Wow, what rapid responses!

In my talks with the boss at PSS, I discussed the glider/short wings
conundrum.
One needs to add a second EPROM when the wings swap, since the airfoil
is different.  If we didn't have flaps, that could have been the easy
switch.
Nevertheless, it should be possible to piggyback a small circuit board with
an electronic switch onto the original EPROM socket that would be
microswitched to an appropriate tang on the wing root.

PSS is also in the process of certificating the AOA sport, so the product
development is officially "mature", i.e., finished.  There were some
comments
---From some of my RV friends about the display or warnings being underdamped,
which PSS claims has been solved within the last year with V.7 of the
software.

Some of you have been irritated that PSS didn't partner with BlueMnt to
put the AOA indicator on-screen.  Aside from there being little incentive
for them to do that, on-panel is the wrong place for an AOA.  It needs to
be in the pilot's field of view as s/he looks out of the window during
landing, which is why you see so many AOA-sports sitting on top of the
glareshield.

Continue!
