[n85ae]

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.
