[current stick position] which shown as number -1000
to +1000 in real time, click button, save them into

been correctly set or your throttle position is holding on throttle-cut (STOP) position. Please check your throttle-cut switch and throttle
working range setting in Assistant Software page –Engine. See page16 for details.

mind that, once the helicopter is in the available transmitter signal range, you re-gain the control right for WKH Lite system
whichever control mode you are in!
