F/S Fail Safe
(Throttle channel <ch 3> only)
The Fail Safe function is recommended to use for safety reasons in the event of radio interference. In this menu, you may
select from one of two options. The “NOR”(normal) setting holds the servo in its last commanded position, while the “F/S”(Fail
Safe) function moves the servo to a predetermined position.
The setting is set to “F/S” as a default.
The use of the failsafe function is recommended from the standpoint of safety. You may wish to set the throttle channel so that
the throttle is moved to idle when there’s interference. This may give enough warning to allow you to fly towards yourself and
recover from the radio interference. If you choose to specify a failsafe setting, the failsafe data are automatically transmitted to
the receiver many times during the flight.
Battery Failsafe
Your system provides a second safety function called Battery Failsafe. When the airborne battery voltage drops below
approximately 3.8V, the battery fail safe function moves the throttle to a predetermined position or fast idle, if you haven’t set it.
If this happens, you should immediately land! If you need to increase throttle for your landing approach, you may temporarily
reset the failsafe function by moving the throttle stick to idle, after which you’ll have about 30 seconds of throttle control before
the battery function reactivates.
To set the Fail Safe Function:
1. Enter the programming mode. Access the
“F/S”
screen with the MODE key.
2. Press DATA Input lever downward when you need to set Fail Safe. The arrow moves to
“F/S” side. This means that the F/S function is activated. Then move the throttle stick to the
position where you want the servo to move when
“F/S”
function works and press DATA
INPUT lever downward for about two seconds. A figure in percentage will be shown with
a beeping sound. Press DATA INPUT lever upward if you want to set
“NOR”
. The arrow
moves to “NOR” side and then the “
NOR”
function is selected.
The F/S value is set to 20% of the full throttle for “F/S” function as a default.
3. Verify if the F/S function has been correctly set. Turn off the transmitter, then check if the
throttle servo moves to the position that you set.
