No need to worry about all that. It isn't worth the effort or necessary. Just balance your prop the VERY best you can, make sure all the wire and any other loose ends are tight and not flopping around, and fly. It will always make a drumming sound. It is caused by the thick wing and tight monocote. Sorta like a.... a.... Drum. Just don't worry about the noise. When you get the prop balance I think much of the noise will go away. I don't even notice mine anymore. Maybe I'm just getting used to it. Also, make sure you don't fly to fast. This makes the noise worse and can be destructive. This is a slow flying 3D airplane. Keep it slow.
Thanks,
