From Spirit System Manual
Although Spirit unit is automatically changing Collective Pitch in this mode, it is always required that pilot have full control over R/C model. Pilot must always watch the model while holding radio transmitter and to not allow flying anywhere where a damage could occur. All functions that the module provide can be turned off at any time and with no delay so that pilot can steer the model normally. Improper operating conditions can lead to a failure of the system.
