Bryon,
With quick calculation on my TI calculator, I guestimate that with 1/32" too
low on the mounted attach angle will result in about 0.138 degrees
difference in your angle of incidence. I estimated/measured from the attach
angle to the rear of the HS to get approx. 13". A 1/32" drop over 13" run
amounts to about a 0.138 degrees decrease in your angle of incidence. I am
not an engineer, so I don't know if this matters, but I do figure that if it
does, then this will likely be the least of my worries while working my way
to a finished RV-9A. 1/32" is about the thickness of the pen marking line on
the attach angle isn't it? Hope this helps.
Comments from others builders and engineers are requested and welcome.

When I ordered my avionics from Van's I asked about this antenna. The reply
was, in so many words, that it did work but was not nearly as effective as a
good whip.

On my Lyc 150 HP I am using the prop Vans recommends - Sensenich 77" pitch
with the metal spinner that Sensenich sells. Initially, without the wheel
pants and leg fairings I could not get the prop up to redline (2600 rpm) in
level flight. After I put the fairings and pants on it will redline in level
flight after a few minutes but just barely. This makes it a good choice for
a cruise prop and climb performance is just fine. Top speed is 160kts but
since it also burns over 9gph I have been trying to fly around at 2300 to
see how that works. Speed is about 135kts and fuel burn is closer to 8 or
maybe even a little less. If you put a little work into the metal spinner it
will polish up and look very nice.
BTW: since the 9A sits about level on the ground as opposed to the 6A which
is somewhat tail low, getting onto the wing without the step would be rather
difficult-especially for us old guys.

Van's has confirmed this is NO problem. Being that the horizontal is attached
to the fuse with shims, you would simply adjust the thickness of your shims
as needed.
Looks like I was concerned over nothing.
Thanks to all that responded.

Hi All,
Just a quick note to let you all know that I "FINALLY" got all the
components together for the Dynon EFIS install kit's I promised awhile ago.
They include connectors, crimper, pins, etc..
Price is $55.00
