Oil Cooler
in General Tech Discussion

Gents;
Some time ago I wrote saying that my oil temperature on my 912 ULS would rise to 240+ deg during an exerted climb in Hawaii, and that I did not like this.
Some of your replied that this was not unusual, especially during the summer ( I live in summer for 12 months in Hawaii :O)
I asked whether or not some of you had purchased and installed the "new" oil cooler ( specifically on a CTLS 2007, like mine ). And, if so, whether or not it produced a significant oil temperature drop as predicted.
Anyway, I purchased the latest one; removed the oil cooler & radiator ( they were welded together--ugh ); asked California Power Systems & Flight Design USA about the installation ( they were not very helpful... ); had the old oil cooler detached from the radiator, and professionally welded the new one back on the old radiator. I have by now flown it several times.
So, what happened?
My oil temperature dropped about 15 deg F, and today ( again ) would not even move into the yellow on a 650+ fpm climb to 4,000 feet. On cruise at 4,000 ft, at 5200 rpm, the temp averaged about 210F.
Perfect...So; those of you with temperature concerns might consider this !
