Eric, That is the shot i need of the cowl. I was wanting to use a pitts style muffler but that looks good. I watched a video up in post # 9 and was suprised buy the way he flew the plane. Now my wow factor is thru the roof. We don't have a noise rule but I think it best not to stir the pot if I don't have to. Of the 2 colors of planes which one shows up the best in the air? I am leaning toward the blue one. I am planning to be in Bowling Green sometime in the next few months for a seminar. I would like to come fly and check your field out. Greg Garrison with GandL Hobbies tells me you all have a super field. I stopped in the last time I was thru there and talked with the owner of Dad's Toys.
