So the Naca Idea seems to have worked out pretty well. The only issue is that it was just barely contacting the oil sump, so I removed the rivets, moved it back by 1/8" and re-riveted it in place. This should be the final position before flight. I didn't want a hot oil sump to start de-forming my naca vent. The next step will be designing a plenum box around the oil cooler for even better temps! GITRDONE!
