Finished the sound proofing today. There a number of pieces I cut to fit but I will not install them until later as some riveting and grommets are yet to be done. I will now work on the NACA ducts. My aircraft has rear NACA ducts which the later aircraft do not have, because they do not work very well. I think I am going to drill a couple of extra holes to ensure the are no air noises from the rear ducts
