Many thanks to everyone who responded to my request for information on
static ports.
Now all I have to do is persuade the PFA (I'm in the UK) to allow me to make
the changes!

Frank: > "It's tough finding a laptop with a serial port anymore!"
Craig: >"Have you tried a USB-to-serial adapter to give your newish laptop a
serial
port? Any CompUSA (or maybe Radio Shack) should have one."
Craig, thanks for the suggestion. AMD provided the USB/Serial adapter and
brought it out as a USB plug in the panel right under the Dynon. (You can
just make it out in the movie on my blog) That's a good idea for any builder
using any glass panel system.
My rub is in getting the Dynon update software, very nice but monolithic and
not flexible, to recognize the USB-serial driver as a valid port. Been
through two "kits" (both Chinese manf: "sun flower moon" etc.) with various
revisions of their USB-serial drivers. After much research I believe I
would have to change the laptop OS to Windows XP and that would be a
hassle! Then, there were USB cable connector issues I have not bothered to
master. I let the folks at AMD, who do it a several times a month, update
me.
If you get the OS and drivers right and the serial cable right, then
updating from the laptop's USB port to the Dynon's serial port is a piece of
cake. A hands-off no-brainer. Do it once (keep the same laptop and cable)
and you'll always be able to do it. But, the first time can be a
challenge.

Well, Gig, I never suggested that it was critical. And, you're right--it's
not. But, I've already got the gage, I think I have the space on the panel,
so, I think I'll do it, just because it is nice.
I also plan to put in an analog altimeter and air speed indicator, even
though the Dynon or GRT EFIS provide the same data. If I was a very
experienced pilot, or even a really good "natural" pilot, I probably
wouldn't bother. But I'm planning on getting from ~160 hrs to a life time
of flying in my little 601, and I'll be more comfortable seeing those
familiar analog gages on the panel. And, I know they'll still be working if
the electronics die for whatever reason. If I had infinite funds, I'd
probably put in a duplicate EFIS with some sort of backup power supply.
But, for me, I think the analog gages will provide an adequate, and
affordable, comfort factor. It makes sense to me. I trust you'll put in
whatever makes sense to you.

Thank you for the input on the Dynon AOA. I would love to hear if others
have had a problem with the Dynon AOA as you describe. I may decide to
scrap the AOA pitot and just go with the more conventional LRI gage.
Regarding your perceived need for a backup AI, is that because you are not
satisfied with the Dynon AI, or just your desire to have a backup?
I am looking at the TruTrak ADI autopilot, which had a combination AI-turn
coordinator display. For a bit more than a simple autopilot, it would
provide a backup AI. Is anyone out there using the ADI Pilot I or II? How
has it performed?

Ken
Have you installed the Dynon in your aircraft and/or are you aware of
other's who have applied Dynon's fix? How has the AOA performed after the
fix? If the location of the pitot is critical, is there guidance available
about where to install it on a 601XL? Unfortunately, the location is not
something that can easily be changed after the initial installation, and a
series of trial and error installations would make a mess of a wing. There
is a school of thought that suggests that AOA or LRI is not necessary for
"real" pilots. And then there are those of us who would like to have more
info if it would make us safer. I would really like to have that info, but
I would not want to go with the Dynon AOA if it does not provide useful
information.

Or just a response to market pressure ?.Anybody knows about the ulm version?.
I weight 126 and at 42 I don't think I gona get any heavier .I made all questions

Hi All,
I've sent an email to grove asking this question but havent heard yet so
I thought I would ask here.
I've got a 601XL QB kit and the way the brake mechanisms are installed I
would like to swap the Bleed fitting with the 90 degree one so the brake
line will route better.
Anyone see any problem with swapping those fittings ?
Thanks,

On our way home from Las Vegas a few weeks ago, the wife was looking out the window
of our Zodiac and said "Maybe our next airplane should be a high wing."
So now that the wife insists on a new airplane , I've decided to list our Zodiac
HD on Barnstormers and build/buy something new. Oh the things I have to do
to please that woman ;)

I bought the Aircraft Spruce ACS gascolator and the Mount for it. I'm fitting it
to my firewall now. Looking in the catalogue I just noticed NOT FOR USE WITH
AUTO FUEL. Surely they jest. The gasket is Buna N which has pretty good fuel
resistance. How can it be okay for aviation fuel but not auto? Are we talking
additives here? Alcohol, Gasohol, Fructose syrup and such? Comments appreciated.

| Subject: | 701-460 empty weigt |
There is about 24 changes in the 701SP version over the older 960 gross
version. However I am converting a older 701 (serial 1400 something) now
and I can tell you that I have found several hundred changes from the
old plane to the new one. Parts added and almost all parts changed in
thickness.
I would personally order a new kit and register it at 960 gross with the
582. The 701SP version will fly just as nice on the 582 as the older
version. Plus with all the advances in the kit it will be a whole lot
easier to build.
Personally I would never convert an older 701 to a 701SP version again.
I believe it would be faster to make a new one then to re-build an older
version.

Sounds like the static port hose is loose or broken. This will cause a increase
in airspeed indication. Seen it happen more then once.

I've had an ACS Gascolator feeding auto fuel 87-octane for 2 years now
and don't see any difficulty with it yet.
Unless they've changed the gasket/packing/o-ring material.

Hello Group ,I have just finished drilling my top rear wing skin .The
top skin specifies 102mm to #RR1 ,the bottom skin does not specify this
distance .I would assume it is also 102mm to #RR1 . Could someone check
the factory supplied skins and determine if this is correct .I am using
plans Dated 03/06 page 6-W-8 . Thanks

Wade,
Both ends of both the top and bottom skins will be trimmed. Refer to the tables
on 6-W-9. You can see that, on either rear skin, there is no wing root trim
coordinate greater than 80mm. And since both rear skins are the same length,
uncut, I think it is safe to assume the 102mm from RR#1 for both. I have no
idea why 102mm, not 100 or 105, except that 102 is very close to 4".

and if the changes have nothing to do with structural problems over the years
then I will look for the original. Any info on the ULM? THX.

| Subject: | Re: Static ports |
I purchased the Dynon AOA and called them and zenith to get further clarification
of the location of the Pitot. Dynon said to keep it out of the boundary layer
of air around the wing surface. I think their document said something like
6" away from wing surface. Caleb and I figured the boundry layer wouldn't get
much beyond 4" at VNE on the XL. The design distance of the CH pitot has the
stand off at 2.5 for the static tube and 3.5 for the pitot.
I just measured the Dynon AOA on the wing I am building and I have it set 5.75"
from the wing surface to the center of the pitot hole. That should keep it out
in the undisturbed airflow. The rest of the position is just like the print
150mm back from the wing spar rivet line, and just outboard of RR#5.
Planning to mount the two static ports just like Mark Townsend said. It works
for him it will probably work for me also [Laughing]
