Lockwood sells an oil cooler thermostat, presumably suitable for Rotax
912S.
- Anyone with good experience using this to keep oil temp acceptably
high (problem at my latitudes)?
- Does it come with good installation instructions?
- What other fittings are required to connect it to standard Europa oil
system?
- Any good alternatives?
Thanks!

I tried the Mocal OT/1 oil thermostat as per an approved
PFA mod, which required drilling out the four oil
entrances and exits. I think this messed up the system
inside. It does not keep the temperature up in cold
weather. It needs "close off the air through the
radiators" baffling also.
I have bought one of these Lockwood thermostats, made by
Perma-Cool. It has good documentation but has a very
strange sentence in it.
"Under severely extreme colling conditions it may be
possible to overcool the oil even with the thermostat in
place. This can be caused by the cooled oil moving through
the thermostat and creating a false reading from the
thermostat actuator".
This I do not make any sense of, especially with the
following sentence :
"In these circumstances, it is recommended that the "C2"
(return from the cooler) be plugged and that the return
line from the oil cooler be connected via a T fitting in
the line that runs between "E2" and the oil pump."
I have asked Perma-Cool twice to explain these words and
neither time did the answer make sense to me.
However if it does make sense to someone I would be
interested to hear !
In the case of the unaltered Mocal thermostat the oil path
through the cooler is blocked by its diaphragm when the
oil is cool. In the Lockwood one it isn't with maybe 10%
oil going through the cooler anyway. I can't however see
how any "overcooling" would be fixed by using the T piece
which avoids the cold oil going through the thermostat.
In short some (adjustable) baffling to reduce to almost
zero the air flow through the radiators in the cruise is
working for me ! (With the Mocal radiator) - I haven't
tried the Lockwood one yet)
I could scan the three pages of instructions and send them
to you if you wished.

Hi Svein
I know that our Scandinavian friend, Stefan hase mounted an oil
thermostat on his '914, and it seems to work all right.
You can get in touch with him on ingemarsson.s@telia.com

The Rotax dealers are now selling oil thermostats for the Rotax engines.
One should be aware that using an oil thermostat involves taking in
more cooling air than necessary, and diverting oil from the oil
cooler when not in the warmest conditions.
In addition to the extra weight, permanently taking in more air means
flying with the maximum possible cooling drag for the entire life of the
aircraft.
Dyn'Aero went this way for their 914 MCR glider tow : at towing speeds
drag is not really a problem, and repeated quick descents to land may
lead to overcooling.
If performance is key, it is simpler, lighter, and safer to use a
properly designed cowl flap. Less cooling air into the radiators means
less drag. This is what I chose for our four-seater project :
http://contrails.free.fr/tunnel.php
http://contrails.free.fr/engine_aerodyn_radia.php
Reducing drag is really worth some consideration with a clean aircraft.

Gilles

Roll then spray everything to give a uniform base for successive painting. Also
you want to be able to sand everything the same and not worry about specific
areas of the plane.

Brad,
Sand the gel coat slightly befor applying Smooth Prime - it will stick
better. After applying Smooth Prime everywhere, you will see that the gel
coat surface is far from perfect. "Moutains" and "valleys" show up, if you
cover the first coats of Smooth Prime with a black powder (3M has a perfect
product) and then sand the surface.

Alfred

Anybody interested in a gallon of pre-prime sealer. I've got a gallon
with hardener, which is not being used as I've handed the finishing over
to the pro's. A few quid and UK postage if anyone's interested, contact
me off forum.

Svein,
I bought the oil thermostat in Germany by the Rotax dealer Franz. The
system is quiet simple and the instructions for installation are clear.
You neet to ask for the connections you want. You can find all this on
the net. Franz Aircraft de. search under Zubeh=F6r =F6lthermostat.
Best regards,
Karel Vranken.

Gilles,
I can not imagine that the presence of an oilthermostat changes the flow of
the cooling air trough the radiators. What do you really mean by taking in
more air permanently?

Of course not.

Using a thermostat : change oil flow through the radiator, not air flow
- Take in enough air to cool on the "worst case conditions", say
ISA+23C and take-off power. This is a great amount of air.
- Continuously flow it through the radiator. And so incur highest
cooling drag permanently.
- When you need less cooling (cruise, descent, cold day, etc.), prevent
the oil from getting into the radiator. But still flow as much air
through the radiator.
- Add extra plumbing and obstruction in the oil circuit.
Using a cowl flap : change airflow through radiator, not oil flow
- Take in just enough air to cool the engine
- Take in much air when on take-off on a hot day (highest cooling drag)
- Take in less air during cruise (lower cooling drag)
- Take in still less on a cold day or on descent (lowest possible
cooling drag)
- No disturbance in the oil circuit
That's why the Mosquito and Mustang were so fast. Works great for us.
Hope this helps,
Best regards,
Gilles
