Scott,

I’m new to the LML site but I have built several = aircraft over the years. One thing that scares me on the Lancair is = flutter. I recently found a IV elevator trim that could easily be moved up and = down as much as 1” at the trailing edge. It turned out to the hinge = that the tab was attached to was bending. The owner had not had a = problem with flutter but the hinge was completely worn out due to vibration in only a = couple hundred hours. Lowering the attach point on the horn reduces the = leverage and increases the movement of the tab. This will make it too = sensitive and lessen the arm needed to prevent flutter. I don’t = recommend it.
