Hi All....
A big Thank You to all who answered my questions in
regards to hanger designs and cold weather kits for the 'Coupe.
Helmet sent along a bunch of links that included a
small simple Tee hanger made for an ultralight,made of tube steel. Looks like I
may have a winter project in that one.
As for the Cold Weather Kit. I'm going to try to
fabricate an aluminum plate to cover the cooling air intake in the cowl. I
will install this from inside the cowl and secure it using 3 "Click Brand" stud
kits. ( they are studs embedded in a base plate and are adhered to a surface
using a very quick set acrylic adhesive). The only design element left to figure
out is how to cover up the rectangular hole I will put in the plate for engine
pre heat air (an auto motive car interior heater). I will probably go with
Camloks and a cover plate.
This leads me on to another question.
We run a C-85 12 F TT about 700 hrs, TTSO 150
hrs,Chromed cylinders. Used mineral oil first 25-30 hours then Shell w100 and
Shell w-80. STC with MOGAS or 100ll with TCP additive.
Currently we house the coupe in a rented
unheated hanger.
I purchased a spin on oil filter earlier this year
from John at Skyport (thanks a bunch for all of your help to 'Coupers everywhere
John !) and it works great. Oil temps run a consistent 7-10 degrees lower than
the calculated 100 degrees over OAT that seems to be the norm with Coupes.During
the summer time it is not difficult to run the oil (Shell w-100) temp up to
180-190 degrees.
I have also read though that to get any
condensation (water) out of your oil that the engine oil temp should be at 170
degree or higher to burn it off. This time of the year where I live, Cold Lake,
Alberta, my oil temps run about140-160 degrees (oat about 30 -50) and down
to about 120 degrees at the height of winter (oat about 5 degrees). I am also
using Shell w-80 oil in the winter. I currently preheat both the oil tank and
the case, and can usually get the oil temp gauge to read about 40-60 degrees
prior to cranking the engine over. I then let the engine warm up to at least 90
degrees prior to flight.
Question is, should I be trying to run my oil temp
up to atleast 170 degrees in the fall-winter-spring months to burn off
any condensation which might occur in the oil? How important is
this?
Should I be greatly concerned if I don't run it to
170 degrees. Most of our winter hops are for about an hour or so, should
they be longer to run the temp higher?
Any other advice on Cold Weather Operations.
Cheers
