| Subject: | Re: 582 running hot? |
I had a Mk 4 582 before my Mk 5 and when I bought it the engine (grey head) coolant
ran quite warm. Your EGT's seem fine if they max at 1150 and I wouldn't
be too concerned at those. Contrary to what many people believe, these will rise
with cooler ambient air so in the Summer you will find they are fine but might
creep up to 1200 in the Winter. Coarsening of the prop SHOULD help this
and I used to adjust my prop to the EGT's as the seasons changed and it worked
a treat for me. I aimed for 6200 static.
Regarding the coolant temps, I did the following (and in this order):
1. I reduced the coolant percentage to 75 water/25 coolant which made a bit of
difference (about 10 degrees).
2. I lowered the radiator and this did nothing.
3. I moved the radiator back 2 inches and this did nothing.
4. I then decided to buy the over-sized rad from Kitfox and the temps dropped
by 30 degrees and ran comfortably at 160 from there on.
I know it is an expensive option but it worked really well and I could return the
coolant back to the 50:50 ratio with no worries.

Depending on where you live, you can dilute your coolant to about 75/25. Ethylene
Glycol is an insulator, not a conductor. It is a double edge sword, however.
The lower ratio will boil sooner, but it cools better.
In a 2-stroke engine, the mixture cools the cylinders as well. if you're running
lean, it will run hotter. Richen it up a bit to cool it down. Also check your
oil flow; it may be a reduction in flow. Of course if your pre-mixing, you can
add a little bit more to the mix. otherwise, check your oiler to make sure
its working properly.

| Subject: | Re: fiberglass fuel tanks needed |
I have two new 6 gal fiberglass tanks for a M3 that I did not use. One is warped,
and I worked on making it fit. In the end, I splurged on the plastic tanks.
They were never installed in the plane.
Let em know if you're interested.

The "jam" nut they're referring to is the second nut on the shaft. The prop always
needs at least one. If you are pitching from neutral through -2, use the jam
nut. I use it anyway - better safe than sorry.
Think about it for a minute, and makes sense. If you pitch the blades a bit, the
tension of the inner torque rod keeps tension on the nut. If you don't torque
the rod, there wouldn't be any tension on the nut to keep it in place.
Clear as mud?

| Subject: | Re: cutting windshield |
I used to use a scroll saw to cut mine. It works ok, is fast, can easily accomodate
a guide for straight cuts. Then finish off with a belt sander or a router
for a rounded edge.
I bought one of those oscillating saws from Sears for a home project. On a whim,
I tried it on the Lexan for my windshield. With the saw attachment, it really
works great! You could fab a fence for dead-straight cuts, but the tool will
follow a line very well without it.

The holes mightbe there to allow bubbles to pass when "burping the system. I place

| Subject: | Re: Ivo fun with some questions |
Thanks Beemer...Mine came with only one Jam nut. I tighten it all the time now
and everything is doing fine. I figured, with certain pitch settings, that there
was enough force on the adjuster/cam arrangement to keep it in place, especially
if aerodynamic loads weren't too high. I guess I was more surprised that
IVO would advocate leaving ANY nut loose on such a dynamic system, whether
it was load bearing or not.
Anyway, it's always nice to hear someone else's opinion. Do you torque yours down
to any specific value?

I took off about a 1 1/2 degrees from my prop and ran it up to just short

takeoff roll, maybe 6100. In cruise at wide open throttle and level I saw
a higher RPM, 6400. So, at least the static versus cruise RPMs make more
sense
this time. I don't know why I twice have gotten a higher RPM right after
installation
test than later flight test. Different conditions of some type, but
not
Remember, ANY change in Density Altitude will change the perceived power
output from your engine. This goes for 2 stroke, 4 stroke, turboprop and
pure jet. Write down the temp and altitude when doing tests, then compare,
you will find what a difference it makes.

| Subject: | Losing rpm on takeoff |
Looking for ideas here. My test pilot says he is losing about 500 rpm
upon becoming airborne. Has low rpm all during climb and is doubtful of
full power on cruise. EGT's appear fine, although he was not riveted on
the gauge having a few other things to watch.
I checked fuel flow and the function of the vacuum fuel pump to be ok. I
also had a look at the plugs and they look a little dark but not wet and
certainly not lean.
I did a one minute run at full power on the ground with no loss of rpm,
it pulls a little over 6200 static, EGT's run up to around 1100 but drop
off quickly with only a little pull back on the throttle and normally
run around 1000-1025 on a Westach gauge.
Currently reviewing a my documentation for ideas. Right now I'm leaning
toward doubting the tach.
Engine has 82 hours and was recently checked out by a service center.

Dave, Your static RPM sounds in the right range 6000 t0 6300 IF your tach is
correct - Get a Tiny tach if you do not have one.
EGT gauge is only for reference not for actual temps but it might read accurate
- WHO KNOWS !! Plugs will tell you what is going on inside.
At cruise 5800 to 6000 RPM plugs should be med to light brown. MEd or darker is
too rich or too much pitch. You should be be using NGK BR8ES. If you do not
have the right plugs order some from Bob Robertson when you order the tiny tach
1-866-418-4164.
If your EGT are correct you should see 1100 to 1200 rpm in cruise no colder. Your
EGT are calibrated for 70 F right now the temps are about 20 to 30 F outside
do you are reading 50 F higher than it really is.
Cheers
Your needle clip should be in the 3 rd notch from the top but changing to the bottom
notch once temps are below 0 C ( 32 F) for the winter.

Sounds like the prop is pitched a little too coarse. Try backing off a degree
or two.

I'd doubt the tach too. My plane was doing almost the same thing as yours
and one day I had an ivo set for a go around and after an hour on the ground
firewalled the throttle for a takeoff. Imagine my surprise when the plane
leapt into the air and the tach spiralled up to the wrong side of seven
grand, make that the low side of 8 grand! I got a Tiny Tach and quickly
found my Westach read a consistent 20% too high.
I often wonder how I was ever able to get the plane into the air with a true
take off rpm of around 5400 rpm.
