if your blade wobbles between lead and lag to find true in several rotor revolutions.. its center of gravity is not balanced correctly.. though if the CG was balanced properly, it would assume its proper attitude instantly.. The Blade has to be in a lead or lag attitude to strike the tail..
I understand it's important to balance the blades, but when a heli hits the ground I don't see how balancing could help. A friend crashed his JR Voyager E (.30 size electric) straight down after hitting the battery cutoff yesterday. He suffered a dent in his tail boom from the blades even though he has a perfectly balanced setup and is using MS carbon blades. Maybe if the o-ring dampers were worn, that could increase the chance of a boom strike. I don't understand how balanced baldes would effect boom strikes in a crash. Please explain. Thanks.
