ROBBE RO-WING 300 Notice D'utilisation page 20

switch the receiver power supply off and on again, so that the gyro is initialised anew. The
same applies if you alter any parameters after the self-calibration process has been com-
pleted; for instance, if you reverse the direction of gyro effect using one of the micro-swit-
ches. In that case you also need to repeat the self-calibration, so that the RO-WING 300
can adjust itself to suit the new arrangement.
Adjusting gyro sensitivity (gain)
The gain of the RO-WING 300 can be adjusted from the transmitter by means of an auxili-
ary channel. To use this facility you should connect the cable marked "AUX" to the receiver,
using a vacant channel which is assigned to a slider control on the transmitter. This gives
you the means to adjust the gyro effect while you are flying the model, to suit fluctuating
flight conditions and weather.
The gain of the gyro can be set to any value within the range 0% - 100%. At 0% gain the
stabilising effect of the gyro is switched off completely. If you wish to exploit maximum gyro
sensitivity, it is important to switch off any servo travel reduction on the auxiliary channel,
i.e. you should check that full servo travel is available for the gyro gain channel. When you
move the stick to effect a change in the model's heading, the gain of the gyro is reduced in
proportion to the magnitude of the command.
LINEAR
If the opposite effect occurs, i.e. the gyro's automatic response to an unwanted movement
is very weak and slow, increase gyro gain gradually. In this way you can generally find the
optimum basic setting in a single flight.
Although you have now set the basic gain level, it is always possible to adjust the gyro's
sensitivity to suit different weather conditions and flight situations, i.e. you can optimise the
model's flying characteristics to suit the prevailing conditions.
At take-off and landing you may find it helpful to increase the effect of the gyro under cer-
tain circumstances. Air turbulence is very common close to the ground, and you will soon

Gyro RO-WING-300
The illustration alongside shows a transmitter slider set
up to adjust gyro gain. You can determine the slider posi-
100 %
tions which correspond to 0% and 100% gain by moving
the model and watching the effect of the gyro's respon-
se.
The optimum setting for the gain of the RO-WING 300
varies greatly according to the model in which it is instal-
led. For the first few flights we suggest that you set gyro
gain to 0% before launch. Take the model up to a safe
altitude before carefully advancing gyro gain. If you find
that the gyro over-reacts, i.e. the model becomes very
0 %
twitchy around the axis to be controlled, moving con-
stantly to and fro and never staying in one attitude, redu-
ce gyro gain until the model is flying smoothly.
