That’s correct, Joe. = And that’s the problem; I get none of this airflow through the oil = cooler. I was hoping for more natural convection through the oil cooler, but there = is very little. It may be a little better with the cooler in the wing enclosure – natural convection needs a “chimney”. = Maybe I’ll need to somehow duct some of the cooler exit into the = cowling.
