Step 2 Fail‐Safe Setup (F/S)
There are 2 ways of setting up F/S: default mode and optional mode
1) Default F/S mode
Check with your Radio manual on how to set the Receiver failsafe. Ensure that when you turn OFF your radio,
your failsafe settings are as follows:

Default F/S only has Return and Land mode which means the YS‐S4 will command the aircraft to Return and Land
automatically if the communication between the TX and the autopilot is disconnected.
2) Optional F/S Setup
IMPORTANT
1) This only applies to FUTABA transmitters.
2) "Optional F/S" is not recommended for beginners because the setting procedure is very complicated.
