FAIL SAFE Sets the servos operating position when transmitter signals can no
longer be received or when the receiver battery voltage drops.
(The display screen is an example. The
screen depends on the model type.)
The Failsafe function may be used to set up
positions that the servos move to in the case of
radio interference.
You may set either of two positions for each
channel: Hold, where the servo maintains its last
commanded position, or Failsafe, where each
servo moves to a predetermined position. You may
choose either mode for each channel. (FASST 7CH
mode: CH3 only)
The T8FGS system also provides you with an
advanced battery monitoring function that warns
you when the receiver battery has only a little
power remaining. In this case, each servo is moved
to the defined failsafe position. (FASST 7CH
mode: CH3 only) The battery failsafe may be
released by operating a predefined control on the
transmitter (default is throttle), do not continue
Fail safe setting procedure
1. Move the cursor to the "F/S" item of the
channel you want to set and touch the RTN
button to switch to the data input mode.
2. Select the F/S mode by scrolling the touch
sensor. A confirmation message appears.
*The display blinks.
3. Touch the RTN button. (Touch the S1 button
to stop setting.)
*The channel switches to the F/S mode.
4. Move the cursor to the "POS" item.
Hold the corresponding stick, knob, slider,
etc. in the position you want the servo
to move to when the fail safe function is
activated and Touch the RTN button for one
second.
*The set position is displayed in percentage.
*If you want to return that channel to the hold mode, move
the cursor to the "F/S" item and touch the RTN button
to switch to the data input mode. Select the F/S mode by
scrolling the touch sensor. A confirmation message appears
and then change the mode by touching the RTN button.
to fly, land as soon as possible. Remember, if the
predefined control suddenly moves to a position
you did not command, land at once and check your
receiver battery.
Defines servo position when signals are lost and
when receiver battery voltage becomes low.

WARNING
 For safety, always set the fail safe functions.
●Especially set the throttle channel fail safe function so that
the servo moves to the maximum slow side for airplanes and
to the slow side from the hovering position for helicopters.
Crashing of the model at full high when normal radio waves
cannot be received due to interference, etc., is very dangerous.
●If the battery fail safe is reset by throttle stick, it may be mistaken
for an engine malfunction and will be reset at throttle slow and the
model will continue to fly. If you have any doubts, immediately
land.
Battery fail safe setting procedure
Battery fail safe can be set for each channel
by the same method as the fail safe setting
procedure. Select and set the "B.F/S" item.
[ON]: Battery fail safe function ON
[OFF]: Battery fail safe function OFF
Battery fail safe release switch setting
This function temporarily releases the battery
fail safe function for the fuselage to recover
after the battery fail safe function was
activated by a drop in the receiver battery
voltage. This setting selects the switch which
releases the battery fail safe function.
1. Move the cursor to the [RELEASE B.F/S] item in
the setup screen (last page).
2. Touch the RTN button.
*The switch selection screen is called.
*For a detailed description of the switch selection and ON/
OFF direction setting method, see [Switch Setting Method]
at the back of this manual.
