1. Foreword:
The robbe Piezo-Gyro G 300 is a gyro system based on a piezo sensor, and is sui-
table for fixed-wing model aircraft and helicopters.
If an external influence such as a gust of wind, or a rapid change in rotational
speed or collective pitch pushes the model out of its intended position, then the
piezo-sensor picks up and measures the change, converts it into a compensatory
signal and passes it to the tail rotor servo
which then carries out the necessary cor-
rective action.
Note:
If you wish to achieve maximum perfor-
mance the Piezo-Gyro G 300 should
always be operated in conjunction with a
very fast tail rotor servo. Of course, servos
of normal transit speed can still be used,
but the stabilisation effect will not be quite
as perfect as with a super-fast servo.
Recommended servos:
4.8 Volt power supply (4 NC)
S 9203 servo Order No. F 1264
6 Volt power supply (5 NC)
S 9402 servo Order No. F 1253
2. If you are in a real hurry, here are
brief instructions for getting the gyro
working:
-
Connect the system as shown in Sketch 1
-
Switch on the transmitter, switch on the receiver
-
Do not touch the model or Piezo-Gyro G 300 for
about 10 seconds while the Piezo-Gyro G 300 car-
ries out its zero calibration procedure.
-
When ready -> tail rotor servo runs to starting posi-
tion and the red „Ready“ LED on the Piezo-Gyro G
300 lights up.
-
Move channel 5 slider to centre (50% gyro Gain con-
trol).
-
Check the direction of operation of the gyro and ope-
rate the reverse switch „REV“ if necessary. Switch
off, then on again and check the result.
