EXAMPLE OF GYRO ADJUSTMENT
WHEN MOUNTED IN A MODEL
HELICOPTER.
• Set the gyro output trimmer to graduation 7 using
a small flat blade screwdriver.
• Adjust the output trimmer so that tail (rudder)
hunting does not occur when hovering with heli-
copter fuselage facing the wind and when turning
and flying straight ahead.
• If hunting does occur then lower the sensitivity by
reducing the gyro output trimmer. When you
sense that gyro sensitivity is low then increase
gyro output trimmer to desired sensitivity.
POWER SUPPLY
•The G154/G134 Rate Gyro uses the same power
supply as the receiver and servos.
•When the receiver and gyro use a common power
supply, rudder/servo power consumption and the
power consumed by the gyro, increases the total
power consumption. This decreases the number of
permissible flights. The use of a high capacity
(4.8/1,000mA) Nicad battery is recommended
(The Futaba NR-4LB (4.8V/1,000mA) Nicad bat-
tery pack can be purchased separately.)
Low when hunting occurs
Gyro
output increases
Control amp.
•Do not expose the rate gyro to shock and vibra-
tion
•Do not disassemble or modify the rate gyro
When the imide of the gyro must be inspected, remove
the three screws on the side of the case and remove the
cover. Do not loosen the screws on the bottom of the
case.
• When the gyro output trimmer is set to zero, the
gyro sensitivity becomes zero.
• When the gyro power switch is set to OFF, only
the gyro motor is turned off. At this time, since
the control amp operates and the connected
servos may be operated by fuselage vibration.
When flying, always set the gyro power switch to
ON.
• When a gyro output switching function is requir-
ed, such as in competition, etc., purchase the
G153/G133 or G153BB/G133BB from your
local Futaba dealer.
When requesting repair after long use, accident, or
if any other trouble has occurred, describe the
problem in as much detail as possible. This will
allow us to isolate the trouble point quickly and
reduce the repair time.
