so i installed a payload drop on my P3A by combining two different mods. so i bought the splash drone payload drop (link) and the retractable landing gear from RCDH (link). So what i did is take the wireing harness from the ratractable landing gear and installed as normal but i only installed the Waterproof payload release for splash drone where the servo for the right side of the landing gear would go. then i threaded the wires through the phantom to clean it up. Once i tested it and had it all working i attached the payload release to the bottom of the P3A
