Hello everyone. I have a question, I have a RV-8 with 170 hrs. I completed it about a year and a half ago. Since the beginning we would hear a noise that sounded like the cowling vibrating it seemed to be more pronounced at high attitudes and it would fade when I would yaw to the right or left. I made numerous adjustments to the cowling but the problem still existed. The weird part is sometimes it will completely go away but then return at random. Finally this summer on the way back home from Oshkosh I was in the back seat and my son was flying up front. I closed the rear vent and the sound went away and I would open it and the sound would return I thought aha mystery solved, well sort of. Now I’m wondering why am I hearing this noise through the vent? I was thinking maybe its prop tip nose because it’s closely aligned with the wing vent. Or maybe it’s the hose clamp vibrating on the vent hose in the wing. I was wondering if anyone else has experienced this?
