Till 1 year ago it has been a great concern, especially for small drone. Now thanks to andyp1per, new Ardupilot dev, we have amazing results with dynamic filtering gyroscope noise, we could even track the mechanical noise peak based on actual RPM or live FFT. Harmonic Notch Filter in Ardupilot https://ardupilot.org/copter/docs/common-imu-notch-filtering.htmlhttps://ardupilot.org/copter/docs/common-imu-notch-filtering.html https://ardupilot.org/copter/docs/common-imu-notch-filtering... new and ongoing development https://github.com/ArduPilot/ardupilot/pull/13121 https://github.com/ArduPilot/ardupilot/pull/13121 https://github.com/ArduPilot/ardupilot/pull/14010 https://github.com/ArduPilot/ardupilot/pull/14010

This was about mechanical strain from vibration.

  You have to consider under the selected IMU, in the center, there is the most of the mass, made by the single 18650 Li-Ion battery. This solution is working, ArduBee is already flying good with the low pass filter in the gyro sets at 110Hz, if vibration would be an issue I guess it cannot fly https://discuss.ardupilot.org/t/ardubee-a-ready-to-fly-micro-drone-for-education-and-swarming/54362/11 https://discuss.ardupilot.org/t/ardubee-a-ready-to-fly-micro...

    Again, this issue is not the IMU, it's the whole thing breaking mechanically.
