| Subject: | Evans Coolant in the 912 series |
Serialize complete at 09/09/2005 10:00:32 AM
--> Kitfox-List message posted by: kitfoxjunky <kitfoxjunky@decisionlabs.com>
Read an interesting thread on the list a while ago about the pros and cons
of the Evans waterless coolant. One listee said he would rather use
conventional coolant...that way if he was on a cross country and needed to
top up the coolant he had a good chance of being able to obtain it...
Evans being less likely to come by. Sounded reasonable to me, and
although some of the techy benefits of reducing hot spots sounded
appealing, I never made the switch.
I was at a seminar a couple of weeks back and a gent from a certified
Rotax repair station giving a presentation on maintenance of the 912 made
a comment that struck home. He said that the Evans runs a zero pressure.
That is why there is a new cap for the reservoir. The standard 50/50
glycol mix runs at about 10 psi..and goes up with altitude. If you have a
leak in flight with the glycol, there is a good chance you will loose a
lot of the fluid, probably loose the engine. With the Evans, there is a
good chance you will make it down since the fluid will not rush out of the
system. My guess is that you will see the leak on the ground in your walk
around, as I know of no way you would detect it in the air unless it was
kicking up smoke...but still it sounded like a valid point. Enough to make
me make the switch.
That point may have come up in previous discussions and I missed it...but
thought it was worth revisiting. Any thoughts?

I didn't follow the past thread and didn't realize the Evans was "zero"
pressure. What kind of reservoir cap do you install? One that's vented?
Sounds like a good theory about loosing less coolant with a leak.

I know the cap is specified in the service bulletin put out by Rotax.
Yeah..the zero pressure was news to me too. If you think of it, that is a
big plus...considering the heads can melt off in seconds if the coolant
fails.

--> Kitfox-List message posted by: PWilson <pwmac@sisna.com>
Gary,
I have never seen a Rotax document that changed the pressure cap.
Maybe someone could refer me to the change. The mandatory bulletin
that added Evans coolant just said to put a sticker on the existing cap.
Somewhere in the past I thought I saw a Rotax document that revised
the cap pressure set point but cannot find that document
either. Need help, Thanks, Paul
PS, My cap is 0.9 Bar which is 13.2psi and I was going to add a
pressure gauge to monitor the pressure to notify me of a leak.
Of course the presenter made an erroneous comment about the pressure
going up with altitude. Fact: The cap maintains an constant pressure
above ambient which decreases with altitude. This means a leak would
be the same at sea level as it would be at a higher altitude because
the pressure differential would be the same.
The comment someone made about replacing Evans coolant while flying
cross country. Maybe if that were to happen the flight should not
continue until the leak was found. I believe many hot rod shops sell
Evans coolant. In any event a quick call to Evans would locate a
source locally or overnight to where you are.
Paul

| Subject: | Rotax 912 operators. Did you know about coil pickup gapping?? |
Serialize complete at 09/09/2005 04:42:16 PM
--> Kitfox-List message posted by: kitfoxjunky <kitfoxjunky@decisionlabs.com>
On the mag side of the engine there are several black coil pickups.
Depending upon the design of the pickup (there is an old and a new
design), there is a range for the gap between the pickup and the cam on
the part that rotates with the engine. The pickups are easily bent during
installation, and the gap should be checked or rough running will result.
You can simply bend it back with a screwdriver.
I was aware that carb synching, blade tracking and a few other things were
part of getting a smooth running engine, but that one was news to me.
Thought I would share it. I seem to remember that 16 thou was in the
range of both the old and new design.

What the trim assist does is replace the force you use with your hand to
hold the stick back with force from a spring. The spring does not put the
elevator in any different position than the pilot would without it. You are
just letting the spring do the work instead of your arm. So, NO elevator
range is lost at all!
Also, without flaps, the force from the spring is only enough to bring the
elevator to the neutral position. When flaps are added, the spring is
stretched and it applies more force to hold the elevator.

This subject needs to be side tracked ASAP. There is no such thing a
zero pressure liquid Evans included. The vapor pressure may be less
that a E Glycol mix but if you loose coolant the pressure will rise
until it stabilizes at the boiling point.
BTW, The Evans coolant specified by Rotax is NOT 100% Propoline
Glycol I think it has EG and other chemical in it to meed the Rotax
requirements.

Gary,
This was discussed a couple of weeks ago when I brought up the
subject. I was having problems getting my tach to read right. It was
recommended that a range of .016 to .020 should work. I also learned that if
your tach still doesn't read right, meaning the needle pigs all the way to
the right, you can wire in a 100 to 200 ohm resistor across the leads coming
from the pickup. I had to do this and my tach looks like it is reading
right. I plan on having it checked to make sure it is accurate.

