I have the series one and series two Bose headsets in my RV 6. Both
interfaces are wired in with a selector switch to select which one is
connected to the Push to talk switches located on each stick. I have used
them in everything from B-727 and Cheyenne III aircraft and would not fly
without them. The reduction in fatigue is worth the money alone. I have tried
the David Clark ANR model and returned it immediately due to the heavy
clamping pressures and drumming sounds during use. The Bose series ten was
not suitable for me due to lack of comfort but everyone has their own comfort
zone.
Additionally, the service received from Bose is worth the initial cost. They
will fix almost anything you can due to your headset. I had a flight engineer
pinch my coiled cord during a seat adjustment and Bose replaced the cord with
new parts and returned my headset with new ear cushions free of charge.

I have tried Lightspeed XL (the first ones out), Bose, and Peltor passive
headsets in my 8. I like the Lightspeed the best in the RV, and I am hoping
to upgrade them at sun n fun for the latest ones. They are not as
comfortable as the others.
The 8 is really noisy, even with sound foam on the firewall, and foam and
carpet on the floor. The Bose headsets are overloaded, and the noise
cancelling cannot keep up, and then quits altogether. The Bose are very
nice, comfortable headsets, and they are by far my favorite in my C-185, but
they just can't hack it in the RV. I have heard this from others in the
noisier airplanes.
The Peltor is a fine, basic headset.

If I may piggyback on this one......
How about purchasing one of the non ANR units and modifying it yourself?
Has anyone tried this? It seems like a savings of over $300 EACH! There
was an article in either Kitplanes or Sport several months ago detailing how
to mod your headset for a very nominal cost. It sure seems like it should
work. Any actual experience out there?

George...
I had a set of LightSPEED 20K's for about a year and the only think I didn't
like was the bulkiness and the fact that they were somewhat fragile in the
cold... Last June or so, I traded then in for a pair of LightSPEED QFR
Cross Country's and LOVE them!

You can get then right now for $260 from Marv Golden.

I used the Headsets, Inc kit for converting a David Clark headset to ANR and
it works great ... can't tell a lot of difference in it and my Lightsspeed on
noise cancellation.
I am sending in my Lightspeed 20 XL for the new 3G today. I like my
Lightspeed a lot and the ANR is great even in the RV. I want the separate
music and cell phone in put which are on the 3G. I love the idea of being
able to upgrade.

When I did my headset shopping (8 years ago), it killed me to spend that
much on the Bose but nothing else came close to their ANR performance. I
understand that the others have made a lot of progress since then.

The Bose headsets are without a doubt the most comfortable I have ever put on.
As you point out, they are so pricey. However, ranking right up there in terms
of comfort are the Flightcom Denali's. These have a very similar design as the
Bose - offset earcups to match how your ears are REALLY shaped and molded foam
in those earcups to match the contours of your skull. Both designs rely on
quality and exactness of the fit rather than squeeze pressure.
The Denali's are available in a passive (non-ANR) set for around $289 and the
ANR set for about $550. I have two of the passive units (long story, but I got
both for a really good price as part of a warranty trade in on an old Eclipse
model - I have been nothing but impressed with Flightcom's customer service). I
(and my young children) have worn these for up to three hours straight with NO
discomfort.
Again, having a design that does not rely on the clamping makes ALL the
difference.

I have been privaleged to fly with nearly all the headsets for many hours. I
never take for granted the benefits of selling new (production) aircraft.
After trying Lightspeed, David Clark, Sennheiser and Bose I can say Bose is
WORTH EVERY PENNY.
But, it's a lot of pennies. If your budget allows, I wouldn't buy anything
else.

Van's kit tires are really worthless. Mine lasted a little longer, to 140 hours
or so. I had landed at Telluride, CO and parked only to find a flat tire.
Further inspection revealed a pin hole leak in the left tube (no obvious cause),
but both main tires had excessive tread wear. I junked tires and tubes and put
on Flight Customs.
As to plys, as I recall, the rated weight for a six ply is something like 1200
pounds while a 4 ply is about 800. I got 6 ply to be on the safe side. That was
the first flight tire I have had in any airplane in 35 years and I don't want the
experience again.

