FailSafe (loss of clean signal and low receiver battery) submenu ( F/S ): sets responses in case of loss of signal or low Rx
battery.
FailSafe ( F/S ): instructs a 2.4G receiver what to do in the event radio interference is received.

the THROTTLE STICK to idle. You will have about 30 seconds of throttle control before the battery function reactivates.
Adjustability:
‡ NOR F/S setting for throttle results in Battery F/S going to the servo position reached by moving THROTTLE STICK to
the bottom with TRIM LEVER FHQWHUHG
‡ F/S position setting for throttle results in Battery F/S also going to the same throttle servo position as the regular F/S .
