Detailed instructions for use are in the User's Guide.

[. . . ] The FP-G132/G152 is a single axis rate gyro designed to stabilize aircrafts. Like full size aircrafts, stabilisation is accomplished by detecting angular acceleration with the rate gyro. Detected motion information is fed to the control amplifier, which then sends a counteraction signal to the appropriate control surface. ·A very sensitive magnetic motion sensor with excellent voltage characteristics, linear sensitivity, high speed response is used. [. . . ] (Insert the jumper connector when a shared power supply is used. ) (C) Connector G132 (D) Connector Connect to the servo (rudder servo for helicopter) Black The G152 and G132 are interchangeable by changing the connectors and readjusting the neutral trimmer. (D) Connector G132 RATE GYRO INSTALLATION NOTE: Be sure gyro is mounted as shown; for stabilization of the correct axis. Helicopter - For rudder use Connect connector (A) to the receiver rudder channel and connector (D) to the rudder servo. Aircraft - For aileron use Connect connector (A) to the receiver aileron channel and connector (D) to the aileron servo. Aircraft - For elevator (pitch shaft) use Connect connector (A) to the receiver elevator channel and connector (D) to the elevator servo. ·When the gyro is mounted 180° out of phase, the direction of the correcting mix will be reversed. To correct this situation, switch the internal reverse amp switch to "REV". After mounting the gyro to the fuselage, recheck its direction of operation. INSTALLING THE GYRO BODY ·The best mounting position is at the center of gravity of the aircraft; however, it may also be installed a short distance away from the center of gravity. ·The gyro can be installed with dampers, grommets, screws, or with double-side tape. INSTALLING THE CONTROL BOX Using the control box nameplate as a template, drill four holes and cut an opening for the slide power switch. Mount the control box on the fuselage, away from engine exhaust and where there is minimal vibration. Pan head tapping screw(2) 2x8 Switch box nameplate Flat washer Rubber Bushing Grommet Switch box (top) Switch box (bottom) Flat washer Nut Double-side tape (clean the surfaces, then attach the double-side tape) Use 2. 3 - 2. 6mm diameter nuts ·Wrap the control amplifier in sponge, to prevent vibration problems. OUTPUT ADJUSTMENT ·When using the switchable gyro output sensitivity feature, connect connector (B) to the retract channel if possible. The output sensitivity switching point will then be at the center or neutral area. ·When the transmitter landing gear switch is pulled forward (or down), the output sensitivity can be adjusted from 0 to 100% with trimmer ( 1 ) . *When the transmitter landing gear switch is pushed back (or up), the output sensitivity can be adjusted from 0 to 100% with trimmer (2). In this case, trimmers (1) and (2) do not interfere with each other, and can be adjusted independently. ·When the output is fixed or there is no spare channel (as with 4 channel set), do not connect connector (B). In this case, adjust the output with control box trimmers (1) and (2). (Insulate the terminals with vinyl tape so they cannot be touched. ) EXAMPLE Adjustment when installed in a helicopter: When using the switchable output sensitivity: Set trimmer (1) to about the 70% of maximum output sensitivity position (100% is full clockwise) as a starting point. Hover with the wind and readjust trimmer (1) so that "tail hunting" does not occur. However, do not reduce output sensitivity to a point where the nose will turn upwind when "lifting off". Set trimmer (2) to about the 40% position when a large rudder travel is unnecessary, such as 540° stall turns, etc. Approx. 40% Approx. [. . . ] (The Futaba NR-41 (4. 8V/1000mA) Nicad battery pack can be purchased separately. ) BATT ·Do not expose the rate gyro to shock and vibration ·Do not disassemble or modify the rate gyro When the inside of the gyro must be inspected, remove the three screws at the top of the case and remove the cover. If these screws are loosened, the neutral position may change at sensitivity or polarity switching. 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.
