11. IGYRO
The iGyro menu provides access to a whole range of Expert settings which enable
you to ne-tune the iGyro to meet your specic requirements.
The iGyro menu requires an iGyro SAT connected to the FastTrack input of the Po-
werBox Mercury SR2 as sensor unit. An optional GPS III or PBS-TAV also connec-

ight with the base values then forms a good starting point for further ne-tuning.
• Gyro Axys

available for each of aileron / elevator and rudder.
• Range
Two ranges are available, each of which can be adjusted separately for each axis:
range A and range B. Range A applies to values of the gain control (or gain switch,
once set up) between 0% and +100%, while range B runs from 0% to -100%. At 0%
the iGyro is completely disabled.
This enables you to set up two ranges: one range with Attitude Assist and a se-
cond without Attitude Assist. You can select either range in ight by means of a
switch.
• Attitude Assist

de Assist can also be used on the elevator without any problem, as it is only active
at the stick’s centre point, and there is no risk of causing a stall. As soon as the
