Default Mid-range rattle ?

Hi Bax, I have an OS 1.60 fx that runs beautifully. Top end, bottom end, and transition all excellent. However, the mid-range rattle brings a lot of stares, and comments at the field. I have been told that the noise that I am hearing is harmless, is this true ?

Running 10% nitro, synthetic/castor blend 19%, 16x10 prop, A5 plug, always on the rich side.

Thanks > Jim
