    …_CUTOFF.
    
    A low gyro cutoff is needed for most medium/large size drones as the structural natural and blade-pass frequencies are low.
    A higher value is still desirable for small platforms surch as racers
    or well isolated autopilots and should be tuned by the user.
    Specific values for config files are untouched.
    The cutoff filter for the D term is disabled here as the required
    cutoff frequency for the default D term of the rate controller is higher
    than the gyro cutoff. In that case, enabling the D term cutoff would
    just add some undesired phase lag to the derivative.
