Hi!Roger
No. Not that I could tell. Maximum 5 minutes and the coolant is too hot
to make a dash for it! I'm resigned to accept that at present, since
when flying it's fine. I get words of advice that after 10 to 50 hours
it runs cooler anyway.
I tried the half choke setting in flight yesterday and it made no
difference to coolant temps. I thought running richer would have had a
dramatic effect since the guys with a mixture facility can control their
burn really well.

Bob Harrison. G-PTAG

Hi Bob,
So changing the throttle setting a little higher or lower did not help

Hi Bob
"I tried the half choke setting in flight"
I meant for you to try 1/2 to full choke on ground to try and cool things
down!
Actual it is not a choke but an enrichening circuit. It does nothing much
/ above idle to richen things up! Thus your inflight test is exact as I
would suspect.
Giveratry on ground and please report.
How does full course and 2500 (also try 3000 and 3500) RPM do (angled into
wind) to help cool?

Perhaps you should open up the 'gills' in the top fairing, as you know I do
not have any overheating problem using 50/50. It can't make the situation

Roger:
I've had my 912 UL flying (Allegro 2000) for a little over two months now.
After two years of building the Allegro 2000 it is indeed joy to be in it
with the Rotax`912. The engine purrrr's like a kitten! In fact most pilots
at our small field (N92) want me to put a horn on the plane so they will
know when I am on the ground, as well as when I am in the air. The past two
years of sharing info on this engine has helped me immensely. I could not be
more pleased with it. Lets keep on sharing our experiences and knowledge.
Thanks for all you have shared.

Hi Rocky and Denise,
I glad to hear and see people are out enjoying life and flying both. You
will like the 912 for many years to come.
I'm also happy to see that all of us are sharing ideas, education and issues
here on the forum. I think it makes everyones life easier and more fun.
We don't have to share problems we can share our fun and trips, too.

Can you send a couple of pictures of your installation to me? What I'm
looking for right now is pictures of how the engine is mounted and
possibly
how you mounted the oil reservoir. If you have any could you post them
to
the list or directly to me at noelloveys@yahoo.ca

Hi there,
I'm flying a Zodiac 601 HDS with Rotax 912 with the water rad unerneath the cowling
(original Rotax rad). Depending on the OAT the water temps start to climb
to 220 F over a period of 10 minutes or so. During climb out I typically see
210 F. In cruise, the water temps drop to 140 F. CHT temperature on the other
hand does stay pretty stable at around 100 F (it's a bit higher, since the sensor
is not properly calibrated).
Also, a few weeks ago I had an incident with the Rotax: one of the cooling hoses
from the rad to the pump burst open and I lost all coolant fluid in flight.
Luckily, I was right over the airpoirt and down at the ground within 4 minutes.
During that time, the CHT temps didn't go up despite lack of cooling fluid.
Also, the water pump was not damaged due to lack of fluid. Pretty good engine....

Can you give us more detail about your setup ?
Where and how do you measure water temp ? Radiator exit, radiator entry,
etc...?
Witch of the two CHT probes are you using, front, rear ? 100 F is
really not a working temperature for the the cylinder heads. You already
read that in a hangar on a hot day...
Something must be wrong....

I am not entirely sure. what caused the hose to burst. It was the hose from the
water rad to an aluminum tube and from there from another hose to the pump. The
hose did burst lengthwise over a length of approx 12".
It looked like it started at the aluminum tubing, so I suspect the edge of the
aluminum tube was too sharp (although I couldn't feel any burrs). The hose was
not near the exhaust or any other hot items.

I agree that 100F sounds way off. It has to be higher than that if the engine is
running especially this time of year.

Hey Thilo, your description of your installation is similar to mine. Q.
Is the aluminum tube something you made or was it provided in your FWF
kit if it was a kit, my tube was pre-bent by the kit manufacturer. the
hose from the Rad to the aluminum tube is a 1" ID, 4" L wire reinforced
gates high pressure hose and from the Al tube to the water pump fitting
same type hose about 10 " long, the Aluminum tube is secured at each end
by two Adel clamps to the engine mount. I guess that was real good info
you provided the list. I often thought about coolant failure and what
catastrophic event would occur, like a Timex watch "Takes a licking, and
keeps on ticking"
Above all Thilo thank the Almighty all went well for you, Cheers
RJ
