In the years that it was available, it has never shown that it has any advantage over 8 kHz gyro sampling mode, due to its susceptibility to vibrations, and its high noise level which require aggressive filtering, causing delays in the control loop. For this reason, <strong>support for 32 kHz gyro sampling mode has been dropped</strong> in Betaflight 4.0."
