title_body: Why is an MPU6000 more well suited for drones than an ICM IMU? I have seen people say that the MPU6000 is the superior gyro chip, even though the ICM chip has a faster refresh rate and is technically superior in any other use.
  
  Why is it better to have a lower refresh rate on a drone’s gyro?
upvoted_answer: It's not superior, it's just good enough, cheap enough and may be more noise resistant than ICM20602. 
  
  There's a bunch of flight controllers with dual IMUs onboard. For example, Lumenier Lux F7 has MPU6000 and ICM20602, you can choose which one to use. SP Racing F7 and H7 series use two ICM20602s fused together. 
  
  Also, there's BrainFPV Radix which uses BMI160 from Bosch Sensortec. It should, in theory, provide a more clean and noise resistant signal without the need for complicated software filtering. 
  
  Refresh rate is another thing in itself. Things start to get worse with higher refresh rates: you get all sorts of noises internal and external to the IMU, which can negatively affect motor speed regulation, which in turn might make motors run hot or even fry. Also, higher refresh rates require more processing power to filter the noise. Running IMU at 8+ kHz with RPM filtering gobbles up CPU pretty quick to the point that the quad even refuses to arm.
