4. Connecting the gyro system, using the system for the first time
Note: the manual „gain" adjustor is switched out of circuit if you connect the Aux
channel to the receiver.
4.1 Connecting the Piezo-Gyro G 300 and setting it up with gyro gain control
from the transmitter
Important:
- The Piezo-Gyro G 300 detects and corrects the tiniest of deviations, which
means that it does not require assistance from a collective pitch -> tail rotor
mixer (Revo-Mix). We recommend that you switch this mixer off.
- Conventional gyro systems usually feature electronic gyro suppression
(Gyro-Sens.-Mixer) which allows the model to fly high-speed pirouettes. This
is not required with the Piezo-Gyro G 300, since the sensor signal is always
over-ridden by any stick command. The extent to which it is over-ridden is
determined by the servo travel setting (ATV). For this reason the suppressi-
on mixer (Gyro-Sens.) must always be switched out of circuit when the Piezo-
Gyro G 300 is in use.
- For the same reasons all the other mixer functions which affect the tail rotor
(e.g. swashplate -> tail rotor mixer) should also be switched off.
Connect the Piezo-Gyro G 300 between the tail rotor servo and the receiver as
shown in Sketch 1, and connect the „Aux" connector to a vacant slider channel
(e.g. Channel 5).
- Switch on the transmitter.
- Switch on the receiver.
- Leave the model and the Piezo-Gyro G 300 untouched for about 10
seconds while the Piezo-Gyro G 300 carries out its zero calibration process.
- Process complete -> tail rotor servo runs to starting position, red „Ready"
LED on Piezo-Gyro G 300 lights up.
- If you move the model too soon, or the monitor LED flashes, you must re-
initialise the gyro by switching the receiver power supply off and then on
again.
- Move the channel 5 slider to max. gyro gain control (no tail oscillation).
- Set the tail rotor trim to centre.
