In this video I take a deeper look at vibrations and damping as they relate to FPV quads. We see how vibrational energy is generated, stored in resonant modes, and eventually dissipated as heat. Finally we look at several different methods of increasing damping and therefore reducing vibrational energy in our FPV drones.
