Does this device do both channel changing as well as decoding? Are use the Futaba S bus system and I need to extra channels for my eight channel receiver. I plan to use the S bus to get these two extra channels. It used to be that you needed two things to do that end a decoder as well as a channel changer. But this new SBD-2 Looks like it combined those two. Am I correct? I want to make sure I’m buying the correct items. This is going in a 91% Lazer, so I’m really not concerned about the size or weight. Any help would be greatly appreciated. Thanks in advance.
