I guess i'm just trying to say is fuel foaming really a problem?, or is it another problem that causes it?, i just wonder when everyone says fuel foaming is a problem and you should add foam around your fuel tank, in my case the foam would only mask an unbalanced prop. And isn't flutter usually caused by sloppy linkages and sometimes the size of the gap between the control surfaces?, so is flutter the actual problem or was it the loose linkages that caused it?.
So i guess fuel foaming and flutter is the end result of other problems, and unless you cure the root problem the end result will not go away.
