Hi,
I have a Dynamic WT9 plane with a Rotax 912ULS 100 hp with 400 hrs, I flew the plane and governor stop

after landing check it and carbon tube rod was broken and change it but propeller make vibration.

 i check engine with another fixed pitch propeller and  engine don't problem .

my propeller is DUC FLASH BLACK  3 blade constant speed.

What was the solution?
