That's the sort of info I was looking for. Any idea where I can find a
suitable overflow bottle? What flush do I need? The cap should be
available at NAPA.

--> Kitfox-List message posted by: "wingnut" <wingnut@spamarrest.com>
After further research on the internet, I finally found where I can download the operatin manual for the 912UL. For those of you that don't know (being optomistic here and assuming I wasn't the only one), you can download the operting manual for every rotax motor made at http://ww.rotax-aircraft-engines.com. It comes up in german but there's a link at the bottom for the english version.
If you've purchased a used, rotax powered airplane that didn't come with the manual,
then this download is a must. It answered all my questions and a few I didn't
know I needed to ask.
For the reccord, the manual has a nifty chart listing the reccomended power and
rpm settings for a 912UL with a variable pitch prop.
There's one bit that I picked up that seems too good to be true. According to the
manual, if I set the prop pitch to keep rpm to 5400, then there's no time limit
for full throttle operation. I'd been told that full throttle should be limited.
I wasn't sure about duration so I'd developed the habbit of pulling back
to 5000 after the cross wind turn. Consequently, it was taking me forever to
get to cruise altitude. If I'm interpreting the manual correctly, I can keep
full power all the way up. Even at 5200rpm, that's bettern than 1000fpm solo.
WOOHOO!
This is fantastic news. It's going to make for a whole different experience in
the climb.

Here's a link to the dealers. I ordered direct from
Evans as you only need a gallon of flush (IF you
already have EG in the system) and a gallon of
coolant. BTW, if you don't use up the whole gallon
of flush you can actually use it to add to the
coolant to top it off later. It's fully compatable
per Evans.

Thanks for that comment. I see no reason for the lower pressure cap, and
the Rotax SB doesn't require a lower pressure cap.

Best recommendation is the same formula that is recommended by Rotax. as it
has some ethelene glycol mixed into the propylene base that Evans uses. The
reason it for enhance the heat transfer properties. The info in the Rotax
bulletin and repeated on the Evans web site if I remember correctly. My
memory fails sorry.

The recommendation for 5200 RPM is static, i.e., while the plane is
not moving. When you accelerate to normal flight speeds the RPM will
rise to approximately red line RPM (5800).

That makes alot more sense. Unfortunately, my brakes are not strong enough to hold
the plane in position at full throttle so I resorted to tweeking the pitch
for 5200 on the upwind climb.
If 5200 static = 5800 at cruise, should I be seeing something like 5500 in the
climb?
Any feedback on my interpretation of the opertors manual? Can I realy set the pitch
for 5400 and leave the throttle in for the duration of the climb?

Thanks Paul,
When I get back in the US and can get around to it,
I`ll ask Evans too, before ordering. Each product
seems to have some advantages for a turbo soob running
at more than highway cruise power settings. Maybe the
Rotax mix will be best here too.

Yes you can..
Another area for manuals.. http://www.kodiakbs.com/tiintro.htm
Those with Rotax engines should also take a look at R.O.A.N.

Where are you located and what is the field elevation at you airport ? Full
power static RPM (on the brakes) will typically be about 200-500 rpm lower
then the desired max rpm for takeoff... setting the prop at the 5200 rpm
static should give you an approximate 5400 when climbing out but will push
up to 5500 - 5800 with full power level flight. It is referred to as
"UNLOADING" the prop.
Manifold pressure... You are correct.. 80% would be determined with MP.
Standard pressure is 29.92".. 80 % would be 24"... Rule of thumb.. you'll
loose an inch of manifold pressure per thousand feet... so in theory at 6000
feet full throttle will give you 80%.

Subject: Kitfox-List: Best RPM for takeoff with IVO prop and 912ULS
--> Kitfox-List message posted by: "wingnut" <wingnut@spamarrest.com>
Hello. I'm a new owner of a Model IV 1200 with a 912UL and an IVO prop. The
checklist that came with the airplane instructs me to set the prop pitch for
takeoff at 5200RPM. According to the published specs for the 912UL, peak
power is made at 5800 for two minutes then 5400 continuous. Shouldn't I set
the prop pitch for peak power?
Finding the best setting for cuise is another area of confusion. I'm
assuming that, since the RPM is adjustable with pitch that I need to look at
the manifold pressure to set for 80% power. Then it's just a matter of
tweaking the pitch for max speed right? So what manifold pressure constitues
80% power?

