That goes without saying.  For everyone's information, I am using 5/8 
(-10) oil lines.

Yes, they are very close, but the top secondary cooler was meant to be 
used for cabin heat, recirculating cabin air.
Ruben's configuration is logically identical to mine, but our approaches 
are a little different.  With an arrangement of flappers, I can dual 
purpose the oil coolers for ground cooling, just like Ruben did.

I ordered a centrifugal fan today:

I also ordered this fan from Wal-Mart:

But I don't think it will fit in the plane.