What tires did you get from Van's? Can you determine why you need new tires
after 57 hours?
I have over 90 hours on mine so far and they still look new!

Len,
I like the six ply. Makes for a stiffer, more durable tire in my opinion.
Condors and Dresser retreads make very solid tires for the RV and are quite
economical. Landing technique has a LOT to do with how long the rubbers
last!

As the author of the article, it's nice to see that there's people
making use of it... Makes me wish I had put a web counter on it.
The QFR X-C started life as the QFR Solo, which on its own was a very
good Passive headset. Adding the ANR circuitry has raised it into the
realm of headsets like the Lightspeed 20XL and Bose X, at a small,
small, fraction of the cost. While I wouldn't claim that the QFR was
equal to the Bose, i'll definitely state that it's better than the 20XL.
The biggest factor to remember about the QFR X-C is that if the ANR
circuit ever dies for some reason (ie. batteries die, you forget to turn
it off, or some other reason), you're still left with a good Passive
headset. I don't think Bose or Lightspeed could make the same claim
about their ANR-only models. And certainly in our testing we showed
that the 20XL with the ANR turned off was only marginally better than
not wearing a headset at all...
This same backup feature can be said for the David Clark ANR models, but
many don't like them for the same reason they don't like DC's in
general, ie. the high clamping force on the head. Personally I like my
10-13.4, and find it quite comfortable (and I have a larger than average
head, too), but ymmv.
Feel free to grill me off-list, George, and i'll tell you anything I can
about headsets... We learned quite a bit in the testing we did for that
article.

| Subject: | IFR Prof.Check Ride, was IFR in RV's |
--> RV-List message posted by: mstewart@qa.butler.com
I took all of my IFR training and my checkride in my 6a.
I guess it went well since I am still here to talk about it.
Both the possible examiners did not have any trouble giving the test in the
RV. But One I tlked to would not give it in an experimental.
My DER, with over 30,000 hours, had never given a test in an experimental.
He thoroughly enjoyed it. He has since given 2 other IFR checks in rv's as I
have sent people to him. Hell he maybe pounding rivets into a tail kit as we
speak. He loved the RV and spoke of maybe building one. He is 77 years old
and still flying and instructing. Got to love that.
I busted my first ride due to pilot error. I was asked to perform a DME
hold, which I had never done, and which I did not even know existed.
Had to come back the next day and perform one. Was not a big deal. I did not
even know my Garmin 295 would perform such a thing. (OK I perform it, but I
just follow the picture on the screen. HEHE!) Now I know. But have never
been asked to do it since.
During the check ride, I would fiddle with the VOR dials as if I was
following them, but was flying completely off the 295 for navigation on all
approaches and holds. And it is how I fly now. I occasionally fiddle with
the VOR's just so I can be somewhat familiar with their use. But I NEVER use
em. Me and My 295 have developed a very close relationship.
I would not enter hard IFR w/o my NavAid though. I probably enter actuals at
least every other week as I travel a lot in the RV for work.

Just out of curiosity,has anyone with an IFR rated RV
airplane taken their instrument profiency check ride
in their plane,and if you did,how did it go? Thanks.

