Powering X8R servo ports via SBUS port

[Devon Slopes]

I've finally filled up all the available servo connectors on an FrSky X8R by adding a tow release to "full house" glider (it also has a lost model alarm). Now, whilst I could power the rx by putting a Y-lead on one of the servo sockets, that SBUS (or indeed the RSSI) socket looks very tempting. I opened up the rx to check if it was on the same positive and negative buses as the servo ports, but its hard to tell (I suspect connections are buried in the PC boards somehow).

So, my question is, has anyone powered the servos connected in the normal way to the X8R via the SBUS or RSSI ports? Or, does anyone know if the internal connection of the SBUS and/or RSSI ports is similar to the one between the servo ports.

Thanks, Devon.

If you only need power to the RX, then use a Y lead. Because if it goes wrong that £28 up in smoke. if you have no Instructions, go to the FR SKY website and down load them. it might say if you can power the rx from other pins

I have powered X8Rs via any of the available ports, although I do have 1 that refuses to operate that way using the SBUs one for some unknown reason so on that one I do use a Y lead.

You should be able to power the rx via the x bus port because if you were to use sbus servos they would all get their power from that one connection! also the y lead is a perfectly easy simple and safe method to use.

Belated thanks for the advice folks.