Great Rick,
This would probably make it so I can live with my
radiator scoop cooling capacity as is and only reduce
it in winter. (I am pushing it for cooling above 85 F
or so now, especially climbing or on a long taxi.)
Then I only only need to add the thermostat bypass to
my oil cooler to keep the temps up when cold.
Been running the coolant around 160 in the cool air
lately, but the oil doesn`t get hot enough then. If I
kept both at 210 F with Evans in it, that should work
well. Then I just have to watch the GB temps, which
seem to follow a little below the case temps.
BTW, what is the freezing point for Evans coolant?
Anyone found that yet?

The operator manual lists 75% power is obtained at 27.2" and 5000 RPM for the 912UL.
Could it be that power doesn't scale linearly with pressure? Am I missing
something?
The airplane is based at 34A (Laurens, SC). Elevation is 697 ft.
I'm hoping to get comfortable enough with short field operations one day to bring
it home to my 1000ft turf field.

The Rotax is RPM limited.. So, If you had a prop that would deliver 5800 RPM
at full power level flight.. Then following the 912 power curve 75% power
would be at approx 5000 RPM which would result in a 27.2" MP at sea level
pressure. I had some numbers somewhere from test flights.. but they were
with the 912S.. I'll see if I can find them...
Have a Safe New Year !!

Yep, If you already have the NSI unit , just get the full size rubber
made. The screw on cap will fit. If not check Summit racing. Evans has
the right flush. It removes any water that might be in the system. NAPP
is where I purchased mine. It wasn't the 3, think it was a 7.

That's the sort of info I was looking for. Any idea where I can find a
suitable overflow bottle? What flush do I need? The cap should be
available at NAPA. Deke

Is that you on page 41 of the January EAA Sport Pilot?
I figure it has to be. Your handle is almost a long as mine. Can't be many

Great resource, you got me thinking and looking around, another resource is
boat supply houses for boats throttle and shift cables. They currently have
some nice cables on E-Bay with lengths up to 40'

Wingnut,
The Rotax 912ul is rated 100% (5500 rpm) power for continous operation. It can
be run to 5800 rpm for 3 minutes of takeoff power. So if your engine is warm,
140 degrees F, then you can climb for 3 minutes at 5800 rpm and then reduce
the power to 5500 rpm and fly till the tanks run almost dry. You must reduce
power to 3500 for a minimum time to cool the engine (30 seconds or more if my
memory is correct) and then you may shut it off.
The Minimum recommended rpm is 5000 for continuous cruise.
You have an adjustable pitch prop so you should be able to get great performance.
Keep in mind that running high throttle settings and lowering the rpm is
harder on the engine than running high rpms at low throttle settings. That is,
5500 rpm and a low throttle setting is better than 5000 rpm with the throttle
more open.
Rotax also recommends that if you should run the engine above 5800 rpm that you
make a logbook entry....yep, that is all...just a logbook entry.
I do not always follow these recomendations to the letter. Last week I flew
formation with some overweight ultralights. They topped out at 65 mph. My climb
rpm was 4600 rpm I have a ground adjustable fixed pitch. Normally my long
descent rpm. Cruise was about 3900 rpm, my normal final approach rpm, and during
the low level pass over the airfield I had to land to give them room to get
ahead of me.

That makes alot more sense. Unfortunately, my brakes are not strong enough to hold
the plane in position at full throttle so I resorted to tweeking the pitch
for 5200 on the upwind climb.
If 5200 static = 5800 at cruise, should I be seeing something like 5500 in the
climb?
Any feedback on my interpretation of the opertors manual? Can I realy set the pitch
for 5400 and leave the throttle in for the duration of the climb?
