RE: Flutter problems and Mechanical linkage Setup Lesson Learned
Exactly Tom,
On all my airplanes (precision, 3D, etc) I setup the controls so that the maximum travel needed (not possible.. just needed) is acheived with my ATV's maxed out using the shortest servo arm, coupled to the longest control horn I can get. This gives the maximum leverage at the surface, and you're absolutely correct in the effect this has upon slop.
One other thing.. I know some people are hesitant to use digital servos on this airplane and others like it. The biggest benefit from digital servos is not the torque, or speed, but the fact that they develop their maximum torque at only 2 degrees off center from neutral, whereas a non-digital doesn't reach maximum torque output until around 18 degrees.
Len's article is a good one and worth reading by everyone.
