When balancing a radially folding propeller, such as the MagCAD 60x23, what are some techniques to employ?
A static balance is challenging because the orientation of the blades is not fixed.
Dynamic balancing might seem more natural, however vibration might also come from the way the blades pivot about their hinges as they swing through the propeller arc, similarly to a helicopter's lead-lag hinges.
And does it materially affect things if the blades are mounted horizontally or vertically? When they are mounted vertically, gravity will tend to advance the falling blade and retard the rising blade.
