if I bend the bottom tube of the Zenith probe down 45 Deg and use another static
vent source from the fuse sides then it should work if connected to a Dynon?

Hi Chris,
I have a Lift Reserve Indicator (LRI) I built while waiting for one of
my sub-kits to arrive. It seems to work in a similar fashion to the
Dynon AOA. It uses a metal divider to choose which of two input ports
gets the larger amount of air pressure - depending on the attitude of
the airplane. Rather than having one direct pitot tube and one at a 45
degree angle it has one input pointed up and another pointed down.
I mentioned all that to allow me to point out that the idea works just
fine but the actual implementation needs to be adjusted and calibrated
to be useful in flight. I have an analog gauge that shows the
differential pressure. Dynon just shows a few points of data which
(presumably) show similar information. You might need to tweak the
angle of the second pressure input tube to get a reading on the Dynon
that is useful.

Sam Buchanan successfully used a different pressure source for the Dynon AOA indicator:

How to build your own is described here, ( I think this is the one Paul is referring
to):

It seems a similar probe with only the lower port, mounted at an appropriate location,
should work with the Dynon.

I am installing a forward hinge canopy on my 601 HDS. Zenith sent the
side covers 6C3-6/1 which are larger than the original version and also
curved which the drawings don=99t address. If anyone has some
close up pictures of their installation please send them to me.
Thanks,
Steve Sims