--> RV-List message posted by: Bob Japundza <bjapundza@yahoo.com>
Over the past three years I have tried several
headsets, and spent a few hours flying with each.
My number #1 choice is the Peltors with the large
earcups. I have the 7005's with the Headsets Inc. ANR
conversion. I flew about 10 hours with the Bose X's.
The Peltors with the conversion beat out the Bose X's
hands down IMHO. I was pleasantly surprised. The
Bose headsets have a small earcup and it places
pressure on your ears; after a few hours it gets
uncomfortable. Also, there is less passive
attentuation because your ears do not get sealed very
well. The Peltor 7005's have large earcups that
completely surround your ears; thus not placing any
pressure on them. The headband is very thin and
comfortable which makes it ideal for use in the RV. I
have never had my Peltor's clamp or discomfort me in
any way even on long trips. Every other brand did.
I used some Lightspeeds for a while, liked them but
didn't like how close the hard plastic headband came
to the canopy, and I had to duck when opening/closing
the canopy, otherwise they would catch.
I had a set of older Peltors that I sold, because the
smaller earcups put pressure on my ears, just like the
Bose X's.
The QFR's were good for being inexpensive, but a
little uncomfortable for my ears. The mic on the
QFR's was the best. I had a pair of those also, and
sold them to my neighbor. He loves them.
DC's and clones were the most uncomfortable and didn't
perform as well.
The Headsets Inc. ANR conversions made one heck of a
difference. Not only did it make things quieter, but
the sound quality was vastly improved; listening to
the cd player in the airplane is almost like sitting
at home in front of the stereo. When I bought the
conversion kits the Headsets Inc. rep told me that
they are now the OEM to Peltor for their ANR headsets.

I have an IFR RV6A that I have flown IMC many times and shoot approaches to
500'. Just put about 4 hours of IMC on the way to Florida and back. The auto
pilot had failed so it was all hand flying. I have not taken the IPC but I
am a CFII. I find the plane comfortable in IMC but does take a proficient
scan, not one you can "go to sleep in"

--> RV-List message posted by: czechsix@juno.com
Guys,
I'm one of the masses eagerly awaiting the Dynon EFIS D-10 that is supposed to
be available shortly. Before I send them my money, however, I think it would
be nice to hear from someone who is not a Dynon employee who has flown with the
unit...always nice to get a review from somebody with a different perspective
and hopefully as unbiased as possible...at least without a conflict of interest!
A while back there was talk of Dynon sending out beta test units to a few people.
Is anybody out there a participant, or know of anyone who is? I expect Dynon
may have made a beta tester sign some sort of nondisclosure agreement during
the test phase to allow them to sort out any problems without negative press,
but at some point we should be able to hear from those folks...
I also asked Dynon about this and have not received a response yet...will post
it if I get any information. I'd encourage others interested in seeing a 3rd
party review of the unit to contact Dynon expressing this desire...write them
at info@dynondevelopment.com

Isn't this exactly the problem someone was alluding to earlier? That if
you don't know what you're doing you shouldn't be up there in IMC? And
to make it worse, you brag about "putting one over on the examiner" by
playing with the knobs but ignoring the equipment during your ride.
Personally I wouldn't want the extra weight of equipment I had no
intention of using. If I did get into a situation where I needed to use
my backup equipment, I would want to be *very* proficient in it's use in
order to reduce my workload. I wouldn't want to be re-learning how to
use the steam gauges when i'm unexpectedly in hard IFR.
Just my opinion, of course, so DO NOT ARCHIVE.

Rob,
On you IFR checkride you are allowing to use anything in the aircraft,
unless he is having you do partial panel, to moniter the ground facilities
to be used and maintain situational awareness. I'm sure he had the needle
of the VOR somewhere around the donut, or the examiner would have pink
slipped him. They are not that stupid.
Example, your are shooting an NDB approach where total deflection indicates
your missed approach point. If the localizer approach to the same airport
has DME, you are allowed to use the DME equipment for situational awareness
even though that is not a ground facility represented by the NDB approach.
My instrument examiner asked me why I didn't use my handheld during my
checkride for situational awareness.
I hate to get into these types of discussions but that opinion about an
instrument ticket being needed to fly at night just doesn't hold water with
me. VFR at night, some of the most beautiful and peaceful flying there is.
Center that localizer, hit "go to", couple to experimental autopilot and
track straight in. Not much too it.

OK for the five hundredth (too low?) time. DO NOT TAKE OFF ALCLAD!! If you
want to prime then prime. The idea of priming along the rib line is so that
if water (especially our acid rain in the North East) should get between the
joints and linger, there MIGHT be some corrosion that would take place. It
MIGHT take years to occur. If you want to use the least amount of primer but
want to prime, then prime where pieces overlap and areas that will be closed
in forever; like under the floor.
Me, I'm priming most everything with a zinc chromate based primer but what
do I know.

heard many say that you want to prime just along the "rib line" of the

then is primer along the inside skin "rivet line" really necessary.

