John,
In reference to your question about uneven full flows from the tanks. I
never have flown with the Zenith supplied caps but from the beginning,
after reading about the problems of others, I installed the caps from Wag
Aero. BTW if you don't have a tube bender. go to Harbor Freight , they sell
a cute little one for not much money.which fits the application perfectly
and makes a proper bend. On mine I had to go past ninety degrees to get
the right attitude in relation to the wing. As others have pointed out I
think that this set-up offers a couple of advantages: first, the caps have
never leaked across the wing, Second, they offer an "equal positive"
pressure in the tanks to insure even flow - I don't seem to have the
extreme imbalances discussed by others using the "standard caps". I also
found a rubber "washer" that I glued to the top of the wing to prevent
spilled fuel going inside the wing. After 60 hours I have no complaints -
I find the flows to be about even - especially if I fly straight and level
for most of the flight profile. I might be a "half of a gallon" off after
an hour or so of flight. I think that this is resultant of equal pressure
from the forward facing tubes. Remember, when you add complexity you add a
"small" chance for error. Most of us who have experience in the older
airplanes with left - right - off fuel management systems - think, PA-22,
PA-12 etc have managed to shut down the engine - sometimes at a most
embarrassing moment. Still - because it will be easy - I plan to install
two valves, one at each wing root above my head on the panel that forms the
top of the cockpit just under the Plexiglas.. This would allow ease of
fuel management, if necessary and or an emergency shutoff closer to the
wing.
Still grinnin!

Today I went on a 1 1/2 hour flight up into the mountains with a landing
at the Mariposa, CA airport. I landed back home (Turlock) and went
thru the normal shutdown sequence. When I started to remove my
headphones I found that the gel filled earpads had leaked into and
around my ears. It wasn't just on one side either. Both earpads had
ruptured but because it was warm, I had not noticed the gel was on my
skin until I started to remove the headset. Needless to say, this was a
little startling as it sticks to the skin and stretches.
Has anyone else had this issue with any model headset? My headset is a
Softcom C-200 ANR. There was a spare set of earpads in the original
box so I don't have to buy a new set but it seems like this shouldn't
happen with just normal use.

PS- In retrospect it is kind of funny. Here I was thinking my brains
were leaking out thru my ears.
