Hi Jim-
Paul Franz mentioned.....
Ultra Poly HVOS
High Visibility Orange with Silicone added
Crosslinked for enhanced abrasion resistance and lower
coefficient of friction.
....and this really sounds exciting to me. I've sent out emails
requesting pricing and hope to hear from them on Monday. Jeez, the
fact that it comes colored orange is a plus, as my plane is orange!
Pretty puny excuse for using it but it sounds like just the ticket
for skis. If this stuff is what they say it is, I may have to abandon
the idea of plywood bottoms with carbon fiber, or fiberglass coating,
etc. My present skis are UHMW, and I just bought HDPE for a test,
knowing that the UHMW was less draggy, but the HDPE was half the
price. For a test, I didn't care what the friction coefficient was, I
just wanted to test the design.

Thanks Paul-
I just looked at those sites and emailed them for more info. The HVOS

You're welcome! :}}
Did you see some of the blends with epoxy? You can then bond layers to it or bond
it
to a foam core. You might ask them about bonding to the HVOS.

I don't think at this point that I need to or want to bond anything

The ski bottoms are NOT stepped, they are flat. I was going to get pics for you
guys yesterday, but the hangar was locked up tight and the guy is on vacation

If your Federal skis don't have the hole in the pedestal at an angle then
they are made for an Ercoupe. I have seen several airplanes with 2 left or 2
right skis on them. Also left and rights put on backwards. On Federals the
tag is on the low or outside side of the ski pedestal. I have a set of the
Federal 1400's on my Champ. They are shorter and wider than the old 1500's.
I have had both and like the short wide ones better.

Are you sure the axle mount is not tilted, Noel? I have an author's
write-up for mounting Federal skis A-1500A through A-2000A, and in it
is the mention:
"How many ski fliers using Federal skis know that there is a right
and a left ski? I was always under the impression that the skis were
interchangeable from side to side. This is definitely not true!"
It goes on to say (and this is written on a drawing from Federal
Instructions):
"Inspect your ski pedestals carefully to determine the left and right
ski. The high side of the pedestal cross tube is always placed on the
inside."
In looking at the drawings of the Federal skis, Noel, there is
definitely a high and a low side, just like your skis appear to have.
I'm not saying that yours do, but it might be worth looking at again.
After all, there might be some compensation for camber built into
your skis....Federal seems to have done that in the ski that these
instructions pertain to. Another caption reads:
"To compensate for the camber of the landing gear, Federal Skis are
made Left and Right. The high side of the pedestal cross tube must be
placed on the inside of the gear."
If your axle aren't tilted, it appears that the ski was built so that
a tilted axle insert could be done.
Noel: I really like the reversing inserts! That's a neat idea.
Definitely want those puppies off, when you go forward!
The whole email came into me at 170KB, Noel, and thanks for shooting
them.

There was just a knock on my door and it was the UPS guy with all my
new ski material...chrome-moly, cables, shock cord, thimbles,
shackles, etc. Even got a book on operating a plane on floats and
skis. Man, I ordered that stuff (Aircraft Spruce) on Monday, and it's

Thanks, for the photos, Ron, absolutely clear....brings back the days

Interesting...thanks for the input, "Zim". This is good stuff to
know...I wonder why the Federal people didn't mark the skis left and
right. I had a Fed 1500 at home here and I cleaned off the data plate
(which was at the rear of the ski) and could not determine any L or R
designation. Maybe I didn't know what I was looking for....OR they
were for a 'coupe, like you said. ....no, these were slanted, so that
can't be.

Subject: | 582 RPM question. |
Just a quick question about 582 RPMs. I ran the engine up today, keeping it lubed
up. My instructor and I plan to start flying the first or second weekend
of Jan. weather permitting.
After warm up, I ran the power up the full throttle for 30 seconds or so. The
tach. is labeled on the glass with a green and red arc sticker. It looks like
it was hand put on by the last owner. Anyway, red starts about 6200. At full
throttle, on the ground, it was making about 5800-5900. The engine ran well,
and did not hiccup at all.
I know that in cruise it will unload a little, and have a little higher RPM over
a static test, but I was just wondering if those RPMs were OK, or off the mark,
seeing that the max of the 582 is somewhere around 6800.
The setup is a 582 gray head, with dual Bing 54 carbs., C gearbox, (not sure of
ratio), and a 3 blade Warp Drive. Running about full rich, as the on EGT was
around 1150+. Cool 25*F, at 1700MSL.
Does the pitch of the prop make much of a difference in RPM?

Yes. A prop, depending on the pitch, can produce full throttle static RPM
well below redline, regardless of the engine it is mounted on.

Subject: | 582 RPM question. |
there can be a lot of debate .... I finally had a long talk with the
folks at Lockwood and my wot at climb was 6200 and wot on ground was
about 6000 ... they said I was giving up a lot of power and in fact
harder on the engine.... they told at least 6600 wot during best rate
of climb ( 55 mph) 6800 is better. Well I took a bit of pitch out
and get 6600 or a bit more wot at 55 and it definitely better. TT on
that engine 438 hrs. IVO prop 3 blade
I think some folks think lower rpm is kinder to a 2 stroke when in fact
it may not be ..let her run like its tuned to enjoy!

Subject: | Main Jets on 582 |
Have a quick question. I am running a EGT of about 1000 with my 165 jets that we
included with the KF3/Rotax 582 I just purchased. The previous owner also provided
a spare set of 160 mail jets. It looks likes from the Rotax documentation
that given the TEMP and ALT here this time of year the 160 should work better.
KF is a little 'piggy/running rich' now.
Question 1) Will going from a 165 to a 160 likely lean the engine out some so I
can get a little performance out of it and get closer to a 1100 EGT?
Question 2) When I remove the lower bowl what parts will drop out? 2 floats, fuel
stabilizer, float arm? Can I just them replace the 165 jets with the 160 jets
while the carb is still on the aircraft? Will I likely have to tweak the carbs?
This looks like a 1 minute job. Any potential problems/issues?
thanks..jack

Maybe the 6200 is real 6800 calibrated RPM!?
