I don't have any knowledge of the flight controler that your using but on the KK1.2 you have to put throttle at 100%, press and hold two buttons on the controller, connect the battery, wait for the beeps, reduce throttle to zero, wait for the beeps and release the buttons. This calibrates the throttle at both minimum and maximum positions. Quite possibly different on your board but maybe that is your problem.
