Is s-bus the same as i-bus!!?? Newbie still very confused - please help!

mackerel · Jul 16, 2018

I am trying to setup my first drone - Diatone GT MK-3. I have bought everything I think I need but I think I may have an RX/FC incompatibility issue. I have a Turnigy TGY-i6 TX (bought that as it was the cheapest and included RX) but discovered that the included RX does not have S-bus which is what I THINK the Diatone FC uses (can anyone confirm!?). So I bought an X68 receiver, which I have now discovered does not mention S-bus, only i-Bus - are these the same!!?? Also - it is a couple of mm to mount nicely in the drone.

I am thinking I may have made a false economy in the Turnigy and might be better off returning that and the X68 - unless anyone can advise about driving S-bus from my RX??

Thanks in advance people - this stuff badly needs some documents!!! Please point me to any that exist.

Here is my setup - I have at least bound the TX/RX

They are basically the same but developed by two different folks. Ibus is different in that you don't have to calibrate end points whereas with sbus you do

Thanks for the replies - so maybe I am OK with connecting my RX into the drone as I have?? None of the controls are doing anything, so that makes me think maybe not!! Any ideas?

Have you connected to betaflight? (props off) once bound you will need to assign switches for modes, maybe a failsafe switch and for arming your bird.

Hi Wayno52, what is betaflight!!?? I haven't assigned any switches, failsafe etc. I was going to do that once I saw some signs of life from the motors.

Wayno52 · Jul 17, 2018

Ah OK, once bound you will need to set it up to be able to fly. You will need to download betaflight configurator to your laptop (assuming you have one) and then set up your quad.
Hope this helps

You will also want to set up your tx.

Just please remember to do all of this with no props on. That's a powerful little bird.

Thanks so much for the links, this looks really helpful!! I do have a laptop - hopefully it will be obvious where I plug it in to the drone? I think there is a micro-USB connector on it?
