I have one in my newly acquired Ka-8, and one in my
spares drawer. Sorry, but it is going to go to one
of my clubs ships sometime soon.

RICO also made a stand-alone like the PIEP. You might
see if he has any left. Probably doesn't , but it
would be worth a call or e-mail. And I have plans
for one from the 1960s. If you like, I can send you
the article. This one was developed by the Akaflieg
Stuttgart, so it must be good! I know it worked well,
as I flew with one of these and a Winter in a long
winged Cherokee (The Annebula, pictured in the most
recent sailplane directory as the Cherokee picture).
Got my Diamond Goal/Gold Distance in that ship. Ah,
the fun of those days! If you find someone that is
an old hand to electronics, he can probably design
you a circuit to do the same thing that our homebuilt
ones did.
