Reverse; Fail Safe (F/S) - FUTABA 9VAP Instruction Manual

ADJUSTMENTS AND FLIGHT TECHNIQUES

REVERSE

Servo Reversing
This function is used to change the direction of servo operation in relation to control stick
or lever movement.
Setting Method
1) Select the EDIT screen, the select the RE-
VERSE screen by pressing the REV program
key.
2) Select the desired channel with the <- and
-> cursor keys.
3) Select NORMAL or REVERSE operation by
FAIL SAFE
Fail Safe
Fail Safe and Hold Functions
The HOLD (Hold) and F/S (Failsafe) functions
are designed to allow the aircraft to "fly
through" a momentary loss of signal or very
strong interference, rather than experiencing the
familiar "glitch" as the servos react violently to
the unwanted signal. These functions cannot be
expected to prevent a crash however, if the
normal signal interruption is of sufficient dura-
tion.
The HOLD function stops the servo at the posi-
tion held just before the normal signal is lost.
When a normal signal is again received, the Hold
function is released.
The FAILSAFE function will move a servo to
a pre-set position when the normal signal is
interrupted for 1 second or longer (The system
will remain in HOLD for the first 1 second of
signal loss). When a normal signal resumes, FAIL-
SAFE is released.
pressing the NOR or REV program key.
In the display example, RUD (Rudder) is set
to REVERSE.
4) Return to the EDIT screen by pressing the
END program key.
BFS (Battery Fail Safe) Function
The BFS function moves the throttle (CH3)
servo to the pre-set Fail Safe position when the
airborne power supply is nearly exhausted. If no
Fail Safe position has been set, the throttle servo
will move to medium slow (neutral).
BFS can be released by lowering the throttle
stick past the release point (adjustable), or with
the CH9 switch. Throttle control is then regained
for about 30 seconds. At the end of 30 seconds,
BFS will re-engage and the throttle will again
move to the Fail Safe position. Whenever BFS
engages, land the aircraft as quickly as possible
and recharge or replace the Nicd battery pack.
