I agree with the racing part, but I bought a new Fatboy in 1998,
came to my senses in 2002, and the only thing I did to it was
add gas and change the oil. Sure, it rumbled and vibrated, but
I never had to push it!

Have had both Harley's & Honda's. Resale is governed by demand. When was the
last time you saw a used Honda Goldwing Interstate Aspencade go for the same
amount, same year as a like year plain Jane Harley. Or when have you seen a
Harley offered for sale less than $5,000.00, lots of late model Goldwings in
great shape for less than that.
HRII is as close to a poor mans P-51 as I've seen. Ya gets what ya pays for.

Hi Kevin
Kevin, don't be puzzled :-), because you're right. It was late and I didn't
feel like getting to in depth about it, but even as I sent it, I knew
somebody would call me on it. I'm certain that you have a better grasp on it
than I ever will, but what I should have said is that the PSS unit directly
measures air pressures on the top & bottom of the wing is actually measuring
the lift being produced, which most people simply refer to as angle of
attack, and lift really is what we want to know. (at least this is how I
understand it). The vane type is the only unit that truly measures angle of
attack directly. I feel that the PSS system is probably the most accurate as
it is measuring the component that is actually keeping us up in the air and
that is lift. I have to be honest and admit that I really don't know exactly
how Dynon is measuring it, but as they only have a single sense line plumbed
to the back of the pitot and then use the pitot $ static inputs, I can only
assume that it is inferential measurement, since they can't be getting any
direct measurement of angle of attack or lift on the wings. In any case, I
have found it to be as accurate as the PSS unit.
Ed, good grief, don't you ever sleep? I thought you already had allot of
projects on the go, now you tell us you're working on an AOA device.

For aircraft related ramblings please skip down one paragraph.
A little while back I had the opportunity to ride a Honda CRF250(Honda's
4
stroke dirt machine) and I was pleasantly surprised by the rumble when I
kicked it to life and was almost shocked by the pleasing note of the full
throttle roar of this machine (even more pleased by it's performance). And
yet I've been always annoyed by the obnoxious bark of Hawgs. The owner had
planned to install a Baha kit which would have made this machine street
legal and I had looked forward to a head to head against any Hawgs, but
unfortunately he traded it off as it was way too overpowered for trail
riding with his kids on their Honda 50's.
Now with this said I must admit that I'm not really crazy over the sound
of
my muffled turbo Mazda engine, which even though it is quit, doesn't have
the pleasing rumble of the Trans Am I had when I was a teenager. But I
prefer it over the obnoxious sounds of the unmuffled Lycs on my field.
I guess the sound of pleasure is different for all of us, but there is
no
denying that we are all facing pressure to restrict our flying activities in
not just urban US areas but also in the Canadian wilderness due to the
insistence of pilots to wear the muffler on their heads.
Todd (turbo, muffler, composite 3-blade prop, in every effort to not piss
off my neighbours. Non-asbestos(hey that stuff will kill you)suit,
HAPPY NEAR YEAR TO EVERYBODY

Err....
I might be mistaken, but it looks self evident that *some* auto engines have
an annoying sound in aircraft, otherwise why would they need them ugly
mufflers hangin' out?? OTOH, who would want to muffle the lovely sound of the
barkin' Lycosaurus??
On a serious note, a friend races rotary mazdas , and outside, they will
give you permanent hearing loss. Inside, much better, as I found out on a "track
day". So I think the Subie and Mazda conversions might be o.k. to the pilot,
but nasty sounding to buddies on the ground you're trying to impress...
BTW, I have a V4 Honda bike, and it makes nice music. Not as nice as a
Harley, but then I don't have to trailer it to Sturgis, either. :)
I'm sleepin' in Nomex tonite!!

Hmm, overpriced yes. They do regularly win various races especially under their
Buell name. As far as breakdowns go, you are thinking of the problems of the
80's and somewhat early 90's, not really a problem anymore. Oh ya, and then
there is that whole land speed record thing. :-) My Harley is less maintenance
than most of the Honda's, Kawasaki's, and Yamaha's I have owned before and
I have owned a bike since I was 5.

Yes, Dan. A good article - and if you don't have an extra airspeed
indicator you can order a 2" H20 differential pressure gauge which will also
do the job (and less expensive - as its not an aircraft part)

Hi Dan,
Actually at this point I am using a different probe for the AOA sensing than
the pitot tube. Its basically a bar of aluminum with a port drilled on one
side pointing into the air stream and one on the bottom of the bar This
probe is then mounted at an approx 65 Deg angle to the wing (pointing into
the airflow) so that both ports see the dynamic pressure. Then as AOA
varies - one port sees more/or less of the dynamic pressure component of
interest than the other port giving a pressure differential proportional to
the AOA..
However, my next version will probably be a combination of pitot tube and
AOA probe, it this one the AOA sensing ports will only be 45Deg apart to
make the probe serve as both a pitot pickup and AOA sensor.
I have a heated pitot tube, but had not looked into heating the AOA as I am
a dedicated VFR pilot. But, machining an insert for a heating element might
not be that bad, will have to look into it.
Ed

Hi Todd,
Well I finished the EFI Fuel Monitoring System and needed another project to
replace it. A fellow local Rv builder asked me to machine him an AOA probe.
So I got interested in the AOA and enjoyed working out the math - at which
point, I realized I had all the information I needed to build my own. The
nice thing is the "processing" part of the system can be as simply as a 2"
H20 differential pressure gauge OR (since I don't like long runs of tubing),
hook up a pressure sensor and microchip to display the traditional LED
ladder and add audio alarms. In fact, I am going to experiment and see if
bright LEDs laying on top of the instrument panel and focused on the
forward canopy could give a useful "HUD" type display for the AOA. I've
seen some folks mount the AOA displays on their instrument panel, but I
never see my instrument panel once I am on short final. To this day, I
don't know what airspeed I touch down at {:>), so a HUD type display might
work out OK.
Going into retirement with a "lifetime" of projects will keep you happy,
exhausted, and broke {:>) - but, I love ever minute of it. From what I have
seen of your projects, I don't think you will have any problem enjoying
retirement.

