What is Go-Home Switch
Choose a 2-position switch on your transmitter as Go-Home switch. You should toggle the switch from the "Standby" to the "Start" to trigger Failsafe when flying. If already in a Failsafe condition, then the switch will not work.
Go-Home Switch Setting
Connect the correct channel of RX to X3 port of MC. You should assign both positions to "Standby" & "Start", and then tick the CheckBox of Go-Home Switch. Move the switch of channel X3 to Start and then Standby to turn the corresponding area blue respectively. Use the end-point fine tuning on your transmitter to set X3 channel to 30% ~ 100% if software does not give correct response.
Important
If the Go-Home Switch cannot be chosen in the software, may be the X3 channel has been set for remote gain tuning, please cancel it.
