The picture shows the orientation of the RO-WING 300 in a fixed-wing model aircraft. It is
absolutely essential that you keep to this position. The rotational axis of the gyro must be
installed parallel to the lateral axis (wingspan) of the model. We recommend that you install
the gyro in the fuselage close to the CG, because that places it close to the axis which is
to be monitored and stabilised.
For this application the elevator servo (channel 2 in robbe/Futaba systems) must be looped
through the gyro via function 1. The second input and output are left unused. The "AUX"
cable can be connected to any free channel.
Stabilising a model aircraft around the vertical axis
The method of installing the gyro to stabilise the
yaw axis is shown in the sketch.

Installing the RO-WING 300 in a fixed-wing model aircraft with the aim of stabilising the yaw
axis provides several specific advantages in addition to the standard one of automatically
compensating for external influences and turbulence. The gyro provides a crucial improve-
ment in the take-off behaviour of model aircraft. In a side-wind any fixed-wing model tends
to shear off to one side, but the gyro suppresses this unwanted movement effectively. With
a well set-up gyro your model will take off as if on rails.

Using the fixed-wing gyro for the first time

Install the RO-WING 300 in the model as described for your particular application, and
connect it as shown in these instructions. Switch on the transmitter and then the receiving
system. When you switch on the power supply, the gyro carries out a self-calibration pro-
cess which lasts about 10 seconds. If the gyro is to complete this process accurately and
without errors, it is absolutely essential that you do not move the gyro during this calibrati-
on period. Leave the model standing motionless on the ground, and do not touch it at all.
The "Ready" LED lights up to signal the end of the zero calibration process. However, if the
model is moved, or if the monitor LED flashes, the calibration process fails. You must then
