Deke and Jim,
The person that bought all of NSI's EA81 inventory was Mykal Templeman who
now runs Stratus ([mjt@camano.net]). I got my diodes from Mouser, they are
NTE517 5kV made for microwave ovens. They are a bit pricey for diodes.

questions..
Deke,
I used a Dremel tool along with various other small tools to carefully
remove the potting compound and diodes. To test the diodes I took them to a
retired HP electrical engineer I had once built a house for and who became a
friend. He has a pretty complete lab at his house. As I remember due to
the size of the diodes it was difficult to fully test them. I obtained some
replacement diodes from a former NSI employee who I learned had purchased
NSI's inventory. I can't think of his name at this moment, but he builds
another well known EA81 aircraft conversion. I only replaced the diodes we
thought to be failed. You are correct in that they do fit tightly and I was
concerned that they might short out. I purchased the potting compound from
an electrical supply company. I think I still have the bottle at home and
will look for it along with my photos when I return from my current road
trip. I gave the unused diodes to the engine purchaser who took it all back
to Australia where he lives.
My work was successful and I ground ran the engine several times with no
problem after the repair--something I could not do before the repair.

Keep the tire pressure low in the trailer so as to soften the ride.
Chose a non-rainy day to tow. Drain all fuel, if any, from wing
tanks. Make sure you have the "front-spar-to-lower-fuselage" braces
in place. Keep weight off tail wheel by elevating tail slightly then
attaching braces from trailer up to the tubing that is welded into
the fuselage near the rear spring. This keeps the weight off the tail
spring.

Mike,
That's correct. It was Mr. Templeton I purchased them from.

| Subject: | FWF parts wanted for Rotax 912 |
Good evening,
I bought my FWF from someone who didn't finish his project and I've discovered
I'm missing some parts. Before I order them, I thought I'd check with the list
to see if anyone has any they would like to sell.
All parts needed for a Rotax 912.
Rectifier/regulator connector housing (I have the regulator, just need the black
connector) Rotax part number 965 335
New style oil tank dipstick (looks square vice round at top) Rotax part number
956 151
Coolant expansion tank, Rotax part number 922 312 or 922 317
CHT or oil temp sender (screw in type, come with engine), Rotax part number 965
530 (need 2)
throttle splitter package for dual carb
choke splitter package
oil cooler
Thanks,
Brent Bidus

| Subject: | Regarding the 582 weight.... |
The 582 is also a two cylinder and carries a PSRU. The radiators and
associated plumbing also have a weight penalty. For all that for 64 hp the
582 is pretty good bang for the buck.
As for oil being heavier... Doesn't oil float on water and isn't antifreeze
heavier than water?

<matronics@bob.brennan.name>
Hey Lynn - Call me stupid but the 582 is liquid cooled but a 2-stroker, and
the Jab is air-cooled and a 4-stroker, so the 582 "wet" has the weight of
the coolant and no oil and the Jab wet has the weight of the engine oil and
no coolant. I don't know what the liquid capacities are but doesn't that
kind of balance out? In fact I would think the oil is heavier?

Subject: Kitfox-List: Regarding the 582 weight....
I just happened to run across this on another group:
"The weight of the 582 plus liquids wound up being somewhat more than
the entire Jab installation (about three pounds) with no change in W/
B. I figure I lost a few pounds and gained 24 hp."
This was found on TeamKitfox (or whatever they call themselves), and
it was from a guy who pulled his 582 and installed a Jab 2200. I'm
not trying to sell Jabs, just trying to keep all our minds open.
Maybe the ENGINE doesn't weigh as much as a Jabiru, but you can't RUN
the engine without all the associated goodies. : )
