...My Rotax 503 makes a claimed 52 HP @ about 6,500 RPM.....
I've seen folks calling the 503 DCDI engine a 52 hp engine countless
times but none of the Rotax engine publications I've seen rate it at
more than 49.6 hp (37kw).
Anyone have any idea where this "52" comes from?

I've seen this as the claimed HP for the free-air cooled version. I.e. 2 less HP
that would otherwise be used to drive the cooling fan.

That makes sense but have you ever seen a 503 DCDI engine without fan cooling?
I've never seen one.

Another great book for the icy Indy days is:
Inside the Sky: A Meditation on Flight by William Langewiesche. It is a great
insight into Mother Natures wrath and flying in her vengeance.
Amazon has it for $5.00--well worth it. I have probably read it 5 times.

Yeah I've seen this on the Phantom. It requires replacing the fan housing with
the one that doesn't have the fan on it and a free-air scoop in place of the regular
cooling shroud.
The cooling is simply accomplished by ram-air from the prop and relative wind.
I believe the replacement housing is a rotax option, but the cooling shroud is
a 3rd-party deal....

I believe this must be where I am getting lost. I see that venturi vacuum is
dependent upon throttle opening and engine rpm plus carburetor up stream
losses and/or conditions. Assuming engine timing is correct and
mechanically sound and with no change in propeller pitch, what am I missing
here?
The raising carburetor inlet pressure 4.73 inches of water represents
lowering the altitude by less than 500 feet.

Hi All,
Another great one is "Hammers of the Gods" by Martin Caidin, about
the transition days from props to jets by the airlines. Documents the
deadly mistakes brought on by ego, ignorance and chutzpah. Caidin has
written many books on warbirds, had restored a Junkers JU-52 3-engine
transport which is the one (IIRC) which appears in "Battle of Britain" circa
1968. Quite a character, looked like a Hell's Angel.

I haven't read any good books lately, but I have been doing some
thinking on my ethanol experience. First Kudos to Richard Pike for his
idea on how to make a usable cheap gascolator. Quite frankly it saved me
from a very interesting experience. I would have made the runway if the
engine had quit, but my laundry condition would have gotten me some flak
from the missus.
My observation is that the problem was caused by the ethanol breaking up
the residue in my tank from 11 years of using two stroke oil. I know
that many of you haven't been flying because of the weather, and may
have missed out on using ethanol yet. If that is the case, I would
suggest that either you soak your tanks in the stuff with the idea of
using it to clean them, dumping the stuff afterwards, or buying new
tanks to use with it. Might be a good time to invest in the new 6 gallon
tanks from TNK. I bet they could use the business.

After I finished my observations about the use of ethanol, I stuck my
head out the door to find that the temps had risen to 47 degrees and
there was no wind, at least on the ground anyway, so I got my flying
suit on and rolled Dart out of the hanger.
If you remember I was interested to see what difference if any flying at
80 percent power would be compared to max cruise of 5800 rpm. I flew the
same course that I did yesterday, under fairly close conditions. There
was still a head wind component of about 10 mph. I saw GPS speeds of 63
MPH on the trip up to 73 across the top of the triangle that I was
flying to 84 MPH on the down wind side. I flew the course in 24 minutes
compared to 30 yesterday. I burned just a smidge less gas doing it. 1.5
gallons. Not sure why this happens to me, Roger Hankins with a Firestar
I says that he can save gas by throttling back, but I never could even
with the 503. The fuel burn is always the same. I guess it just means
that I am polluting the world less or at least no more,by flying faster.
I can live with that.
Oh, this time I took my MP3 player with me and stuck the buds in my ears
under the headset. (Sig 45 ) to get some idea of how loud I would need
to turn them up to be able to hear it. I am happy to admit that the
volume was only a little more than I would have turned them on the
ground.

Yes, Russ, as a matter of fact, it is worth mentioning. Thanks.
Since good ol' Ernest seems to be of significant interest to a few, I thought I'd
pass this little trivia along.
Ernest Gann, and his wife, purchased a 1961 green and white Cessna 310 (new).
Along the sides of the plane, near the cockpit, was the name "Noon Balloon".
Evidently Ernest liked sleeping in quite late, and was in fact, known for showing
up for morning appointments around noon, hence the name Noon Balloon.
He, and his wife, often flew this 310 around the world, and it played a part
in his adventures and stories.
Around 1993, a good flying buddy of mine, Sturl Brunnel, bought Gann's Cessna
310, and parked it next to my first Cessna 172 on the ramp of our local airport,
O45 (Nut Tree Airport, Vacaville, CA). I saw one day that Sturl had sold
the plane, and told me some guy living in Florida bought it.
I have flown in the Noon Balloon two times. A bunch of us Vacaville pilots used
to fly our planes to our near-by airports and get a burger. I hitched a ride
with Sturl a couple of times.
A few days ago, I did an Internet search to see what happened to the "Noon Balloon",
and there an article about a guy that now has it in the back of his hangar,
with plans to make it the "finest 310 in the world", he says. I saw that
he was located in Florida.
Best regards,
Mike Welch

Glad that problem got taken care of. I feel much better now, even though I
just got home from the University of Alabama Birmingham School of Dentistry
where I was used a dental dummy for students all afternoon long.
Does anyone know where I could get a Ernest Kellogg Gann sticker to put on
my Kolb? I have some new holes that needed covering.
Nothing to look forward to at hauck's holler but freezing temps. Looking
for 18F Thursday morning. That would freeze up my Chilli Vest.
I have a new DRE6000 head set that I have not had the chance to fly with. I
have worn them around the house beating on stuff to see how they work on the
ground. May have to pull out the thermal underwear and hit the sky tomorrow
if it is not too windy.

Larry,
Those are really good #'s on your Firestar. If I see an 84 mph ground speed on
the GPS and do a 180 turn, it will drop to somewhere around 30 mph. I've never
done better than average maybe a 53-57 mph IAS in mine.
If you get a chance, post some more photos of the completed installation for us.

Since the list is kinda' quiet, I will post some of my speeds [calm air, gps
verified].
5600 rpm- 65 mph
6500 rpm [wot]- 81 mph
Except for a local FS II with 582, my speeds seem a good bit higher than
other FS II's around here. I also outclimb them.
I believe it's because of my setup; that being a "C" box, 3.47:1. & 68" 3
blade Kiev prop.
Oh, & maybe the VG's have something to do with it [hehehe].