I am an airplane builder and also the local airport manager and I can
tell you that noise of any sort is becoming a real issue. I don't think
it will be that long before that nice rumble will get us all in trouble.
Enjoy it now because I think we are all going to be stuck with those 3
foot under belly mufflers before long. Airplanes are an easy target for
complaints, and you can't believe what some people complain about. The
low rumble of the radial and of the unmuffled experimental are big on
the list. As far as airplanes, I like them all if they fly good. As far
as bikes, I even liked my BSA, oil leaks and all. Sounded good to, at
least when it ran.

Noise (noiz) n. Sound or a sound that is loud, unpleasant, unexpected,
or undesired.
What might be music to one person's ears, is noise to someone else.
Particularly when nursing a hangover. :-)
I personally don't really understand why people like their airplanes
to make a lot of noise. I've flown aircraft with very effective
mufflers, and I don't feel any less "cool" knowing that I'm not
making a bunch of racket. In fact, knowing that the airplane is
very quiet, I don't mind flying over nature preserves, skiing
areas, lakes, and other places where people go to enjoy peace
and quiet. I enjoy flying, but I don't want to force others
to participate.
I think if we take an active role in reducing the amount of noise
our aircraft make, we'll continue to enjoy our hobby. Many pilots
I've spoken with feel that what will happen is that they'll
eventually be forced to put on mufflers, and the longer we can
delay, the better. I believe that the general public does not
see it this way - they will be happy to see the FAA or TSA or
any other agency simply shut us down.
I've addressed this issue with the AOPA, and they don't really
seem to be too interested in trying to get people to install
mufflers. Looks like we'll have to take the lead on this one
ourselves!

Mickey,
With due respect, are you really asking us to be on the forefront of hanging
ugly mufflers off our beloved RV's??? I too, think we should do all we can
to reduce noise as much as possible around airports by using appropriate
measures, but I like to fly high and fast cross country, and don't want any
stinkin' heat producing, horsepower robbing mufflers hanging out or crammed inside
an already tight cowling.
In other words, you can have my straight pipes soon as you remove them from
my cold, dead, hands... YMMV of course.

see it this way - they will be happy to see the FAA or TSA or
any other agency simply shut us down.
I've addressed this issue with the AOPA, and they don't really
seem to be too interested in trying to get people to install
mufflers. Looks like we'll have to take the lead on this one
ourselves!

When was the last time someone could hear a Honda coming?
I bought a 1984 Honda Nighthawk in 1998 for $700, complete with a spare
"parts bike". I thought it might be handy. The bike came to me with about
100,000km on it, and I put another 30,000km on it over the next 6 years. I
never did use that parts bike. But I did sell the bike for $2000 two years
ago. My Honda VFR (V-4 engine, gear driven cams) sounds like no other bike
on the road, and will never leave me at the side of it either.

For what it's worth, I have to be with Mickey on this one. One of the
reasons for being a good neighbor is to keep your neighbors from passing
laws to force you to do what being a good neighbor would have meant in the
first place. We all should know by now that the best way to screw up a good
idea is to pass a law that makes it mandatory. If we don't show enough
respect for non-flyer's sensitivities to the noise we make, we are insuring
the day will come when FAA inspectors will be sitting by the runway with
noise-measuring equipment writing violations for those that miss some
arbitrary standard. The longer we can put off that day the better.
Maybe some of you really smart guys can come up with a way to tone down a
Lycomming on an RV with the least loss of power and increase in weight.
Didn't I read here on the list some time back that the gentleman that builds
most of the exhaust pipes for us is working on it?

Mickey,

In other words, you can have my straight pipes soon as you remove them from
my cold, dead, hands... YMMV of course.

I think if we take an active role in reducing the amount of noise
our aircraft make, we'll continue to enjoy our hobby. Many pilots
I've spoken with feel that what will happen is that they'll
eventually be forced to put on mufflers, and the longer we can
delay, the better. I believe that the general public does not
see it this way - they will be happy to see the FAA or TSA or
any other agency simply shut us down.

The following is an unpaid public service announcement,

Re: "This is a very common sentiment. Like any red blooded American male I
fully
agree. The sound of those big engines, especially at idle, sounds so much
more manly than the high-revving alternatives... ...Look even
at the big war-bird engines of WWII - the pent ultimate in cool sound...
...I would love to own a
P-51, but I know I don't have that much discretionary money...
...nostalgia, but I
would never own one... too expensive and not worth the money...
...Choose your engine based on it's sound if you want - not a totally
unreasonable selection criteria..."
There are aviation museums dotted all across the country. They run on
volunteer talent.
Much (most?) of that talent is lay people, not trained mechanics or pilots.
Their biggest
asset is motivation and a willingness to work. A pilot, especially
one with tail wheel experience and who has built their own airplane, can be
a huge resource to
these organizations. The work isn't always fun, but it is rewarding, as is
the flying. And, the
only thing that sounds better than an airplane with an R-2800 is an
airplane that has two of them.... : - )
We now return you to your normally scheduled listing...
