A word of warning to those in the UK. The PFA wouldn't allow me to put such
a switch in the same line as the pitot in case it interferred with the ASI (if
the diaphram in the switch broke). Said I had to put in a separate pitot
head.

Troy,
What about the ones used in the Factory stall warner - that's very accurate
and sensitive. You may need one that worked in the opposite sense, but I'm
sure that'll exist, too.

Why not use an AOA for that purpose? It serves many different functions along
with correcting for all weights and conditions. Several of our system are
flying on Europas.
The pressure differences between 55 Kt and 75 Kt are extremely small, we are
working with pressure transducers on a Data Acquisition systems for test
flying prototype aircraft.

OK, I am now officially confused. Mogas, Avgas, RON, MON, oil changes at
50hrs or 25hrs with Avgas? According to my Rotax maintenance manual, oil
changes are required at 100hr intervals. What am I missing.
regards,
Mike

Mike, my practical "in a nutshell" advise would be to use the highest octane
rated Mogas you can buy, which is usually 93 octane. If you can't get
Mogas, then use 100LL. This advise goes for any Rotax engine, i.e.: 912,
912S or 914. As to oil and filter changes you can safely go to 100 hours if
you use exclusively Mogas, but since it's cheap I usually change mine around
50 hours. If you use 100LL exclusively I'd change my oil closer to every 50
hours since the lead in the gas will find it's way into the oil. This
advise is based on 6 years of flying with my trigear 914.
A word of caution to 914 users. The exclusive use of 100LL fuel WILL sooner
or later cause "sticking" of the turbo wastegate butterfly valve. When this
happens, you will not have a flyable airplane. The solution is to regularly
spray the wastegate valve with a penetrating spray. In the US I have found
a product called "Blaster" works miracles. Also, you can add TCP additive
to your fuel, but it's hard to find. Exclusive use of 100LL also will cause
your fuel filters to clog quicker, and your spark plugs to foul quicker.

Yesterday I was talking with a specialist of the German Rotax dealer
Franz about their oil and coolant thermostats. Their experience with
Rotax 912 engines operated in the nothern parts of Europe: It often
lasts a long time until the oil temperature is at a level permitting the
application of full take-off power, and a lot of engines are operated at
oil temperature levels permanently too low - with all the bad side
effects. He highly recommends the oil thermostat. Only if the coolant
temperatures - despite an installed oil thermostat - are always too low,
a coolant thermostat is recommended. Their oil thermostat is built and
installed in a way that it stays open (or opens up) if it is defective,
which means the oil is going "the long way" through the radiator.
Another detail he mentioned: If you buy a new 912S, ALWAYS buy the heavy
duty starter, the price difference is small compared to the hassle you
will probably avoid.

Hi Nigel
The thing with a lazy thermostat is you know it is not working properly
well before it becomes a real problem.
The other down side for us old chaps with bad memory is remembering to
adjust the flap that controls the oil temperature! It is something else
to remember, I know eventually it would be left on when it should be off
or vis versa. It is a bit like carb heat controls that we all know have
to be operated but aeroplanes loose engine power regularly because of
carb icing. The thermostat just gets on with it and does not require me
to do anything. I totally agree with you about mod approval, but I
still know which I would prefer.
There are aeroplanes (not Europas as far as I know) out there with both
oil and water thermostats which are, I believe, approved mods.
Regards
Pete

Very odd... I have a mod 'approved subject to flight test' for fitting an
AoA that taps into the pitot-static system.
I might have a chat with Francis on that one :-)

I'm assuming you mean 93MON as I think that's the highest-rated fuel
normally available at the pumps in the US. Can you confirm?
Over here in the UK where we measure in RON, we have 95-octane Ornery
Unleaded and 97ish-octane Super Unleaded (BP Ultimate is 97, Total Super is
98, Esso Supreme is 97 to 98, Shell Optimax is 97.6, Sainsbugs own-brand is
97, etc.).
I though the line was that we should us ordinary unleaded, as super is more
prone to vapour lock. Can someone in the know comment?
It would be interesting to see how Optimax fares on that as it is actually
to the British Standard for ordinary, but of a higher octane rating, while
the other are to the BS for super - I forget the exact BS numbers (5050?
9090?).
(In case anyone is wondering why I'm so familiar with the fuel standards of
the different suppliers in the UK, it's because my car is designed to run on
a diet of super and is extremely sensitive to the fuel I feed it! The right
fuel = more grins! :-))

Jeremy
