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.
Adjustability:
• Each channel may be set independently. (
2.4G-7CH
mode: ch3 only)
• The
NOR
(normal) setting holds the servo in its last commanded position.
• The
F/S
(FailSafe) function moves each servo to a predetermined position.
• NOTE: the setting of the throttle's
F/S
also applies to the Battery
F/S
(see
below).
Examples:
• The
F/S
setting is used in certain competitions to prevent the aircraft from flying away and doing potential damage
elsewhere. Conversely, the

long enough to regain control.
• Competition modelers often maintain the
NOR
function so that brief interference will not affect their model's maneuver.
• Set the throttle channel so that the engine idles when there is interference (

from and recover from the radio interference and minimize damage if crashed.
• For helicopters,
NOR
is typically the safest choice.
• We also recommend setting a gasoline engine's electronic kill switch to the OFF position in the
F/S
function for safety reasons.
Updating
F/S
Settings:
If you specify a
F/S
setting, the FailSafe data is automatically transmitted. 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.

Battery FailSafe
(
F/S
): a second battery low warning feature (separate from the transmitter low voltage warning). When
the airborne battery voltage drops below approximately 3.8V, the 2.4G 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
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
centered;
•
F/S
position 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 FailSafe to protect your model at any time. This is
especially true when using a 5-cell battery.
