Neil,
        I have tried looking for this drone sound while flying my 

RV-6A, but if

it is there, it is not very noticeable.  I believe I have detected a
sound similar to what you describe, if I listen hard, but at least so
far it is not normally noticeable.  I am using a Performance prop 

68x72,

Ross PSRU and synthetic oil.  However, it is rather noisy with no side
uphostery and I just may be missing the sound.
