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.

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.
