[SOLVED] Futaba S-Bus

[Jman841]

Hello,

I just switched from using DSM2/X Sat's to using FrSky x4R-SB rx's running S-Bus. The switch was pretty simple and everything is working perfect except for my throttle channel. My ESC (HW Platinum V3 50a) is doing a slow 2 second beep after startup, indicating it is not receiving a signal from the unit. Everything else is working perfect except the throttle signal.

Unfortunately, the Spirit Software does not show the throttle channel for some reason which would help a lot in diagnosing this issue.

My Tx is showing that channel 3 (Throttle channel on FASST) is outputting a signal and the pitch is linked directly to the throttle which is working correctly.

I can not figure out why the ESC is not seeing a throttle signal. When I put the DSM2 Sat in and use the old transmitter, changing nothing else, all is fine.

Any idea's?

Got it!

Throttle channel has to be plugged directly into the Rx.

Great, with following version you will be able to plug it to either rx or the unit.

Awesome! I will prefer that so I can have the ESC power right to the unit. i could pull the pins out and put it there now but easier to just wait.
