The airspeed factor should be increased if the model displays good gyro respon-
se at low to medium speed, but tends to oscillate at high speeds. Over the years
the default value of 4 has proved ideal for all kinds of model.
• Learning the installed orientation
In this menu the unit learns the installed orientation of the iGyroSAT. In most
cases this has already been established in the Setup Assistant, but if you change
the location or the orientation of the iGyroSAT, you will need to use this menu
point again.
The orientation of the gyro is established by moving the model in the directions
shown on the screen: to ensure that detection is absolutely reliable, move the
tail of the model smoothly up and down several times before holding the tail up
until the elevators return to neutral. The direction of effect is not important at this
stage. The diagram of the little afterburners on the screen lets you know whether
the movement was sufcient!
Repeat the procedure with movement of the rudder: move it left and right repea-
tedly, then hold it in the “right” position.
Note: With larger models this procedure can be awkward to carry out. Ho-
wever, there is a simple trick which makes establishing the installed position
easier: don’t x the iGyroSAT in the model until after the learning process is
complete. During the learning procedure you simply move the iGyroSAT in the
appropriate direction, rather than the model itself!
