Much better! I would even consider another 1/4" on either side of the exhaust pipes (outboard sides). It would even make it easier to take the clamps off the exhaust tubes, and get them away from the ign lead.
Thank you Bipenut and AKNick. Next time I have the cowl off I will open it up a bit more on the sides and turn the clamps as well. I went ahead a put this one back together last night so I could get it off the workbench. I want to finish up the RedwingRC Yak so I can fly it this weekend if the rains hold off. I think we are wetter than the Pacific NW right now!