I swear by Michelin Air tires. Northwest uses them on all our jets. I have
them on my RV-4 and noticed a nice firm feel in handling at all speeds. I
do not have gear leg stiffeners and sometimes I would get a mild gear waggle
slowing down with the old tires. That all stopped with the Michelins.
Get 'em at Desser Tire 323-721-4900. Not cheap but they will last a long,
long time. Michelin tubes are also great. I never have to add air (again,
not cheap but you get what you pay for).

Just a little story about my limited experience with ANR headsets - for
what its worth. FYI - I'm building an 8A and I'm in the market for
headsets.
I don't know if the Bose headsets are worth the money or not - never
tried them. I do know my wife flew with the Bose X in her boss's plane
and she thought they were uncomfortable to wear.
But, a friend of mine has Headsets Incorporated noise reduction kits
installed in David Clark headsets. He flies an RV-6 with an O-320 and
they work pretty well. In fact, his modified David Clarks seem to reduce
noise better than another RVer's David Clark factory ANR.
How well? I recently ordered a new Telex Stratus digital ANR headset
and two of my friends tried it side by side in the RV with the Headsets
Inc. kits in the David Clarks. I didn't get to fly with the headsets myself,
but both of these guys are RVers, and I trust their judgement. The Telex
was no worse, but, no better either. The Telex Stratus was $700.00.
The Headsets Inc. kits are $169.00 a kit. I sent the Telex back. (The
Telex WAS very comfortable to wear, however)
Headsets Inc. is now offering a complete headset of their own for
$399.00 with the same ANR circuitry as their kits, web site:
www.headsetsinc. com. I haven't ordered one yet, but I probably will,
to try it out. I've got a new Peltor GT Pro headset on order to try out first.
FWIW - I've been told that there is no industry standard for testing ANR
headsets, or for charting performance curves and graphs. Compare the
performance curves of the Telex to the performance curve of the
Headsets Inc. and it would appear that the Telex should reduce
significantly more noise. In the real world, it didn't. (both performance
curves are on the respective web sites) Without an industry standard,
the advertising hype means little.
I think headsets are a very subjective thing and you just have to try
different ones. You will be out a few bucks for the shipping if you
return them, but that beats a $700.00 mistake.

Firewall Penetrations
Firewall Penetrations-by Vern Darley (vern@mindspring.com)
Years ago,I was an Air Force Force pilot and had a jet engine throw a compressor
blade thru the
cockpit and hit the side of the ejection seat. The cockpit immediately filled with
intense heat
and I was solid IFR with dense white smoke inside the cockpit. In another type
of AF plane,I
once experienced an electrical fire in the cockpit. In college,I worked parting
out crashed
light aircraft at an FBO. Lately,I've wandered around aircraft junkyards scrounging
parts. All
of these experiences have made me accutely aware of how much I want to keep fire
out of my RV
cockpit.
In the RV world,there are four main penetrations through our firewalls: engine
controls,fuel
lines, wiring, and cabin heat/air. Due to their small size and the availability
of
'eyeballs',etc. engine controls are not a big threat to us. The fuel line penetration
is
normally handled by a through-the-firewall fitting. So, there remain two main threats
to our
health and safety: the wiring bundles and the cabin heat/air.
Typically, most builders seem to opt for the rubber grommet and a dab of RTV for
the wires,and
depend on the aluminum cabin heat devices that Vans and others market to cover
the
two-inch-or-so firewall penetration for air. In my opinion, the aluminum devices
are inadequate
protection to keep fire on the engine side of my RV. In searching for solutions,
I found a new
company that has helped me solve these problems. I asked them for data,and Paul
Bowmar, director
of R&D provided me with a video of a recent test he conducted on aluminum vs.stainless
firewall
penetration devices. His company,EPM.AV Corporation, has developed a beautiful
stainless version
of the airbox most RVs need and has also manufactured various size wiring pass
throughs.He has
also tested various compounds that seal the wire bundles.
In the tests, a standard aluminum RV style vent was subjected to a flame source
at the 1600-1800
degree range that one would get in a fuel fire in a flying RV. The aluminum vent
melted like wax
within ten seconds! Even with a stainless flapper installed, this would not have
protected us
since the flapper would simply fall away when the supporting aluminum structure
melted. Tests on
an all stainless version of the same airbox endured extended direct flames with
no damage for
the duration of the test. Tests with wire penetrations yielded similar results
and pointed out
the need to use top grade wire and insulation for your through-the-firewall wiring.
I've since
bought actual products and am happy to report first class workmanship and to recommend
their new
products to my fellow RV'ers.
Fly safe!

