Anti-vib construction

Any material has some natural resonant frequency, this is a common sense in Scientific field. Combustion motor has has vigorous energy to shake any connected material with, servos, battery, switch and connecting rods especially with rudder and elevator. I knew the fact that the rods are shaken with incredibly wide amplitude waves, the phenomenon was observed that the repetitive shaking could easily destroy the rod structure, it was experimented when the motor was operated without main wind in position. The model airplane falls down immediately after loosing control by a 10mm diameter balsa rod breakage. So, make I it a rule to form the Anti-vibration construction as shown in photos. Not only 60 motor plane but also a smaller motor plane needs the same, because even a small motor like OS 25LA has enough destructive energy to destroy wooden push-pull rod mechanical construction, if any measure should not be prepared.
I found out the exactly the same way of the Anti-vibration construction in "Nova Lily" for the FUTABA factory demonstration flight by Mr. Naruke 40 years ago.
