Dear Listers,
The percentage of people making a Contribution to support the Lists this year is
currently lagging behind last year by approximately 21%! I'm hoping that everyone
is just waiting until the last minute to show their support... ;-)
Please remember that it is solely your direct Contributions that keep these Lists
up and running and most importantly - AD FREE! If the members don't want to
support the Lists directly, then I will likely have to start adding advertisements
to offset the costs of running the Lists. But I *really* don't want to
have to start doing that. I really like the non-commercial atmosphere here and
I think that a lot of the members appreciate that too.
Please take a moment to make a Contribution today in support of the continued ad-free
operation of all these Lists:
http://www.matronics.com/contribution
I want to send out a word of appreciation to all of the members that have already
made their generous Contribution to support the Lists! Thank you!

| Subject: | Re: Kitfox Engine - 2 Stroke VS 4 Stroke (Mid-range RPMs) |
Guys,
I have a Kitfox-II with the older 582. Total time on the engine is
about 200 hours. Most of the time I'm flying around at 5,000 to 5,200
RPM. Descents are done at 4,000 to 4,500 RPM enroute to the airport. I
cruise about 1,000 to 1,500 AGL. EGTs are always good.
Take off rpm is around 6,500 rpm.
Might I be exposed flying and descending at these mid-range RPMs?

not if your EGTs are in the green. You need to load the engine to keep the EGTs
down, one feature I really like about the IFA. I just bump in more pitch on
a long decent so the engine stays loaded.
If your EGTs are going up, drop the needles one clip and see if it helps.
I have the Arctic Sparrow mixture control, so I can twist the needles out a turn
or 2 on a long decent if need be.

Matt,
I belong to several snowmobile forums. All have the option of being a CM or Contributing
member. Most are 15-20 bucks a year. The benefits are that you get
more attachment space etc. Non CM's have limited space to post pics etc.
Just something to think about, as most guys are willing to kick in just to say
they help the site out, and to have their name in green when they log on to the
forum. May be worth looking at for you.

I used to run Premium gas in my 100 HP 912 but now in our area it all
contains ethanol except 1 station that has regular gas without it.I do
not really want to use gas that has it ! ! and per Rotax,the octane
rating of regular is too low.
Is the only answer now,you will have to use 100LL ?
Thanks,
George

Your analysis is accurate as far as it goes, but there is a
potentially significant difference between the two cases. In flight
the prop is "loaded"; meaning it is "mechanically" connected to a
fast moving air stream. It will resist any variation from it's
equilibrium rpm. When you're on the ground there is no load at idle
and little load at, say, 3000 rpm. I have never quantified the
difference so I avoid testing in that regime.

You are anyway. With the 3:1 gearing and the wimpy Warp drive blades
you'd have to loose all compression to turn the engine with the prop.
I think there are several in the list who have shut down in flight
and discovered this.

I think I can do around 400-500 fpm, but it's a cruise speed descent
and slow relative to my fly-mates.

It is, but not by much. The main variation is that the oil injection
reduces dramatically at idle. I've never seen the curve, but that's
what I've been told.

There was one that Don Pearsall cooked up. He had it posted on his website, might
be
able to find it there still.

You might google for something like "aircraft weight and balance spreadsheet".

Pat,
The glass will stay in place if it is wetted out properly (read not too much resin).
No tape or other means to hold it in place on the underside of the wing
is necessary. And, yes they must be removed to fold the wings. I don't ever
fold my wings but there are only 3 fasteners that need to be removed if I did.
And yes, Lynn is correct...breathing protection is in order but only for the sanding
and painting phases if you use epoxy resin. If you use polyester or vinylester
resin, well that is a hole different ballgame.

Whoops. You overshot. You got it down to 8kb but it's too
small to see. Re-size to 1024 x 768 pixels and set your JPEG
compression to 15 and you should get a file size just under 100k,
which should be fine for a single picture. If you want to send a
bunch of pictures, follow the instructions on
http://www.matronics.com/photoshare/kitfox-list.html#Top and post a
notice of the addition on the list.

| Subject: | Plexiglass Scratch Repair... |
Dear Listers,
During the fitting of the Plexiglass canopy on my RV-8, I managed to put some pretty
disheartening scratches in the windscreen section. You can see from the
pictures that they looked pretty bad. A call to Van's revealed that a replacement
canopy would be $640 + $250 shipping to California! Ack.
So what to do... A bit of surfing and I found this "Scratch Off" windshield repair
kit for $35 on the Aircraft Spruce web site:
http://www.aircraftspruce.com/catalog/cspages/scratchoff.php
Frankly, it just seemed too good to be true. Nothing for $35 could be that "magic"
I thought, but what did I have to lose at this point....
Well, the kit arrived yesterday and I decided to give it a try tonight. In a word:
WOW! In about 2 hours the windscreen looked as good as new - no kidding
- AS GOOD AS NEW! The pictures really don't do the repair justice. It looks
better in person.
There are basically two sponges in the kit with four decreasingly porous pastes.
You just put some of the first paste on the sponge and buff it in with a drill
at 1200 RPM or less. Then you wash everything down good including the sponge
and windshield with warm water. Then you use the next finer paste and repeat
the process. Etc, etc, until you've used the 4th paste that is kind of like
car wax.
Frankly, the scratches were gone after the first application of paste - I started
at #2 based on the instructions and the "observed severity" of the scratch
depth.
So, the bottom line is, if you've got scuffs or mild scratches in your Plexiglass
buy this repair kit. It works!
