The Multi Distribtuion is designed to allow ultra precise digital adjustment and matching of up to 4 servos connected to a single channel. The Multi Servo Distribution also offers the option to power the connected servos via an auxilary battery pack and switch harness (sold seperately) independently from the receiver. The Multi Servo Distribution is ideal for precisely matching servos to compensate for variations in linkage geometry, servo travel variations, and for varying servo neutral positions. It is designed for use with all Standard and Digital Servos.
