FUTABA FP-G133 Instruction Manual

The FP-G153/G153BB/G133/G133BB is a single axis rate
gyro designed to stabilize aircraft. Like full size aircraft,
stabilisation is accomplished by detecting angular accelera-
tion with the rate gyro. Detected motion information is fed
to the control amplifier, which then sends a counteraction
signal to the appropriate control surface.
•The FP-G153/G153BB is for Futaba J, M, and SG
Series (1520 us neutral) digital proportional radio con-
trol sets.
•The FP-G133/FP-G133BB is for Futaba E, F, G, H. and
L Series digital proportional radio control sets.
•Voltage regulated gyro motor supply maintains constant
motor speed and allows consistent gyro performance. The
voltage regulator is effective only when used with an ex-
ternal 6V. (five cell Nicad battery).
•Direction of correcting mix can be switched at the control
amplifier (internal reverse amp switch).
•Centering of the channel being stabilized can be adjusted
by a neutral trimmer built into the control amplifier.
•A very sensitive magnetic motion sensor with excellent
voltage characteristics, linear sensitivity, high speed
response is used. This results in superior neutral character-
istics. Such characteristics make it ideal for use with the
rudder channel of a model helicopter or in the aileron/
elevator channel of a model aircraft.
•Large 2mm diameter gyro motor shaft for long life and
strength.
•The highest quality ball bearing is used as the motor
bearing. (G153BB/G133BB only)
•The gyro can be bypassed without affecting normal oper-
ation by turning the gyro power switch "off".
•Gyro output ("sensitivity") can be switched to one of two
preset outputs at the transmitter (use the retract switch if
possible, or any avail, channels).
