Cooler is Better!

Here is a note from our chief pilot/mechanic, Rob Peterson, after our recent maintenance and upgrades:

Hello Brock and Steve,

I took a couple pictures during the flights recently and wanted to send them to you for an initial report.  The short-and-long of it is that I’m really happy with the investment in the remote oil cooler. Temperature are indeed significantly lower even with new cylinders!  I had to wait for landing traffic leaving Libreville and the temperatures where still fine on takeoff.  I’m not getting about 360 at any phase right now.

The first picture is flying from Yaounde to Libreville with 1.5 – 2 hours on the cylinders.

Running rich-of-peak at 15.5 GPH.  The hottest cylinder hovered around 360 with the cowl flaps wide open.

.The second picture was this weekend on the flight to Douala. 

9000' running at 11.5 GPH LOP with the cowl flaps almost closed. Max temp 355.

Here is a picture is of the remote cooler inlet duct.  Dennis (SIL partner in Cameroon) did a great job painting!
