Default YGE 120LV and vbar governor

Ok, so I got my goblin 500 up and running nicely, slight tail oscillations. These I might be able to dial out with gain, but my vbar log says "governor input glitches" all over the flight, the remainder of the log is ok with good health, no other messages.
I have the YGE 120 LV (vbar ready) and vbar governor active, with internal BEC. So I had my rpm sensor only with the orange wire (which is different from the rpm sensor between my 160HV YGE and vbar on goblin 700) , but I guess I need also the brown (=ground wire), and keep the power (=red wire) out of the rpm sensor port? Could this cause some tail oscillations or bigger problems with more agressive flight (funnels etc.)? I'll change the rpm sensor cable with the ground wire included and report on the result. Appreciate the input, thanks
Jan

Ok, for those interested: I redid my wiring, installed a ferrite ring on the BEC wire of the YGE, and put more space between motor wires and rpm/bec wires from YGE. Result: glitches gone in log! My rpm wire has orange wire only, I removed the ground wire.

As for the tail: I apparently suffered from an issue already noticed in the Goblin 500 forum: the bearing in the tailfin was not glued from factory, so I put some CA on that bearing, tail is rock solid...
