Subject: | Angle of attack indicators... |
Russ=2C
Apologies for not get right back to you. I haven't forgot you=2C just a
little busy.
Regarding that Lift Reserve Indicator that Rick shared=2C I did share it
too=2C and I also built one that I can detail the steps how I did it. I h
ave a OEM one=2C and made my own duplicate version.
FYI for those thinking about making one for themselves=3B the factory u
ses the Dwyer 0-2 inches of mercurygage=2C but Dwyer makes an exact same ve
rsion that lists the column in CCs. I bought four and they arethe same mod
el except it is marked metric rather archaic inches. But=2C in any event
=2C it doesn'tmake any difference in the world what the markings are=2C all
we care about in our uses is the scale fromzero to full. Inches or CCs ma
ke no difference. I'll find the model numbers of the ones I bought.
In the meantime=2C Russ=2C while you are waiting for me to get with the p
rogram=2C peruse Bob Nuchols' (of Aeroelectric fame's) list of various AOA
and LRI articles.

of excuses=2C and some legitimate reasons. I quit work 9 years ago (I was
a concrete contractor) but didn't have any money coming in=2C relying on my

take to get my tail wheel endorsement=2C and updated BFR.
Ahhh=2C then the main reason. Two years ago I mentioned I had a tremendo
us attack of glaucoma. In the course of one month=2C I lost about 50% of t
he vision in my left eye. Gone forever=2C ain'ta never coming back.
As if that wasn't enough=2C last year in January I had a major medical ca
tastrophe. Lucky to be alive. $50=2C000 in medical bills=2C including new
double cataract surgeries to replace both lenses due to cloudy vision.
This year I am still trying to recuperate from last year's fiasco. I am
almost there....or at least as good as I'm going to be.
I sold the GlaStar kit I was working on=2C and now have the money=2C but
presently my focus is on restoring a '66 Mustang fastback.
I plan on keeping my Kolb=2C and anticipate being able to fly it in a yea
r or so.
Everybody=2C
About two plus years ago I shared with this list a home-made AOA indicato
r (I think) using a Hall Effect circuit=2C magnet and torpedo pointer looki
ng thing. I know I shared with list the home-made "lift reserve" indicator
. I have one "store bought" model (made by LRI=2C Inc)=2C and I also have
one I made exactly like it myself.
If anyone is interested=2C I'll dig through my files and see if I can pos
t them again.
Best regards to all=2C Mike Welch

Subject: Kolb-List: Angle of attack indicators...
Hello Kolbers=2C There is a big push by the local fight safety organization
s here in Alaska to get pilots to install Angle of Attack (AOA) indicators.
Every year we lose at least several pilots to low altitude stalls while ci
rcling big game animals=2C in addition to other stalls causes. The military
pilots=2C tell me that AOA was the way they were taught to fly since the c
onfiguration of their planes were often changing in flight. I am not planni
ng on installing rocket pods on my wings=2C but to me the AOA sounds like a
good idea for at least a low time pilot=2C if not everyone. Are there any
AOA equipped Kolb=92s out there? Thanks=2C Nick Cassara 607AK =85starting t
o look like a plane! =0A

Subject: | Videos on Finishing Latex Paint |
I've added a new Micro Mong page and 2 new videos the the wienerdogaero.com website
that show the sanding and polishing process for latex paint. Each is about
12 minutes long and show the finishing of one panel on the Micro Mong wing.
They're not terribly exciting, but they will give you an accurate view of what's
involved. The process is simple and doesn't require much for specialized tools,
but it does take a little time. I would guess about 6-8 hours total to get
both sides of the wing done, but you only do it once. The high gloss might not
be what everyone wants, but you still might find it interesting.

Subject: | Re: Angle of attack indicators... |
Joe, The carb synchronizer that's used for Rotax two strokes has two hook
ups. You can make one from 20 feet of 3/16" vinyl tubing and a 6' piece of
1 X 6 for less than $10. If you use water with red food coloring it reacts
faster than using ATF.

I notice that the Kolb website gives the same climb rates and takeoff distances
on the Mark III with both the 80 and 100 hp 912. What have others discovered?
Does the 100 hp offer any advantages/disadvantages on this airframe over the
80 hp?

Subject: | Re: Angle of attack indicators... |
AOA systems compare either pitot pressure or pressure in a port just aft
and above the leading edge of the wing, to either a 2nd pitot input
angled downward, or pressure in a port just aft and below the leading
edge of the wing.
If you see a water column gauge with only one 'port', there's another
somewhere on the device; you just can't put a hose on it. A differential
pressure gauge will have 2 ports that you can access. Here's one
http://www.ebay.com/itm/230564187946?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
that some with cooling issues are using to compare plenum pressure to
cowl pressure after the heat exchanger (or engine, for air cooled engines).
Download the links from the Aeroelectric site & you can see a couple of
examples of pitot style dual ports. If you google the term, there is at
least one commercial product for homebuilts that uses tiny holes drilled
in the nose skin of a wing, just above and below the leading edge. These
holes are plumbed to a differential pressure gauge with an analog
display, and a tone generator that can be wired into the intercom.

Subject: | Re: Angle of attack indicators... |
Tone generator? Now we're talking (ha!). I can easily see how to make a
sensor by adding a second pitot tube at 45deg or so from the standard one,
but I would want an audible warning, even more than a gauge. Allows to keep
your eyes outside, especially when flying low and slow while watching
things on the ground. So, how would one convert a pressure differential
into an analog electric signal that can drive a varying tone for your
headset or loudspeaker (plus maybe some electronic indicator)? Should also
be easier to calibrate than changing sensor angle.
Can someone figure out how to feed a signal into a tablet and use its amp?
Is there an app for that?
(I am hoping to take advantage of the recent advances in consumer
electronics by using a tablet and something like the iLevil to come up with
an inexpensive "glass" panel.)

Subject: | Re: Angle of attack indicators... |
Cessna has a small sail switch built into their leading edge. its positio
n is calibrated so that it rings a buzzer about 5 mph before a stall. i
t seemed to me that it was easy, relatively inexpensive, and effective. my
mkiii is noisy,,, so instead of a buzzer it could go to a bright flashing
light. simple, mechanical, easy to test..... why would something like t
hat not work?

There is a big push by the local fight safety organizations here in Alaska
to get pilots to install Angle of Attack (AOA) indicators. Every year we lo
se at least several pilots to low altitude stalls while circling big game a
nimals, in addition to other stalls causes. The military pilots, tell me th
at AOA was the way they were taught to fly since the configuration of their
planes were often changing in flight. I am not planning on installing rock
et pods on my wings, but to me the AOA sounds like a good idea for at least
a low time pilot, if not everyone. Are there any AOA equipped Kolb
=99s out there?

I decided to make a trip to the Steen's Mountain today since the sky was a
bit clearer than it has been for a while. For whatever reason I am
experiencing a bit of shake and vibration in the cameras that I don't
remember having before. Perhaps the scenry will make up for the
aggravation. I also noticed the difference in color between the Drift and
the Garmin. The Garmin is a bit sharper as well.
