Jack,
Thanks for the math. Looks like the math jibes well with my experience and that
of others who have used this technique.

Also just FYI, I saw this 'new' prop at the AERO 2010 expo in Friedrichshafen in
Southern Germany last month. It's called the QD2, a four bladed prop with a
difference. That being that the two sets of two blades are both angularly and
axially offset and that apparently reduces the noise signature and they also claim
some performance improvements too. It's currently being test flown on a
trike.
See this site. http://www.e-props.fr/EP_RD.html Info is about 2/3rds down the page.

Subject: | In-flight Electric Adjustable IvoProp |
Mrs. Michelle Cole (I really know you're Vic G. he he)=2C
Thanks for the feedback regarding your IvoProp. I am glad to hear you do
n't fiddle with it much. That's one of the things I did NOT want to do (ad
just it much). I'd be happy if I could just set it...and forget it.
I think I'll still build the circuit=2C tho. With my very limited experi
ence with adj. props=2C I think knowing roughly where the pitch is will be
better than nothing (at least for me).
My Ivo is already cut down to a 70" diameter. I bought it that way.
I second what Bro Pike said. How about a full run-down on your engine...
.performance=2C numbers=2C noise levels=2C as much as you can fill in the b
lanks.
Regarding GEO engines=2C and their performance=3B it shouldn't be too mu
ch longer before I can fire mine up again. I had it 100% complete and runn
ing at one time=2C prior to installing the turbo=2C but then decided to add
my own turbocharger and hi-po cam.
Adding a turbo should put the power around a Rotax 912=2C maybe more...ma
ybe less. I won't know exactly=2C until I can measure thrust and other stu
ff. We'll see.......
BTW=2C my installation includes a host of gauges that monitor all the cri
tical things to watch for=2C i.e. boost gauge=2C EGT=2C AFR=2C Manifold Pre
ssure=2C etc. To install my turbo package (turbo=2C gauges=2C new muffler
=2C cam=2C etc.)=2C I have spent a total of around $1500. Add this to my e
ngine and prop costs of $6500 and I have a grand total cost of $8000 for ev
erything.

To your knowledge has this inspector cited any aircraft in your locale for noncompliance
with Part 103?
Let me address this to everyone; Has ANY of us, in our local area, been aware of
anyone being cited for noncompliance? I'm not interested in some newbie trying
to fly a two-place trainer as an UL, but planes that look mostly UL-like. Maybe
they are a tad heavy, or don't have the stall characteristics, etc.
I really don't hear about much of that happening except after a crash or something
and I'm curious.

GeoB,
Not to my knowledge in my area, but my knowledge is incomplete. Lack of enforcement
of the rules is likely due to insufficient manpower. However, the larger
fly-ins tend to attract the FAA folks so it seems to me the risk of getting cited
at one of these functions is higher than at your home airport during normal
ops.

About all that I can add is that Jeron Smith at Raven

I've heard of nothing local.
I've heard of two, elsewhere. One is a story floating around on the
internet, a guy flying a 2 place which he was in the middle of the ELSA
transition but hadn't received the paperwork yet, and an FAA guy who was on
the field to look at an air charter operation, but they didn't
show. Wasn't cited, just told not to fly it again until it was legal.
The other one was the guy who recently wrote an article in Ultraflight
magazine, claiming he'd been ramp checked five times with his PPC. The
story sounded far fetched to me.
The real risk is if you piss somebody off, or have an emergency landing,
and they decide to investigate. I don't think I'd want to fly an
overweight UL at Sun-N-Fun or Oshkosh, though...

Hi Jean,
Homer had a deal with Zodiac (the soft boat company) in the early 80s. They appreciated
the folding feature which parallels their de-flatable boats for easy
storage, shipping, &c. One of Homer's original reasons to design folding planes
was that he saw boating take-off when outboards came along, because allowed
the user to trailer home and store for little or no money.
Might this plane have been made by Zodiac?
Cheers,
Dave

Subject: | Re: Angle of Bank vs Stall Speed/Approach Technique |
David,
<< 'level approach' technique, you throw away all your safety margins >>
Agree, mostly, with all your points. Didn't say this was safe, didn't say I
like doing it. Said, sorta, this approach was commonly used in Alaska for
very short strips. For example, "Little Mount Susitna International" was on
top of the 2nd ridge across Cook Inlet. It was marked with a Clorox bleach
bottle nailed on the left side at the north end. North of the bottle was a
"rapid" decent. To the south the ground actually sloped down and after 100
feet was covered with hummocks. In other words, you had better touch down
very close to the Clorox so you could be slowed down before the big jolts
began.
But as you note, we were a lot younger then.
