The SBus is actually identical to the normal channels, the only difference is the conection to the Rx, I for example used the radio to program each servo for center so I do not use the subtrim function, same as for direction, the the chanel number I assigned with the Function button, but each servo has a channel, it does not matter if it has one conector, the servos come with a decal you can place close to the servo, and if for any reason you would like to change something in a servo, you simply enter the code of the servo and reprograme it, it does not have to be disconected from the others, I really like the system.
