Because the MEMS type sensors used on this board use vibrating structure technology to sense movement they generally require a low vibration surface to mount to. Any high frequency vibrations can throw off the sensors and disable the control board. This is why I must devise a vibration absorbing system for the board which will isolate the sensors from any disruptive vibration caused by the brushless motors.
For this I am going to use a set of silicone tubing pieces to make a set of shock absorbers that will hopefully null out any vibration from the motors of the copter. I am going to use some plastic tubing “studs” to attach the board to the tubing pieces as seen below.
