And just the opposite they put a weight on the 407 tail skid to dampen vibrations. I always found it interesting that one could purposely move around vibrations within the airframe especially those with airframe mounted tuning weights like in the 350/355 or 135. A 4-per in one area and life is good, but move that same vib into the tailboom and rivets start to work or skin cracks.
