Hello Raz and thanks for the reply. The heli has tipped over but not really "crashed" but I guess that depends on what you call a crash. Once I got the blades tracking it seemed ok but then the vibration started. WRT balancing the blades, are you refering to total weight or weight distribution for a single blade? I'm really new at this so please forgive the simple questions. I've seen a few posts on blade balance but I'm not sure if there is more than one method for a type of balance.
