| Subject: | Re: 582 rotax in Wyoming? |
Hey Steve,
I don't know about a model IV, but my model III climbed great on a 582
3-1 C box and a 68" three bladed GSC prop. When I had it dialed in it
would climb loaded with me and another large individual and some gas to
at least 1050lbs (very gross weight) at ~500 fpm on a cold day. It
would exceed 100mph (Vne) level flight at full throttle and I often
cruised at 85. Solo, I climbed to over 13K feet using a HACman to
control EGT's. It was still climbing at ~300fpm but since I didn't have
oxygen I rounded off and went back down. It took about 20 minutes just
to get back down.
I would say that your model 2 should climb just fine with a 582. Note
that one of the guys on this list lengthened the exhaust manifold a
little from the Kitfox supplied one. Supposedly it is closer to the
stock Rotax configuration and he picked up some more power.
You will burn a great deal of gas and oil and it takes a lot of
maintenance to keep it running reliably but lack of power is not a
problem.
FWIW,

Steve,
Hopefully Lowell will reply. He had a friend who flew around
Idaho a lot with a 582 equipped IV. My own experience flying around
Utah and across the States is that you have limited climb capability.
My IV's gross ceiling is about 10.5k'; and it takes a long time to
get there. There are plenty of areas in Wyoming that you simply won't
visit with that limitation. (Note that I have a manual mixture
control as well.) Now weight factors in heavily, as in a much lighter
configuration, about 900 pounds, I can get to 12.5k' without too much
trouble. (Note that these are density altitudes, as well. Summer in
Wyoming may have a 10k' density altitude on the runway.)
The rate of climb is pretty limited too. Flying at about
1000 pounds I was unable to climb to even 9k' against a headwind
flying south along the 15 south of Salt Lake City. I had to make some
major detours looking for passes. Typically I flight plan for a
maximum altitude of 7.5k'. I seldom cruise above 9.5k', it just takes
too long to get there.

Sorry that your M760 isn't working. I've had one in my Kitfox for about
seven years now, no problems. Did you disconnect the PTT wire at the
connector? If that doesn't make it go away, see if they'll send you an
advance warranty replacement.

I know what you mean, Tom....lean to you means less oil to lube the
bottom end, eh? Unless things have changed since I last ran a 2-
stroke, all the bottom end stuff gets lubed via the oil, right? Or is
that what the oil injected engines do, is take care of the lubing so
the fuel can go oil-less?

Lynn, pretty much what you say about the lube is correct. The top end...piston
skirts and wrist pins/bearings...are also lubed with the two stroke oil. Premixed
or injected the oil serves the same purpose.
The fuel also cools the top of the pistons. A lean fuel/air mixture can burn a
hole in the top of the pistons or melt the outside of the top of the piston around
the rings and cause the pistons to seize to the cylinder walls.
The good book of Rotax says "Thou shalt not exceed EGT temperature of 1200 degrees
F in Thy two stroke engine".

I tried to go flying last week, but the aircraft wasn't making full power.
After having some friends help me this weekend, we found the problem was a small
2" piece of black rubber hose used to connect the header tank to the metal line
under the seat. I had removed all of the black mil spec hose (or what I thought
was all of it) when I purchased the plane because I had read the problems
on this forum.
I just had my tanks filled, but tested the fuel for alcohol and there isn't any
in it. So, something else about the new fuel mix caused the tube to swell.
Scary part is that the metal line and the nipple on the header tank must have
been close enough to prevent it from swelling completely shut, because after
5 minutes we looked at the hose and you couldn't blow through it. Had just enough
of a trickle that you could run the engine at idle/taxi all you wanted, and
about 30 seconds of full power in the float bowls. Good result in the end,
but just want to add another recommendation to get rid of ALL of the black rubber
fuel hoses even if they do have a MIL number on them.

Speaking of fuel line, I'm having a fuel smell in my cockpit (S5). I've
torn everything out trying to find a leak, but nothing anywhere including
the sight gauges. Not even a stain. I had rubber fuel lines (not Milspec)
from the wing tanks to the header and I noticed that they had a strong smell
of fuel on them so I changed them out with Super Stock hoses from Earl's
Performance. These lines have a poly inner lining, rubber center lining,
then outer silicone covering, yet the smell persists. The one thing I
haven't changed out is the 1/4 ID polyurethane vent line from the header to
the right side wing tank. I was recently told that in time they will give
off a strong fuel odor (mine do) and that I should change them also. Not a
big deal to do and I plan on it, but I thought I'd check with the list to
see if others experienced this problem and what they found was the culprit
as I might be missing something. I'm pretty sure it isn't the wing tanks as
the smell doesn't seem to be emanating from that area. All help
appreciated.

Yes, I did John. Thanks for the suggestion. However, I may pull it all

| Subject: | Microair M760 radios |
I had a similar issue with an Xcom 760 radio. The factory in Australia said
they had a known issue with some of the mother boards from a new
subcontractor. I found a us distributer and was able to exchange it but it
did take 2 weeks. Couple things to think about .
1. disconnect both mikes. Some radios can be triggered to transmit from a
short in the mike or the wire.
2 A radio is not required for flight if you have found a real airport with
out a tower.
P.S. towered airports are for bad pilots. Why else do they need someone
else telling them what to do.

Subject: Kitfox-List: Microair M760 radios
Hi guys
Anybody had problems with a Microair M760 radio? Mine is just two weeks
old from brand new but the red light keeps coming on indicating that it is
transmitting and after the prescribed 45 seconds the light starts flashing
to indicate a stuck PTT. Nothing will stop it doing this, not even
completely disconnecting the PTT switch. Nothing will work on the radio
when it is doing this but after a few minutes it just comes right for no
apparent reason and then works perfectly, until the next time. It could
be fine all day or it could do it again in ten minutes. The factory says
send it back to Australia but that means no flying for a month or more.
