Well, I can honestly say that this oil cooler mod has taken a lot longer than I expected, but with 100 degree OAT's, I'm not missing the flying yet. The cool news is that both cowl halves are now in grey primer and ready to fly :) agressive sanding earned me a few spots that broke through the grey but it's no problem. I'm just itching for my engine parts to come back so I can test out this contraption.
