Non S-Bus servos can be used with the decoder extensions. Each decoder has leads for 3 servos. The decoder is plugged into the S-bus at any hub. The decoder is programmed so that it knows what function is on which of the 3 leads. The decoder handles the serial communication thus allowing use of any digital or analog servo.

On the other hand, S-Bus servos are programmed individualy then plugged into the serial bus at any hub location.

The jet must have an S-bus receiver. Extensions, hubs, and s-bus servos are plugged into the s-bus which is all plugged into the receiver using the s-bus port. Non s-bus servos plug into a 3-lead decoder which is then plugged into the s-bus hub.