Has anyone successfully built a homebrew autopilot? I'm the sort

information on the subject. I understand fully how autopilots work, but I'm
looking for information on how folks have actually built a system

The headset thread has been interesting but I am most impressed with how
many different sets of headsets people have had. It sounds like they are
changed with the seasons. There are references to many different sets of
Light Speeds, for example, with the old model being traded in for each
new model that comes out.
Am I unusually undiscerning or something? I have tried a couple of noise
cancelling types and did not feel like they were worth the weight and
complexity and strange problems they had. For one thing, they reduced
the noise only in certain bands, still leaving a lot of noise.
My copilot David Clark H10-30's are the set I bought around 1976 when
headsets first started coming into general use in general aviation. Boy
was it great to be able to actually hear what ATC was saying for the
first time. When I bought my first airplane, a Pacer, in the early 90's
I splurged on a set of H10-13.4's, since one set was no longer enough.
The DC's need new mike muffs every few years, but other than that, they
have given no trouble, haven't used any batteries, and frankly I don't
think about them. Friends with the high-tech gizmos like them, but they
have to send them in for repairs and such and they feel the need to
upgrade every so often.
Me, I'm happy. I can hear ATC, they can hear me, the passenger and I
communicate easily, and the noise level is not obtrusive. OK, maybe that
last is because I started flying when no hearing protection was the norm,
and compared to that, the passive headsets are a huge improvement.

Len:
The problem with the aero trainers will be obvious when you remove them and
compare to the new Goodyear tires. Personally, I use Flight Custom II retreads
on my Grumman Tiger and have for many years.
What you will see, and feel, is dramatic. The aero trainers are very soft and
flexible, almost like putty. The Goodyears are much stiffer and seem to be made
from an entirely different material. Believe me, when you make this comparison
the difference will be clear.
Just looked in my logs. The RV main tires lasted 138 hours and 5 months (nose
tire still installed and wearing fine). The mains on the Tiger lasted 4 years
and 828 hours. The prior set lasted 6 years and 714 hours. Both aircraft are
used for long cross country travel and never any touch and go work. I am the
only one who flies them, so I think the comparison is valid. FWIW, the Tiger
nose tire, used properly for the purpose of keeping the prop from hitting the
ground when taxiing and not for three point landings, lasted 10 years and 1542
hours. You will get your money's worth with the Goodyear line.

One small detail on headsets...
I have Lightspeed 20XL's and like them fine, but when I climbed into my
unfinished RV-8 to find a convenient place for the headphone jacks, I
realized that the cord for the 20XL's and probably all Lightspeeds comes out
of the left headphone, which is the wrong side for a tandem aircraft. It
will work, but it would be better if the cord were on the right side when
climbing in and out. I mentioned this to the Lightspeed representative at
the Western Washington aviation conference last weekend. He was pointedly
uninterested.

Somehow, I feel it unethical to cut and paste a posting from another
person directed to a group
on another website. If you are of a mind, check out the
ExperimentalAvionics Yahoo group
for an interesting tidbit regarding a possible new avionics release in the
very near future. Can anyone
add any more information?

