Hartmut!
How many hours flying time on your coupe when this flutter
started & what serial #?
Our 415c now has 1590 hrs since new, no sighn of flutter but we will be
getting a dynamic balance
job done soon as there is a fair amount of engine vibration. We already
put new engine mounts in.
Thanks
Darwin
