Balancing Act

摘要

With modern manufacturing processes the vast majority of propellers for model engines are supplied balanced and ready to run. However, a prop that is out of balance, even by a small amount can generate extraordinary levels of vibration. The frequency of these vibrations can in some circumstances literally shake an airframe to bits. Even low levels of vibration can set up harmonics through the whole airframe, which can have a detrimental effect on delicate electronics, like your receiver and servos! In extreme cases vibrations can cause metal fatigue and wreck your engine!