It was done in the '70's or early 80's using thermal sensors & an air
stream as the rate gyro and air bellows made from coffee cans as the
servos. Later modified to use model airplane servos to drive trim tabs.
I had one in a T-18 but the autopilot portion wasn't functional & the
builder was dead when I bought the plane. The solid state rate gyro is
probably down in my hangar but I've been through two moves & I can't put
my hands on it at the moment.
I believe that there were articles in Sport Aviation detailing
construction of this a/p. Try writing EAA about it.
Googling 'homebuilt autopilot' turned up this link:

As another point of reference, I got 170 hours or so on a total of 3 of the
original aero-trainers. The 3rd tire was the "good one" left over when a
buddy did his first tire replacement. Both of us found that the left tire
wore much more than the right tire on a conventional gear RV. My
speculation is that this is from the effect of torque on takeoff.
I just switched to the 6 ply Condors. One obvious difference is that the
Condors have a much more square footprint than the aero-trainers. This
required a fair amount of modification to the wheelpants. Also, they are
stiffer and heavier.
Something I dealt with from day one with the aero-trainers was landing gear
shimmy if there was over 22 psi in the mains. I've run the Condors up to 25
lbs so far with no shimmy. I don't understand why the new tires have
changed the dynamics here, but I'm happy with the change.

I hate to get into these types of discussions but that opinion about an

Ollie, that's why I should have just kept my mouth shut and went on my way.
The opinion was you should have an instrument ticket to fly at night, not
"you should have an instrument ticket to fly off runway 23 at Ceder Key on a
dark night without instruments". I understand what you are saying and like
I said, I should have kept my mouth shut and pounded some more rivets.
Boy, I could bring up the prime/not prime thread again.........or nosewheel

| Subject: | Re: Prop testing data posted |
--> RV-List message posted by: Kevin Horton <khorto1537@rogers.com>
I finally found the time to take a look at the cruise performance
comparison that Randy Lervold did between a Hartzell HC-C2YK-1BF
prop, and a Whirlwind 150. Randy's data and comments are at:
http://www.rv-8.com/Prop.htm
My comments on the climb perf were posted a few days ago.
I developed an approximate drag model for the RV-8. I started with
the drag data that the CAFE Foundation published based on their RV-6A
tests. They published enough data for the induced and profile drag
to be calculated. For the RV-8, I assumed the induced drag will be
very slightly less, as the wing panels are a few inches longer (yes,
the span is the same, but the -8 fuselage is narrower, so the wing
panels are longer). So, I assumed that the Oswald span efficiency
increased from 0.85 (what the CAFE foundation calculated for the
RV-6A) to 0.86. Note that at the cruise condition tested by Randy,
roughly 90% of the drag is profile drag, so this tiny change in the
assumed induced drag doesn't have much effect on the results.
Next, I took the CAFE Foundation RV-8A data, plus Lycoming's IO-360-A
power chart and Hartzell's prop efficiency map. I tweaked the flat
plate drag area to make the top speed match the CAFE data. Then I
tweaked it some more to increase the calculated top speed 2 mph to
match the difference in performance that Van quotes between the -8
and -8A. I ended up with an assumed flat plate drag area of about
2.13 square feet, compared to about 2.32 for the RV-6A.
Then I crunched Randy's test data for the Hartzell prop. I came up
with a calculated prop efficiency of about 77.5%, which is a fairly
close match to the 78.1% that the Hartzell prop map predicts. Based
on the Whirlwind cruise data, I calculated a prop efficiency of about
72.7%.
Then I took the 72.7% efficiency for the Whirlwind prop, and
corrected the temperature to match the temperatures seen during the
Hartzell test. The reduction in temperature from about 26 deg F to
about 15 deg F results in a predicted speed decrease of about 0.5
mph. At first I was surprised to see the predicted speed decrease
with a decrease in temperature, as I expected the increased power to
result in a higher speed. Then I realized that the power changes are
overshadowed by the increase in calibrated airspeed. You see, if
everything else is the same, the drag depends on the CAS (actually,
it depends on the EAS, but that is essentially the same as CAS for
the altitudes and speeds we care about). So, if we decrease the
temperature, you need to fly a higher CAS to get the same TAS. The
drag goes up because of the higher CAS, and the plane goes slower.
This is why we get a higher TAS for a given power if we increase the
altitude. The lower CAS as we increase the altitude reduces the drag.
Just to make sure I wasn't completely out to lunch, I looked at a
Cessna 182 POH, which has cruise perf charts giving speed for various
rpm and MP values at different temperatures. Sure enough, if you
keep the same rpm and MP, the 182 POH shows an increase in
temperature results in a higher TAS. A Piper Saratoga POH showed the
same thing - for a given rpm and MP, and higher temperature gives a
higher TAS.
Then I corrected the Whirlwind speed by increasing the weight to
match the average of the weights flown with the Hartzell. That
resulted in only about a 0.15 mph speed reduction. So, at the same
conditions as Randy flew the Hartzell, I predict that the Whirlwind
150 give a TAS about 4.5 mph slower than with the Hartzell.

