Carson Gyro CG-1 Mode D'emploi page 17

Warning!
GB
If you use an electric model helicopter, disconnect the engine from
the regulator in order to prevent uncontrolled running of the rotors.
If now the tail of the model helicopter is quickly turned to the side,
the servo has to perform a turning. If the servo lever immediately
returns to the central position (neural position) after every manual
turning movement, the gyro operates in "normal mode".
If the servo lever only returns to the central position (neutral
position) when the tail was turned back to the initial position, the
gyro is working in heading lock mode. In this case, change the
function orientation of the sliding controller in the reverse menu
on the sender.
Attention important!
If the servo lever runs in the "heading lock" operating
type until the stop, the sender trimming (subtrim) must be
set so that the servo lever is nearly stable in the central
position or runs only very slowly to the stop.
Tip:
The required settings of gyro CG-1 sensitivity for the initial flight
depends very strongly from the respective model and from the
servo used. The better quality and faster the connected servo is,
the greater the maximum flyable gyro sensitivity. For the first flight
you should set a sensitivity value of approx. 75%.
