SBus
Depending on the servo, it could be either HV or not. Look in the description for the HV designation.
SBus servos need to be programmed to a channel assignment. This can be done with a programming device or through the transmitter in the case of the 14 and 18 series transmitters.
An SBus servo is just a servo if used with a non SBus receiver or with an SBus receiver but plugged into a regular channel port.
If using for SBus you will need either hubs or home made leads with as many female connectors as needed to get the job done. I usually make my own hubs to get them custom fit for the purpose.
If using non SBus Futaba servos for SBus you will need the decoder. I don't believe other brands can be used for SBus purposes.
