What happens if the joystick rest position is a little off-center?
Normally, when the joystick is centered on the radio, this corresponds to an off command on motor 1 and motor 2. In reality, the center position on the radio may not be the “ideal” center, causing a small command value to be sent to motor 1 and/or motor 2. To prevent this, the AX2550 can be configured to use one of several possible deadband values. The deadband will cause the controller to acknowledge radio commands only when the joystick as moved significantly from its center position.
