the flutter movement is not coming from the wooden pushrod, it is coming from the whole setup itself. Let me try and explain in more detail. THe control rod consists of a long wooden dowel. towards the tail of the plane, 2 metal pushrods are taped to the dowel and form a Y. Each end of the "Y" exits from a different side of the fuse- going to each of the separate elevators. THe problem, is that there is nothing anchoring this whole setup so it moves around inside the fuse. They should have used pushrods anchored to the fuse frames. THe problem I have is that there is no room for my hand to fit in the fuse to anchor anything to it. I know this sounds confusing, but if someone else out there owned a macchi from VQ, they would immediately know what i am talking about.
