Setting up the HeliCommand RIGID
Before using the system in a flybar-less helicopter please note
that it is essential to activate RIGID mode (using the PC).
The attitude-maintenance stabilisation ("head gyro") maintains an angle of
inclination once set, and prevents the model from ballooning up into
wind - to the extent of the helicopter's control system's power to provide the
corrective action. You can observe this function at the swashplate, as it will
remain in the inclined attitude you have set.
Depending on the setting, some care is required before take-off to ensure that
the swashplate is not accidentally set at too great an angle (through slow drift
or accidental movement), and that the RIGID gain is not set too high.
Unlike usual practice with tail gyros, the gain setting does not need to be set
hard up to the limit of oscillation!
The HeliCommand must only be used to control flybar-less helicopters
with the Rigid mode switched on !! Otherwise there is a risk of generating
excessive aileron / elevator rates; this could overload the sensors internally, and
this in turn could have a serious adverse effect on the horizontal mode and the
position mode!
Scale models often have their swashplate travels mechanically reduced to
about half of „conventional" aileron and elevator travels. When employing
the HeliCommand, we recommend to undo the reduction, i.e. increase the
mechanical throw in order to achieve optimum stability.
Rigid stabilisation has to be activated using the PC. Please check

basic installation.
