Oil Cooler, Part 3

Well, I think it came out okay. It's hard to tell unless you look really close, but I had a problem getting the part off the mold. As a result, the bottom edge of the NACA duct isn't exactly perpendicular to the inside edge (which means it's not perfectly parallel with the top edge). In theory, that might reduce the effectiveness of the scoop, but since the cowl curves inward as it gets near the front, the scoop isn't exactly parallel with the airflow, either. In fact, it might end up working more like an extended inlet, rather than a submerged inlet.

Total Time: 10.5 hrs.
