Hey WLM dont have a problem in hover but when at near max all up weight with a heavy person in front seat but still within c of g limits and in a decending turn we tend to get a bad mast ossilation (moves back and forward) bloody scary when not aware of it just have to roll out of turn straight and level and it stops.
Robinson apparently aware of it but dont want to know about it we have 2 raven 44's had them from new and they both do it.
would be interested to know if anyone else has had it there are other cases in NZ that I know of.
