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 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).
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: STEPS: INPUTS:
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
HROTTLE
S
TICK
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 T
HROTTLE
S
TICK
to the
bottom with T
RIM
L
EVER
centered;
•
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.

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.
