Kyogre plane Free 3D model

sorry if I spelled it wrong. No rig. Want rig? In search, type in 'by vanhua870' then click on free, then on rigged, then on kyogre rig. Make rig and mesh connect by control p, and then keep transform, then control p again, and press 'with automatic weights.' Please tell me if rig is not working. model is not mine, but rig is.
