FailSafe (loss of clean signal and low receiver battery) submenu (F/S): Sets responses in case of loss of signal or low Rx
battery
Examples:
•
Set the throttle channel so that the engine idles when there is interference (ACRO). This may give enough time to fly away
from and recover from the radio interference and minimize damage if crashed.
•
For helicopters, NOR is typically the safest choice.
Updating F/S Settings: If you specify a F/S setting, the FailSafe data is automatically transmitted always.
When you choose the F/S mode, check that your settings are as desired by turning off the transmitter power switch and
verifying that the servos move to the settings that you chose.
GOAL of EXAMPLE:
Change the receiver FailSafe command
for channel 3 to a preset position.
NOTE: This is one of several functions
for which the radio requires
confirmation to make a change.
Where next?
Battery FailSafe (F/S ): A second battery low warning feature (built into the 2.4GHz receiver).
When the airborne battery voltage drops below approximately 3.8V, the receiver's battery F/S function moves the throttle to a
predetermined position. When the Battery F/S function is activated, your engine will move to idle (if you haven't set
a position) or a preset position. You should immediately land. You may temporarily reset the Battery F/S function by
moving the T S

reactivates.
Adjustability:
•
NOR F/S setting for throttle results in Battery F/S going to the servo position reached by moving T
bottom with T L
RIM EVER
•
POS F/S setting for throttle results in Battery F/S also going to the same throttle servo position as the regular F/S .
If using a 6V (5-cell) receiver battery, it is very likely that your battery will be rapidly running out of charge before
battery FailSafe takes over. It is not a good idea to count on battery Fail Safe to protect your model at any time, but
especially when using a 5-cell battery.
.
FailSafe (F/S ): instructs a receiver what to do in the event radio interference is received.
Adjustability:
•
Only channel 3(throttle) may be set.
•
The NOR (normal) setting holds the servo in its last commanded position.
•
The F/S (FailSafe) function moves servo to a predetermined position.
•
NOTE: the setting of F/S also applies to the Battery F/S(see below).
STEPS:
Open the BASIC menu, then open
F/S function.
Set and confirm fail safe command.
Close.
Wait two minutes and confirm F/S settings as described above.
