Here's my standard SBus harness for a bipe, (mono only has two short cables to wing servos).

The very short cable goes to the SBus output on the receiver and the two connectors on the hub are one for the rudder servo and one for the regulator output. A second regulator output goes directly to the receiver to provide some cable redundancy. I use a 7.2v regulator even though I use HV servos so that the feel is the same throughout the battery discharge.

I use Hansen Hobbies 0.1" servo strip PCB for the hub and their mini Y Harness boards for the Y connections.
