I quickly made up a Naca Vane and bonded it into the naca affectivley splitting the angle of attack between the two extremes in hopes of getting more laminar flow air to the cooler as Hertzler believes this may be a reason for the high oil temps. Not to mention the big ol voltage regulator fins sticking out into the air stream. I'd hate to have to move the regulator to a different location again but if I have to I will. For now I'm even willing to add a second oil cooler before doing that :) This will shed light on what's going on inside the expansion chamber for sure. Hopefully getting to test fly her tomorrow.
