A4 Receiver Advanced Protection Function
You are asked to enable this function by connecting to the Assistant Software, please set it at the section of
Basic->R/C-> Receiver Advanced Protection.
If you choose enable it, the FailSafe will be triggered if the following situations occur during flight.
According to the difference of the aircraft height, there are two situations.
a)
Lower than 100m, the A/E/R channel is not at the mid point.
b)
Higher than 100m, the A/E/R channel is not at the mid point or the throttle stick is above the mid point.
In the GPS Mode or ATTI. Mode, if the requirement a) or b) is satisfied, and the output data of four channels
A/E/R/T have not changed for 20 seconds, then the aircraft will hover automatically. After that, if the output data
of four channels A/E/R/T still do not any changes and last for 10 seconds, the autopilot system will think that the
data from receiver is abnormal, and then enter the FailSafe Mode.
