The
pitot tube bracket I ordered from Aircraft Spruce arrived today.
I ordered the Chrome finish for my pitot tube bracket. I am
frequently amazed when building this airplane. A number of
parts I have ordered are wrapped in kleenex or paper towels and
placed in a zip-lock sandwich bag. It is as if these parts
are made by out of the garage or a basement of some individuals
home.
I
unwrapped the Gretz Aero pitot bracket from its high tech paper
towel packaging and it looks GREAT!!! The pitot mounting holes
even line up with the pitot (had to make sure I didn't screw up
when I ordered). Since my wings are far from ready to talk
about pitot tubes, I wrapped it back up in the paper towel it came
in and put it in a clearly labeled divider drawer.

Also arriving
today via UPS, was my heated pitot tube from Chief Aircraft.

I contemplated whether
or not to go with a heated static source and then finally opted
for the standard, run of the mill heated pitot WITHOUT a heated
static source. I looked at other builders web sites and referred
to information from Gretz Aero on the advantages of the two types
of pitot tubes http://www.gretzaero.com.
The pitot tube with a heated static source looks like the one below.
Notice the two tubing fittings and the longer snout. This
model does not have a constant resistance heater (larger current
in-rush at turn on). Gretz Aero states that this pitot tube, in
combination with his mounting bracket, is slightly more accurate
than the PH502-12CR pitot tube (without heated static). When
I went out and looked at other builders web sites, I found at least
one builder who didn't like this pitot tube as he found it to be
very inaccurate. He ended up removing this pitot tube and
putting in the PH502-12CR.

Take this information with a
grain of salt. Many builders web sites I looked at did not
going into any great detail on advantages and disadvantages of the
two types of pitot tubes. I figure that there are several
variables contributing to the accuracy of the pitot tubes that I
could not verify the installation of others while researching
this from my computer in the basement.
I like the
pitot tube from Aero Instruments shown below. It has a constant
resistance heater (PH502-12CR) as indicated by the CR at the end
of the part number. The constant resistance heater means that
it will draw the same current at turn on as it will when it comes
up to temperature. The fit and finish of this pitot tube is
EXCELLENT... The only thing I found wrong with it is Aero
Instruments misspelling of ELECTRICAL on the box :)

I debated
on my timing for ordering the heated pitot tube as it was fairly
expensive and I was at least 5 months from needing it. I looked
on Aircraft Spruce's web site a couple of months after I received
this pitot and prices on these have more than doubled in the last
3 months. I paid $415 (which I thought was expensive) and
within 3 months, they are selling for $995. That is ridiculous!!!
In hindsight, my timing for ordering the pitot was great!!!
I got a great deal by comparison.
