly the EchoUAT is about the size
    of a deck of cards and I just screwed it to the end rib. The GPS is mounted with
    a bracket I made which looks like Bruce Lina's GPS mount. The antenna simply
    sticks out of the bottom of the wingtip. Currently I have copper tape strips as
    a ground plane in the floor of the tip, but can't tell any difference over the first
    antenna (the spider). There's a ton of room in the wingtip so it's a very simple
    install.

    I'll post pics if I find some.

    Regards,

    Uavionics works with both modes C and S according to their website.
