Rino,
Do you have coolent and oil thermostats in your
system?
If you did you should not see such low temps.

both oil and water temp were
about 125 F on final to landing which I feel is too cold for
a landing overshoot. I normally take off when the oil
temp is 140 F or more. I would like to see above 160
temp all the time for oil and water.

Re: Cold Oil ... was Spark Plugs
I’m
curious about the comments with regards to the cold
engine … are you more concerned about oil or water
temp?
Lynn
has posted several times that oil temperatures ABOVE 160F rob
power from the rotary, so that should mean oil temps below
160F are a good thing.
How
low is too low?
On
my last flight the oil temp was about 135F in cruise … with
synthetic or multi-viscosity oil (15W50 for example), low oil
temps should not be problem.

How
long do the sparkplugs should last on the Renesis
engine.
My
engine is starting to run rough and I suspect the
plugs.
I
have to say that it is also running too cold, it goes down
to about 160 F (oil and water) when coming in for a
landing which is usually 3500 rpm. I have the NGK
iridium plugs, lead RE7C and trail RE9B.
I
am trying to warm up by blocking the radiators at the
moment. OAT between 30 and 40 F.
I
will have to build shutters to control the engine
temp.
Last
month the engine was too hot, now it is too cold. I did
modify the air ducts and change the oil rad for the original
RX7 rad.
