64mm shroud vibrating in a flat foamie
I have a TechOne SU-27 flat foamie with a 64mm edf.
The edf housing is only attached to the airframe at two points.
At a specific rpm the edf housing resonates badly and contacts the impeller.
I'm tempted to cut out a couple light ply ring segments to glue to housing.
Am I on the right path?
Is this a common issue?
