The trigger assembly on the Flydigi Apex 4 is responsible for detecting analog input when the trigger is pressed. Over time, the trigger mechanism may wear out or become damaged, resulting in inconsistent inputs, a lack of response, or a trigger that feels physically loose. This guide will walk you through safely removing and replacing the trigger assembly. Before beginning the repair, ensure the controller is powered off and unplugged.