I kept the carbheat box, but took the valve out and put an air filter on
each inlet. I figured it would breath easier. (I like the 2/300 rpm
comment below, but don't know if it is real.)
First flight was November last year, so I have almost a full year of
experience. - No icing.

Randy,
I can verify that the carb heat box does indeed rob you of 200-300 rpm
When I removed mine, I saw the increase immediately.
Also, if any of you have the old carb heat box installed, please make sure
that the box mounting bolts have castle nuts with cotter pins. DO NOT use
lock nuts, not even metal AN nuts, they can and mostly likely will
eventually come loose.
This is one of those things I really wish I hadn't learned the hard way.
Cliff
PS. this goes for any bolts on the carb heat box. Just examine the box and
imagine any bolt coming loose, where will it go? Yep, right inside your
engine!

| Subject: | Evans Coolant in the 912 series |
--> Kitfox-List message posted by: "Rick" <turboflyer@comcast.net>
I believe the cap I am using is a 7.5. I have had the Evans coolant in my
turbo EA-81 application for a big 75 hours now. I feel the benefits far out
weigh the need/chance for a remote refill. This is a long term benefit
analysis, so I am not prepared to give the engine tear down analysis yet.
The expansion rate is higher than regular coolant. One of the benefits of
that is the coolant acts as its own thermostat. When cold it flow slower
allowing warm up and when hot thins out to facilitate cooling. Work for me.

Gary,
I have never seen a Rotax document that changed the pressure cap.
Maybe someone could refer me to the change. The mandatory bulletin
that added Evans coolant just said to put a sticker on the existing cap.
Somewhere in the past I thought I saw a Rotax document that revised
the cap pressure set point but cannot find that document
either. Need help, Thanks, Paul
PS, My cap is 0.9 Bar which is 13.2psi and I was going to add a
pressure gauge to monitor the pressure to notify me of a leak.
Of course the presenter made an erroneous comment about the pressure
going up with altitude. Fact: The cap maintains an constant pressure
above ambient which decreases with altitude. This means a leak would
be the same at sea level as it would be at a higher altitude because
the pressure differential would be the same.
The comment someone made about replacing Evans coolant while flying
cross country. Maybe if that were to happen the flight should not
continue until the leak was found. I believe many hot rod shops sell
Evans coolant. In any event a quick call to Evans would locate a
source locally or overnight to where you are.

If I understand this. If I were at high density altitude and coming hot...oh
yea Kitfox hot, with the trim assist activated by adding flaps, then I might
not have as much elevator authority as I would have otherwise had by just
adjusting the elevator with the actuator ram. Is that right?

Wow - I took the 'Fox up tonight...It was NOTHING short of incredible -
there aren't words. I haven't installed the instrument lighting, but I went
up anyway with a flashlight, though I didn't end up using it. I could just
make out the white hands on the instruments, and I knew where they should be
- and I was able to keep altitude/airspeed very nicely.
I climbed up to two thousand feet and just cruised with the doors open,
enjoying the warm night air (a temp. inversion had already begun). A local
airport - Sanford, ME, had one of the runways lit up like a christmas tree,
complete with the "rabbit" for the ILS. Portsmouth, NH was gorgeous, and I
even saw some fireworks! If it weren't for my buddy waiting for me on the
ground, I would never have come down :)
I started my descent and just crossed the threshold on short final when the
runway lights went out. I fiddled with the handheld to turn them back on and
then went around for another shot. I watched the landing light hit the
pavement and made a greaser of a wheel-landing - absolutely perfect!
I'm still grinning ear-to-ear, two hours later! What a privilege!

| Subject: | Trim assist for the elevator |
--> Kitfox-List message posted by: "jdmcbean" <jdmcbean@cableone.net>
NO... The trim assist does not decrease elevator authority.. it gives you
more authority to hold up the elevator... I guess it may be named wrong..
maybe back pressure assist would be more appropriate, but trim assist it
is. It simply assists you in applying the back pressure required.
Without the trim assist... when on approach to landing with no flaps one can
very easily trim the aircraft for a hands off approach. However, introduce
flaps and then re-trim.. one runs out of trim for hands off at the same
given airspeed.. Therefore one needs to hold back pressure on the stick to
maintain the given airspeed. The more flaps used the more back pressure
required.
For example: Debra could trim our 7 for a 60 IAS approach no flaps hands off
just fine, but had a hard time holding the required back pressure for a 60
IAS approach with 1 notch of flaps and the aircraft trimmed. Now with the
trim assist (back pressure assist) she can get the aircraft trimmed hands
off for a 60 IAS with 2 notches of flaps.
Hope this makes sense...
Fly Safe !!
