Nick, I have a question for you,
When we converted out S-76A's to A++'s we removed one set of bifilars. We have been told that the C30 engines have a rotor induced resonance in the PC air system that the second set of bifilars helped lessen and the 1S1 engines don't have this problem. Is this true?
