| Subject: | Current crop of pitot tubes |
Hi all. I'm working on an RV-10 and am at the point now of
considering what kind of pitot tube to put in the thing. The bent
aluminum tube idea, though functional, doesn't really appeal to me.
Though I'm not an IFR pilot at the moment, I don't intend to remain
that way indefinitely, and I'd like to future-proof the plane as much
as practical. So I'm looking at putting in a heated pitot. Up until
now I've been assuming I'd go with a Gretz pitot - I like the idea of
its internal temperature regulation rather than just running at
maximum current draw the whole time it's on. But of course now that
I'm actually ready to get one it appears as though they're not
currently being manufactured and I haven't found anywhere that has
them in stock.
So what other options could anyone out there suggest?
Thanks!
Dan

| Subject: | Current crop of pitot tubes |
I just purchased one from Aircraft Spruce a couple weeks ago, but they
appear to be out now.
This was posted on the Gretz site:
NOTICE: Gretz Aero, LLC, has been forced to stop production of this
wonderful product, the GA-1000. The reasons are two-fold. First, I cannot
keep up with the current demand for the GA-1000 and second, the company that
has been providing the composite molding material has drastically raised
their prices and minimum order requirements. I have found another company
who can provide the same molding material at a reduced cost and lower
minimum order quantities. However, at this point I feel the time has come
for me to cut back on my current Gretz Aero workload. I enjoy developing
new aviation products. Selling this part of my business would allow me the
time to bring some of my ideas into product. I fully expect to continue with
the mounting bracket part of the business. If anyone is interested in
purchasing the GA-1000 and GA-500 part of my business, I would be willing to
negotiate. I can be reached at 208-834-2312 or 208-863-7045.
This is too bad. This was a great product.

| Subject: | Wiggly Cotter pins |
I find wiggly cotter pins a lot doing EAA Tech Inspections. There is no
standard on experimentals, the owner/builder sets the standard. The
AC43-13 wants them tight. The airliners you fly on are all tight. The
airline Quality Control Inspector will fail any that are wiggly. We do
that by pulling the head down into the fastener, bending the legs
against the object and often smacking them with the handle of our
pliers. QC always looks for wigglies, correct leg length of cotter pins,
correct hardware lash up and often on critical items like engine mounts
and landing gear confirm NO Wigglies by using torque seal paint.
I always point out the wiggly ones on engine mounts.
Guess I must be an AR Tech.

The chrome Gretz mount with the Dynon heated pitot or Dynon's heated
pitot with angle-of-attack looks very nice...and works great.

Does anyone know if the Dynon pitot with angle-of-attack would connect
to/work with an AOA Sport? I'd love to avoid drilling any holes in my QB
wings ..

It would help to provide a website. However, I personally would never
use a geared engine. It has to run at a very high RPM and may have
significant operational issues.
I would not buy a plane with such an engine so if that sentiment is
widespread
you would pay dearly if you ever decide to sell or your market would be
very small.

Ron, all Rotax aircraft engines are geared to the prop. They have been
running successfully for over 20 years and virtually all LSA planes are
using the Rotax 912 "geared" engine.........even Van's RV12. What
"operational issues" do you refer to?

You need to match the pressure source (i.e. the holes, either on the
pitot tube, or the wing) to the sensor. So, if you want the Dynon
pitot, then you need to use their EFIS to calculate the AOA. If you
want the AOA Sport system, you need to put the holes where they tell
you to.
This is not a plug and play system, where you can mix and match
pressure source and sensor, as there are no agreed upon standards for
the pressure source.

Hi Mark,
For any product that life/limb/safety depends on I'd ask the following
questions:
1) What are the performance numbers when installed on the airplane you are
selling/marketing it for - and I'm talking REAL WORLD performance/flight
numbers. Not "calculated" type numbers?
2) How many hours are on your test RV-10 or any aircraft for that matter
(since you're selling and engine package for an RV-10 it must have at least
been test flown)?
3) Is your company capitolized enough to handle liability insurance,
warranty, etc..
4) How many have been sold, installed and flying on the airframe that you
are marketing it for?
5) What are the approzimate total fleet hours for your engine?
6) Are the funds/deposits held in escrow in case of a refund or used to fund
the ongoing business....if no escrow is the business funded off of peoples
deposits?
I don't mean to sound negative because I think Mr.Warren is a brilliant
engineer. That being said, I really get leery about companies marketing
stuff for airframes which they've done little to no flight testing on.
Next, having been burnt for many thousands of $$'s over the years by well
intentioned and also good engineers, I want to see what kind of financial
health the company is in....especially when someone is charging 10's of
thousands of $$'s for a product and company that literally have zero
history. There have been a lot of alternative engine designers selling the
next panacea of products...some very well funded and some not so well
funded. Note Thielert just went bankrupt in the past day or two and I'm
sure with their many millions they too thought they were capitolized well
enough......
I do wish him well and like to see people developing alternative products,
but as I said before I get really nervous when people are already selling
something specifically that has never flown. Perhaps I sound negative and
that's not my intention. Those are just serious questions I'd ask any
supplier...be it props, engines, PSRU's , fuel injection systems, ignitions,
etc..
My 2 cents as usual!
Cheers,
Stein