The pressure switch is available from Van's. EI-4006-4 for $23.79. It is
the SPDT switch which can also provide a low oil pressure signal.

For those who get miserable tire life, something strange is going on -
alignment or something. I just chucked the Van's Aero Trainer mains
from my plane after 324 landings, of which probably 40 were on grass. I
rotated them inside out about halfway through, and the tread lines are
still visible in about 95% of the surface. Replaced them with Michelin
Aviators, can't really tell anything different in handling, but I
believe the black dust which used to collect on the wheel fairings is
greatly reduced.

Gabe Good on you and very very lucky boy. I knew someone in Denver that
didn't lock his tipup. It opened about 3/4 open and spoiled the air over the
tail. He lost a lot of height trying to reach and close canopy. Luckily he
was high enough to sort things out otherwise he would be dead. Because of
him I double check .

Kevin,
We knew we could count on you! Thanks for the analysis, very interesting
even though I only understand about half of it, but I guess that's what we
get when we ask a real test pilot (not a wannabe) a question in this area...
;-) As I understand the bottom line you believe my data, while not exact,
does show a fair approximation of the relative differences, correct?
Question for the future reference. I have been using msl altitude for my
tests so far. The good news is that the local barometer setting both days
just happened to be between 30.1 and 30.2, at least close. My Air Data
Computer computes real time density altitude. Should I be using that instead
of the msl?
Thanks,
Randy

I guarantee you it won't open 3/4 of the way open unless he was in a

Thanks to everyone who replied to my question, are Bose headsets worth the
extra money they go for (used) on E-bay? Answers indicate it's about a 50/50
split between those who love their Bose headsets and those that have tried
them and prefer other makes, or suprisingly other Bose models. For the
archives here is a summary of the answers re Bose followed by some general
headset answers.
Bose heavy, prefer Sennheiser HMEC 400.
Prefer Peltor 7005 with Headsets Inc ANR conversion, Bose puts pressure on
ear.
Tried Lightspeed, David Clark & Sennheiser, Bose best, wouldn't buy anything
else.
Bose most comfortable, Denali a close second.
Like 8 yr old Bose.
Like Lightspeed better in RV, Bose can't handle the loud noise in RV however
prefer the Bose in my Cessna.
Using Bose series I & II in RV, would not fly without them. Bose series X
not comfortable for me.
Tried & returned David Clark ANR.
Using Lightspeed 25K, Do not think that friends Bose was worth the extra
money.
---------------------------------
General comments - David Clarks heavy & have too much clamping pressure,
Lightspeed XL series have good electronics but too fat headband, DRE-6000
best for money, David Clark ANR and Flightcom Classic ANR work really well
in RV, traded Lightspeed 20XL's for QFR's and love them.
All comments about Headsets Inc ANR kits were positive.
Thanks guys, from all your feedback I have decided not to bid on the Bose
headsets on E-bay. I currently have passive Peltor 7004's and find them
comfortable, so, anyone have Peltor ANR's they want to sell?

One important point to understand with this statement is they are and have
been very honest with everyone on product results, delivery, development
and testing to date results. In our industry what more can we ask for but
this??
