A high pitch metalic resonace noise developed at speeds above 130kts. I think it is the step on my RV9A. Does anybody encountered this? It is very annoying. When the plane was test flown for the first (I was on the ground), I heard this metalic ringing from the ground when the plane was high speed gliding (engine was idling). Any input how to eliminate the noise?
