Do any list members subscribe to the Zenair Newsletters? Ian, I have
subscribed to Zenair news since it was first published.
If so any comments as to the quality/usefulness of the publication? The
quality is first class! Chris Heintz started publishing in the 1970's, then
turned it over to somebody else when he realized it was a huge task that kept
him
from his primary task of designing. The publication has continued to
improve, as a result of Chris' support for what he recognized (and apparently
still does) as a critical part of his business.
On the face of it to me it appears to be necessary to ensure you have the
latest recommendations and safety information from Zenith. I agree with your
assessment. Each newsletter contains the following, packed into 12 pages:
1. Bulletins (important notices/updates etc)
2. Column written by Chris Heintz
3. Fly-in announcements and reports
4. Construction updates from Chris Heintz
5. Other suggestions from builders
6. Flying Zenair aircraft
7. New subscriber list
8. General news from subscribers
9. For Sale and Wanted ads
I have some
reservations about having to pay money for safety related and technical
information that should be readily available to anyone who has purchased a
set of plans or a kit. My advice: Don't let your reservations cloud your
judgment to the extent you deny yourself a valuable resource, available at a
very reasonable cost. If I ask myself "Is the publication worth an additional
$25 per year?" the answer is "YES, very much so"!! Try offering submissions
to the newsletter (Item 5 in list above) you may win yourself a free
subscription!
An E-mail service would be a low cost option. Try sending an Email to
newsletter editors Steve & Sharon Krog and ask - _www.sskrog@zenair.org_
(http://www.sskrog@zenair.org)
Are there any opinions out there? Uh huh, I reckon so.

Hi Ian,
The Zenair newsletter is not affiliated with Zenith in any
significant way. It is a separate operation with regular inclusion
of thoughts from Chris Heintz (who, for the most part, also has
nothing to do with Zenith).
My advice to you is to go ahead and subscribe for a year to the
Zenair newsletter and see if you find it valuable.

I received a notification that someone from Oklahoma
signed my guestbook. It's been a long time since I
looked at my web site usage and guestbook signatures.
After all, I don't maintain the site since quite a
while... perhaps I should start a new one with flying
experiences.
Anyway, I found that I have over 200 signatures (!),
over 50 000 unique visits. And there is still an
average of over 100 visits a week.
Thanks all!

Hi Ian,
I've subscribed to the Zenith Newsletter for the last 6 years and it's
been mostly informative and
interesting reading. Always time to slow down and get detail not
normally covered by magazines
and some for sale items have been helpful.

Hello Ian,
When I started building my XL from plans last year I subscribed to the newsletter
and also ordered 5 years of back issues. The newsletter is not "necessary",
but is fun to read. I enjoy the articles on other builders and their projects.
There is also a "For Sale" section in each issue that can be interesting at
times.
The latest information related to updates and technical issues can be found on
the Zenith online builder's pages. Personally, I think ZAC does a pretty good
job of posting plan and photo assembly guide updates.

Rich-
A final note. This e-mail may sound negative, but it's actually a
good thing. You'll find you actually save time by taking the time to
fully research any procedure you're unsure of before cutting metal. You
just have to get over the self imposed time line we all had when we
first started.
Good building!

As an official "old geezer" (started my career before computers and ended it as
a school tech director) I must say that the web is a wonderful thing. Sure
there is a lot of junk out there but when you sift thru the sites there is an
incredible amount of info available. Sites like yours are a great help to those
of us who are building (or contemplating) building an aircraft. I ran a network
link for my laptop out to my workshop so I can study selected builders sites
when I bump into a question or obstacle. Builder's sites and this discussion
group make building so much easier than it would have been before the internet
age. Thanks to all for sharing!

I would love to see your reference on this one. The
Texan I fly on weekends has the tips go supersonic
just about every flight. I haven't done the math, and
don't care to, but you can hear the difference when it
takes off. When I take off, I pull back the prop as
soon as I get the gear up, and it purrs by. Most of
our pilots leave the prop up until at altitude. The
sound is a high pitched whine. The difference in RPM
is only 100 - 200. You can often hear the same thing
on Bonanzas and others if the prop is left up.

Mine works fine with my Garmin 196. Doubt you'll use all the pins you
have on the back of the 296 but you could call Garmin help and I'm sure
they'll be on the ball as they are one of the most customer friendly
companies I've dealt with over the building/flying time period.

Hi Brandon,
No, I don't have a specific reference on the supersonic prop tips. I
wonder if your Texan tips are actually going supersonic or if they
are just transonic. Do you get a sonic boom?
There is a nice prop tip speed calculator on the Culver prop web
site. You can plug in the RPM and prop diameter to get an estimate
of the mach number for the tips. Of course, mach number varies a
great deal with air conditions, but it still might be interesting to see.
I am amused by the responses I am getting to a post I didn't think
would be at all controversial. I was merely trying to help Robert
understand the answer to his question of why some engines run at such
high RPM. Your question about tips going over mach 1 was also
mentioned by Roy while he strongly defended the ancestry of the Rotax
engine design. I guess I am just an irritating guy . . .

I'm only going to tackle one question you asked.
About the high RPM of the newer engines. Horsepower is a factor of many
things a few of which are the displacement of the engine and the number of
power pulses per minute. Increase the number of power pulses and you
increase the horsepower. Of course there is a level of diminishing returns
on this or we would all be driving cars with thimble size engines turning 5
million RPM. And producing 500 hp.. Older engines were designed for the
props they would be turning. Those props were most efficient below 3000 RPM
so the engines were designed to have a max RPM of below 3000. They
increased their power by adding cubic inches. Basically bigger cylinders
and more cylinders. Quite a few of the radial engines had planetary
reduction gearing in the nose that allowed than to max out at around 5000.
A few things to consider are the improvements in engineering and materials
in the last seventy years. Newer bearings, cylinder walls and better
cooling methods allow much higher revving engines.

I have had my prop at 1.2 mach. In fact it gets over mach everytime I
fl
y. 76" three blade inflight adjustable Ivo. 160+ hours and the tips look
as good as the day I installed them.

WOW!!! At 70 degrees F that is 3400rpm for Mach 1.0 and at Mach 1.2 that
is around 4100rpm! I am surprised that the prop can take that!
