Hello, I fly a 1979 Nimbus 2 carbon, and since a few years I hear a cracking noise behind me.

Count your blessings. I have a howling banshee in my tail boom.

Flub, what are you flying. I removed the V seals in my Nimbus 3 rudder one year and the banshee took up residence at speeds over 90 kts. Once they were replaced, the banshee was banished.

Cheers,
