SBus questions

[Don]

Being an electrical newbe, I am unable to find out what to buy if I have an sbus capable receiver. All the diagrams I see just call out "hubs". Do I need a decoder cable to run analog servers, what are these "hubs"? Are they come kind of splitter? Thanks for the help!

Hey Don,

To avoid the tail shaking the dog, what are you trying to do with the Sbus? Sbus methods work really well for some applications, and make a lot less sense for others. I'm happy to help, but a better idea of your goals would be GREAT.

Looking at a Slow Bipe and a lot of the micro receivers are sbus. I didn't know squat about it since I am an electric newbie. I don't think sbus saves any weight, and probably adds a little bit. I just wanted to know how it works, what do you buy, cables, decoders to run analog servos, etc., etc.

Sbus servos in general cost more than regular pwm servos and I believe 9gram are hard to locate.
SBUS is good for connecting to flight controllers (mainly quads).

FrSKY makes an SBUS to PWM decoder.

To use the decoder a channel changer is needed.

Generally speaking - SBUS is good for connecting with a Flight Controller - as in "drone" applications - and for very very large aircraft with very long servo leads. For aircraft with wingspan of about 1 meter or more I'd use X6R or X8R unless I was VERY tight for space than then I'd use X4R.
