Dan,

       Unfortunately I'm unable to help you with any noise testing as my ES
is not flying yet. I have the factory soundproofing kit and will admit it is
a bit heavy! I haven't installed too much of it only under the floor. I am
interested though in your progress and do appreciate any of your post. Good
luck with your project!
